P-pump Delivery Valve springs

[RC_98’12v]

Ok I may have screwed up. I was swept g the d-valves and decided to polish up the holders. Well I got some of the springs mixed up. I didn’t think anything about it until I noticed they have shins on the springs. Please tell this isn’t going to be that big of a deal. Thanks for any advice

Seriously? Nothing? For no one? Come on guys.

Don't know what swept g the d-valves means for one thing. Common sense would say that shims are added for the differences in spring strength. I suggest you contact an authorized Bosch repair shop.

Sounds like your going to need access to a spring tester to match the springs to the shims.

Oh I didn’t mix the shins up just the spring to holder/barrel or does that even mater?

The shims are there to equalize the ship pressures so the springs need to be matched to the correct shims. A shell game of sorts. There could be multiple scenarios of which spring goes with which shim. How many springs are there ?.

Well, ya. Please clarify what swept g the d-valves means.

alright smart as if you can't deduce( that means figure out) by the context obviously it was a typo and I meant to type SWAPPED. I swapped the DV’s and decided to polish the holders. I didn’t get the springs back in the same order, but the shims stayed with their original spring.

Auto correct, Swapped.

Well, sorry to say, you may have screwed up..... It is that big a deal, unfortunately. Those springs are there to match fuel flow to each injector, and have to be calibrated by a flow bench, if I recall correctly.... that's why the shims are there to compensate for each spring length and tension to match fuel rates going to each injector.... I mean, you can put it back together, and it'll run.... but it may(probably will) lope like a cammed big block gasser... and it may be fine... but I'd wager at idle it's not gonna sound sane....

Just following up. It had absolutely no effect on the engine. I didn’t lose any shims I just mixed up which spring went with which holder. Again it made no difference with idle or anything else.
