Description
This is the steel colar required to use poly lip seal style crank seals. There are two sleeves, one for the drive end (this one) which is 21/32″ long. And one for flywheel end which is 1/2″ long (see separate listing).
Note that the flywheel collet (aka drive cone) is also 3/16″ shorter with the conversion collars and lip seals (Stuart part number 14751). The original part 946 has the longer flange at the aft end.
