I’ve just replaced seals and was going to refit after removing in near darkness after work earlier this week and noticed the play in the shaft. Is this normal or is it horribly worn?
It is common that end of shaft is slightly deformed like in video, if there is too much play it will of course cause noise and eventually perhaps break (not heard)...
Okay thanks. Not sure if the shaft is machined like that or it’s worn like that. It’s running now and not overly noisy from my limited diesel experience. Best of all it’s mot leaking either. There does seem to be a bit of lateral play from end to end of the hole, but it’s working for now. Only the bottom bolt that’s a total pita if it needs to come off again
just to clarify, that -o- shape piece is meant to include some tolerance so shafts may have some some misalignment. Because of asymmetric power transfer shaft will then wear on opposite sides in direction of rotating. Bottom bolt is not bad if you remove serpentine belt and fuel lines/clamps.
Well sadly it is still leaking (in fact worse) after test drive though sadly from a different pump, and the fuel feed hoses seem to be leaking too now. There weren’t any replacement washers for them in the kit unfortunately. Looking at the clamp that holds them firm I think that may also be damaged too. Looks like there should be a sort of finger piece on it that appears broken off.. PITA.
always change o-rings when replacing anything there... additionally clamp which holds hoses in side of hp-pump has originally a foam like shim under the plate.
