Hi , got a 2010 terex pt50 which has the same hydraulic drive motors as the cat 247b (rexroth 427/620s motor) , mine started leaking by the outside flange where u can see its darker in attached pic ,where the squirrel cage for driving the track bolts on, all the hydro oil was gone fast. Pulled drive all hoses are fine as are fittings,, we pulled the drive partway apart and I found cat sells a seal kit for this motor but it states this in ad " This seal kit does NOT include the distributor housing seals or the distributor seals" , I think it is the seal that is below this bearing in second pic. So my question is , is that the distributor seal.. also does anyone know where one might aquire the internal schematics diagram of this motor or service manual..... , thanks
What is the Cat Part Number of either the motor or the seal kit..?
hi Nige, the part number it shows me is CT149807 , found here > http://www.loaderpartssource.com/ca...ompact-track-loader-drive-motor-seal-kit.html , what in your opinion could of caused this failure ??
cat motor part # 222-5662
Unfortunately the Cat parts system does not show the distributor seals. What is even more suspicious is that the Disassembly & Assembly procedure for that particular Part Number of motor states "The following procedure is intended for cleaning purposes only." - that leads me to believe that they expect the internals of the motor to be unrepairable if anything major goes t1ts up ...... The only thing I can suggest is to get the o-rings out of the distributor and try to match them up somehow. If you want the D&A procedure for the motor then drop me a PM with your email address.
we took it apart more and the outer bearing and seals are fubared, the axle should clean up, but the seal retainer on outer housing is chewed up fairly good,, if you could send me the D&A procedure that would be awesome sended you a pm with E address , thankyou
