Been putting off the pretty important task of timing the pump lately, so today I jumped in on that. This task is way easier with the engine on a stand. Used the special socket to pull the first 2 delivery valves on the injection pump, and timed it using a homemade dial indicator adaptor. If anyone ever needs to do this, a Cummins oil pan plug is the same thread as the delivery valves. I drilled hole through it wide enough to fit the body of the indicator, and drilled and tapped a small hole for a set screw. Works great, and saves 70 or 80 bucks
Took me a while to find all the specs for base timing for this pump, the engine data plate has info for wrong year and size of injection pump. So I ended up using the Bosch timing chart to set it from no lift. Decided on a conservative 18 degrees of advance, with the lash in the gears it's probably closer to 18.5 or 19. Translated to roughly 232 thousandths of an inch barrel lift
While I had the cover off, I addressed the dowel pin that likes to fall out and grenade the gear train. No need for fancy expensive kits, a few smacks with a hammer and punch and that pin isn't going anywhere
Finally got the front cover cleaned up, front main installed and cover sealed to engine. Had a hell of a time getting the seal in, and It is almost definitely going to leak, but it'll do long enough to do the cam break in, and I can replace it before I drop it into the truck. I want to install a speey sleeve, anyway
Other than that, I finally started throwing some money at this thing. Ordered a set of 5x.014 SAC injectors from DFI, a high mount AC bracket from Adventure Vehicles Northwest, and will likely have a turbo and manifold coming early next week. Decided against the ATS 3 piece manifold, as I read lots about them cracking. Going for a Steed manifold with a T4 flange. Also still working on turbo selection, basically narrowed it down to an S362 or 364, should compliment the injectors nicely to get a decent 450 to 500 horse. That's all for today, hopefully tomorrow I can get the headstuds to their final torque, and clean up and install the valve covers
