From 1998
If a dragline or batchweigher is to be installed information on the control block,
solenoid or bleed valve can be found later in this manual as can a detailed
description of the hydraulic system.
Engine TS/TR1 Hand Start
“CE” marked machines are fitted with an extended engine oil drainpipe and ‘anti-kick
back starting handles’ in order to comply with local legislation. For information on the
starting handles refer to the engine operators handbook or engine workshop manual.
For details on engine services or overhauls, changing engine oils, filters and bleeding
the fuel system refer to the engine operator’s handbook or engine workshop manual.
Note, the engine is set to run at 1500 rpm and rotates Anti-clockwise at the flywheel
end.
Drive Sprocket Removal/Replacement
The drive sprocket is mounted onto flywheel end extension shaft, approximately
40mm from the end of the shaft and is secured with a gib head key and grubscrew.
To remove the sprocket, first remove the engine housing closing and top plate,
exhaust extension pipe, upper and lower chain guard, drive chain and engine
housing support bracket, If a dragline option is fitted remove the dynamo drive belt.
Remove the four bolts securing the engine to the bed and slide the engine backward
allowing access to the extension shaft. Turn the flywheel until the key and grubscrew
are visible. Mark the position of the sprocket on the shaft and remove the grubscrew
and key, tapping the sprocket backward on the shaft away from the key will assist in
the removal of the key.
Smear the bore of the new sprocket with anti-seize compound and slide onto the
shaft upto the mark made earlier. Fit the key and grubscrew, due to manufacturing
differences it may be necessary to fit a new key. Reposition the engine, refit the bolts
and drive chain, if a dragline is fitted slip the dynamo drive belt over the shaft and
sprocket onto the pulley before fitting the chain, confirm the chain is correctly aligned
and check the chain tension.
The chain tension is correct when the chain deflects approximately 5mm about the
centre line, the deflection should be checked midway between the lower sprocket and
upper chainwheel.
Add or subtract shims below the engine to correctly tension the chain.
A chain running too tight will cause starting problems and the increased loadings will
increase the rate of wear on the chain and sprocket and may also damage the
