Transmission removal on truck w/brakesaver retarder

those must be some long flywheel bolts behind that clutch.

 

Hey you are the mechanic lol

 

I did mine on my 3408 a while back and it will be just the same as your 3406. There are long bolts which go through the Brakesaver to the flywheel housing. You have to attach a plate to the rotating part of the Brakesaver or you will ruin the seals. Check out the first few pics here of when I did mine

Also a pic of the plate you bolt to the rotating part.

 

Bit behind, bet ya got it out by now. Yes, you remove the bolts holding the trans on and the retarder has a few allen head countersunk bolts holding it onto the flywheel housing, no worries, guide studs are handy to a degree none the less. Then, look close to see if the retarder seal(s) are leaking, if so, nows the time to re-seal it, especially if you are doing a resto and it has been sitting, perhaps a rear crank seal also? Take care.

 

Yes, because there is nothing to hold the rotating part off the seals. I borrowed it off CAT, also the lifting tool. Once the long through bolts are removed, there are a few short bolts holding the Brakesaver to the flywheel housing.
