4200 hydraulic issues

[whynot162]

is there a link to a manual that shows how to work on the rockshaft? and adjust or repair this part that is sticking? Looking at the few parts I found on Ebay, they do not look like the valve on the tractor, so I am assuming that it comes apart to come off?

Have you looked up this tractor on jdparts.com to see the various parts and their assembly schematics?

Nother from manual. May/may not help???

This is a post that I had in 2009. It was a o-ring and fixed my problem. Hopes this helps

Thank you for all of the help, We replaced the shear pin and it works well now. Also soaked the area with pb blaster several times and it worked in and things are moving smooth. total cost of the repair, JD quoted $1500. he spent 0.20 on the shear pin, and about $5.00 on a can of PB blaster.
