Gearwheel Bilge Pump
The pump is driven by a V -belt (L T 28) on the outermost track of the flywheel
drive pulley. The V -belt is tightened by slaékening screw (1) and tuming the whole
pump. Re-tighten the screw securely.
Engaging anddisengaging (handle 5) must onIy be performed at low engine speeds
to avoid wear on the driving pulley or damage to the drive key.
Ensure that the pump is engaged or disengaged fully.
The drive key (2) can be replaced by unscrewing the set screw (3) with a 3/8" socket
spanner. Anew drive keycanbe made from 1/4" x 1/4" x34 mm mild steel.
If the pump is not working properly or if it needs excessive priming, tros may be a:n
indication of intemal wear causing leakage between suction and pressure sides of
~ the pump. In tros case the end clearances of the gearwheels must be reduced by
~ filing the pump housing flangeuntil flush with the gearwheels.
