![]() I have been in the control valve and didn't see anything wrong. The only thing I have found at all is the tubes from the control valve to the manifold were somewhat loose, but not sure if they could be leaking. Will this spin it fast enough to get any pressure? Is it possible to lose pressure in the steering clutches and not gain oil level in the transmission? I was not losing any oil from the reverser or gaining any in the transmission. I thought about making a simple coupling to fit over a few of the shaft splines that will fit a 1/2 in drill. I thought I read some where that you could spin the pump with a drill, if I can find a chuck big enough to fit the shaft. I have other work to do on the machine that will take a while, but would like to know if it is going to work. After I get it all back together, is there a way to test the pressure before reinstalling. I was suprised at how little wear there was on the clutches and plates measured against new ones. I am waiting on some parts from Deere and will reassemble everything. I have the reverser apart and cannot find anything obvious that was causing the low pressure. All thats left bolted together is the tracks, trans and finals. Well, I got the ole girl down to the bone. It has a winch on it that I also plan to repair. ![]() I just use it around my place and have just bought a one man sawmill and will need it to skid logs. I have had the machine for about 12 years now and just want to get it back in good working order without spending a fortune. The previous owner did not mention anything about it anyways. ![]() I have had the engine out before and had it rebuilt, put a new transmission in it but I don't think the reverser has been into at this point. I know very little about these machines but have the manual and am very mechanically inclined. I thought it might be something in the control valve but I am not sure. All I have done to this point is checked pressures and relief valves. I have not blocked the oil to the steering cluthes or messed with the rate of shift screw. I used my foot to pull it out the rest of the way and it would barely pull then. Jdemaris, when it first lost power, I was running the machine and pushed in the clutch to shift from forward to reverse, when I released the clutch pedal, it felt like it stuck about halfway out. To make all "like new" you could spend many thousands of dollars. You could spend a small fortune if making all like new, considering all the isolator parts, front pump, input and output shafts that tend to have worn splines, etc. When it's your own machine, it's a different story. When a shop does a reverser and work has to be warranteed - parts that are 50% worn are not resused. In the control valve assembly itself, the shift-fork inside will need repair or replacement. Maybe some or all clutch discs, depending if they are burnt or warped. Pump gears and housing are easily checked just by appearance and feel. At the least, you're going to need new rubber seals, probably a new manfold and iron rings. Also depends on how perfect you want it, and how many useable but worn parts you are willing to use over again.īeing a C series, the seals will be rubber instead of steel except for the forward-reverse manifold. Some of this also depends on the vintage of your reverser and how many times it's been repaired before. generally speaking when a reverser is worn, all moving parts will have wear. Are you sure the clutch pedal linkage is returning fully, and did you try opening up the rate of shift screw? Also, have you tried blocking off the pressure line that goes to the steering clutches to see if then the reverser pressure goes up? My point being, how do you know you're not losing that oil pressure in the steering clutch packs?Īs far as rebuilding goes. Seems a bit unusual to get an even 70 PSI in forward and reverse at all RPMs. I have tried shimming the relief valves but that did not help. I have checked the pressure at the control valve and I am only getting about 70 psi in both forward and reverse. BSims66173 wrote:I have a JD 350C that has lost power.
