Is this the factory crankshaft?
Well the thing is it puts the belt up against the new altenator bracket when it over exerts it. In otherwords the belt tensioner won't return to its orginal side, it stays locked up against this piece..b16sir1991 said:The couple JRSC kits we have done max out the belt tensioner also.
Looks like I am not the only 02 with this problem...b16sir1991 said:None of the ones we have done did that? Thats very strange.
I am pretty sure it is the new bracket as I bought the kit brand new through justing but from JR just a few weeks ago. In fact Jackson Racing was out of them and had to wait on new ones to come in.justjeffrey said:Now this is going to funk things up - JR used two different alternator brackets. The one you have is probably the old one. See how in the picture the tensioner bolt is tucked high up by the metal idler pulley? Well if yours is not tucked up that high then you have an old alternator bracket/kit and need to go with the OLD BRACKET OLD BELT SIZE method and disregard all the new Ford racing BBK stuff because the BBK was not even around yet when that bracket was in use. The new bracket was introduced to fix the "start up squeal problem.
