Plus re-sizing worn original Ford bushings.
- Burnishing tool print
The first tool Sized too small. There was more spring back in the bushing. About .002
Required a second tool +.002 to get to .682 finished. Thats good for .678" pins.
I may polish a bit more to maintain a consistent .004" clearance.
.005 is still acceptable in my book for a .677 pin.
- Burnishing and sizing tools
#2 tool larger to allow for the spring back. The grey color is from black graphite spray lube.
# 2 is more polished from sanding & polishing to get the size down for .004" clearance.
Tool #3 Recognize?? Made to squish the bushing once back in the gear to decrease the ID back smaller to take the new sizing.
- Finished triple gear
This is a resized original bushing.
Note under the bushing flange is a .010" thich shim washer To get the thickness back up to recut the .010 height.
Note the counter sunk edge to get the oil to the 2 oil groves. The 2 grove openings were also kissed with an 1/8" die grinder bit.
A concern I had was the resulting centering of the bushing to the gear outside radius & pitch radius.
I found that the gear has a measurable off center hole of .001". Thats before & after the procedures performed.
Very acceptable, better than I thought it would be.
So I now have the tooling to do the best possible rebuild on the tripple gear bushings.
P.S. I have the great minds on this forum to thank for all this.
