Hi, new here at bigmacktrucks.com, I have to replace a clutch in a 1999 mack that was a snow plow truck for penn pike. Its got an eaton 10 speed in it. What is the easiest way to remove the transmission and support the engine. First time for me to tackle a transmission with the engine mounts on the transmission.

A bottle jack under the engine bell housing!

Are you sure it is an Eaton/Fuller transmission with the rear engine support mounted to the transmission? I've only seen Mack transmissions using this setup. Eaton/Fuller usually use the rear mounts attached to the flywheel housing leaving the engine supported while the transmission is removed from the chassis.

Rob there is a notal mount with mack mount set up on it for RR. they are about a 1000bucks down here. I gave up trying to get one for the spicer.

that clutch is heavy, I just did the 866 on the ground, what a battle. a 4000lbs twin plate is one horrible thing to fit. :)

Yes they are heavy. I made a plate that bolts to the saddle of my transmission floor jack to support the weight. It uses an old input shaft to center the discs. After clutch buildup I remove this adapter, set the trans on the jack, and go abouts it. No doubt about anything being heavy to work with.
