Lift points

[Venturer]

Where are the jacking/lift points on the Roadmaster chassis with air leveling? I assume the axles, but does one rely on the air bags to remain inflated to change a tire?

I’ve Always use the axles 

[Dr4Film]

When changing tires they lift on the axles evenly from side to side so the body doesn't get tweak.

You can raise the body on the air bags then block the frame from the chassis to prevent it from lowering.

[Venturer]

Thanks. It was the chassis to frame area to block that I was wondering about. I won't be doing any changing, however, I want to know where in the event it's needed. I'd like to know it's being done correctly and safely.

Some guys want to put a jack in the center of the axle & lift both sides with one jack,  don't let them do that,  it can bend an axle.  Even the front axle.

X2 on this, unstable and the coach could tilt.

When I had my tires changed they used two bottle jacks, one under each side. 

[Venturer]

Then you rely on the air suspension to keep the body up? There must be body support places to support it for changing air bags.

My coach has jacks instead of air leveling.
For long term storage, I raise it on the jacks, and place properly rated jack stands under the chassis, then retract the jacks to protect the rams from corrosion.
This keeps weight off the airbags and tires, and to lift a tire only requires a regular floor jack under the axle.

Look for points on the chassis that the suspension ties into, and that have vertical members running up to the main rails for strength.

[Venturer]

Thanks, I'll do some searching. After several coaches, this is my first one without jacks and my first Roadmaster chassis.

You don’t need to support between the chassis & house frame to change tires.  As mentioned, the use of 2 jacks is most important to lift coach equally on both sides under the axle.

I realize that, which is what I would do. However, I like to use a safety backup for the "just in case" event a jack would fail. I don't want the body coming down on myself or a service man. Maybe it's not needed, but it only takes one time to ruin one's day, or worse.

I made 8ea 2x2 square tubes with saddle on each end and put them next to each air bag then lower the coach on them... When I get back to the toy barn I will take pictures of them with measurements. Seam to work great...

I was only referring to the event you don't need to go under the coach to change tires.  When I get under the coach, I drive it up on "DIY" ramps or I would really prefer the square tube method that Michael will be providing us when he gets pictures posted.

[Venturer]

Thanks. I've built the ramps in the past, but they're gone. The square tube support sounds like the answer to what I want.

I have two one foot sections of PT 4x4 which I place between the rails and the frame body after it has been raised up on the air bags. I release the air from the bags which secures the 4x4 in place. That allows me to easily crawl under the coach and work on various locations.

That is what I need. So 12" is the correct length?

send me the pictures to brownjrpaulj@yahoo.com. thanks

Ok got pictures of 2x2" tubing here are the pictures of what I use...The only modification I would do is use the wide u bracket on both sides put one at each air bag and let the air out of the air bags...

4 inch square tube 5/16 wall 11 inches tall.

Two points having had mine for 15 years now.

A)I know and saw 4x wood split...not mine

B) A friend made his 12...with just a little uneven ground one side got stuck.  Hyd jack in there to get a little lift...not fun.

C) This info for tag axle RR10 chassis only.

D) They fit neatly laid down next to the 150 gallon fuel tank so you can have fun on the road occasionally too!

Happy New Year

I emailed you 2 of the 4 titled “Monaco braces”.  Since he said he’d make both ends 3”, you don’t need the other 2 pictures.

[Trevor and Laura]

Good Morning,

                         I am also unable to open those pictures and would really appreciate having them as jpegs, email is qcktvr2@gmail.com

Many thanks

     I was able to open the files above and attach as .jpeg.  If that’s not allowed please remove.  Since the OP of the pictures attached them here, I assumed that is consent to share.

 

[Trevor and Laura]

Thank You for the pictures and description, did you consider using thinner tubing, 5/16in seems prtetty hefty, but no doubt very safe.

Regards, Trevor
