Triumph Oil Filter Mount installation

The Norton filter adapter is then bolted to the rear piece, oil hoses are added, an oil filter is screwed into place, and the assembly is offered to the bike. With the bike supported by straps up on a lift, it will be easy to loosely mount the front clamp section in place and slide the whole assembly up the frame tube. In order to miss the center stand, the filter will need to be as high as possible without the grease nipple striking the top of the adapter. As it ends up, there is “sweet spot” where both the nipple and the stand miss the oil filter by about an 1/8 inch. Tighten the mount down when you find that place. I found that the Norton filter adapter is best plumbed using 5/16 ID black neoprene fuel hose. The spigots on the adapter are 3/8 inch, but it is better to stretch the hose over these that to use easier fitting 3/8 ID hose and then try to shrink it onto the Triumph’s smaller metal oil lines. There will simply be fewer oil leaks using the smaller hose. Be sure that you plumb the filter into the oil line that returns engine oil back to the oil tank. The Triumph oil pump cannot be counted on to create enough vacuum to suction highly viscous motor oil through a very fine filter during cool temperatures. Trying to place the filter on the oil line feeding the engine will quickly result in massive engine damage. It is always better to have the oil pump pushing oil through the filter, and the only way to have RF Whatley, Suwanee, GA 5 Jan 2008 that is to use the return oil line. On all “unit-construction” Triumph engines, the rear-most oil port is the engine oil return. Other Notes • It is generally considered that adding an oil filter will at least quadruple the life of a British motorcycle engine. These motors, which were for the most part perfected in the 1950′s, were designed to run on the older non-detergent oils. In the original design, the oil tank was the oil filter since all particulate debris in the oil settled to the bottom of the oil tank as sediment. All modern engine oils are high-detergent and tend to inhibit the formation of sediment. Therefore most of the fine abrasive in the engine oil continues to circulate unless a filter is added.
