is anyone on here capable of installing the F lower crank bearing in a D block?

 

[bald-guy]

F bearings have a tab on them to keep them from rotating in the F block.
That would have to be ground off to intall into a D block.
Also the lower F bearing is shorter than the D bearing.
Not as tall, I mean.

 

[nickzom]

there is machine work that needs done to install it though, right?

Correct, I know Zeeker and Mike72 has done it. Here is Mike's thread about it.. http://www.mytractorforum.com/showthread.php?t=137085

If you are going to put it into where the bronze bushing is in the lower part of the crank case, yes it will have to be machined to accept the bearing.
Some of the old armature plate bearings were short ones, some were longer, what ever bearing you put into the D block will need to go with the block to the machine shop.
The bearing will need to go into the block far enough so the oil seal still seats.
I can't do it, no machines to do it with.
I have had it done years ago, a buddy worked in a machine shop at the time.

 

[nickzom]

so, any automotive machine shop should be able to do it?

 

[bald-guy]

They should be able to do it.
The factory did it on snowblower crankcases back in the 80's.

 

[nickzom]

i will have to call around then.

Most automotive machine shops will not be able to do that, you will probably have to take it to an actual machine shop. The auto shops will not have the machine necessary to do this type of work.

you think?

One time I needed to get some LB bearings and the shop didn't have them. I went to an industrial supply house and they measured the bearings I had (old LB) and they had some that were basically identical to the LB ones, but didn't have the tabs. They were remarkably cheap, too. I think I may still have them in a can in the basement.

Are the tabs necessary? Can't they be machined off? The crank is still going to spin in the bearing...someone correct me but the "tab" just holds the bearing case from spinning....no?

yes..

I think it also lets oil that pools in the channel to run into that hole to help lube the bearing.

Ah...yep I knew that so really you'll need the machined notch plus a chanel to get the lube in...makes sense. Shouldn't be too hard for a CNC with a small bit.

Zeeker thread???


Zeeker and Mike72 impress the heck out of me with their work.
