    Ford 930a finish mower

    I keep having a problem with the rear blade pulley. The pulley is cast with a steel sheave in the center held together with two 1/4-20 bolts. I keep shearing the bolts and the two parts eat each other up in no time flat. I even went to grade 8 bolts and it does the same thing. I would like to...

    Bearing shims

    Well it's not real clear to me either. When I talked to him about the +-005 he simply said it's a half. (same thing you said) After that he said the rod journal was 3 out and that's on the outside. I would have low oil pressure. He had seen people put much worse cranks back in there tractors but...

    To TheOldHokie, Thank you for the school lesson. I took the crank to the machinist. He measured it and found that for the most part the crank was ok but did find that one of the rod journals was out .003 with the rest being out .001-,002. He stated this was on the outside tolerances. He also...

    Bearing shims

    Can't find a date on them but I knew it was news print when I saw page 3 on one. They are as thin as rice paper. Much thinner then bible paper. The threw a couple of the bearings in the trash last fall when I took this apart. Wish I had looked closer then. I wasn't focused on the old bearings as...

    Now I understand. Thank you for that explanation. Reminds me of that old song. “I can see clearly now the rain is gone.” My God I’m getting slow in my old age.

    Found another paper shim stuck inside a bearing cap. Thin little suckers. http://forums.yesterdaystractors.com/photos/mvphoto16593.jpg[/img]

    Bearing shims

    It’s all about my confusion. I understood the tolerance to be .005 but your saying .001. When you placed the 5 at the end of my measurement of 2.238 being .010 under I was a bit taken back when you wrote 2.2385 you jumped from the thousandths to the ten-thousandths place. If this is correct I...

    Bearing shims

    BOB SAID “Also have the main bearing areas checked for size and "out of round, and have the "line bore" checked” Where exactly is that in the FO-4 manual or the 3730-47J Service manual or the 3729-50-M Operator’s manual? I also have the book “How to restore Ford Tractors” by Tharran Gaines and...

    Bearing shims

    Well this is all true. The one thing I can't do is turn the crank. I can do pretty much everything on this tractor but I can't turn the crank. I hope I don't have to. It seems to be fine but I guess I don't really know. Keep ya posted on outcome

    Bearing shims

    I do appreciate your input and I’m not going to reassemble before I know it’s right. I might be a slow learner but I’m not foolish. Still working the problem. I don’t think the mechanist was steering me wrong. I know he is a good mechanist and has work lined up to no end. I think his approach...

    Bearing shims

    The FO-4 that I have states the diameter from factory is 2.248-2.249. This crank was taken down .010 and all bearing taken out of it were .010 bearings. Now the way I see it is .010 from 2.248 = 2.238. Which is what I come up with. The manual gives a range of .005 so I think .002 qualifies as...

    Bearing shims

    I hate coming to this site. Every time I come here I find enough testosterone to make my tractor run all by itself. I stopped in last fall to talk about this rebuild and found the advice all over the map as arguing ensued so the tractor just sits. When I started this project I went to the...

    Bearing shims

    I went to the mechanist and talked to him about this. He told me that newspaper shims was an old timer trick to quite knocking. Often used to sell an old tractor to some nitwit like me. He said the crank has only been turned once so the best option is to turn it to .020 and put in new bearings...
