Hydraulic valve leak

rrlund · Mar 26, 2020

Yo MikeO-Wi,the weather warmed up enough for me to want to check out that valve leak this morning. I got up in front of the axle with the air nozzle and a light and found out where it was dripping. Turns out it was dripping from that o-ring elbow that goes in the front of the valve. There's a steel line off of it that goes up and around the back of the tractor.
Anyway,I tightened the nut on the elbow where it mates up to the valve and that fixed it. What a relief!

Behind that nut will be a washer covering an o-ring. Might not be a bad idea to put on the to-do list to replace that o-ring.

Ya,it just squashed the o-ring a little tighter. I hope I never have to replace it,I don't think it'll turn all the way around to get it out without taking the whole valve off and the cab frame looks like it's in the way of getting it off as one whole unit. The tractor's gone 51 years as is,maybe it'll go 50 more before it needs to have that replaced. LOL

We'll keep fingers crossed for ya.

I'm kinda tired of hydraulic stuff this week too. Had a hose blow on my mini excavator that runs from the right control handle down to the valve block in the body of the machine. About enough room for a midget to work in or be double jointed with really long arms.

Good to hear! It's quite a bit of work to get to the inside block and we really never had any problems with that. We are current working on one of 1855's without a cab and are replacing the old spools with rebuilt ones. We were also going to replace the hoses from the spools to outlets with new ones made up at the local parts store. Turns out the fittings going into the spool are a bit bigger making it difficult to install. We had to shave off part of one of the bolts on the rear axle housing. After it was installed, it was too tight against the housing that it would not allow us to correctly install the back hose. The threaded part of the fittings fits perfectly but the remaining parts are a size bigger. Not sure if anyone out there has dealt with this. I do have an email in Maibach to see what they have to say. In the worst case I have 4 useless hoses but in a better case the bigger ones will fit on the outside. Always something.
