I should of mentioned that my dozer is also a 450B, 1973 according to the serial number and it also has a turbo. Also, the loctite was used to secure the threaded inserts once they were installed, extra insurance.

Update on clutch housing bolts. After an enormas amount of help from pdmech08, I had a machine shop install locking threaded inserts on both sides of the clutch housing with 277 loctite. In addition I also found a small crack in the right side frame, it had just started to round the corner and migra...

Looks like the drain hole in the bottom of my clutch housing,(450B) it has a cotter pin in it like that. If you have hygard leaking out of it, you may have a problem with your transmission pump leaking. Digger

Well, engine out, right side frame good, no broken bell housing case, transmission case o.k. Three of the right side frame bolts to final drive housing missing and the fourth loose. The question today, is it possible to use a 1 inch reemer from inside the bell housing and install the threaded lockin...

Great picture, keep em coming as you progress. I'm intrested as I'm going to do the same thing.

Thanks guys for the feed back. Snow banks are finally going down and its time to start working on my "in good condition johnny, according to the dealer " before I can use it. Going to start removing sheet metal, rad., engine, and clutch housing so I can fix the broken side frame bolts. Hope there's ...

Does anyone know if I can use general purpose hydrulic oil in the transmission or do I have to use the JD type 303 special purpose oil? thanks for any help.

Great, thanks Steve, I'll check with Lavoy if I need them. Digger

Sorry about the multiple posting, every time I previewed it gave me a error code.

I really appreciate all of the replies. Another question, if I fine the side frame cracked other than along the weld where it attaches to the final drive, is it repairable by welding or is it like a bridge I beam where any welding along the web weakens it? Digger

Thanks for the replys Randy and Steve. I just bought the machine and when I found this site started to relize that I had to look alittle closer at what I bought. I was told that it was in pretty good shape. Oh well, buyer beware. Anyway looks like I have some work to do before I dare use it. Hope th...

I'm new to the site and it seems like you guys are willing to help if you can. My question is the right side frame bolts to the bell housing are either broke or stripped, but can not be tighten. If broke any ideas on how to get the remaining stud out? If bell housing stripped would helicoil work? I'...
