![]() Sorry for your dilemma, lets take this in steps. Still, the snapped reverser countershaft has me thinking something else may have happened inside the trans. So, they would both be disengaged at this point and so the trans input shaft would turn. This machine has Wet steering clutches which need hydraulic pressure from the reverser pump to engage. They would be engaged always, running or not. The most fun part of crawlers is they started with the trans and bolted everything else to it in both directions.Įdit: I was thinking Dry steering clutches. There is no differential, just a spool on the ring gear back there. The steering clutches are always made up until released by the steering levers. I bet some bearing bits jammed some teeth and then things got Fast 'n' Ugly. Sounds like you have a trans issue that busted more than the reverser. If you have it in any gear, the input shaft won't move by hand. There is Torsional Isolator at the flywheel to absorb torque load peaks. So, the reverser clutch packs act as the master engine clutch. The clutch pedal operates a dump valve for the reverser hydraulic pressure. You need the 120 PSI or neither clutch pack will make up. The hydraulics to operate the reverser are internal via a small pump on the spyder shaft. In Reverse, the straight thru shaft is the one idling. The counter shaft is always rotating, but does nothing power flow wise until the Forward clutch is disengaged and the Reverse clutch is made up (again by hydraulic pressure). Power flow is thru the Spider shaft (input) of the reverser and straight thru the center when the Forward clutch is made up by hydraulic pressure. I would really love to speak on the phone with someone who has knowledge of the power flow. When the reverser is out of the tractor and the transmission is in gear should I be able to turn the imput shaft of the transmission and the tracks not move? Or if something is broken in the final drive. Im trying to figure out where the pressure drop is It need 100 to 120 psi to engage the clutches and move ?ĭoes the steering clutches also need 100 to 120 psi for the tractor to move. The reverser has about 30 psi of pressure. We reassemble the machine and it still wont move. The counter shaft was twisted in 2 at the front bearing. We disassembled tractor and removed the reverser. He told me he had been adding reverser fluid about every 10 to 12 hrs. It was working fine and He was grading some gravel and heard a load pop and the loader stopped moving in it tracks. lb) at 1,300 rpmįorward: 10.5 kmh (6.5 mph) Reverse: 3.1 (1.9 mph)įorward: 10.5 kmh (6.5 mph) Reverse: 10.5 (6.My son in-law has 1980 350 c crawler that wont move no forward or reverse.John Deere 350 Specifications General Specificationsġ49.2 N Front-mount John Deere 6310: 2,360 mm (93 inch) blade.Front-mount John Deere 6305: 2,030 mm (80 inch) blade.Front-mount John Deere 6300 90: 2,280 mm (90 inch) blade.Front-mount John Deere 6300 72: 1,820 mm (72 inch) blade.gal) fuel tank.įollowing attachments are available for the John Deere 350 industrial crawler: ![]() The JD 350 dozer is equipped with a clutch-brake steering system, contracting band brakes, open operator station, and 83.3 liters (22 US gal.
