Title: 1959 C15 rear shocks
Post by: rhyatt on 20 Sep, 2024, 17:42
I have just purchased a pair of Wassell WW60077 open spring shocks , but sadly they do not fit.
apart from being 11.9" long as oppsed to the original 10.9" the lower bush ID does not slide over the swinging arm spigot - even a quick spruce with emery will not do the trick.
the old girling unit glides on and off and there are no burrs or damage to the spigot
Is this a case of aftermarket parts not being correct or am I unlucky and a replacement pair will glide onto the bike !!!!!
just had a closer look and there is very little clearance between the swinging arm and the frame outrigger that supports the pillion footrests , so a longer unit may push the swing arm too far downwards to foul the pillion support.

Even if the Shockers fit, being an inch longer that will make the steering  steeper so alter slightly the handling.

Yes indeed,
I've been looking closer at these new units, I have a 1/2" reamer which is the dimension  of the swing arm pin.
It naturally glides through the old unit , but will not enter the brand new bottom bush
.it's so frustrating the quality of modern replacements.
I'll have to take the reamer with me when I take them back I suppose
