Evening

Did you get the link I text you to cat info? I just been on it and it has all the service info on there for the TH220B.

I think I did hear something about early TH330's that had some sort of modification the solenoids or something on the main spool block which costs thousands, think cat did loads under warranty etc but some will have escaped no doubt and they wont want to know now I'm sure.

With out cat equipment to plug in you may struggle with it I think, but that link will help no end I'm sure.

On the th360's there was a pilot solenoid that used to fail not sure if its the same on the 220. The valve mentioned above was the PHS valve and was replaced with a simpler solenoid type it was mainly moisture ingress that killed them

 

[matbro man]

I am getting no power to the pilot solenoid and the warning light is on and flashing on the dash

 

[Vincent]

Do they still have the switch that knocks out the hyd functions in the cab. But looks like you will need to plug in ET

Looking at the info on the link I sent you now. It shows a rocker switch to turn off joystick controls should be the one closes to the rear window. don't know if that's the switch that operates the solenoid valve you are talking about worth investigating.

Looks like there is a fuse for the solenoid too possibly

Fuse number 9 for the joystick and number 12 for the PSH circuit

Got on the link dose the switch on the bottom of the joystick meant to move or if it was stuck in what would happen?

Sorry I dont have that link anymore. It was on an old laptop and the hard drive failed so I lost alot of info? have tried looking since for it and cant find it anywhere!

I dont think cat/jlg knew it was open to public viewing imo cause there was lots of info on there only dealers normally see.
Was possibly an old site they used and then moved on to a new site/system and left the back door open!??
