Jack issues

Pre-emptively rebuild the jack seals or drain unknown fluid and refill and see what happens?

I topped them off with the jack oil and got the camper off the truck. I'll order parts to rebuild them over the winter.

Good news.

cold will do that with the wrong type of oil.. people put what ever in these but transmition oil is the best to use, wont get sluggish when its cold, isnt as hard on the seals doesnt rust out the insides like motor oil and hyd oil will do. I just had mine all rebuilt and got to see the effects of using the wrong oils in them.

But, they were rebuildable.

There is a bottle of jack oil in the camper so I assume that is what has been put in.

mine always had the trans oil that hijacker recomends. the guy showed me a few that were not rebuildable because the owner used motor oil in them. hyd oil works just gets thick with cold and then has issues , other oils attack the seals and dont rust protect that great. I learned a lot of stuff about hydrualic jacks from him (one of the original employs of hijacker who rebuilds them for people out here on the side now that the company is defunct. does pretty any brand of hydrulic jack.

I had a set of the same jacks on my coachman ranger bu they were called hijackers. Two things did what your describing, low oil and the shaft needed a some new rubber gaskets. Probably not low oil if there is no evidence of a leak but if you never checked them or it's been a while maybe. I'd replace the oil if not leaking and get some new rubber seals. Also the cold affects hydraulics some what. Good luck!

similar to the set I had but much much older.

These are the gaskets I'm talking about. I replaced them and they were
like new.

Sorry if they're not the same...

Thanks for the insight. I'll check the oil to see if that is a portion of the problem. I intend to rebuild them over the winter. I am sure the fact that the highs are in the 30's right now is a portion of the problem. It is likely impacting seals or oil in some way. Better to happen here than somewhere else.

Maybe it will have to stay on until I get those jacks rebuilt. Not the end of the world and a better solution than dropping it trying to get it off.

Great! glad I could help as it was described to me many years ago is that the rubber seals get air in them. This creates a dry rot area and also can freeze and defrost many times until they fail. When I replaced them in all 3 jacks they looked and felt like they were new but low and behold the new set fixed the problem. The fourth jack had obvious deterioration. Broken seals etc... I'll see if I cant find the old pics.

Check the battery in the remote. I've had mind go silent and went knutts for a few days, till dealer thought it might be the battery... If you have a back remote, try that or undo the remote to get the battery and get another 2-3 as backups..

No remote. Hand pump jacks
