Caution: Do not use excessive torque.
5 Hold the spacer in position and engage the
setscrew fully into the threads in the pin.
6 Put the spacer into position centrally over the pin
and tighten the nut onto the spacer. Continue to
tighten the nut and pull the pin through the spacer.
Withdraw the pin enough to pull the pin out of the
bearing cap with pliers.
7 Put a suitable adaptor on the small diameter of the
idler shaft and press the idler shaft out of the bearing
cap.
Optional method to remove the idler shaft
1 This method to remove the pin from the idler shaft
must only be used if the pin cannot be removed by the
earlier method.
Make a drill guide (A) to the dimensions given below:
A1 8,3 mm (0.327 in)
A2 20,0 mm (0.984 in)
A3 1,0 mm (0.039 in)
A4 16,1/16,4 mm (0.633/0.646 in)
A5 6,9 x 22 mm (0.272 x 0.866 in) diameter
hole for 5/16-24 UNF x 18 mm thread
A6 36,0 mm (1.42 in)
A7 6,5/6,6 mm (0.256/0.260 in) diameter hole,
countersink 9,0 mm x 900 included
A8 31,75 mm (1.250 in)
A9 15,9 mm (0.626 in)
2 Put the drill guide (B1) into position in the setscrew
hole on the opposite side of the bearing cap to the pin
(B2). Ensure that the countersink in the guide faces to
the outside and that the edge of the guide is aligned
with the front edge of the bearing cap. Use a 5/16
UNF setscrew (B3) and a plain washer (B4) to retain
the guide in position.
3 Drill a 6,35 mm (0.25 in) diameter hole in the
bearing cap 47,0 mm (1.85 in) deep.
4 Remove the drill and the drill guide.
5 Insert a suitable drift into the hole in the bearing cap
and drive out the pin.
6 Put a suitable adaptor on the small diameter of the
idler shaft and press the idler shaft out of the bearing
cap.
