hey im thinking of replacing the back side housing on my engine.. can i jsut replace just that section of damaged stuff or do i have to rebuild the whole engine? i mean i would like to jsut get a new rear plate and get new seals for that plate and call it done...

 

What'd you do to it, crack the rear dowel?

 

Tubular down leak as I remember from the previous thread...

Yes, it has been done before. Generally you want to put the stack vertical with the rear facing up. Use big clamps to hold down on the rear rotor housing then break all the tension bolts free, recheck your clamp pressure and lift off the rear iron.

The key apparently is to make sure the clamps are tight enough as to keep things from moving, but not too tight as to bend anything or crush.

I might consider doing this if I had a low mileage engine that had a minor problem like a pinched o-ring, but I wouldn't do a high mileage engine this way. After time, too many things get set into place and disturbing them can cause leaks.

 

I would say its a matter of "while im in there..."

I mean for the amount of trouble you'll go through JUST changing the rear iron and seals and then STILL HAVING THE POSSIBILITY of putting it together and having a little kaput action.........you may as well just tug the motor and freshen it up

 

i have about 15-20k on this motor.. oh and why am i being lazy.. cuz i dont have the garage to spend a few days cleaning a whole block. i live on a base where time cost money for space.. and facilities arent conducive to rebuilding...

 

has anyone seen where these plates normally crack cuz if its not interfering with the rotor i may just jb weld it shut but if its a long crack i wont do it (obviously)

 

JB Weld has a problem holding up to heat and pressure that builds up back there
