My 450B steering is not very good and the reservor for the power steering wont hold oil for very long. Also my 6 way blade control valve is leaking bad. Is there a rebuild kit or anything for these? Any help is greatly appreciated.

What did you end up doing? My 450B steers like shit and the power steering reservor wont hold oil for very long? I didn't even know it had power steering till a year ago.

ok thanks. Does it have a fill plug and a check level plug like a rear end then?

Are the final drives oil separate from the transmission oil? If it is can anyone tell me where I check, fill, drain and what type of oil it takes? Thanks

Thanks a lot Steve. I really appreciate your help. Never pulled a motor on a dozer so this could be a fun one.

yes its engine oil. it runs down behind the starter. The seam where the block meets the clutch housing. So i must have to pull the motor to replace o-ring?

My 450B is leaking oil. A lot of oil by where the block of the motor bolts up to the bell housing or whatever that's called. Back end of motor block behind starter. I was thinking maybe rear main seal but a guy that works on a lot of tractors said if it was a rear main even if the seal was worn real...
