There will be a torque setting but Brians technique is fine.Half inch drive breaker bar, tighten till you fart.If you are 20 stone, 6’6’’ and built like Garth then amend to suit.Grease them well first and then leave alone till they need to come out.If greased properly then the 6 monthly turn em a bit is a waste of time and could lead to scraping the grease off.I use bog standard grease and copperslip on the threads.

Yeah think ill get the torque wench out
The thought of damaging the front cover or narrowing the gearbox casing and following through on the same night does not appeal!
And riding a t5 gets you close to one if the outcomes on a regular basis!!

Yeah it is the 4th down from the highlighted one in the list above dear Mike
To be honest I have 2 tourque wrenches
One is from Halfords and the dial type
the other is the one with the protractor type thing and is I find easier and as accurate to use and cheaper to buy

Worth looking at this test , Halfords came up best buy !!
worth looking an e-bay and Amazon
I was chuckling at the thought of someone tightening the bolt till they Farted , Annie asked what was so funny so I told her, she is still chuckling at the thought…
