Has anyone found a viable solution to keeping final drive input shaft seals from leaking on JLG G10/G12 telehandlers? We have had a ton of issues with these seals. What we've tried so far:
-Replacing the stub shafts. Gets expensive if you have to do them 5+ times over the 7000 hour lifespan we keep the equipment.
-Polishing out shallow grooves with emery cloth. Time consuming.
-Speedy sleeves. Hit and miss. Sleeves are only slightly wider than the seals. Placement needs to be exact. Find that the sleeve tends to be cut easily by the seal. In some cases if the tech just installed the sleeve dry or with silicone rather than retaining compound, the sleeve comes apart and obliterates the seal.
-Sent stub shafts out for machining and chroming.
-Updated seals.
If anyone has any suggestions on how to improve the longevity of these seals that'd be great.
