i'm starting a rebuild on my dads 12 valve. he bought the truck cheap knowing it needed a head gasket. but there was so much a/f in the crank case it ate the turbo bearings. so i'm gonna do the bottom end in it. just lookin for any tips or hints cuz its my first full rebuild on one. also any ideas on how to set it up for mileage on a budget. i was thinkin a hx35 hybrid, mild fuel plate, bosch 42hp injectors, and a timing advance.

oh truck is,
1995 ram 2500 5 speed, 2wd ext cab long box. 215hp pump

thanks

in frame or out.

If you're pulling it (recommend) make sure you have a GOOD engine stand. I used an OTC Motor Rotor which hold two ends on my 96. And a good cherry picker. I had better luck unbolting the motor mounts from the block as well to pull and reinstall. Crank is heavy. Make sure the piston cooling nozzles are all in and are a press fit into the block so one doesn't fall out after reassembly. Two of mine were broken but still in the block. I did it without the FSM but wish I would have had it.

rebuilding it out of the truck. what size of dowels are used for holding the lifters? also what is stock timing? and what would be a reasonable advance for mileage?

thanks

Contractor

Dowels are 1/2" I believe. I think stock timing is 12

Contractor

You can also use hose clamps to hold the lifters up since you can take the tappet cover off.

stock timing varies from 12.5 to 13 depending on year and application. call cummins with you engine number and CPL number and they will tell you what stock is

infidel

My CPL tab says what the stock timing is supposed to be right on it.
15.5 is better though for better economy and more power.

ya stock timing said 12.5. is there no keyway in the pump gear? i dont have much experience with the p-pumps. mostly worked on ve and vp.

Tate

You don't need dowels to hold the lifters up, just roll the engine upside down to pull the cam.

Unless your pump has been swapped, you'll have a 175hp pump, not a 215.

cj360trider

no there is no key in a p pump shaft. there is a keyway in the shaft but none in the gear

1dumrednek

it says 215 hp on the id plate on the side of the timing case. i thought that sounded high for a 95.

1dumrednek

what would be something good to make a cam/ lifter tube out of and what size?

Tate

The engine may have been swapped, or maybe just the timing case. In either case, the pump could be something else. If its a 215 pump, the tag on the side of the pump will have either 0 402 736 887 or 0 402 736 913.

ya i can turn it upside down but i wanna make one so i have it in case i gotta do one in frame.
