From 1998
Fit the nylon sleeve over the driven gear and offer up to the extension shaft. Install
the three long bolts, washers and spacers, two per bolt. Finger tighten the three
bolts, adjust the position of the pump and bracket assembly in relation to the
extension shaft, aligning the couplings until the nylon sleeve moves on the
teeth/splines with end float.
Tighten the retaining bolts and check the sleeve is still free to move. Refit the
coupling guard. Remove the plugs and reconnect the hydraulic hoses, top up the
hydraulic oil levels. Mop up any oil spills.
415 Volt 3PH Electric Motor
Note, Depending on the model of motor fitted (from March 2002) the motor may be
wired either Direct On Line or Star Delta.
The motors run at approximately 1420/1470 rpm and rotate Clockwise.
This reverses the drum rotation and consequently the drum requires different drum
blades (same as 200T diesel). To accommodate the reduction in rpm at the motor
and to prevent the characteristics of chain drives damaging the motor the
countershaft chainwheel and engine drive chain are replaced by a “V” belt and “V”
drive pulley.
The motor is also mounted differently in that it is bolted to a height adjustable
bedplate to allow for belt tensioning.
The motors are also twin shafts, i.e. a driveshaft at end in order to provide a power
take off for the hydraulic pump drive.
Similar to the hand start diesel engine if a dragline is fitted power for the solenoids
and switches is provided via a 12-volt automotive dynamo. Drive being taken from
the pump drive p.t.o. shaft.
The contactor enclosure is fitted in side the engine housing usually to the L/H side of
the housing whilst a key lockable ‘emergency’ stop button is fitted to the exterior of
the housing again on the left hand side just above the hydraulic tank housing.
Note, locking off the stop button prevents any un-authorised person from starting the
equipment BUT does not isolate the electricity supply, before carrying out any work
on the motor, contactor or enclosure isolate the supply at the main distribution board
and attach a suitable ‘locked out’ tag to prevent the supply being inadvertently re-
connected.
Belt Drive Pulley Removal/Replacement
The drive pulley is mounted onto the motor extension shaft, and is secured with a
feather key and grubscrew.
