I'll start by saying I am very mechanical, rebuild engines pull and install engines, trannies etc.
But my RV has an Allison MD3060 behind, rather in front of, a Cummins 230hp on a Winnebago pusher. 1993. Great running rig with a rear seal that leaks on the Cummins. The MD3060 is big. Anyone know the weight? Is this doable with a couple guys and a tranny jack? The job seems simple enough it's just the sheer size that gives me pause. Anyone done it and have advise? If I do trannies I usually replace the front tranny seal while it's out. Is that something I would want to do here too? Any specialized equipment other than a heavy tranny lift that's needed?
srukke,
Well Sir, first off I applaud you for even thinking about doing a job like this yourself. Based on your reported resume, it sounds as if you'd have no problem doing it. Yep, I know the size of some of this stuff can be intimidating but, in most cases of repairs on these rolling Kleenex boxes, it is ONLY size that's different.
You see, back a while ago, I had a left rear axle seal leak on our '04 Itasca Horizon 36GD with the C-7 330 CAT. I'd seen the same types of axles out a zillion times before, while working overtime assignments in our Fire Dept. repair facility. I figured, what the heck, let's do it. So, I jumped in with both feet.
And, as expected, pulling that axle was almost identical to pulling one on a 3/4 ton pickup. Replacing the seal, was also almost identical with the exception that, it was considerably LARGER than a pickup axle seal. So, I improvised. I made a seal installer. It worked flawless.
My point, as one poster above me stated, just get the correct tools/jacks etc. and you'll be probably $1700 ahead of the game after purchasing the seal and, renting the correct tools. Heck, if I were closer, I'd dive in there with you and I'm getting too old for this stuff. To me, some of this stuff is actually still fun to do. I just helped a buddy replace a front wheel seal on his '06 Itasca Meridian 34H. The technical side was almost identical to the rear seal replacement on mine. Piece of cake.
