OK…. I thought I would share how this thing got blown apart and put back together…..

First, using my $5 Harbor Freight Deadblow, whack the Chuck to remove it!

Then, Loosen the retaining nuts on the crank shaft return spring

Nuts Removed

Here is the return spring, cover and backing plate

The assembly containing the hollow crank and the spindle will fall out once you remove the actual crank arm (Forgot to get a pic of this…... OOOPS)

Remove the C-Clip ring from the spindle shaft so you can remove it from the hollow crank…. try not to break it like I did

As you can see, this is NOT a morse taper! The spindle rides in two sealed bearings which in turn ride inside the hollow crank body.

I’m going to splurge and spend $30 on a dial indicator at HarborFreight. Evidently they are decent enough quality. I should be able to measure the runout on the spindle shaft itself. I don’t have a “calibrated rod” to put into the chuck, but This should tell me if the shaft itself is bent and how bad.

I ended up putting everything back together after cleaning it really well with WD-40. Its much smoother and the wobble is no where near as noticeable. But its not perfect and that will drive me bonkers.
