Help finding Lift valve part? GT14 Repair?

[Machria 77]

My lift valve part #8363 on my GT14 is leaking out the top (see picture). Anyone know where I can get a replacement, OR can it be repaired?

Thanks...

Yes it can be repaired. The square section o ring seals can be removed and replaced. I overhauled mine last year...

[Machria 77]

Awesome, thanks. Where do I get the seal? Any special tools needed or just plain jane take it apart, put on seal and screw back together.... ?

I'm in the uk, so just went to a bearing/seals supplier and they had them in stock.

The spool comes out by undoing the lock nut and screw at the bottom. Take care not to lose the float detent spring!

Thanks, you sure it was the same 8363 lift valve? I just found an O-ring kit for a lift vavle for WH, but it said it does not fit this "one piece lift valve".

yours looks like mine, a one piece casting with 4 ports in a diamond formation

[Machria 77]

Great, thanks.

So is there an O ring kit for this valve?

[meadowfield 2,595]

Can't help you I'm afraid... The parts are available in the uk, therefore they are fairly standard

Where they called "Wheelhorse O Ring Kit" when you got them, or where they just o-rings that matched and fit?    Trying to figure out what I should be looking for.   thanks.

I just took the old ones into a bearing shop, they measured them and got me some in after a couple of days.

I haven't opened my valve up yet, but,  WH didn't make them they bought them.  I would assume the O rings are a standard size.  You could measure them and buy replacements at a good hardware store.  Or look in the yellow pages for hydraulic service places.  Just take your valve assembly in I am sure they can fix you up.  (The more garbage trucks out side the hydraulic repair place the better!! )

They are square section, otherwise it would be a very easy fix!

Are they like the backer O rings used in the Sundstrands between the pump and the hydro motor??  In any event a hydro shop would have square rings as they are not uncommon in hydraulic land.
