I have installed the filter in the tool box of plunger and rigid bikes.
I make the filter head to suit a standard (and compact) Ryco spin-on filter.
Then I use Swagelock stainless steel compression fittings, and 8mm stainless tubing, to solid plumb the filter to two Swagelock bulkhead fittings fitted in the lower front face of the tool box.
The toolbox was painted AFTER mounting the filter, and drilling holes for the bulkhead.
I use hoses from swinging arm A10's, and shorten them. I machine aluminium ferrules and re-crimp them on the shortened hose.
I also make an extended hose end out of 8mm tube for the top fitting, machine barbs on the tube, and custom bend (to clear oil tank filter) before crimping on the shortened hose (as per the second last photo; Gavin's bike).
To get the filtered oil back into the oil tank, I machine a replacement fitting which screws into the tank. It must have a 30 degree taper, to seal on the banjo for the rocker oil bleed, and 1/4" BSP thread (with internal 30 degree tapered seat for the hose end to seal on). Then I pass the hose behind and around the frame down tube, across the top of the gearbox, and using a 90 degree bend from the standard A10 hose, onto the fitting.
Some of the pics show 45 degree 1/4" bsp elbows welded into the toolbox. this was my first layout; latest arrangements use the swagelock bulkheads. The lower bulkhead requires the internal taper to be machined to match the taper in the 1/4" BSP hose end.
This is the filter fitted to Josh's bike
Here is a filter for Gavin's bike, being temporarily set up on one of mine.
I also have an arrangement for the swing arm bikes, but's that's another story!
