Crankshaft:
It is overhung type; that means the bearings are on one side, and the crank pin (where connecting
rods are mounted) are on the other side. This unique feature allows usage of single piece
connecting rods which are far more accurate and safer than split con rods. Large bearings in
conjunction with low speeds, allow very long crankshaft life. Replace this part when life of
bearings is over. However, have the crankshaft tested with proper testing equipment in general overhaul periods
and replace it if exceeding the tolerance limits mentioned in the parts.
CONSULT THE NEAREST ALKIN DEALER OR ALKIN FOR REPLACEMENT OR MAINTENANCE
Connecting Rods:
There are three connecting rods which are exactly same for the 1st, 2nd and the 3rd stages on
W32 model. They have bearings mounted on both crankshaft and pistons ends. This allows for
much longer service. However, have the connecting rods tested with proper testing equipment
within general overhaul periods and replace it if exceeding the tolerance limits mentioned in the
parts book.
Note
IN CASE OF CRANKSHAFT REPLACEMENT THE CONNECTING RODS WILL ALSO BE
REPLACED AS THE CRANKSHAFT COMES WITH THE CONNECTING RODS
INSTALLED ON IT. CONSULT THE NEAREST ALKIN DEALER OR ALKIN FOR
REPLACEMENT OR MAINTENANCE
Cylinders:
They are casted separately and are made of high grade casting materials, machined & honed to fined
tolerances for long service life. When worn, they will need replacement. However, have the cylinders
tested with proper testing equipment within general overhaul periods and replace them if exceeding the
tolerance limits mentioned in parts list.

Oil Pressure Switch:
This switch is installed on the crankcase. When the oil pressure drops under 4 Bar, the switch stops the electric
motor and protects the compressor against the damages may arise due to lack of lubrication. This equipment is
standard on all W32 Mariner Electric and W32 Canopy models.

Valve Complete:
Valve Complete consists of valve, valve head and top covers and is located on the cylinders. Valve complete should
be periodically maintained and replaced if required. You can find the replacement times for the valves on the
maintenance table. This replacement times should be strictly followed to keep the compressors running without any
trouble and at its best performance.
CONSULT THE NEAREST ALKIN DEALER OR ALKIN FOR REPLACEMENT OR MAINTENANCE
Oil Pump:
Compressor Lubrication is enabled by a low speed oil pump connected and driven by the crankshaft. The oil pump
takes the oil from crankcase and lubricates the 2nd and 3rd stages by pumping the oil to pass through the
