How much hydraulic fliud leakage is OK on up/down cylinder of Kubota snow blower

[wacnstac]

Hello, I seem to be leaking a fair amount of fluid from the up/down cylinder of my kubota snow blower on my b2650. Not a ton, but enough to leave a spot on the cement floor of my pole barn after each use.

What if anything can I do about it? I have been letting the tractor warm up for at least 10 minutes before blowing and the last time I used it, it was about 25 degrees outside.

Actually NO amount of leakage is acceptable. Appears that the cylinder requires a replacement seal kit installation. If the piston is pitted or otherwise scratched or damaged, it may also require replacement. It is important that the rubber wipes be replaced in conjunction with the seals. Is there a hydraulic service shop in your area??


Many smaller dealers subcontract this work to jobbers. Are you sure it is the cylinder and NOT a hose/fitting ?? By chance is the unit still under warranty??

If you have Kubota insurance and there was an "incident" where the cylinder was effected, they are pretty fair about covering the repair less deductible.

Do you actually SEE the leak source of just floor spot?? Some leaks do not appear unless cylinder is under significant load.

Well I had the seal replaced this last summer. I've used the blower a few times so far this winter and still have a smaller amount of leakage there. I've noticed that most of these I've seen online have the cylinder mounted seal down. Mine is mounted seal up. I wonder if this would make any difference? I honestly wouldn't think so.

If the seal was done this past summer, and is leaking, then it wasn't done properly, or there might be a nick in the chrome cylinder that is damaging the seal, causing the leak. If that is the case, they should have advised you about the damage before they rebuilt the cylinder. Cylinders repaired properly should be as good as new. I purchase the OEM repair kits, and take the cylinder to a shop that specializes in cylinder repair and hydraulics. Small cylinders like yours cost about $100 to have the seals replaced with you supplying the kit. The shop that I use prefers to use the OEM seal kit, rather than there generic seals.

I had the seals redone on my quick hitch last year. No leaks since (was leaking a bit before repair, during the winter).
Had used the hitch/cylinder for a few years before, with no issues, then out of the blue, it started leaking one winter. Kubota wanted an arm and a leg, as well as my first born, for a new cylinder. Took it to a hydraulic shop to get it re-sealed at about 1/3 the cost (still was expensive..). If you can do it yourself, even cheaper...
