6. Insert the shaft adapter so it engages the drive pin.
7. Next, insert the spring, spring guide and oil pump
assembly. The pin on the oil pump must align with
the slot in the shaft adapter.
8. Install the pump cover so the pin on the case
is in the opening on the oil pump assembly as
shown in figure 4.8. When you are sure the pin is
properly aligned, install the cover bolts finger tight.
If alignment is correct, the pump cover will mount
flush to the bearing carrier. If it does not, re-check
the pin alignment.
9. Tighten the bolts in an alternating sequence. See
section 2.3 for directions on oil pressure adjustment.
10. Finally, rotate the crankshaft by hand to ensure
smooth operation. Then rotate it in opposite
directions, listening for a click, which indicates
proper alignment of the oil pump’s pins and slots.
Chapter 5—Extended Storage
Procedures
Following a few simple procedures will greatly minimize
the risk of the unit becoming corroded and damaged.
Corken recommends the following precautions to protect
the compressor during storage:
1. Drain the crankcase oil and refill with rust inhibiting oil.
2. Operate for a few minutes while fogging oil into the
compressor suction.
3. Relieve V-belt tension.
4. Plug all openings to prevent entry of insects and
moisture. (The cylinders may also be protected by the
use of a vapor phase inhibitor, silica gel, or dry nitrogen
gas. If the silica gel is used, hang a tag on the unit
indicating that it must be removed before start-up.)
5. Store in a dry area and off the ground if possible.
6. Rotate the flywheel every two weeks if possible.
