Of course I can't actually recommend you'd do this.. liability and all. If you have a hoist or support such as the one in the 700/900 FAQ, that might help keep the engine in place better than a block of wood. Dunno how strong the crank pulley is, etc. Don't go loosing a digit, limb, life, etc.

Dear Scott,

Thanks for an informative article on 240 series motor mounts in the Jan/Feb newsletter. I have owned three 240s in the last 18 years with a combined total mileage of 690,000 miles. I have had to change motor mounts numerous times. You are right, it's a pain. Have you ever tried removing the complete mount assembly including both brackets? you might consider trying it.

I supported the motor mount under the crank pulley with a wood block. I removed the three nuts that hold the bottom half of the motor mount bracket to the front cross-member. I then removed the three bolts that hold the upper part of the bracket to the side of the block. I raised the motor with the jack to clear the bracket bolts from the cross-member. I removed the complete motor mount assembly with both brackets intact and disassembled the mount in a bench vise. No turning wrenches a half flat at a time. I cleaned the mount brackets, and installed the new mount between the brackets, keeping the brackets oriented in the proper direction. Used a torque wrench on the mount nuts. Installation was the reverse of disassembly. Using this method saved me 2/3rds of the time from the old method and using swear words. One giveaway for a broken transmission mount is the transmission popping out of second gear. The trans drops to the point the gear lever interferes with the opening in the trans tunnel.

Happy ReVolvoing! Regards,
D.W.

We tried this method and it is much faster, the only caveat is to make sure that the motor is safely supported. If it were to slip off of the jack at the wrong time, fingers and hands could get crushed. One solution is to cut a piece of 4"x4" wood and place it on top of the engine cross member, just under the oil pan. Might dent the oil pan if the jack failed, but it would save your hands.
Thanks for the great tip D.W!"
