TBM Flywheel rub

[steve-uk]

anyone ever seen this before

so i intalled my TBM flywheel in my TS SS865 motor.. pic below after install

just opened up my flywheel cover so i can pull the flywheel to get at bendix and found this

looks like it was rubbing on in inside of my flywheel cover.. have only turned over the motor a couple of times

Team Scream uses stock cases and i have a stock flywheel cover...

there is not really any evidence of witness marks on the flywheel cover.. maybe a reall small spot.. but there is all the dust you can see on the flywheel front and back and a very small amount of metal shavings on the back of the flywheel


anyone else seen this before?

i know there are two generations of that flywheel

is this reason for that?

 

[steve-uk]

i believe this is the latest version

 

[junkyardj]

look into that

can we see a pic of the cover?

 

[steve-uk]

i cant find any info on tbms website to even suggest there is a gen one or two

 

[steve-uk]

nothing to see .. but ill snap a pic

 

[steve-uk]

pics of the cover .. only witness marks i can find

I don't think we've seen that before!
I know I true all the cranks before assembly (you wouldn't believe how bad some are brand new out of undamaged Yamaha boxes) so for sure it's not that + it would only rub randomly. I would find out where it's rubbing and grind out the cover or change the stock cover over to a Cold Fusion billet cover as we have use lots of them and no problems like that.

 

[junkyardj]

i have another cover here but it looks as though your flywheel made a home already

 

[SUPERTUNE]

That all it would take to rub off the anodizing.
Did you have both dowel pins in? If so just do what I said.

 

[steve-uk]

im guessing not everyone uses the cold fusion flywheel cover tho?

this is the flywheel cover i pulled off my 04 superjet

it does seem to be rubbing in one area.. the cover is located on the dowels..

i used this same cover with a jetnetics flywheel and msd lightened flywheel

never heard of anyone having issues in stock cases with stock flywheel cover

little frustrating that im now going to have to lay out even more $$ on a AM flywheel cover... so i may hit the cover with a dremel.. but even so...

 

[SurferSmurf]

you should put the cover back on, start the motor and rev that sucker to the top. it will stop rubbing very quick. just my 2 cents.

 

[steve-uk]

thinking of smothering the flywheel with ky......

 

[SUPERTUNE]

Just grind the cover...a 15 min fix and for free if you have a grinder. Just use 1211 sealer on the gasket so you don't have to buy one.

 

[SUPERTUNE]

Use modeling clay...

Did you have the front cover gasket installed when you rotated the engine over?

 

[steve-uk]

Did you have the front cover gasket installed when you rotated the engine over?

yes...

it was ready to go in the water, but i had a bad starter and my new oem one came is so i pulled the motor to swap it out.. while i had the motor out i decided to open up the front cover to check the bendix and this was what o found

 

[steve-uk]

just about to re-install.. i have lost my tbm instructions.. anyone know the flywheel bolt torque

 

[SUPERTUNE]

65 ft-lbs!

Stock is 55ftlbs.
Most builders will tell you 70-75ftlbs.
