Want to do better than a chromey
aftermarket-part-that-will-eventually-rust axle adjuster?
Yes I wanted to get rid of the stock
adjusters, and chrome bolts these days are really on my bad side. I've
been replacing chrome bolts left and right due to the fact they are
rusting like there is no tomorrow. (See SS Bolt Mods)
I replaced my axle adjusters with
Stainless Steel bolts-nuts-acorn nuts from a hardware store.
3" x 3/8" SS bolts
(all thread to the head)
3/8" SS nuts
3/8" SS acorn nuts
Hack off the heads of the bolts. I use a
side grinder with a metal cut off wheel for everything. If you don't
have a mechanical way off cutting through steel, this mod is not for
Take the bolts and slightly angle the end that will make contact
with the axle spacer notch. The stock bolts are angled more than they
need to be, and the axle spacers may vary from model to model; I won't
go into detail. I did not angle mine too much. I chucked them into a
drill press and contoured a slight angle on them.
Take a steel punch and knock a few dimples into the threads where
the acorn nut will pass over. The idea here is to freeze the acorn nut
onto the bolt. Apply a couple drops of RED thread lock on the threads
where the acorn nut will pass over. Apply acorn nut to bolt and torque
down until it torques no more - with nominal leverage of course. Once
the thread lock sets up, forget about ever taking the acorn nut off.
Even if you could , throw it away as the threads in the nut are now
ruined due to the dimples.
Install the new adjusters into the swingarm, carefully
repositioning and calibrating to service manual specs. This is
critical for proper belt tension and tire tracking.
