JDcrawlers Messageboard

I checked with RDO Equipment but they said NA. I check with JD and see if they have Thanks Jim. She is finally up and running but has a slight seep. one gallon per year or two kind of seep. not Real concerned but would like it right.

anyone have a idea where I can find a seal kit and or replacement valves for my 450c. Seal kit # is AU40434 or the valve assembly AT43378. Not finding these numbers anywhere online. It's not an emergency just some seepage I wanted to stop.

I finally got the parts that I needed for the right side steering clutch and brake. Had to get a used hub and manifold ring. The manifold ring has a threaded hole and a small hose on it going to something. Mine had the threaded hole but no hose. the hole for the hose IS EXACTLY like my old manifold ...

finally got the correct parts after five weeks. when the shaft broke it messed up the inside of the steering clutch hub. supposedly the 450d hub and manifold are replacement for the 450c but they are Different. Yes it would Probably work BUT it doesn't have the seals like the 450c so I waited for th...

Went through the same problems and did the complete clutch and hlr adjustments and Check the fluid in trans NOT running. Follow the manual step for step. Worked for me after the third time because I did not follow step for step

After tearing everything down the Threaded Does not require a plug , it is only there to release any pressure that get past the sealing rings. the ring manifold had a crack in it from someone over tightening the elbow for the pressure hose sometime in the past. I was able to find used parts since th...

Just incase anyone is interested there was catastrophic failure in that the drive shaft twisted in two. I have a shaft coming steering clutch housing on the way and pressure manifold. all new seals and sealing rings and several cases of beer :lol: :lol: :lol: . so glad its just nuts and bolts. Yes t...

put a 1/8 pipe plug in the open hole and no more air leak. Did not find a cap screw and nut like the parts manual shows. going to replace hose and fire off and check track movement. Next step is to drain steering clutch housing and clean out to see if there is really any catastrophic failure or not.

pulled the left steering clutch cover , disconnected hose air checked the manifold and it held pressure. left clutch manifold is Not drilled and tapped for a plug like the right side. Has anyone seen this before?? The disturbing thing to me is the pieces in the bottom of the steering clutch housing.

I will be pulling the cover off the left steering clutch housing to check the left side clutch manifold and see if it has a plug or not. I used a magnet to check around in the clutch housing just to see if the plug was n the bottom. I did not find a plug BUT i found several pieces that I think might...

Well I wasn't smart enough to check oil pressure before going in the steering clutch housing. I pulled every thing off and opened it up and the Hose is Not blown. I removed the hose from the upper fitting and air checked the hose and have air blowing out of a hole in the clutch pressure manifold. it...

thank you. will keep posted as work progresses

Sorry Steering clutches not (final drive)

have not had a chance to check any pressures or try to follow the flow charts, but I have a question. With the engine running in neutral is there still pressure to the clutches and if so if I removed the brake adjusting plug would I be able to see oil spraying if the hose is ruptured. I'm just tryin...

I sent this post before but something didn't go through..... I keep forgetting people can't read my mind. :oops: Yes it is a 450CA . A true C with wet clutches. Track Loader A. I was hoping it would be simple but Nothing is easy in my world :P . This unit has the extra framework because it also is s...
