[edit] Grey Motor Bypass Oil Filter Fitment:

[edit] Description:

A NASCO accessory Oil Filter was available for Grey Motors. It was not a Full Flow Filter as used on Red and later Engines.

Oil was bled from the Oil Pressure Switch tap via a T- Piece and flowed into the Filter.

Output Oil from the Filter went straight back into the Sump via a Bolt Hole Tap Point on the Driver's side of the Crankcase.

[edit] Original Availability:

The Bypass Oil Filter was available as a NASCO accessory from as early as 1950.

In DR terry's book it says the engine was designed for a accessory oil filter(bypass type)so i would say dealer fitted from the start if you wanted it?

[edit] Mounting:

The Mounting Bracket screws onto the Side Plate between Cylinders 2 and 3.

A Horseshoe Bracket holds the Filter to the Mounting Bracket. Each end of the Horseshoe Bracket has a Nut and Washer which are tightened

to hold the Filter in place.

[edit] Input:

It simply tapped into the Oil Pressure Switch hole and used a T Piece to allow Oil to flow into it.

[edit] Output:

The Output screwed into a Bolt Hole in the side of the Crankcase near the Fuel Pump.

The Input connection taps into a T Piece where the Oil Pressure Switch is installed. Click to Enlargen. Photo by StaccyS.	The Output connection taps into the Bolt Hole in the Crankcase.

Hi EK KAI.

The grey motors had no oil filter fitted as standard. There were however several accessory filter kits made available over the years. From memory there were 3 brands, AC, Fram & Ryco. If you have 1 of these kits fitted, you can look up the Ryco listings to find out which filter cartridge you need.
