450b high range

Post by rock digger » Fri May 16, 2014 8:56 pm

I have checked the pressures ans all seem to be in order except whenI shift into high range. Reverse and low are fine and hold enough push and pull hard. When shifted to high it will move then slow down and stop. I have been running with the gauge in the pressure port and it seems to vary fron 40 to 100 back and forth. When in high range.

I have been working on adjusting the clutch and probabley need to fine tune.????

My presure at start up is about 180-185 and will stay there even after an hour of running I only lose in high range. Any Ideas????

Was digging some basswood stumps tonight still foze under some of them.will spring ever come? Thanks

sounds like seals in your high clutch pack time for a rebuild..... if you keep running it DO NOT use high or you WILL fry the clutch pack if it is not gone yet

Thanks Jt
I have been running it in low range so far was afraid I might screw it up to use high. Is it a big job to do these seals you talk of? I will be doing some more testing today. THanks
