My 1975 350B with 6 way is getting tired and I am getting tired of spending 8 -16 hours maintenance for every hour of work it gives me. More disturbing is the additional 4 hours of internet research I spend every time looking to replace an "obsolete" part. JD has a standing policy of discontinuing a...

I have checked the clutch linkage and it seems to be returning to engagement position just fine. Return spring is strong. Since this problem started rather suddenly, I doubt there is a problem with the clutches, pump or relief adjustments. I am wondering if a piece of dirt could have got lodged in o...

Been there, fixed that - just yesterday (I think). The problem is the old L shaped link with the ball and socket (PN AT17364) has a different thread pitch (smaller, machine thread I think) on the adjuster rod than the part they want to give you to replace it (AT317916, I'm guessing). The new part ha...

JD 350B crawler with reverser. Used it for about 20 hours since I got it. Just started having problems with power to the tracks - forward & reverse. wouldn't pull itself uphill. Higher rpms didn't help. Slowed to idle and crippled back to the shop. dropped pan and pulled reverser filter. Filthy, as ...

Ok, I just noticed someone with a JD 555 has a similar Roosa Master IP leak problem. Leonard responded that seals around the metering shaft can be replaced - but you should have a tech manual. I do (though I haven't found it to be much help). I'm thinking if the shaft is worn, then likely other comp...

I have posted before about problems with my 350 B running rough and smoking. I have changed the fuel filter and drained the tank sump, with no change in behavior. One thing I have noticed is a significant steady drip from the injection pump coming from the fuel metering shaft where it sticks out the...

JD 350B crawler dozer, Kentucky. Does anyone have the specs for the rail links on a JD 350B - showing range of link height and distance between pins? all the old web links (crawler forum, tractor parts - now General gear) no longer have this information posted. Service manual is no help. I hate to h...

THANKS FOR ADVICE, FOLKS.. iNJECTORS ARE COMING OUT AS SOON AS I GET BACK TO WORK ON IT. wIL LET YOU KNOW RESLTS.

I know nothing about your particular machine (I own a 350B and an IH 500E), but your early comment on frothy fluid stuck in my mind. Is it still doing that despite added fluid? Frothy generally = air leak (on suction side). Milky, OTOH, = water in oil. My old 500 has a large rubber hose that draws f...

I never heard back from anyone but maybe I didn't provide enough detail. My 350b (3 cyl diesel) runs "rough at lower RPM (1000 & below) like a gasoline engine that has a faulty carb float and letting too much gas in. Never heard a diesel do that. At higher RPM, it smooths out, but emits more than no...

New owner of a 350b with 6 way, & winch. Starts and runs good with good oil pressure. Previously on a farm, so not a great deal of use - overall not worn bad at all. Original tracks and undercarriage. Don't know hours (Meter broke). The only issue I see (other than a broken winch control cable), it ...
