A10 oil filter
« on: 21.04. 2009 23:13 »
Have found mention of an "oil filter" in the base of the scavenge pump case, but can not find a part number in the Draganfly, BSA or SRM manuals, is this an urban myth or has a part number ?.

Josh, the filter is attached to the sump plate, part number 67-1285. It is soldered in position.
If yours is damaged, you can remove the gauze screen and fit a filter plate from an A65 between the sump plate and crankcase.

Josh,

Take a look here:

http://www.srm-engineering.com/catalogue/index.php?target=products&product_id=34

SRM will sell you the gauze filter without the plate. I like theirs because it fits well. I bought one from another source and the diameter of the trim ring forming the pick-up tube hole was too small. The tube pushed down on the gauze, working for the most part, but also separating the gauze from the square frame. Drop SRM an email and they will give a price. sales@srm-engineering.com

The screen is not available as a seperate part.
If yours is missing then get some bronze , steel or stainless mesh, cut it to the size of the sump plate.
Clamp it tightly between a couple of pieces of wood ( old ply or chip board will do fine ) and drill the 4 holes for the studs and another for the scavenge tube.
If you are real handy you can solder or weld a washer to reinforce the scavenge hole.
mount it between two gaskets ( cases-gasket-filter- gasket-sump ).
It's only job is to protect the scavenge side of the oil pump from being damaged by shards of metal.
Screen sizes always are a problem for me but you need some with a hole size around 1/8" to 1/16"

Trevor, I don't think I would use gauze with holes that large.

Agreed with Rocketman... The SRM plate is a nice bit of kit, easy to get to the sump plug if a wet sump occurs

Agree with Rocketman and LJ.
It is a nice bit of kit.
I'd have preferred it with longer versions of the original studs rather than shiny allen-head screws to attach the thing, as I've said before, because those threads are the last ones you want to be doing and undoing too much. But with the plug, it doesn't have to be taken completely off that often.

  Trev.

I should do some tests to see what will actually pass through the scavenge pump.
However I did have a few aftermarket sumps on hand and measured the mesh size.
The originals are up in the yard in the top paddock and that is 1/2 mile away but the next time I go there I suppose I should drag out a couple to measure them if for no other reason that to have the size on hand.

Now if you are going to fit an alloy sump then do by all means fit longer studs, much better than allen screws.
Torque should be in the order of 10'/lbs.
Also , very important, fit it with the drain plug to either side, not the front or back.
The reason for this is that should the plug drop out ( usually because you forgot to tighten it fully) then the contents of the oil tank will be blown directly onto the ground immediatly in front of the contact patch of the rear tyre ( not good )
