koboma :

570 Skid steer??

koboma :

# XXXXX is solenoid valve that has to open for the boom to work.

koboma :

Is it getting power?

<span class="JA_chatAuthorName"Customer:

Yes. The boom "jerks" when pedal is pushed.

koboma :

Sounds like solenoid valve is not staying open.

koboma :

It has to stay open to keep boom moving.

<span class="JA_chatAuthorName"Customer:

o.k. should I take it to a dealer?

koboma :

That would be your call. You might remove the assembly and see if you see any debris or bad o'rings/

<span class="JA_chatAuthorName"Customer:

o.k. Thanks.

koboma :

Thank you.
