    It is a Dewald hydraulif leveling system for my RV. It has a control panel to extend and retract the jacks to level the motor home. It has an "all extend" switch and it has a rear jack switch and two more switches to adjust the front and rear jack to get level. The "all extend" switch will not lower the left rear jack, but the switch that controls the left rear jack will lower it and then we can use the all other switches to get level.

Im looking for an owners manual for my RV Leveling jacks. I have 1991 American Eagle Diesel Pusher all I know is there are 4 hydraulic fluid leveling jacks

Like any number of items on motorhomes the builder will use what's available at the time; there is no one make of leveling jacks that they used on that coach. However you should be about to contact a Fleetwood dealer and see is they might have a lead for them. American Eagle are the high end coaches by Fleetwood. What is it you're trying to do with your jacks? The jacks themselves are pretty basic; they're like a number of other hydraulic cylinders in the principals of how they operate. There are times that if you look for generic hydraulic parts they are cheaper, or better quality (or lower depending on the original build).

Motomaster motorcycle jack won't raise

Hi Bogdan:
Seems there may be some confusing instructions.
Here's what I would try. My approach would be intended to get the bike off the stand before I tried to trouble shoot the motomaster jack.
1) Use the handle to rotate the release valve to the right (clockwise) until it is snug.
2) Pump the jack to try to raise it. If it raises, then press the release pedal and use the jack handle to slowly rotate the release valve to the left (counter-clockwise) to lower the deck.
3) If it does not raise, I would use a separate jack to raise it, then follow the prescribed lowering procedure, and at the same time, use the control on the extra jack to manage the lowering.
Once you get it partially lowered, hopefully the motomaster jack will start to function and you can lift the bike far enough to remove your extra jack.
Hope this helps.
To let me know if it works for you, please reply as a comment to this post..

Where Do I Fill Oil Into My Car Jack?

Usually only oil has to be added if the jack will not pump up, not down. They go down either by added retraction springs or by the weight of what they were lifting.
Anyway, look for a small rubber plug about 1/2" in diameter on the hydraulic unit, lay the unit on it's side so when the rubber plug is removed the oil won't run out. Once you remove the plug, fill it up with hydraulic jack oil from an auto parts store. Put the plug back in, you may have to work the jack to purge air bubbles, by pumping it up and down a few times.

1995 bmw 525i

Very common BMW problem. The front lateral arms that support the front to rear motion of the wheel. BMW calls it the upper, lower support arm. Two arms connect there. one left to right (think typical lower control arm, and this arm) It has a ball joint that connects to the lower most part of the strut and extends rearward to the rear crossmember and has a large bushing pressed into the arm. You can replace just the bushing if the ball joint end is ok. Bushings are about $45 each and you will need a press.
