    It does go on the green side for the stock coupler.

    Here's some solid couplers: http://motors.search.ebay.com/search...rclo=&saprchi=

    Do people increase the likelihood of breaking the gear pins (not teeth) when they switch to solid couplers (no give)? I'm referring to an MPII with 15-20% OD.

    It's only impossible until we do it.

    I've never heard of anyone having problems. The coupler just pulls off, you may need to put a screwdriver behind it and pry it a bit but it should just come right off.

    How are you overdriveing your blower? with the GTP rotor swap I had to stick to the %3 underdrive cause of bad belt slip (new belts).

    10% JS OD and 5% SC pulley OD.

    Project Closure

    Here's a little closure to this thread for those that come across this thread when searching for info on rotor pack swapping. I finally finished the swap. I say finally, b/c when I got into my SC I realized that I should replace the coupler. I was moved to do this b/c the gearshaft had wear grooves in it from the spring in the OEM coupler. After some research, I opted to install the moly-filled coupler from 'Texasthunderbirds.com' (thanks again Wynn!). Attached are a few pics. The red sealant on the flange is anerobic gasket maker Permatex item #51813 (replaces Loctite 518). Flange bolts torqued to 25 ft/lbs. Thanks to all who helped make this project a success. Rotor pack looks and feels (no play) great.

    I imagine you could, but I was able to screw the bolts in by hand each time and noticed no material in the threads from galling, so I didn't use any.

    Well the one I took apart was a real witch!

    I'm pretty sure I broke a cheapie 1/4" socket wrench, if I'm thinking back correctly...

    For that matter, I broke a cheapie autozone puller trying to get the pulley off the SC...
