Wondering if anyone knows how to remove a rounded lift valve / screw on Western Isarmatic IIIa (cable) pump?
The previous owner rounded out the hex head. I tried a hex key & wasn't aware the valve screw is actually plastic & I believe I've just made it worse.

I've owned it for two seasons and in prepping it for the upcoming season, I found an angle ram had leaked and drained all the fluid, so I replaced both lower rams with new, reassembled, filled & bled the system. Now the blade doesn't lift more than 6 inches (side rams work fine). I've also ordered a new lift valve & pump filter & gasket just in case.

Sounds like you will have to get a new cable assembly and the cut the old one and drill and tap it so you can put in a threaded bushing.

I could walk you thru how to remove the plastic lift valve if you would like to give me a call at the shop Tuesday or when you get a chance.

All parts are readily available.
I am surprised by that considering that most companies aren’t big on providing parts for things reaching 30-40 years old...
Then be surprised cuz he's right.

You can't buy mounts to install it on a new truck but beyond that most all the components are indeed available. Off hand, about the only item not available to my knowledge would be the entire power unit

It's fixed!!!

I spoke to John this morning for about an hour. Awesome guy, very friendly & knowledgeable!!:notworthy

We discussed many avenues of possible causes & remedies.... Probably the LAST CASE scenario would be removing the lift valve, which would have taken some drilling with a specific bit as to not damage the aluminum housing/casing and tapping / chasing the threads after removing the remnants of the plastic / nylon valve and installing the new one
- Not something a novice like myself really wanted to attempt anyway... :nope

Turns out I didn't need to remove or adjust the lift valve after all.

What I did was: (with the vehicle off) push down on the upper ram in the neutral position, unhook the chain, & loosened the packing nut a little on it)...I raised the ram without the chain to test it, shut it off & pushed the ram back down until it bottomed out & tightened the packing nut back up. I hooked the chain back up, (2 links lower than where it was) & started it back up... Works awesome now, with full lift!!

Many thanks to John for his time & advice, & to the rest of you guys for your suggestions & concern!!!

Happy Plowing! plowing! MIKE :drinkup

I am surprised. It is hard to find parts at times for things like a 145GZ...
