Rear seal leak on Cummins and need to pull Allison MD3060

Here is the link to get into the Allison Source Documents. The will likely have all the info you might want.

FWIW you will be working under, not on, your MH. This equipment is killer big. Do you have air bag suspension? You will need to block the travel so a sudden air loss doesn't crush you. Pick up sized equipment is too small for the most part. I use a 22ton air/hydraulic jack and 12ton jack stands on a concrete pad.

Be Safe!
