1964 Ford 4000 Industrial Diesel Restoration #2

Act I Scene II:
Rebuilding the motor.

Here’s the replacement motor. Although I am told it’s been rebuilt I’ll tear it down and send the block in to be hot tanked and magna fluxed. I don’t want any surprises.

First problem. The cam shaft won’t come out. I have the pump gear off the back end and the bracket behind the timing gear at the front end unbolted. When I pull from the timing gear end, the shaft slides forward easily. But when the rear journal comes to the center opening and the center journal comes to the front opening it stops solid. My manual says the shaft pulls out forward. It can’t move to the rear because of the timing gear. The timing gear is secured with a snap ring and the gear is to be removed after the shaft is out. I think the timing gear is pressed on and would be damaged using a puller

I just got back from the shop. I quit standing back and looking at the engine as a hunk of metal and said to myself “If I were this engine what could I do to screw this guy up?” The answer came back, “ I would be a lifter sticking up and hitting a cam lobe.” And there it was. The lifter just before the center opening was hitting the rear lobe as it tried to pass by and stopping it. A slight tap on the lifter and it was down and the cam slid right out, just like Willie after his 90 seconds of glory.

It’s apart and I am not aware of anything wrong. Pistons have a gummy substance on them and black oil in the oil rings but no carbon on top. Crank journals are clean and shiny, no sign of wear there or on the bearings. I do see black oil on all the bolts that I removed. Seems strange for an unused rebuilt.

I do have some concern about the rust. If you read the first post, you know that the motor sat outside on a pallet for two years with no pan or head, open to the weather. Most of the rust seems to be a patina of rust instead of flaking rust, (except for part of the timing gear[pic.above] on the cam which had been partially submerged in water) I polished one of the cam lobes with fine steel wool and there is possibly some pinpoint pitting. I checked with a local diesel mechanic for the hot tanking and magna fluxing. I showed him a picture of the motor before dismantling and he said it would need an acid bath and then of course the crank, cam, etc. would need a re-grind, etc. etc. etc. I do have the original motor that only had a few hours on a complete tractor rebild before it was parked. It’s not apart yet.

Let’s here from y’all.
