COMPLETE MANUFACTURER REFERENCE / 10 FAMILIES
Two familiar names across many diesel generations.
Zexel and Diesel Kiki identifiers can send you down an entire family tree of VE, PE and PFR equipment. Their physical shapes and control arrangements differ. The best service inquiry starts with the complete pump marking plus the original engine application.
Have a pump identification plate, an engine model or a photograph? You have enough to start the conversation. We will help review the information and discuss available service or parts options for the exact component, without assuming every model is serviceable.
More identification insights and technical background
Diesel Kiki is the older name many owners remember when discussing Zexel injection pumps. The VE/NP-VE and VRZ designations share shelf space in a wider catalog of P-type, PF, PFR and TICS-related identifiers.
Making sense of Zexel and Diesel Kiki names
Historic maker names and family labels help narrow a search, but they do not establish pump interchangeability. Some control and calibration differences are not obvious from the housing.

Zexel Diesel Kiki history, identification and practical service questions
Diesel Kiki to Zexel to Bosch: The Long Way Home
Diesel Kiki was founded in Japan in 1939 to build Bosch-licensed injection pumps. It became a major Japanese fuel-injection maker and supplied a long list of Japanese engine builders, from Isuzu to Komatsu. In 1990 it renamed itself Zexel.
Then the story came full circle. Zexel became Bosch Automotive Systems in 2000 and Bosch Corporation in 2005. So a Zexel pump is, in a real sense, a Bosch design that took the long way home.
Did You Know? That full-circle history is why many Zexel pumps carry a Bosch cross-reference number on the tag. The pump was designed in the Bosch tradition, built in Japan, and later folded back into Bosch, so all three identities stuck.
We test, rebuild and calibrate Zexel and Diesel Kiki pumps from compact tractors, skid steers, forklifts, excavators and the Isuzu trucks that keep American deliveries moving.
How to Identify a Zexel Pump
Zexel nameplates are dense, but they are honest. Learn to read two things, the three numbers and the NP- code, and you can identify almost any Zexel pump from a phone photo.
The Three Numbers on Every Zexel Pump
| Number | What it looks like | What it tells you |
|---|---|---|
| Zexel number | 10xxxx-xxxx (e.g. 1046xx- on a VE, 101xxx- on an A-size inline) | The exact pump and calibration, as Zexel built it |
| Bosch cross-reference | 9 400 61x xxx (inline), 9 410 61x xxx (PFR), 9 461 6xx xxx (VE) | The Bosch catalog number for the same pump |
| Engine-maker number | Isuzu 8-9xxxx, Komatsu 6xxx-71-xxxx | The number your dealer’s parts counter uses |
Any one of them can get us started. All three together, plus a photo, removes the guesswork.
Reading the NP- Nameplate Code
Zexel type codes start with NP-, followed by Bosch-style lettering. NP-VE4/11F… is a four-cylinder VE rotary. NP-PFR… is a plug-in plunger pump. NP-TC S4MD110 is the code you will find on the MD-TICS pump on an Isuzu 4HE1. Inline codes follow the same logic, so a PES6A is a six-cylinder A-size inline.
Owner’s Tip: Photograph the whole nameplate in daylight, then any sticker the engine maker added nearby. Isuzu and Komatsu numbers often live on a separate label. Send the photos with your repair inquiry and we will confirm what you have before you ship.

Family-by-family guidance
These are all the pump families named under ZEXEL / DIESEL KIKI in DCT’s source register. Each note focuses on getting the component identified, separating a symptom from a diagnosis, and making the next step simpler. A family being listed is not a promise of available inventory, parts interchange or repair acceptance.
ZEXEL / DIESEL KIKI / PUMP FAMILY
HD-TICS
A cold-start complaint or unexplained stumble on an older machine is frustrating enough without also guessing at its pump family.
The HD-TICS label deserves to be read in full. Keep any suffix, drive-end marking and engine-manufacturer number with the HD-TICS reference. Names reused across decades and applications are not proof that two assemblies have the same settings or parts.
Distributor-style equipment has its own timing, fuel-supply and calibrated delivery questions. A visually similar pump can conceal different governor, control or drive configurations.
Before you remove, replace or ship it: Document cold-start behavior, external leaks, air-in-fuel evidence and the existing timing marks before any removal. Keep original linkages and fittings organized.
Explore HD-TICS: identification, symptoms and next steps
Before you decide it needs a pump
Distributor-style systems combine fuel delivery and distribution in a calibrated assembly. Exact governor, timing advance and application details may matter as much as the broad model label.
Owners of older Japanese diesel engines and specialized equipment may encounter a no-start that resembles a pump failure. Capturing the sequence of symptoms and any controller observations before removal helps separate a component concern from the surrounding engine system.
Identify this ZEXEL / DIESEL KIKI family confidently
Keep “HD-TICS” exactly as it appears on the original part or official engine record. Similar words in another maker’s catalog may describe a different installation, governor or test procedure.
Why the manufacturer matters: ZEXEL / DIESEL KIKI documentation and historical naming can overlap with other suppliers. Include the original maker marking and any OEM replacement number. Similar family names are not proof of component interchange.
The observations that help the most
- Document starting and load symptoms, leak locations and fuel-supply condition.
- Photograph the identification plate, drive connection and external controls before removal.
- Record application-specific timing and recent work without attempting speculative adjustments.
Safety and accuracy: Distributor-pump settings and internal components are not universally interchangeable across similarly named variants.
Three questions worth asking before authorizing work
- Did the symptom begin after storage, fuel service or a prior repair?
- Is the complaint present cold, hot, under load or all the time?
- Which full assembly and engine numbers appear on the tag?
From concern to a practical next step
Start with what the operator noticed, add the facts an independent shop has already measured, and photograph the full unit plus every number. DCT can then discuss whether identification help, additional engine-level testing, a supported component evaluation or a parts inquiry is the appropriate next conversation. The exact work and receiving location are confirmed before anything is shipped.

MD-TICS
A familiar-looking distributor pump can still be a poor match for a different engine or control setup.
The MD-TICS label deserves to be read in full. Keep any suffix, drive-end marking and engine-manufacturer number with the MD-TICS reference. Names reused across decades and applications are not proof that two assemblies have the same settings or parts.

PE(S)-A / AD
If an engine works hard every season, the costliest mistake may be losing the information that identifies its pump.
The PE(S)-A / AD label deserves to be read in full. Keep any suffix, drive-end marking and engine-manufacturer number with the PE(S)-A / AD reference. Names reused across decades and applications are not proof that two assemblies have the same settings or parts.
On mechanical and in-line pumping equipment, the delivery arrangement, governing and calibrated setup can change the repair question substantially. A good-looking casting is not proof of compatible internals.
Before you remove, replace or ship it: Note delivery-outlet count, governor identification, engine serial and how the fault appears under operating load. Preserve linkage and timing reference information before removal.

PE(S)-K
An older tractor or industrial engine can have plenty of working life left even when a pump number looks unfamiliar.
The PE(S)-K label deserves to be read in full. Keep any suffix, drive-end marking and engine-manufacturer number with the PE(S)-K reference. Names reused across decades and applications are not proof that two assemblies have the same settings or parts.
On mechanical and in-line pumping equipment, the delivery arrangement, governing and calibrated setup can change the repair question substantially. A good-looking casting is not proof of compatible internals.

Explore PE(S)-K: identification, symptoms and next steps
Before you decide it needs a pump
Mechanical injection pumps have installation-specific governing, timing and fuel-delivery requirements. Similar castings and outlet counts do not guarantee the same calibration.
On older Japanese diesel engines and specialized equipment, an intermittent fault under load can be hard to reproduce in the yard. A clear description of the work cycle gives a specialist far more useful context than simply reporting “bad pump.”
Identify this ZEXEL / DIESEL KIKI family confidently
Keep “PE(S)-K” exactly as it appears on the original part or official engine record. Similar words in another maker’s catalog may describe a different installation, governor or test procedure.
Why the manufacturer matters: ZEXEL / DIESEL KIKI documentation and historical naming can overlap with other suppliers. Include the original maker marking and any OEM replacement number. Similar family names are not proof of component interchange.
The observations that help the most
- Photograph the full nameplate, control linkage, governor section and drive interface before removal.
- Record whether the fault is a no-start, uneven idle, surging, smoke or power loss under load, and note recent fuel or timing work.
- Capture any relevant engine or equipment serial number so the original configuration can be checked.
Safety and accuracy: Incorrect timing or fuel adjustment can create engine damage. Installation and adjustment should follow the correct service documentation.
Three questions worth asking before authorizing work
- Does the issue follow engine speed, load or temperature?
- Has timing or linkage adjustment already been changed?
- Is there a written record of previous pump work or substitutions?
From concern to a practical next step
Start with what the operator noticed, add the facts an independent shop has already measured, and photograph the full unit plus every number. DCT can then discuss whether identification help, additional engine-level testing, a supported component evaluation or a parts inquiry is the appropriate next conversation.

ZEXEL / DIESEL KIKI / PUMP FAMILY
PE(S)-P / PD
A mechanical pump that has served for decades deserves the correct original calibration, not a hopeful near-match.
The PE(S)-P / PD label deserves to be read in full. Keep any suffix, drive-end marking and engine-manufacturer number with the PE(S)-P / PD reference. Names reused across decades and applications are not proof that two assemblies have the same settings or parts.
On mechanical and in-line pumping equipment, the delivery arrangement, governing and calibrated setup can change the repair question substantially. A good-looking casting is not proof of compatible internals.
Before you remove, replace or ship it: Note delivery-outlet count, governor identification, engine serial and how the fault appears under operating load. Preserve linkage and timing reference information before removal.

PF
The component may look simple on a bench, but its original position and engine arrangement are not disposable details.
The PF label deserves to be read in full. Keep any suffix, drive-end marking and engine-manufacturer number with the PF reference. Names reused across decades and applications are not proof that two assemblies have the same settings or parts.
Individual pumping elements and unit-related systems demand special attention to the exact engine installation and adjustment arrangement. A familiar family word alone does not establish interchangeability.
Before you remove, replace or ship it: Photograph the installed layout, element numbering or configuration, fuel connections and any accessible part stamping. Follow the manufacturer procedure for safe removal and timing.
Explore PF: identification, symptoms and next steps
Before you decide it needs a pump
Element-style systems must be considered in the context of the engine and the individual pumping position; a stand-alone element number rarely tells the whole story.
For older Japanese diesel engines and specialized equipment, a complaint isolated to one cylinder or pumping position needs to stay tied to that installed position. Mixing several parts on the bench can erase the evidence that would have saved diagnostic time.
Identify this ZEXEL / DIESEL KIKI family confidently
Because “PF” is a short designation, include the ZEXEL / DIESEL KIKI maker name in searches and keep the entire identification plate in any inquiry. A short letter code is easily mistaken for unrelated equipment terminology.
Why the manufacturer matters: ZEXEL / DIESEL KIKI documentation and historical naming can overlap with other suppliers. Include the original maker marking and any OEM replacement number. Similar family names are not proof of component interchange.
The observations that help the most
- Identify the installed position and photograph the element, mounting and fuel connections before disassembly.
- Retain orientation and timing information in accordance with the OEM removal instructions.
- Record which cylinder or bank showed the complaint, rather than assuming every element needs replacement.
Safety and accuracy: Do not transfer individual elements between engines without verified application and calibration instructions.
Three questions worth asking before authorizing work
- Which installed position or cylinder does the assembly belong to?
- Are there differences between the original number and the replacement listing?
- What manufacturer timing or setting reference applies to this engine?
From concern to a practical next step
Start with what the operator noticed, add the facts an independent shop has already measured, and photograph the full unit plus every number. DCT can then discuss whether identification help, additional engine-level testing, a supported component evaluation or a parts inquiry is the appropriate next conversation.

PFR
When individual injection elements are involved, keeping their identity and installed context together matters.
The PFR label deserves to be read in full. Keep any suffix, drive-end marking and engine-manufacturer number with the PFR reference. Names reused across decades and applications are not proof that two assemblies have the same settings or parts.
Individual pumping elements and unit-related systems demand special attention to the exact engine installation and adjustment arrangement. A familiar family word alone does not establish interchangeability.

VRZ
On equipment that has already changed hands, an identification plate can tell you more than the service history.
The VRZ label deserves to be read in full. Keep any suffix, drive-end marking and engine-manufacturer number with the VRZ reference. Names reused across decades and applications are not proof that two assemblies have the same settings or parts.
Distributor-style equipment has its own timing, fuel-supply and calibrated delivery questions. A visually similar pump can conceal different governor, control or drive configurations.

PE(S)-Z / ZW
An older tractor or industrial engine can have plenty of working life left even when a pump number looks unfamiliar.
PE(S)-Z and ZW are retained together exactly as supplied. Do not fold these into the PE(S)-A or PE(S)-P entries: the complete Zexel/Diesel Kiki code must guide parts and calibration research.
On mechanical and in-line pumping equipment, the delivery arrangement, governing and calibrated setup can change the repair question substantially. A good-looking casting is not proof of compatible internals.
Before you remove, replace or ship it: Note delivery-outlet count, governor identification, engine serial and how the fault appears under operating load. Preserve linkage and timing reference information before removal.
