DIY nylon bushings w/ common tools

There was a lot of play in the gear stick of my '71 220D even after installing bushings for the link rod down under, so I disassembled the shift housing and discovered a few remains of 2 bushings between the housing and the horizontal rod connected to the lever (1). Autohauz didn't carry such bushings, which I measured to be OD 21mm, ID 16mm. So I set out to make them... without a lathe.

I got 2 nylon spacers (1" x 1/2" x 3/8") at the hardware store (for $1.15). The 1/2" ID fit perfectly on a Dremel sanding drum (2).

Fitting the attachment in a drill, I used a bench grinder to get the outside diameter down to fit into the housing (21mm). Then removing the axle but leaving the drum, it provided an ideal guide for a 5/8" spade bit, which, thankfully is 16mm. It drilled beautifully until the spades broke through, so a Dremel grinding attachment finished it up. The third pic is before and after.

And the unit reassembled with the new bushing just visible between the rod and housing. (4).

That's a very nice piece of work you did. I have a lathe and a milling machine for jobs like that so I'm really impressed with your creative use of simple tools to "get 'er done".

It's an example of the fact that we really don't need to rely on expensive "professionals" and "genuine" parts to get an excellent outcome.
