After bushings have been installed, check fit of distributor
shaft in bushings. Size bushings if necessary to obtain .008 -
.038 mm (.0003 - .0015 inch) running clearance.
The oilite bushings should not be reamed.

tachometer drive, use burnisher tool SE-1955-2.
For distributors with tachometer drive, use
burnisher tool SE-2779.
If shaft passes through upper bushing but binds in
lower bushing, burnish lower bushing. Burnish lower
bushing only. If shaft does not pass through or binds
in upper bushing, burnish upper bushing first and
repeat check for shaft fit. Then burnish lower
bushing, if needed.
To burnish bushings:
Place flat end of burnisher in a vise. Coat
burnisher with SAE-20 engine oil.
Burnish upper bushing by carefully placing
distributor housing on burnisher and rotating
the housing clockwise using light pressure
until tool passes through bushing (Figure 33).
Burnish lower bushing per step "b" above.
