And a freaking horizontalness indicator. I had to scribe mine.

Agreed.............trying to judge it by feel is a nightmare.

Sixto, he's talking about that IP lock tool that we were discussing above........prevents rotation of the IP when it's removed from the timer.

No, he rotated the crank 360 degrees while keeping the cam stationary. There is only one mark on the cam.

No trial and error. That will be a nightmare. At the risk of paperweighting, I'll share what I did. I found a brass hose barb fitting, probably a 5/16 barb, that fit closely in the port hole. I used a hacksaw to cut a slot in one end to engage the tang. I cut the length of the barb such that the port plug would hold it in place once the tang was engaged. To turn the pump cam, I put a thick soft vinyl cap over the splines. I used waterpump pliers to turn the cam with one hand while positioning my makeshift tool with the other. Clearly a piece of solid brass barstock would be better than my hose barb, but I used what I had on hand. I'll try to post a picture of the tool tomorrow.

I'm a mechanical engineer who has been in the heavy duty engine design and development business since 1985. I started my career with Deere and Company, then went to Cummins, then on to a small R&D company, now a partner in an even smaller company.

Yeah, the centering tool is a bit of a mystery to me. On my engine there's something called an "assembly cage" that was discontinued later on. The centering tool looks (in the picture, I've never actually seen one) suspiciously like the assembly cage. I'm guessing the tool is just deeper than the cage so when it is installed it presses against the sprocket/timer and holds it in place. The tool is supposed to be installed before removing the pump. What I did was to take out my assembly cage, wrap about 10 turns of electrical tape around its snout so that when I put it back in it pressed against the sprocket. Then I took out the tensioner to keep from having any excess side load on the sprocket. Then I removed the pump. I didn't have any problems at all this way. But this is not a suggestion to do what I did... for obvious reasons.

A piece of heater hose ought to work well to protect the pump splines from the pliers when turning the cam. It doesn't take a lot of force to turn, so you don't need to squeeze down very hard.

Not worth the effort. I can send him the proper locking tool to be there in two days, if necessary.

If true, then I agree there is no second case as defined in post #65. But, I'd sure like additional confirmation of this fact.

EPILOGUE - The paperweight rolls - uphill even!!

I finally got everything buttoned up yesterday, and the car runs great. Thanks to all for your help. These forums are truly invaluable.

Yes! Great news.

Yep, good job.

Always good to get out of the paperweight scenario.;)

Darn, another parts car off the market, er, I mean congratulations, happy it's back on the road.

;~)
