Happijac lubrication

Since taking mine apart, I know that even with a hole drilled anywhere you want it, you absolutely can not properly lubricate everything that need it without a dis-assembly. Plus the complete dis-assembly is not a chore.

Two screws remove the motor assembly. One plastic plug and the "shift" lever removes the nylon motor socket "clutch", and one "E" clip removes the manual drive socket and the top gear. Lift the bottom gear out and a roll pin slipped out releases the entire lower telescoping section.

I then removed the 6 screws to remove the top motor/gear housing and greased all of the gears in the top gear assembly.

I used a small tub of Liquid Wrench white lithium grease that I bought from Carquest. That is some sticky grease. It will surely outlast whatever the factory used.

I spent about 30 minutes per jack and I now have complete confidence in my jacks. I would also be very comfortable dis-assembling one if a failure should occur while traveling.

Excellent, that's the steps that most of us do...

I use a Battery operated 1/2" drill and adjust the chuck to fit the top of the screw shaft...I can run that screw each direction and lubing extra where needed...

The first time I did mine there were places that the screw would bind and stop....WD, wire brush and elbow grease prevailed and the screw freed up...That was over 9 years ago...

The first time I thought I needed to do something about my jacks was when we were on a trip....Took the camper off and lowered it about 1 ft off the ground....I noticed that the front passenger jack was struggling/groaning....

When I started to put the camper back on the truck....that jack was really struggling....I did not think it was going to make it!!!
This was before we knew how to take them apart!!! I learned!!
