Cast Oil Filter Mount

I have noticed a couple of Nortons where a oil filter was mounted onto a nice triangular shaped casting that bolts to the inside of the timing cover, where the points housing would have been on the early (1968) Commandos. The filter mount uses the original bolt holes for the blanking plate. It sits nicely in the space behind the barrels, and looks right.

Does anybody know if this triangular shaped filter body is still available?

Thanks,

This?

I would be interested in one also.

Thanks Traveljerry, exactly the oil filter mount I was thinking of.
Anybody have any idea who makes these? And any ideas on to get them?
I think the number stamped on the casting is actually a Fram number for the oil filter that it takes, rather than a Fram part number for the filter mount.

I've got one too but it's definitely an aftermarket period piece. Aged with no #s or brand names. Maybe a machinist here would be willing to make a batch.....

The oil filter was installed when I bought the bike 8 years ago. I searched the Fram website to find another but could not locate one. One drawback on it's location is when unscrewing it, some oil seeps on the side of the motor. I just stuff some paper towels beneath the filter to absorb the excess oil until unscrewed and pulled away.

I also now trying out a oil filter magnet placed on the end of the filter to trap any metallic material to the inside of filter. This I will check when I next changed the filter and cut the end off while the magnet is still on.

If you like your engine oil to get real hot this is definitely the way to go guys (oil cooler antipole) :!:

Yes guys, if you think the location is going to get the oil real hot. DON'T LOCATED IT THERE! Common sense would indicate the bulk of the excessive heat (combustion) is from the cylinder on up to cylinder head. Wasn't the electric starter motor located there on the 75's? (Funny that a gas tank is located just above the hottest area)

Again, it was there when I bought the bike at 17,323 miles. Looks odd for the location though. I've put on 15,000 miles without doing any major engine work. Change the oil/filter every 1,500 miles The 72 750 Combat just turned 33,000 miles the other day. Use Castrol 20-50W motorcycle oil. (I now add 2 ounces of ZDDP to every oil change) Going to run it until the bottom end fails. Have another Norton zipped up in a bag as a backup for immediate riding pleasure.

When the day comes to restore this bike, I would relocate an oil filter assembly underneath.

No offense Nortonspeed.
