It has resulted in many seized engines.ģ50C used new style pistons seals, and clutch disks. Also use that God-awful spring-loaded 'Torsional Isolator' assembly for a drive that attached to the flyhweel.

Also used a special spring-loaded drive-disk that attached to the flywheel.ģ50 used a new style reverser pump and used a drive disk arrangement like the 1010.ģ50B used a new improved front input shaft with a larger center bearing which was a high failure area. The reversers from 1010s to 350Cs differed in at least these ways.ġ010 used a different input shaft and different front reverser pump. Thus the descriptive title of 'powershift.' Deere made 8 speed transmissions in wheel tractors named 'Powershit.' It was designed so you could reverse direction under full load/power. The 1010 was first the use what Deere called a 'powershift' type of hydraulically activated clutch pack (made by Twin Disc).

Just wasn't supposed to shifted under any kind of load. Since all gears were 'constant mesh', it could be shifted on the fly with no clash. To be technical, the two-cylinder 440 had a reverser that could be shifted 'on the fly.' It has two wet clutch packs, both with over-center clutches that were mechanically engage. How similar are the reversers in the 1010s and the 350s? I should have explained that first I suppose. I only mentioned them because I know they are out there. I stole his idea and converted a couple machines we had. Completely doing away with the need for a steering pump. When he did he installed the fitting in the side of the reverser valve body and updated his steering as well as getting his power assist back. His steering pump had went out and he had removed it. I've also ran into one that had been converted by the owner. For the most part all straight 350s will have the steering assist pump. I've only seen two and at first glance you would swear they were 350Bs. My guess would be right before the 350B was introduced. We're not supposed to know that and Deere denies ever having done it. Deere had a few of these 'Special Customers' that would try new things out in the real world before production ever came out. They were probably handled through 'Special Customers'. The straight 350s with this configuration would be really rare and very late straight 350s. I don't think I left any thing out but maybe some of these other guys can help with your answer. There are a few older machines, either with or without a reverser that will have a power steering pump mounted on the front of the engine that supplies the hydraulic pressure for the steering assist cylinders. On a few straight 350s and most 350B models, which have dry clutches, the reverser supplies hydraulic pressure to steering assist cylinders that help in steering effort at the levers.

On older dry clutch machines, there is a mechanical pressure plate that engages the clutch packs. The 350C and 350D have wet or oil bath clutches and brakes. The reverser used in the C and D models supply the hydraulic pressure needed to engage the clutch packs on these models. But, with a few minor modifications you can install one from a straight 350 into a 350C or a 350D. There are a few little things that are different from the Straight 350 through 350D models. The reverser is identical for the most part in any model that it is in.
