joefromperry Posted April 27 Share Posted April 27 I need to pull the side radiator from my signature because of a leak. Having learned from a prior experience doing this, I'm going to build a couple 2 x 12 ramps to lift the back of the coach to facilitate radiator removal. My question is: do I need to make the ramps long enough support the tag wheels, too, or is it okay to just have the two sets of drive wheels on the ramps? I'm thinking since the tag is sometimes lifted by the chains, it would do no harm to not have them on the ramps. 1 Link to comment Share on other sites More sharing options...
Just Jim Posted April 27 Share Posted April 27 I have asked this question in the past and was told that they need to be supported. I had similar thoughts as you regarding lifting the tag. Link to comment Share on other sites More sharing options...
Solution Garry Donohue Posted April 27 Solution Share Posted April 27 I made ramps that use 4ea 2X8’s staggered to make a ramp. As a 2” thick piece of wood is actually 1.5” thick, it raises the rear by 6 inches total, which is enough to get under to do work plus it is not enough to cause the tags to be lifted off the ground.

96 EVO Posted April 27 Share Posted April 27 My latest version of ramps has my drive tires on 3 layers (4.5"), and the tag tires on one. So the tag tire sit 3" lower than the drives. Link to comment Share on other sites More sharing options...
amphi_sc Posted April 28 Share Posted April 28 How about driving onto the ramps, raise the tag, put boards under the tag, and lower the tag. Thus avoiding the limited space to wedge in a ramp for the tag but still having the tag support some of the weight long term. Link to comment Share on other sites More sharing options...
dl_racing427 Posted April 28 Share Posted April 28 Static load on the drive axle won't hurt anything, even if somewhat over the rated load. That rated load includes a generous allowance for dynamic and shock loads when driving and transmitting torque. Think about the severe bumps you hit at highway speeds. Sitting still, it would likely support well over double it's rated load without any damage. The only concern would be overextending the tag air bags. Lift the tag and the chains should prevent that.

Gweedo Posted April 28 Share Posted April 28 (edited) I just built ramps two days ago to work on ride levelers. I used 2x10. 5 levels. 5’ 4’ 3’ 2’ 1’. Worked awesome but I don’t know about the tag sorry I don’t have one. $90 to make 4 Ramps n they cut the sizes. Edited April 28 by Gweedo Link to comment Share on other sites More sharing options...
Keith H. Posted April 29 Share Posted April 29 Can someone post a pic or two of these ramos? Link to comment Share on other sites More sharing options...
Garry Donohue Posted April 29 Share Posted April 29 I made 4 Ramps total. 2 on each drive tires. The tags stay on ground 6 inches below the ramps. Place the ramps in front of the drive tires. Take a tape measurement from the lower ramp to the center of the top ramp. That is where the bottom of the tire will end up on the ramp. Then take this measurement up front to the steer tires. Measure from the front of the steer tires forward and place an item on the ground out and away from the tire so you can see the item when you look down out your side window. Give her just a little throttle and roll up and STOP where the bottom of the steer tire is in line with the item you left on the ground. This will cause your rear drive tires to end up exactly in the center of your ramps. 2 Link to comment Share on other sites More sharing options...
Gweedo Posted April 29 Share Posted April 29 (edited) I could do without the top but it was pretty nice being able to sit up under there Edited April 29 by Gweedo 1 Link to comment Share on other sites More sharing options...
cbr046 Posted April 29 Share Posted April 29 My parking spot isn't level so I need 3 ramps (one wheel is the "reference") every time I come home. Fun stuff. Don't forget a block of wood to keep from dropping over the edge. - bob Link to comment Share on other sites More sharing options...

UPDATE: As it turns out, I didn't need to make ramps, as I ended up backing the coach to the end of my "built-up" area so the radiator was able to be lowered without them. However, some great suggestions and pictures, which I'll definitely file away for the future. Thanks to all who replied. Link to comment Share on other sites More sharing options...
96 EVO Posted April 30 Share Posted April 30 I 'need' ramps for greasing the rear of the chassis! Link to comment Share on other sites More sharing options...
