350 transmission noise?

Jerseymill · Post by **Jerseymill** » Fri Feb 12, 2016 6:04 pm

Just acquired a 350 crawler loader with Diesel engine and reverser. It has steering issues and runs rough, so I have some work to do. Now my question is when I start it a loud noise resembling a bad bearing or something loose comes from under the floor boards, as soon as I increase the throttle from an idle it goes away. I know it's not easy to diagnose from my description but I thought I would just throw it out there. Thanks

ITS your torsional isolator search isolator and you can read ALL about it .... May be nothing to worry about OR????

Without hearing it your correct - it's tough. JT Richards is probably correct on the isolator although most people call it a "rattle" not a bearing noise. floorboards come out easy, possibly get a better listen with them out. this site is the best for help.

I will second the isolator being the noise, rattle, loose type noise at idle then smooth's out as engine speed is increased.
engine needs to come out for replacement.
there is a new style isolator kit, pricey but much better than original style.

Yes it is a rattle noise

This is what the "RATTLER" style looks like --- if you are wondering.

Yes they work now, thanks. Is there any way to look inside the clutch without pulling the engine?

cantbeatadeere · Post by **cantbeatadeere** » Sat Feb 13, 2016 8:06 am

No, pulling the power unit out of these crawlers is very easy(at least on the dozer models) If you look at the side pic with the springs you can see what the rattle is --- the small fingers that stick out under each spring at the flywheel surface come in contact with the dowel pins an cause the noise....the latest version is a thick rubber isolator that flexes and is quiet / more durable.

Is the noise the result of a problem or is it normal? How much is it to upgrade to the new style?

Normal for that style, I converted mine because the springs are known to break and jam up the engine by wedging between the flywheel and reverser body....then it's a tow. I will bring my thread up from when I did mine and you can see how it's done....it was pricey, over 2 g's if memory serves.
