SPINNER II OIL FILTER
The Spinner II model 976 is a centrifugal type oil filter. It works by receiving oil from the primary
filter (the primary filter is the first filter that the oil encounters in the filter loop) and sends the oil down
through a cylinder or bowl that spins at a high rate of speed driven by an air turbine. This pushes the par-
ticles in the oil to the sides of the bowl where they stick, and allows the clean oil to drain out the bottom
and back to the engine. Spinner II oil filters are built to be completely reusable, unlike a filament type
filter.
Like any other filter, the Spinner II requires regular inspection and cleaning. An added advantage with
the Spinner filter is that it can indicate an engine problem by the appearance of the dirt when it is being
cleaned. The dirt in the bowl should be caked or chalk like and crumble when removed. If the dirt ap-
pears soft and mushy, this indicates that the engine oil is contaminated with coolant and that inspection
of the head gaskets and checking for other internal component failures is required. Check and clean the
Spinner II filter at every oil change.
Spinner II Service Instructions
Clean and service the Spinner II filter (Figure 3- 5) as follows:
If the coach has been in operation long enough to reach normal operating
temperatures (180°F to 190°F), use extreme caution when removing the
engine pan drain plug and filters as serious burns can result.
1. Shut off the engine and allow the centrifuge turbine assembly (D) to come to a complete stop.
2. Loosen the handle on clamp (B), disengage T-bolt and remove the cover (A), using a coin in the
gap to separate the cover from housing.
3. Partially withdraw the centrifuge turbine assembly (D) from the housing (E) and allow oil to
drain from nozzles (O) before removing the assembly completely. Hold the centrifuge turbine
assembly in one hand and loosen the knurled bowl nut (H) several turns until the face of the nut
projects beyond the bronze bushing face. Carefully separate the centrifuge bowl (K) from the
turbine body (U) by striking the face of the nut (H) with the palm of one hand while holding
the bowl in the other. Do not strike the nut or the bushing with or against a hard surface or
damage will result. Finish removing the nut and then remove the bowl and baffle/screen (M).
4. Simply replace the dirty centrifuge bowl with a new one, or carefully remove the dirt cake from
the bowl (K) using a wooden spatula or other non-damaging tool. Wipe out the bowl with sol -
vent.
Note: To save time in cleaning, an optional die-cut Bristol paper insert (L) is available as a ser-
vice part and may be installed to allow the compressed cake to be removed quickly.
