Upon studying the large workshop manual for an Electra X from our hosts, I note there appears to be a mistake.
The torque settings for the stud in the oil filter housing and the nut appear to have been transposed or wrong.
From the manual section 03-11:-
oil filter cover nut 17NM
oil filter stud 8NM

Can anyone clarify this please?

The cover is retained by a steel domed nut screwed onto a thread cut into a steel shaft. The shaft itself is screwed into an alloy thread in the oil filter housing and I guess can't be tightened as much without risking stripping the thread. I always tighten the cap nut to 17Nm without problem and I've yet to remove the shaft with the nut when undoing it.

Cheers for that. USUALLY a stud into aluminium has a coarse thread in the aluminium and a fine thread on the other end.
I am a tad wary of cranking up fine threads to high torques, especially 26tpi threads as even a mundane 35 ftlbs is exerting over a ton of pressure. That is why Locktite and Nyloc are my friends.

Frank, wait till you see the whole piece the stud screws into pulled out, I had to split the cases and drill in from where the barrel sleve is and counter sink a a 1/4 inch screw with a locknut on the other side. I think that motor has done over 30,000ks since and no problems

Hi, being new to "oily bits" just bought a torque wrench. Before I just tightened bits.

malc1091, I have two torque wrenches. One for brute strength and "Igrunts" for things like the bolts holding the rear wheel on our BMW K7SS and Squire ST1 sidecar outfit. (I fitted the sidecar, don't try it at home folks.)
The other one is 1/4" drive for low torque settings like exhaust pipe to cylinder head retaining nuts.
