Other Tractor Starter Rebuild

[bc.gold 3,403]

Prestolite starter brushes totally worn out, new starters are available but with shipping and duty would land on my doorstep for around $500.00.

 

Discovered that I had a CCW starter from a Wisconsin VG4D engine laying on the shelf, brand new 40 years ago, anyhow the field coils and end plate will interchange into my CW rotation starter.

 

Just have to reposition the end plate brush holder to the R position.

I can be so dumb at times, while puzzling over this starter issue totally gaped the fact that I could just turn the brush holder on the Wisconsin engine starter to reverse rotation, then just install my other armature which has the proper Bendix and nose cone to fit the current application.

Most grease monkeys my age know this trick, how to hold the brushes in place and making it easier to install the field brushes.

The R and L stamped into the brush holder have nothing to do with armature rotation, it's how the field coils are wound that change armature rotation.

 

The pig tails of the new brushes are soldered using a 50/50 solder tin lead or a 60/40 both have high heat resistance.

 

For those of use that have an old and hard to find starter, and that old starter has a specially cut shaft you can use a press to remove the shaft from the armature core.

 

If you look closely at the shaft you'll note that the splines that grip the armature core are pressed into one end of the shaft, I pressed this shaft from the commutator end through the core which was unnecessary, it would have been easier to have pressed it through the core from the Bendix end.

Pressed out another shaft from a junk starter, this one destroyed the armature core.

This 12 volt Chrysler starter bolts onto the J.I. Case 310, the Bendix drive from the 6 volt starter was an easy swap, pull the spring forward remove the set screw and replace the drive.

 

The Cryco Bendix didn't even come close in resemblance, once removed it was obvious the armature shafts were the same.

 

This is the starter that Matt had welder the Bendix spring solid, I haven't figured out why he did that, not going to loose sleep over it as its not something i would do.

 

Cobble a starter together from parts, that's my style.
