Wow what a great job. I like everything about it, the equipment used, and shop layout in general. It's really nice to work with clean and dry assemblies isn't it?

Everything Dave does is first rate. The tractor will be in like-new condition; the paint job is likely to be better than new. Dave does have a very clean shop in which to work. We all look forward to more photos. Thanks, Dave! GWH

Replied by Dave on topic Transmission input bearing
I had to pull the engine again to replace the transmission front bearing. It looked ok to use again and especially when I checked the price, $250.00. The upper transmission shaft drooped in front with the used bearing and the weight of the clutch on it. There was no good way to line up the engine and make the links from clutch to flywheel adjust within the minimums specks.

I replaced the bearing with a new one and made a new sleeve for the clutch to slide on as it was too loose. When I got it all back togeather and installed the engine it was much easier to line up. .008 on the parallel surfaces and .011 on the radial.

Rebuilt the carrier rollers and made new shafts and bushings. Also made special shimm washers to take up the wear on the length of the rollers. It's a lot of work but I'm having fun doing it.

Hello Dave. Thanks for the pics. I enjoy watching your projects. I also pick up some good ideas from the background of the photos. Your crane for the forklift from last yr has a lot of good features i am looking to use when i build mine.

Please keep us up todate with the 65 and post some more pics when you have a chance.

The carrier roller shim washer width depends on the wear on the ends of the rollers; inside wear in the end cap collars and the total width between the roller stand brackets with the set screws in tight. My rollers measured 9-1/4” to 9-5/8” in length so I varied the thickness of the washer shims to offset the wear on the rollers ends, the wear in the end cap collars and what it took to centered them on the stands.

Be sure to check if the roller is centered in the stands because if the rails didn’t track center the wear could be more on one end then the other. It is also possible the stands could be bent.

I machined the end caps inside to true them up and bored the hole out larger to take a pilot on the washer shim to keep the caps centered on the shaft. The cap outside square nubs had to be welded up and machined on both the caps and the stands. I should have had them casted.

I like you idea on how to solve the end play problems with the 60/65 carrier roller problem. What I had been thinking about was to make all of the rollers the same lenght along with reworking the washers and then I was going to make flanged bushings to press into the roller. I was going to change the thickness on the flange to adjust the end play. I wish some one would recast the washers, finding a good set of them is hard.
8D-132 I am going to try and call tonight, I hope.
