Spinner II Troubleshooting
Centrifuge removes too little dirt.
Check for Proper Operation
Warm up the engine and then bring the engine to normal speed for one minute and immediately shut it
down. If the Spinner II unit is working correctly the turbine can be heard spinning. As with any high-
speed device, it may go through momentary periods of vibration as it passes through critical speeds
while slowing to a stop. This is normal. If the turbine is not spinning or if vibration is severe or continu-
ous at all speeds, an error may have been made in assembly. Repeat steps 1 to 10, paying special atten-
tion to the proper seating of the baffle/screen (M), the bowl seal (N) (Step 6), and the control mechanism
(Step 9). If vibration persists, substitute a different centrifuge turbine assembly (D).
If the turbine is spinning properly, the centrifuge is doing its job of removing harmful abrasive dirt re-
gardless of the amount of deposit found in the bowl. The visible deposit is largely soot and its thickness
will vary from 1⁄16" to completely full depending on oil type, oil change interval, engine type and condi -
tion, and operating conditions. Oil additive package design will affect soot size and thus the amount of
carbon and soot collected in the bowl.
Control air valve problems.
Float valve flows air constantly or not at all, up or down.
Air tank bleeds down overnight.
The valve cores on the Spinner II air control are special low operating
force types with green Viton® seals made to withstand high temperatures.
NEVER replace with tire valve cores.
Check Valve (Step 9)
Most air control problems can be repaired without dismounting the centrifuge by renewing the air valve
cartridge (Q), making certain that air valve cartridge seal (R) is in place. A cartridge installed without the
seal will be damaged and will leak continuously. If the float mechanism is worn or broken, the centrifuge
must be disassembled and repaired with control float mechanism repair kit. Instructions are contained in
the kit.
Oil leaks.
Cover Seal
Remove cover (A) and cover seal (C). Clean seal grooves in housing and mating surface on cover. Install
a new cover seal (B) in the housing groove, replace cover (A), position clamp (B) uniformly over cover
and housing flanges, and tighten clamp handle securely by hand pressure only .
