Leveling jack pad replacement
 
Well after dealing with the leveling jacks popping for 1 &1/2 years I finally got Equalizer to help and they acknowledged that the jack pads were defective. Well after waiting for 2 weeks for them to ship me replacements I contacted Andy Thompson at Forest River Diesel. Andy sent me 4 new pads pronto.

I proceeded to change them out and got 3 of 4 done with no sweat, The 4th is really being difficult. My approach has been to grab the chromed pistion/rod with a rubber strap wrench and then use an impact wrench (520 ft-lb capable) to remove the bolt. This last jack bolt is really stuck good. I've tried every penetrating oil known to man combined with some heat and cold (spray C02) and no luck.

Anybody got any ideas?

Cannot help you with removing the pad, but perhaps you can answer a couple questions. I heard that some pads are punched through with a large bang after being chipped away and the coach falls down on that side. Is your defective pads in this class? Also is the noise that you experienced from this problem?

Thank's

The bolts that retain the pads to the piston were bottoming out on the ground, concrete or whatever they were pushing on before the pad made contact. The bolts were thereby taking the majority if not all of the weight of the motorhome. If leveled on concrete I could actually take the pad and spin it so actually the pads provided no support. The pistons had not punched thru the pads and there are no signs of distress on the pads. The sound I believe was the pads rattling around whenever the weight in the motorhome shifted (i.e., I rolled over in bed). It was more of a clunk and would usually occur at any of the four pads at one time or another frequently. Hope that helps.

Have you tried a breaker bar with a cheater, sometimes a dead steady pull will move it.

Try hammering with the impact wrench tight, loose, tight, loose.

Yep. Tried both. Since I can only hold the chromed piston/rod with a strap wrench. I can't provide enough resistance for the cheater bar approach to work.

Try using steady pressure on wrench and hit the wrench with as big a hammer you can handle under the coach with out messing anything else up. This will probably after several blows with the hammer loosen it up. Next step will be to get a hydraulic wrench since you can not use torch to heat up without a big fire that you do not want. CO2 might work if you can get enough firectly onthe bolt to freeze it. Also you might need to recruit help to hold strap wrench

Try using a large pipe wrench.. (With a piece of rubber for padding so not to mar the cylinder) to hold the cylinder while you go at it with the impact gun..

No doubt that chrome plated cylinder is very hard but some pipe wrenches have sharp teeth and they will dig into it need to make sure that padding will protect it. I have saw them dig in to a 4" compresser cylinder rod on a natural gas compressor and they are very hard. how big is your impact wrench 1/2" drive of so you may need 3/4" drive that has a bigger internal hammer. They can be rented at lots of tool rental places.

Not sure I'd use a pipe wrench on a polished Hyd cylinder but anyway if its that difficult to get loose after you've done three, something may be seriously wrong. It's not difficult to remove the ram. Disconnect the two hydraulic lines with bucket to drain the tubing. Remove a max 8 maybe 3/4 inch bolts and take the entire assembly to a machine shop. Chances are the bolt is thread damaged from the load and you won't get it out w/o major damage.
A shop can get it out, chase the thread and reassemble for you. Just my thinking, if you strip it, you'll probably go to shop anyway or buy new.

I agree..But if he cleans the cylinder then wraps it a few times with a let's say rubber inner tube ....it should hold enough without digging in.... But you are correct..he should be careful.
