Looking for tappet/delivery valve assembly for ISEKI TE4270 (Diesel Kiki/Zexel PES3K60 pump) — or source for rebuild parts

[vincentcocaultduverger]

Hi all,


I'm restoring the injection pump on an ISEKI TE4270 (French-imported tractor, serial 024416). The pump is a Diesel Kiki (Zexel) unit:

• Type: NP-PES3K60C410RS1N66
• Part No.: 104303-2340
• Serial: 749L715044
• Ass'y No.: 6215600-0040
• Governor: 425–1300 RPM

I need to replace/source the roller tappet assembly (with spring and delivery valve holder — photos attached) for this pump. I have the exploded parts diagram (Fig. 17A) but not the matching page with individual part codes for items #21–32.


Has anyone here:

1. Worked on this exact pump or its close relatives (PES3K family, ISEKI/Isuzu 3AE1 engines)?
2. Sourced tappets/delivery valves for it — new, used, or via Bosch's cross-reference system?
3. Got the parts catalog page (TE4270, Fig 17A, p.41) they could scan for me?

Happy to share more photos or the full parts diagram if it helps. Any leads — dealer, part number cross-reference, or even a donor pump — greatly appreciated.

Thanks in advance!
