Happijac Blowing Fuses
Blowing fuse for left rear jack. Found some old posts and a couple of things to try (removing motor, blowing it out and re-oiling bearing seems to be the best solution short of replacing the motor). ...

Done/fixed. Popped cap off (after melting ice inside). Blew dry. Wd40. Blew that out and dribbled 20wt in there as best I could. Will do a more thoughtful job when not so far below freezing. For those that have toron into these, I assume, based on end housing shape, that it actually has sintered bronze bushings and not bearings. Is that correct? If so, 20wt (3 in 1) is ideal. Just went through this with a pellet stove blower. Thanks. Oh, a couple of wraps with a screwdriver handle in the bushing location freed the motor.
Watch the lube job on top of the screw jacks (under the gear head)... in the manual position you disengage the electric motor and the clutch can be lubed too much to hold and the jack will let the camper come down. Very dangerous.
