Alloy Sump plate and gauze filter?

[Joolstacho]

I just treated my SR to a very nice finned sump plate with removable magnetic drain plug.
The old sump plate has the brass filter gauze soldered into it's recess as standard. Should I make a new flat gauze and fit it between gaskets?
I could make a new 'dished' one but obviously ally and solder won't work. Set it in with Epoxy? Or... what do the gurus do?
Or maybe the magnetic plug is enough that the gauze isn't necessary.

When I bought my finned style sum plate it came with a gauze mounted in a frame that gets clamped between gaskets. They must be available somewhere.

Hmm I've had a nice sheet of fine brass gauze hanging around for years just waiting for this project!

the billet ones with the centre bolt dont come with the gauze or gaskets but gauzes are available. more annoying for me was the billet type dont have space to run with studs and nuts without machining around the holes…discovered after i fitted longer studs

The gauze plate is p/n 71-1126.
Here is an example supplier:

I just checked on eBay and found none cheaper than the fecked one

For your sump gauze, I would run not without it if your return pipe gets blocked no oil to rockers and your breather will blow out oil all over the place, very messy.
Part number 71-1126
£17.39

Good luck

I didn't check shipping, but SRM is 15p cheaper for the part, so, you can take yourself out for a steak dinner.

Anyone have any comment about the possible 'influence' of a magnetic drain plug on the ball in the scavenge tube?

Also... (and I'm sure I'm overthinking this). The original sump plate includes the gauze which rises approx 13mm (Arfaninch) above the level of the crankcase/plate surface.
If I fit/make a flat gauze plate like the Fecked one, the gauze ends up lower by about 13mm instead of 13 mm above it. So it's about 13mm lower than original setup.

Does anyone care? :-0

FYI, I stock both types of sump plates, cast and billet, and I stock the gauze filters. I'd recommend drilling out the holes in the sump plates to take the nuts which normally hold tappet covers on so that you don't have to disturb the studs.

[Joolstacho]

Cheers mate, I will use my existing studs I think. but it would need refacing the washer/nut lands, can do.
Trouble is with small parts from UK or US, postage to Oz can kill the value!
OTOH I need to order other parts (Auto advance bits) from you, so maybe we could sneak a gauze plate in the package!

G'day Jools.
Use tappet cover studs and nuts. No meddling with the plate needed. Both mine use them.
