PT&T Question

Re: PT&T Question

Never saw that behavior. Did you bleed the system? Are you using ATF or 5W-30 motor oil in the PTT?

Re: PT&T Question

Bled it, yes and 10-W 30 oil.

Re: PT&T Question

Just to be clear, you opened the bleed screws on each cylinder, while the bleed ports were facing up and run the pump to force the air out? Only the pump resevoir is self bleeding.

Re: PT&T Question

Yes Chris I did. there were little spats of air, and there there were none. I did it probably 3 times each between pump cycles.

Re: PT&T Question

Well. I guess it is time for a component test. Remove a small hose from the control valve and run the ptt motor. You should see a steady stream of oil shoot out. If so, maybe there is an internal issue with the trim cylinder. If not, maybe the pump or control valve is bad. Second test calls for removing the control valve and testing the pump.

Re: PT&T Question

Hmmmm OK I'll try the two small hoses individually and see how things go! Thanks!

Re: PT&T Question

OK so I got this sucker working, but I need to replace one seal in one of the rams, and the hoses are sweating for sure. I've checked around and they're still available, to the tune of about $320.00CAD!! Does anyone have any tips for less costly alternatives? Seems the fittings these use are quite uncommon??

Note: I did not bleed the system near enough for my first go at it. I drained the entire system and put about double what came out, back in, before it worked properly.

Re: PT&T Question

There should be a hose shop somewhere. They can fix them.

Re: PT&T Question

Keep your eyes on ebay for replacement hoses. I managed to find a brand new set of four and few years ago for $80.

Take the old hoses to a hydraulics shop and see if they recognize the fittings. The hose is easy to replace, the fittings are unique. Note how they are formed/curved to fit around the hardware.

Yeah I was to a half a dozen local shops yesterday, and none of them had anything like the fittings. Interestingly none of them mentioned "fixing" them either. Wouldn't guess that's possible?? I reckon I'd have to add the curves myself.

Re: PT&T Question

I've got a complete set of those weeping hoses that I kept when I bought the new ones. Keeping them just in case they can be repaired. I frequently deal with a very good hydraulics shop thru work and I'll try and remember to ask him it the hoses can be repaired.

Oh yes please MB, that'd be appreciated. I have read some about using hydraulic crimp rings and re-using the old ends, but that seems to get mixed reviews.

Re: PT&T Question

I just got off the phone with a local shop here that does custom stuff and has been recommended and told them what you had. I asked whether or not they could be repaired. He said in most cases the hoses could be repaired. Sounds like some of the problem may not be the hose as much as it is the fitting. His statement was "oh, those are stainless steel fittings".

Re: PT&T Question

I had a local NAPA make some up for me. The ends weren't bent quite right, but I did get them to fit with a little extra bending on my part. They charged me $15 USD(in 2002) each for mine, but they are braided stainless!

Re: PT&T Question

Those hoses have the same fittings as brake lines.you can bend them to shape.hose is tricky.braided brake line will work,but its costly.hydraulic fittings need some twitching and customizing .

Finally had a chance to talk with the tech guy at the hydraulics shop and he did say that the old hoses are repairable. He cuts the S/S tubing ends off flush at the old crimp then installs new hose and a type of high pressure compression fitting over the salvaged S/S ends.

This is possibly the same procedure that you had read about but this guy claims it to be 100% reliable. He is extremely knowledgable and I trust his opinion completely.

Re: PT&T Question

I Have old hose fittings welded to new hose.works perfect on the bench,I have not tested them on the water yet. the new sleeves need some rounding up,just to round them up.time will show under operating conditions if it will hold on.

I looked into this. The local I spoke to here voiced some concerns about using "crimp ring" style fittings to attach the originals to hoses, stating that the fittings once the original outer sheaths were removed, had nothing on the inner hose surfaces to bite into the hoses, and felt the new crimp rings, since they're not attached to the rest of the fittings, would provide marginal hold. He called (oddly enough) a competitor of his in Halifax, who seemed to confirm that opinion.

I went to the local dealer and asked them to sharpen their pencils. They came back to me with a price of $214.00 $CDN for the whole set, so I figured I'm this far in, I might as well finish the job. I ordered them, and now I await.

Got the new hoseds today, installed today she's all working - case closed.

Many thanks to all once again!!

Re: PT&T Question

I have that system too and to prevent sun/exposure damage I put the lines into that water pipe foam wrap; they should last forever!
