I've been checking around for a sprocket rim part #3H2643. Heavyquip lists one for $157 and change plus $90 for shipping. Grace Track Co. wants $217.50 plus $62 shipping. So I called my nearest Cat dealer (Cleveland Brothers) and they wanted like $330 for one. Grace track does say that they will getting Berco's in in 30-45 days for $125 each. Man, do prices vary. I guess it can really pay to shop around.

Any idea what it will cost me to get it cut off and new one welded on? Doesn't seem like a job for a very "novice" welder like myself.

Never did one against the clock but I wouldn't think it would be more than a couple hours worth. Try that Grace Track Co. for a quote.
Main challenge is alignment.

I believe I read where the KoO did this to the HOOD. I do remember seeing pics of his progress on his website. If he canadian this in -40c, I would think that you could do this too, especally in a controlled enviroment as your shop is.

He hasen't posted on his site lately, I am supposing Belle may be visiting...sl

This is the press and the puller that I have been working on in my spare time. The press idea and setup is compliments of EAMassey over on the ACME site. His was much better I admit. I am by no means much of a fabricator/welder, I am just hoping they get the job done. They are not finished, and are a work in progress. I still need to accumulate an enerpac pump and ram. I have been watching ebay for them.

I am expecting the bellows seals to arrive today. I got 2 of the original
3B5730 bellows seals and original 6B6020 gasket rings. I plan to reuse my large metal washers by flipping them over. I also have the correct CAT cement. Can someone explain the proper procedure for cementing and installing this type of bellows?

Right now I am at the point of having the extension tube in place, and will be ready to install the inner bellows then sprocket. Any guidance would be appreciated. Thanks.

Thanks Old Magnet. Only thing is that the attachment you sent to D6Rick is not showing up for me on that link you sent me. Do you still have it? Thanks again.

Yes,
Not all the info will apply but should get you close.

Let me see if I have this right.

1. Cement the new inner bellows to the spacer
2. Cement the new outer bellows to the retainer assy.
3. Cement both sides of the washer gaskets.

Is that correct? I'm cementing one side of each bellows and both sides of the fiber wear washers? Anything else? Thanks.

In relooking at Old Magnet's instructions, I see I have some of that wrong. Do not cement the seal to the spacer. I guess I am only cementing the cork seal (that came with the bellows) to the actual bellows. Serviceman's reference also says to cement both sides of the fiber wear washer 7F5015.
