Re: 40c Roller interference

Bolts will work, only small issue is you will have a bolt head that you shoe can catch on, but that is very minor.

Re: 40c Roller interference

You can drill the holes in the clutch housings to 9/16 NF, and get the correct tapered nuts to put back on and that part will be fixed.

Re: JD 1010 1962 w/6 way blade

Last price I knew on the kits was a decade ago at least, and they were $1400 give or take. I fixed ours by brazing all the holes shut and rewelding, replacing any worn pins, new bushing around the T handle, and new thrust washer.

Re: 1959 440 dozer kicking out of 2nd gear

Tapered gears are heavy use and/or bad bearings. There are bearings inside of sone of the gears you can't see, and pieces won't fall out.

Re: 1959 440 dozer kicking out of 2nd gear

It is more than a lot of work unfortunately, remove everything attached to the transmission until all that is left is the transmission, then remove the transmission from the crawler, and then tear the transmission down. Its not rocket science, but not easy, and very time consuming. Will it keep runn...

Re: 1959 440 dozer kicking out of 2nd gear

Typically this is an indicator of bad bearings, tapered gears or both. Pull the top cover off of the trans and inspect the gears, check for play as much as is possible.

Re: JD350b Fuel and Clutch problems

No new fuel lines available, seals are an injector shop or Deere item, most likely Deere.
If the PTO spins, the steering clutches are the problem.

Unless you really need the disconnect for very cold weather, I wouldn't waste the money, it serves no other purpose.

Re: hey everyone, looking for some guidance

This is one of the main reasons I never reuse pressure plates, total PITA.
New ones on the shelf.

Re: John Deere 350 hydraulic system pressure relief valve o-rings sought

I have had pretty fair luck with Seafoam to get moisture out of hyd oil. Heat is also good, but you need the hyd oil hit for half an hour or so.

Re: John Deere 350 hydraulic system pressure relief valve o-rings sought

Jim is correct. You have an "open center" hyd system which means the oil is always circulating at volume, but no pressure other than inherent loss to friction inside of lines and hoses. No pressure is developed until a valve is pulled, and even then, the bypass is not open unless the pressure called...
