Product Overview:
This is a simple brass extruded adapter for the PG71 gearmotor.  The intent of this part is to go over the PG71 output shaft, making the perimeter geometry of the shaft to be 1/2" diameter with a 1/8" machine key.

This sleeve is a tight fit over the PG71 shaft.  It can be held in place by a 3/8" id retaining ring.

Usage and Installation:
There is a tight fit onto the PG71 shaft when installing this adapter, sometimes to the point that the brass will peel away when pushing the adapter onto the shaft.  This will help keep the part in place.  When using the 500 Key Hub (am-0077) or another 1/2" bore, keyed item, we suggest to press in the adapter to the hub first, and then press the hub/adapter assembly onto the PG71 shaft.  When pressing on to the shaft, a bit of brass will peel away, resulting in a snug fit.

Specifications:
  • Material: Brass
  • Outside width: 0.499 inch
  • Length: 0.75 inch
  • Key: 1/8x1/8 inch
  • Bore: 10mm (0.394 inch)
  • Weight: 0.05 pound

Avoid this February 12, 2014
Reviewer: R.A.D. from Windsor, On  
Problem is the key that fits into the motor side is not square.. it simply does not fit.
Once you mash it on, it slips like crazy, and being made of brass, it shears off with ease.
This does not work other than for the lightest duty applications, and not without some major adjustments, and frustration.

Don't waste your money January 28, 2014
Reviewer: John Keyzer from Like Zurich, IL  
Like many other teams we purchased these hoping they would be a solution to an Andy Mark created problem, however we had no such luck. Shaft key way was undersized and adapter was oversized. We pressed the adapter on, assembled our mechanism and tested. The brass was so soft that under load it gave way causing a ton of backlash.

This is an Andy Mark created problem because a 4mm key in a 10mm shaft is not a standard size. You cannot buy a broach/ bushing to create a corresponding 4mm key in a part. The only answer is this subpar adapter, or to find a sponsor with a wire EDM machine to cut some proper sized steel adapters.

Please Andy Mark either redesign the output shafts on the wonderful planetary boxes or sell a steel wire EDM cut adapter.
