Realizing that the final settings are done on the engine at marks on flywheel for the TDC's @ 1.736".
I'm in the shop putting the forged body pump and governor back together and setting the rack.
Does anybody have any "Baseline" settings for the lifter yokes, for instance, positioned at the top of the cam lobes ?
Just baseline settings for the bench only.
It's going to be a few more weeks of plowing snow before I will put all of this back on the engine.
Trying, unsuccessfully, to find a 1F8743/1F8747 alignment fixture...


As always, thank you !

I understand that the pump plunger is already rising slightly when the timing marks align for each cylinder, so you could adjust each lifter to the same 1.736" while on the cam base circle and be sure that there would be no interference as you rolled the engine over in the process of adjusting them.

However I think it would be best to leave the pumps off until you get the housing back on the engine and adjust the lifters. Without pumps installed there would be little to no chance of interference.

If you have the ability to set them on the engine, you have no need for the degree wheel to do the initial setting on the bench.
D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time😄

We have depth mics and 9M4567 & 68 to do the settings - on the engine.
We will have the individual pumps off - when we place the pump body on the engine and properly set the height(s) of the yokes.
My 2 elementary school sons are helping me - and we are using the snow days to get some experience in the shop.
Just using baseline settings to show them how it works and how to use the tools & equipment.
Realize we don't "need" the calibration wheel (fixture) we just wanted one to see how it worked.

Thank you for your input and unless we hear differently, we will set the baseline height (on the bench only) on the base of the cam.

Send me your email, I have electronic copies of the rack settings and fuel injection pump manuals.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
