Brake pivot ready to install.

You will notice a yellow shim spacer on the bushing.

I punched that out of plastic shim stock to take all slop out of the pivot but still allow it to rotate freely.

A grade 5 bolt was used instead of stainless steel because I figured strength was more important than looks for this.

 

Brake pivot installed.

Brake drum ready to install.

 

Brake shaft coated with never seize.

 

Brake drum retaining bolt with blue loctite applied.

Note the parts manual says to use 1" bolt but I installed a 1-1/4" since there was plenty of depth available in the shaft for it.

Do you ream that pedal or is it sized from the factory?

This pedal is from a 520H which comes with bushing from the factory.

The factory bushings are very short but these 0.5" long ones fit without issue.

I really dislike that style of spool valve. They are prone to keeping a little air in them and can have quite a squeal until the bubble gets worked out. 
 

My 523 uses that valve and it still squeals a little. Not as bad as when I first hooked it up, but it’s still there.
