I have a Mitsubishi bd2g2 dozer.
I am trying to replace the leaking seals in the right side Steering Clutch Cylinder Assembly(SCCA). This SCCA is a hydraulic cylinder which pushes the shifter 3-fork ring against the clutch to allow the clutch to slip and the dozer to turn. I have removed the Clutch/Brake Pack successfully with heat and penetrating oil. I have been trying to remove the Steering Clutch Flange from the drive shaft in order to remove the SCCA. This is the 妬nboard flange not to be confused with the trackside flange. I have removed a bolt, heavy washer and sheetmetal bolt locker from the drive shaft. I have put much heat on the flange with an oxy-acet torch. I have modified a gear puller to attach to the flange and forced it against the splined drive shaft. I have put much force to this puller with no bending of the puller. The flange has NOT released from the splined shaft.
Question 1. I do need to remove flange to change SCCA seals, right?
Q2. I am pushing against the center of axle bolt, WITHOUT the heavy washer in place. The flange doesn稚 budge. How much push with 24" breaker bar befor damage?
Q3. How much heat can be put on flange before that heat travels back to bearing and causes damage?
Q4. Should I rig it use the SCCA to push out the flange? It is hard to imagine that the SCCA would apply more force than the puller did.
Q4. Where would you suggest I buy seals and clutch disks?
I'm stuck, the dozer stuck, what would you do?
Thanks,
