#John deere 350 dozer master engine clutch series
Some early 350s use a spring-dampened drive-disk that can break, and 350s also sometimes lose the splines on the reverser output shaft and transmission input shaft - but those sorts of maladys are usually a "go" or "no go" situation, and not slipping.NOS John Deere Drive Clutch Thrust Bearing JD8841 170 220 200 215 24 222 218 213Ģ20 - COMBINE, PLATFORM (FLEX CUTTERBAR/RIGID)Ģ00 Series (200,213,215,216,218,220,222,224,230) Combine Cutting Platforms - PC1558Ģ15 - COMBINE, PLATFORM (FLEX CUTTERBAR/RIGID)Ģ24 - COMBINE, PLATFORM (FLEX CUTTERBAR/RIGID)Ģ22 - COMBINE, PLATFORM (FLEX CUTTERBAR/RIGID)Ģ18 - COMBINE, PLATFORM (FLEX CUTTERBAR/RIGID)Ģ13 - COMBINE, PLATFORM (FLEX CUTTERBAR/RIGID)Ģ16 - COMBINE, PLATFORM (FLEX CUTTERBAR/RIGID)Ģ30 - COMBINE, PLATFORM (FLEX CUTTERBAR/RIGID)Ģ00 - COMBINE, PLATFORM (FLEX CUTTERBAR/RIGID)ģ50B and 350B (Tractor only) Crawler Tractor - PC1169ģ50D Crawler Bulldozer and 355D Crawler Loader - PC2089Ĥ - HARVESTER, ENSILAGE AND FORAGE (ATTACHMENTS)Ĥ40C Log Skidder and Grapple Log Skidder - PC1523Ĥ40D Log Skidder and 448D Grapple Log Skidder - PC1887Ĥ50 Crawler Tractor (with 3320 or 3325 Winch) - PC922ĥ40B Log Skidder and Grapple Log Skidder - PC1524ĥ40D Log Skidder and 548D Grapple Log Skidder - PC1977Ħ40 Log Skidder and Grapple Log Skidder - PC1518Ħ40D Log Skidder and 648D Grapple Log Skidder - PC1978ħ70 and 770 (Automatic Blade Control System) Motor Graders - PC1504ħ70A/770AH and 772A/772AH (Automatic Blade Control System) Mo tor Graders - PC1621 If the ring-gear is still moving, then you know for sure that the steering clutches are slipping. It's unlikely that your reverser is slipping -but you can check by looking at your ring-gear when the machines stops. Reverser can use any good combination hydraulic/transmission oil.
One is for lube/release pressure - should be around 20-30 PSI all the time, and the other is main clutch pressure - 120 PSI and up. There are two test ports with 1/8" plugs on top of the control valve. When the 350C series came out - with hydraulic steering clutches for the first time - the reverser pressure was jacked up to 150 PSI since the same oil that runs the reverser clutches also runs the steering clutches - and the steering clutches will slip at 120 PSI. A grease-gun hose attached to a gauge will work fine (with 1/8" male pipe thread. The clutch pressure should be at least 120 PSI with a dry-steering clutch machine. was handing out for awhile to shop grease-monkeys who suceeded in fixing a problem that their field engineers had not yet figured out. In case you're wondering, that's a bogus little award Deere Co. In fact, Deere Company - from our Syracuse headquarters gave me the "Golden Belt-Buckle" award at the time for fixing a few of them. I cannot remember if we shortened it by a few threads, or lenghtened it - but I'm pretty sure we shortened it. It's a threaded bolt and nut and determines the length of stroke of the accumulator piston travel. Ended up we fixed many of them by changing the length of the stop-bolt inside the shift accumlator. As standard procedure, we'd increase the rate-of-shift to a point where a full-throttle forward-to-reverse shift could almost break your neck. We tore several down and could see nothing wrong with them. We also had what seemed to be the same problem with MANY 350Cs when they were brand-new. It often appeared to be caused by every sealing area being generally worn out. I can say that we had similar "sticking" problems in the older 1010 and early 350 reversers with metal rings, and also in the later or updated reversers with mostly rubber rings.
Can't say I've ever been inside a reverser when it was running to witness the problem, however. We had suspicions along the same line whenever we got a reverser with the problem as you describe it.
