Topic: Swing Arm Test?

[wedoo2]

Working on my 74 550 restoration and I was wondering if there was a way to tell if the swing arm needs a refurb as well.  The arm moves up and down freely without any noticeable hitches.  It does not move completely free, more like it is on there tight.  I think ok.  What say you?

have you checked sideways or for any possible wobble?

According to the FSM, the bushing ID should be between 21.44 mm (new) to 21.8 mm (service limit) page 139 and the measurement process is shown on page 82. 

If your bike has less than 30,000 miles, it is likely to be OK.  But I would suggest removing the pivot bolt, clean everything, check bolt & swing arm bushings for excessive wear.  Reassemble with appropriate lube as per FSM.  New bushings are pretty inexpensive at partsnmore.com, I just happened to see them the other day, though I am not sure which years they have in stock.  Make sure you can get replacements for your year/model before removing your old bushings.

Push the swingarm side to side.  That is where you will find evidence of wear.  If there is any shifting at all, then you will notice it when riding.

What is a FSM? F***ing Shop Manual?I want a copy. Side to side on the centerstand is the way to measure. also if it's ridable, watch the swing arm when you shift and accellerate, you'll see the sw move if theirs a problem. it's how i knew mine needed some attention.

More people believe the FSM than in  the manual.
