79 JD 450c track tensioner adjustment?

[450cgreenhorn]

How do you adjust tracks on this machine? also I lost right steering control and believe linkage came apart under the seat/gas tank area how do I access linkage area to check? Everythings looks right and together all the way back to the fuel tank....tips, tricks, Pics????

Do you have any of the manuals yet?

With mine the seat bottom removes so I can get to the steering linkage and check the transmission oil level.

[450cgreenhorn]

no manuals yet. I know....get one right

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.

thanks for the advice. yes it was all of a sudden. just no right stick control. I think its a 79 450c. is it hard to change the hose?

you adjust the tracks by pumping grease in the fitting on the arm right behind the front idler

thanks for the info ib4hoyt...also I just ordered a manual on ebay. should be here in a week....then i wont sound like a tard. lol

[450cgreenhorn]

well guys, I bought a manual, adjusted the tracks and popped the seat up and off to check out steering linkage(s)....well simple fix, $2 roll pin broke in the right steering brake pivot linkage, little bit of a pain to get to but we got'er. thanks for the guidance....
