Topic: 40 Merc trans removal and reinstall


oldguy    -- 03-16-2012 @ 9:09 PM
  Hey Guys,
I am getting ready to remove the trans from my 40 Mec and noticed that the rear mount is rivited in and the wishbone is quite close to the bottom of the trans. Can the trans be removed and reinstalled without removing or sliding the motor forward, as things seem really tight. If so what steps should I be following ?

  HI Old Guy, from someone almost as Old:

You dont need to move the motor forward, you pull the rear axle assembly/torque tube back. Unbolt the bell, and the trans rubber mounts. Unbolt the trans from the motor. Pull the trans back, separating the u-joint, then pull the trans up and out. I was able to lie down, and pull the trans up onto my chest, then slide out of the car.
I would suggest a shop manual to follow the steps.
Good luck,
Alan

  Sounds dangerous, especially if you are skinny enough to put the trans on your chest and slide out since that car would have to be high off the ground.

  Remove the transmission by pulling it back far enough so the input shaft clears the clutch, then lift it up and out. We use a big metal hook that is inserted into the inspection hole to move the transmission, and to provide for handling it. If you must try to drop it out, use a transmission jack. The unit is heavier than you might think, and it will cause injury if you drop it on yourself. They are always covered in grease, and hard to handle. Be sure to support the engine with a board under the oil pan, held up by a jack.

  As far as dangerous: I must disagree. I am over 6ft and 220 pounds. It was easy, and the car does not have to be high off the ground, the front tires were on the floor, and the rear of the frame was well supported. The trans is heavy, but held close to the chest, I was able to move around easy enough, and I am not so young any more. I just offered one way that worked for me. I do like the idea of using a hook, or puller, if you have room to manuever around without damaging the body.

  As a rule, I don't lay under anything I am unfastening. Nor do we allow our shop guys to do it, either. The hook we use is similar to a hay baling tool, that us old guys remember. it is about 18 inches long, and made from a piece os 5/8 steel rod, bent to form a handle on one end, and a good size hook on the other. I straddle the opening in the floorboard, hook the inspection hole, and slide the transmission back and up. In some cars or trucks, unbolting the seat gives more room to maneuver the transmission.

  Hi Guys,
Thanks for all the responses/advise.I did as suggested with help from son-in-law (much younger and more flexible), using a jack with a flat plate for stability under the trans, we lifted back/up/out.Had to raised the back of the motor up just enough so the bottom rear of the trans would clear the rear mount bracket.
More fun putting it back.
Thxs again.
