Looking for instructions on how to remove and replace HWH solenoid valve

Anyone have instructions on how to remove and replace the solenoid valve in a HWH leveling system (325 I think but it might not make any difference)

I think all you need to do is remove the cable and then just turn it,
lefty loosy. Some oil will run out,put a big pan under it.

Thanks for the quick response and the information.

I don't think I can fit much of a pan under so hopefully it won't make too much of a mess!

I know that when I replaced the HWH solenoid on my system, I just unplugged the solenoid and unscrewed it by hand. Very little to no fluid came out. The new solenoid was a little harder to put back in because of the new seals. I put a little of the hydraulic jack fluid on them and then had to use some channel lock plyers with plastic jaws to turn it all the way in. Be sure to get it completely seated in the block before testing. Good luck.

Thanks again for all the responses.

As Siggy and Thor3650 said, all that was needed was to turn it CCW until it came out. In my case very little fluid came out and then spin the new one CW.

Unscrewing / screwing back it wasn't that easy since the one I was replacing was in the centre and I didn't really want to take out the other ones but overall it was an easy fix and $145 later and maybe 30 minutes of labour and my jacks are working properly again !!! (It will certainly beat placing axle stands under the frame every time I levelled).

Thanks again. Wouldn't have tried it without the forum.
