lt1bird Posted January 4, 2009 Report Posted January 4, 2009 I have a stroker crank, went to put the flywheel on and the flywheel key does not fit the crank. The key is 5mm wide and the crank keyway is about 4.98mm wide... this is not supose to be a press fit correct..... What should I do? I could probably sand the key down a bit but is this BS common?? Thanks Quote
98_shee Posted January 4, 2009 Report Posted January 4, 2009 It should fit a little tight, can you tap it in the crank? Quote
lt1bird Posted January 4, 2009 Author Report Posted January 4, 2009 I dont think it will tap in too easy..... it does not want to go in a little. I have 2 keys...one stock, one aftermarket..they both do not fit... Quote
RUDEDAWG Posted January 4, 2009 Report Posted January 4, 2009 I had to tap mine in, it took a little effort but I got it in. Remember to install it paralell to the crankshaft centerline and not paralell to the taper. Quote
lt1bird Posted January 4, 2009 Author Report Posted January 4, 2009 was it a factory yamaha key? I see that thiers has a small protursion on the side of the key....this is meant to keep the keyway in the pocket so it will take a little tapping....the aftermarket key does not have it.... Quote
lt1bird Posted January 4, 2009 Author Report Posted January 4, 2009 well I cleaned up the key with a little 1200 grit sand paper and taped that sucker right on. Thanks! Quote
XxMeltIcexX Posted January 4, 2009 Report Posted January 4, 2009 well I cleaned up the key with a little 1200 grit sand paper and taped that sucker right on. Thanks! Ya, I make my own keys by grinding them down, no problem there. Quote
FireHead Posted January 4, 2009 Report Posted January 4, 2009 You usually have to tap them in a bit........... An OEM Yamaha key is probably all you want to use. There is so much variance in generic woodruff keys that it's not worth trying something else............ :geek: Quote
