Some info I thought I'd best share with those running
my sealed bearing conversion,
when checking my son's 4500 over I noticed some play at the right hand pivot,first thought the Ti M8 X 25 flanged bolt had come loose,turned out the head had sheared off and was just hanging in there,
I don't know wheather this is all because of material failure, faulty manufacture,over torqued (20lbs ft) or the fact
over the years it been removed and refitted many times (must be 2 to 3 years old now),
I've now replaced the Ti bolt with an M8 X 20 grade 8.8 steel bolt
with a standard flat washer liberally coated with anti sieze and torqued to 20lbs ft,
just thought I'd pass this on, the good news is the through shaft, s/arm, bearings suffered no damage despite running loose for how long I don't know.

Drive side you say???? Jr. must have some burly legs.
So even if the other side broke too, it would still not fall apart as the bearings are still clamped in the swingarm and holding the shaft in the frame.
I say, Good Show!
