Thread: Jacking Points on a 45' with Independent Front Suspension

    Try to keep in mind that the supports are for the body of the bus. If you look at the body support points it will make sense.

    Jacking the axles for tire replacement isnt the same.

    I would call a prevost service center and see where the body support points are for a 45. I looked at one in Sevierville and would think it has to be behind the tag, not in front of the drive. I would guess that 60 percent of the bus weight is at the point in front of the drive axle.

    Bill Jensen also referred me to the updated manual on the Prevost site. I went to the Technical section of the Owners manual for my bus and found the updated Jacking points for the independent suspension. The manual validates what Bill had told me. The jacking points are the exact same as on the straight front axle.

    Ray, This is the link. Once I selected my "Vehicle Type" and "Year", I found the information in the "Owners Manual". Had to go to the index and search for Jacking Points.

    For pit owners, if the forward body support points are the same for solid axle and IFS, then it is just forward of the wheels and inboard slightly.

    That point on my coach when over my pit is outward from the pit opening based on how my bus is placed over the pit and there is no problem or concern with the placement or too much stress on the sidewalls of the pit.

    The picture shows the relationship of the stands to the pit which is 24" wide. I could actually move the bus forward and still have more than ample access if I wanted to get more room between the stands and the pit wall. The spacing in the rear is similar and that is where twice as much weight per stand is concentrated.

    I should add that the weight, evenly distributed on the base of the stand at the rear of my coach amounts to around 250 PSI.

    Jon,

    The manual does show those front jacking points also, and I don't think it could hurt anything to use those points. When I mentioned this to Bill, he said they recommend using the points behind the front wheels instead of the ones in front of the front wheels.

    My understanding from Bill is that the points behind the front wheels are where the frame joins in 3 different spots, and therefore, offers the best support and the least stress to the frame. He said that was the reason on some of the buses, there was actually a pad on each side behind the wheels to mark the jacking spots. Once again, and especially for using the stands to store the bus, I feel sure either location is fine.

    I have used both the ones in front of the steers and the ones to the rear. Lately because I have gotten into the habit I have been using the front ones and see no indication of any stress on the frame or shell. I have opened and closed doors, bays and windows and everything opens and closes just the same as when it is sitting on the wheels.

    My information on supporting the coach showed the front support only, but if the rear support on the front frame is used it will actually reduce the weight supported at the rear which may be a good thing.

The lady I spoke with asked me about this manual and I did not have it so she sent it free of charge.

    Denny, When you have a chance could you give me the manual edition # of the book. I can't find a person at any of the locations I have called that understands what I am asking for. Thanks, I will be out of town for a few days so take your time.

    Jim,

    This may be the book that Denny is referring to. I couldn't find anyone at Prevost that knew of the book.

    This is the link that Bill told me about on the web. This is the Owner's manual, and you can also view the Operator manual and Maintenance manual.

    If you open this link, select "XL MTH, "1998", "Owner", and under Manual Section select "Starting and Stopping" hit "Search". When the page comes up, select "Starting and Stopping" and go to page 4-20, you will see the jacking points for the 45' XL MTH.

    There is also a good section in the Maintenance manual about tire pressures. I noticed it recommend that we run 90 lbs in our drive axles with either 12.5 or 315 tires.

    Default Owner's Manual

    Jim,

    I checked on the manual and it is the "Owner's Manual". On the left front cover is PA-1111 and on the right side of the front cover is AS/T-05. I think this is the book that Dale was referring to. The printed version is much easier to read and look up info in than the computer version.

    I called Canada to check on recalls on my coach when I bought it and the lady I spoke with asked me if I had the manual and she sent it to me. It answers a lot of question and shows exact point for jacking.
