Bent Rear Shock
« on: October 12, 2014, 09:04:18 AM »
I'm taking apart a 75' CB550F and noticed that the left rear shock is slightly bent. Is there anything I can do to fix this or should I just buy a new set? Thanks.

the bent shock


the right unbent shock for comparison

Assuming they are 35 years old, I'd be shopping for a set of Hagons.

Looks like the damper rod is straight but the spring is out? Hard to tell. Either way, something is amiss and Stev-o is on the money I reckon.

I'd want to be sure the rod is actually bent. Spring could not be seated perfectly centered or can bow a little either side I suppose as nothing keeps it centered.

For giggles again did the bike ever have shock lowering brackets on the swinger ? Those can put some undue stress on shocks with the new angle.

I think Cal is right on. You notice one spring looks more compressed

PS- Honda did not use a big lock washer on the head of the lower mount bolt  ;)
