Ok, I understand the 3/8 ball bearing apart. I’m going to have to pull the idler back with a come along. Hoping I can use a come along to pull the track back over top of the idler. The under carriage is only a few years old and in great shape. What I did find was there is a big nut centered on the o...

How do you prevent loosing the ball bearing under the fitting. There is a grease blender besides the grease fitting to release idler tension as you stated. Is the bearing unde there or the grease fitting ?

I have a straight JD 450 loader. On my property, my right hand track came off the front idler. What is my best option to get it back on ? Should I remove a pad and look to break the chain ? How do i seperate the chain ? I believe some tracks have a pin that can be removed ? Is it only one master pin...

New John Deere 450 loader owner here. It’s a straight 450 diesel. I’m just learning about this machine as I only purchased it a few days ago. I have a service manual and Im just now surfing through it. I busted a hydraulic hose for the front loader bucket. Small leak for now. I don’t intend to use i...
