URGENT NEED FOR 1445 CHARGING VALVE

[MikeOConnor]

This seems to be the week for charging valves. I've got a new one for my 1850 that needs to be installed. Here's an installation trivia question -- does that rascal need to be bled after it's installed? I see a little tube-cap that looks a lot like the one that's used to bleed the hydraulic pump when changing the hydraulic filter on this thing. Just curious -- I'm waiting until Monday to call Terry and get the low-down.

I have changed mine twice and neither time was it required to be bled. not that this is right but Taswell never mentioned it. Do though installe the drain tube that they should be giving you.

Thanks! Good to know. Question about that drain tube. I just got the valve assembly (no drain tube) -- I guess I was assuming this was a "take all the stuff off the old gizmo and put it in the same places on the new gizmo" type project. Is the drain tube a "disposable" item that needs to be replaced each time?

On the charging valve, there was a nut that was "open" (had a hole in it) with a gold screen mesh in the head. PT made a change a few years ago and just routed that oil flow to a drain line elsewhere, instead of dripping into the tub. When I changed out my charging valve, Tazwell sent me an elbow and a hose, and I had to go get some other connectors as I chose to hook it to the drain out of the float mechanism.

This is a LOW priority mod. It may also have already been done.

Oh, and nice to see you again Mike. Its been a while.

Fascinating. How much oil dripped into the tub what that drain was open? I'm losing what I consider to be "a lot" (ie, a puddle on the garage floor every day), and "more than there used to be" (none). I assumed that it was seals (again). Last time, my local tractor-repair guys put new seals in (I'm not much with hydraulics) which is why this is my first time through. But maybe I'm fixing something that is actually normal behavior. I'll check with Terry tomorrow and see what the scoop is -- in the meantime, I'm off to do some mowing with a spare quart of 10w 40 in the backpack.

Ya -- the 1850 hasn't kicked up any puzzlers in a long time. Sorry to be gone so long. Thanks again.

Dear Mike,

If you didn't drain the brake line of oil, it doesn't need to be bled. The oil flow through it flushes almost all the air to the tank on the first power up. A few brake cycles will flush any remaining air out of the brake line.

If you did drain the brake lines, it would probably be advisable just to speed things up.

The installation is pretty easy. I do ~90% before bolting the charging valve to the tub and doing the final tightening (and strain relief) after it is bolted into the tub.

All the best,

Peter
