    My first plow truck, have a broken packing nut on angle cylinder. Any qiuck easy place for parts?
    Also E47 won't stay raised, drifts down quickly. No leaks around lift cylinder or vent. I'm assuming something with the solenoid valve?
    Repair manuals would be nice to have too if anybody has some for sale?
    Thanks, Dennis........

    Here's where you can get the packing nut Dennis..CPW Just click on the number to bring up the part you need.

    The leaking lift cylinder problem can be due to a few things but usually it is due to a defective/dirty "A" valve like you mentioned (or a cut O-ring on the A valve)....but a worn packing cup on the lift ram will also cause it..

    CPW looks great.
    If the lift cylinder by-passes the oil must go back into reservoir? That would explain how it could by-pass and not show a leak?
    Thanks, Dennis....
