1-8 Roller Assembly Inspection
1) The pressure roller {pos. 48, #18287}
usually dislodges when removing the top
casing cover. If necessary, use the Blocstop
tool {#20887} to remove it along with the
driving roller {pos. 50, #18237} (Figure 139).
2) Remove the (2) adjusting washers {pos. 11,
#9826} as shown in Figure 140.
3) Inspect both rollers for excessive wear or flat
spots (See Figure 141). Even if they show no
visible wear the inside of the groove must still
be measured with a caliper. The nominal
diameter is 27mm. If the diameter is less
than 25mm (1") the rollers must be replaced.
If one roller needs replacement, they both
must be replaced.
4) Inspect the pressure spring {pos. 58,
#37235}, spacer {pos. 70,
#38555} and guide tube {pos. 59, #36296} for
damage or wear (See Figures 142 & 143).

NOTE:
If the guide tube is worn and the end of it has
mushroomed, it must be replaced to prevent
interference with the roller.
