Dismantling
Remove brackets (38).
To remove the pulley (32) release the locking tab of the taper lock nut (31) and
unscrew the locknut approximately two turns. Place supporting wedges between the
pulley and the vibrator case end plate (30). Position a short length of tube over the
end of the shaft so that it bears against the taperlock nut. Give the tube a sharp tap
with a hammer to release the taper lock and remove pulley and taper lock from shaft.
Unscrew the cap head screws retaining the end plate and remove the end plates.
If it is felt that the bearings are not worn, but need regreasing, use Castrol BM2 or an
equivalent grease. Half fill the bearings and fully fill the end caps. If the bearings are
to be renewed, continue dismantling as follows.
Strike the long end of the vibrator spindle with a copper faced mallet. This will drive
out the vibrator spindle and far bearing. Remove the near bearing by striking it with a
suitable drift inserted from the far end.
Reassembly
Grease the bearings as described above
First place a bearing shield (64) over the short end of the vibrator spindle with
grooved side facing outwards and then press on a bearing. Apply a thin layer of
grease to the outside of the bearing and to the bearing housing. Offer the bearing,
spindle and bearing shield to the housing and force home using copper faced mallet
or press. Fasten the rear cover (36) into position using cap head screws (33)
Place a bearing shield over the end of the shaft. Lightly grease the inner and outer
surfaces of the second bearing and also the shaft and housing. Force the bearing
onto the shaft and into the housing using a suitable tubular drift and copper faced
mallet. Renew the seal in the end plate and refit end plate.
NOTE: Some older base plates might not have a shoulder in the bearing housing.
For these applications only Nilos ring, Part No. W81053 may be used. These fit on
the shaft between shoulder and bearing. If they are not available, pre lubricated
bearings; Part No. W81020 with shields may be fitted. For housings that do have a
shoulder, bearing shield, Part No. W51788 should be used.
Replace the bottom pulley and taper lock, but do not tighten until the engine is in
position and pulley adjustment can be checked.
