Hey there 450cgreenhorn, have you looked at the linkage that connects to the steering valve under the seat cushion? Did it stop turning to the right all of a sudden? Our 1977 450c stopped turning to the right also. when I opened the left steering housing inspection plug I got oil coming out and I can hear oil spraying. I think I have a hole in the pressure hose that delivers oil from the steering valve to the clutch pack. I only have this symptom in the left steering housing. The right is good. I will have to take the battery box, fuel tank, seat frame and hydraulic tank off to get access to the steering housing top covers. I know I don't have to take the hydraulic tank off for the left side, but I think I'm going to inspect the right hose anyway. What year is your 450c. My Technical manual number is TM1102. Check your year and model before ordering. I paid like $99 for a downloadable copy from johndeere.com.
