610 tilt valve spool

[Tjones]

Hi, new to forum. I have a 610 and I am looking for a spool for the tilt valve. Mine is corroded at the foot control end in the seal area. Thanks for the addition to the forum. Tom

That spool is no longer available. I know a couple of people have even tried to source it through Parker (Gresen) with no luck. A couple of friends have had them turned by machinist…..(expensive) and I believe it was member Alchemysa that did his own repair with 'JB Weld' with good success. I'm sure he will stop by and describe his experience.

I can't help with where to get a spool. Actually I doubt they are available anymore but member 6brnorma will probably know.
You may have to repair it. You can get that done professionally, but I did it on the cheap. The 2 on left were repaired with plumbers solder. The one on the right was nickel plated over the pitted area. They are all smoother than they look.
By the way, if you replace the seals you must use the correct Quad (X profile) seals.

I do have the correct quad seals they are still available. I will try soft soldering. My spool looks like the one on the right, no grooves. Thanks Tom

Successfully soldering the spool took some practice. I used a cheap gas torch and a plumbers solder kit. The main thing is that you must heat the spool sufficiently to melt the solder on contact. Then you immediately flatten the solder with a hot knife. It looks a mess but cleans up nicely with a fine flat file. I still had a couple of very small pinholes near the edge of the solder but I filled these with some Permatex. (like JB weld).
Before I started I also cleaned out the corrosion pretty deeply with a dremel. Before settling on the solder method I tried filling the holes with Permatex but I wasn't satisfied that the bond was strong enough.
The right hand spool you pointed out in the pic above required a different approach. It wasn't deeply pitted. It just had surface corrosion in the chrome. I was not able to solder it to my satisfaction so I took it to a metal plater who masked off the tip and dipped it in zinc.

I tried silver solder, so far so good no leaks yet. Thanks, Tom

Good deal…..did you enlarge the holes to get a better bite? Also….just curious….did you use the U-cup seals or the X o-ring seals?

I cleaned the area on a wire wheel used Stay Clean flux with Stay Brite silver bearing solder. Chucked up the spool in a lathe and polished. For seals I bought them at the local Bobcat dealer, Quad seals. Tom
