slide adjustment

[swanny]

well it was very nice here in Pa today. so i got under my monty and laid there just looking around. i don't know why i was under there with the sun out so nice but anyway. LOL
while looking around i noticed the hydraulic cylinder on my living room slide. the lock down nuts on the end of the shaft were not tight against the flange. this let the threaded part of the shaft slide in the hole. i don't think this is right but i'm not sure. my only thought was, that is the maximum the shaft could be extended, which is farther than the slide can travel. so i'm asking the experts here on MOC

i do have pics but, can't figure out how to post (mac)

The lock nuts on all of the slide cylinders should NOT be tight against the bracket. The cylinders have more stroke than is needed to fully open the slides ... thus the space between the bracket and nuts. If you were to tighten the nuts solid up against the bracket, something's going to give and I can guarantee it won't be the hydraulic cylinder! There is an adjustment procedure if you have a problem ... contact Lippert or email MIMF here on the MOC.

sounds good to me. makes sense. thanks

swanny,

dieselguy is absolutely correct. The cylinder pistons and shaft have more stroke than the room does. The gap is set so that the room seals in both positions with the piston inside the cylinder tube bottomed out to the endcaps of the cylinder. That physical obstruction keeps the room from sucking in and setting on the floor of you coach or keeps the operator from blowing the room out thru the side wall and laying it one the ground beside the coach.

Sound a little exagerated? Probably. But, I guarantee that if those nuts are jammed together against that driver bracket, you will break something and it won't be pretty. That hydraulic pump produces 2200 pounds of pressure per square inch of piston suface. And , if I recall that piston is about 1.750" in diameter.

When I worked for Lippert several years ago, I received several calls where retail customers saw the samething and made adjustments before contacting us or Keystone........they were not happy with themselves.
