My late model i bought a few years ago had a rattling coupler.. plus it looks crappy with my mp plenum so i tore it down to replace coupler, bearings send case off to powdercoat etc.. This is where things got interesting! First off when i loosend the plug to dump the oil out, Oil blasted out of it all the way to the celing of my garage! I'm assuming bearing plate seals are bad! this had some serious pressure and it had been sitting over a week! Next thing i decided to knock out the devcon/jb weld whatever crap in the silencer ports and weld strips over them. Well further inspection of the inlet i find this:
It looks like crap! almost no lip to seal it and a bunch of devcon crap all over in there! (fixed two stripped out holes with metric thread inserts too btw)
This is after i ground away every trace of the devcon (probably jb weld as it turned to dust as soon as i hit it with a carbide bur!) Note: the sealing surface by the bearings is crap too!
Clamped a piece of 1/2" steel to the bottom to absorb heat and as a guide since the alluminum wont weld to it. Slowly started building it back up from the inside out VERY carefully allowing it to cool often!
A little bit farther along
Used a 1/2" endmill to clean up the rough stuff then a fly cutter to resurface it all nice and true!
ordered a 5/8" to 15/16" expandable reamer to clean up the bearing holes VERY carefully they have some high spots from welding.
this is when i was cleaning up the enside with an angled end mill
Strips welded over silencer holes (yes the welding here looks crappy but they are not going anywhere!) Note: very tricky to weld an 1/8" strip to the case without just melting the 1/8" lol but not nearly as tricky as welding up the flange was!!
Sticking the case in the mail tommarow to get powdercoated MP silver to match my raised top i built my new return plenum and my MP inlet! When it gets back i should have my rebuild kit here and also the reamer i ordered! Note: I am replacing the bearing plate and rotor pack with a low mile uncoated one for now since somthing is going on with the seals in my coated pack. I will get a set rebuilt and recoated before the shootout though! Hope i dont loose much boost but my coating was pretty much trashed! This thing made 15/16psi at 5% with cam ported heads and full exhaust.
