Small leak on 422 front wheel motor

J_J · Jul 22, 2009

What do you guys think on rebuilding or replacing with new on those hydraulic wheel motors? I would think that anything over 1/2 of new to rebuild, I would go with new.

Hi Bob,

Do you know the exact model number of the wheel motors on your 422?

Thanks!

No, I don't. Part of the reason that I have not done anything.

When I got mine repaired it cost almost $300. They replaced the shaft because of corrosion/pitting around the seal. The new from PT was about $305. I will probably not rebuild it again.

I have three used 12.5ci White RS motors that I took off mine when I did the wheel motor upgrade to CharLynn 22.7ci. If anyone wants one as a spare or backup, PM or email me with an offer.

That price doesn't sound too terrible for a new one... I will probably give PT a call about them.

Hi Kent, if they are in good condition and you believe they would work on my 422, I might be interested in one. Do you recall how many hours were on them?

Kent,

Are those motors 1500 psi motors? What is max rpm?

Not an exact number, but somewhere around 450 hours on them. My 425 is at about 550 now.

They are 12.5ci White RS series, JJ. They're 1500 psi motors, about 140 RPM at 8gpm, as I recall. The complete specs are on White's site. Remember that these have a 1" tapered shaft, due to their use as wheel motors.
