Brake adjustment 450C
I need help , New to dozers . Steering on this dozer was getting sluggish so I thought I would adjust the steering brakes. Pulled the plugs on both sides and turned the adjusting wheel to tighten brakes. Now it doesn't want to steer at all ?

Hydraulic control valve on 450 C
I have another question for all you experts. I have a 1979 450C dozer and trying to get used to it. According to the operator manual this 6way blade is supposed to have a float position if you push the lever all the way forward and stay there until you pull it back. Mine doesn't do this, is there an...

Leaky fuel injector pump
Has anyone had any experience with fuel leaking around the throttle shaft on the injector pump on a 450 C ? The parts book shows some packing. The shaft seems to have a little play in it. Has anyone tried replacing these packing washers ? I've never had one of these injector pumps off before -- majo...

Re: Clutch on JD450C
If I'm reading the responses from you people that obviously know more than me correctly , it sounds like I may have a stuck clutch. If so , how can I "unstick" it ???? The dozer had sat for awhile before I purchased it . How long I don't know!

Re: Clutch on JD450C
Thanks for all the ideas , in answer to first response - yes the dozer stops when I push in the clutch.I can't shift 1-4 gears while engine is running , it just grinds gears. I have to shut off engine to select gears.

Clutch on JD450C
I'm new to the wonderful world of crawler dozers so try to bear with me if I ask stupid questions. My problem : I recently bought a 450C and its in pretty decent shape I believe , pulls well in all 4 gears , shifts OK in shuttle. The problem is that the clutch disengages the drive but I can't shift ...
