Never go over 65 with the TBM!
70-75 is ok for new crankbolts and stock flywheels.

Out of curiosity, what do you torque the MSD TL flywheels to?
I've seen you advise 80 ftlbs in the past.

EDIT: If I remember correctly, ATP calls for 75 on their Flame stuff. What is the difference due to in the different flywheels?

It would almost seem like the woodruff key wasn't sitting in it's place correctly? I've seen both the old and the new TBM flywheels used on different engines with stock cases and covers with no problems. I'd be questioning weather or not the flywheel is seated properly.

I was just about to say that Watty, Steve it may be an idea to put some engineers dye in the flywheel taper then put it on the crank to see if its seating properly.

thanks guys

i have put it back together, making doubly sure that everything is in place correctly

im going to take it for a rip today and then ill pull the cover off again to see whats what

it feels like its seating properly, but i guess if there was a manufacturing defect then i wouldnt find that unless i did the above, but the fact that there are not witness marks to speak of on the cover id be suprised at this

what i could do is run a DTi across the front face as it rotates to see what variance there is

my only other explaination for this could be that the gasket got snagged on installation, of as sitting slightly inside the cover (am gasket not oem - im starting to learn my lesson on certain am parts) and rubbed on the flywheel rubbing off the anodising... i dont think this happend but its my only other explaination i can come up with

woodruff key - check
bolt to torque - check
dowles - check
gasket - check

braaaaap - going to check :veryhappy:

I am wondering that myself after reading SuperTunes post. Last season I had an issue with my TL. On landings my ski would bog out, turned out one pickup wire was contacting the ring gear (burned through the insulation) causing a failure to fire on one cylinder. I am using the supplied MSD grommets. I also noticed this go around my bendix was rubbing the ring gear ever so slightly at idle.

I was thinking the flywheel could be pressed on to deep at the stock torque value.

When you use MSD TL systems you have to sleeve the pickup wires under the stator plate and string the wires in pairs in the back two holes in the MSD cover grommet, if use the front holes in the MSD grommet you'll chew them up on the flywheel ring gear as you did.

Well thats no good. I figured you would use each hole for each wire. So I will need to run each pair of wires through one hole and leave the two up front plugged or sealed off. I wish that would have been in the directions MSD supplied.

Thanks clearing that up.

Good grief Shifty! Don't even consider using that pos MSD grommet! That weird plastic will shrink over time and let water enter ( I saved one for show and tell ). I have used the grommets from junk stators. One wire per hole!
