Rear Fork Pivot Shaft Lock Nut Torque

[JTJersey]

At 20,000 miles the manual says to check the Rear Fork Pivot Shaft Lock Nut Torque. The torque value says 50 ft-lbs first torque. It follows that with "Torque: (180 ° ) Rear fork pivot shaft locknut, final torque"

What are they talking about?

Torque to yield, mark the nut, turn 1/2 turn 180 degrees

or get this from Advanced Auto about 15.00

Ok, sorry for my ignorance, but what does "Torque to yield" mean?

Most often it is not a torque in ft lbs with a torque wrench, but a tightening in degrees after torquing with a torque wrench

This became popular by HD on Evo engine head gaskets

Thanks, but I still have no idea how to do that. Think I'll let the shop check it.

Think of it as adjusting a Trouble head clutch basket, after torquing the swing arm nut, back off the torque wrench and give the nut another 1/2 turn like you would a clutch hub adjuster( 180 degrees = 1/2 turn, 1/4 turn =90 degrees

Or think a clock face, starting from 12-6 =1/2 turn

Starting to make sense now, thanks. Don't you have to hold the nut on the opposite side to keep it from turning?

Good question, I dunno

I feel that would be your best bet if you’re not sure.

Being inquisitive, I put a torque wrench on the right side nut just to see if it was loose. If you try tightening the shaft nut the whole shaft turns, the nut on the other side with it. I guess this would make sense being as the shaft is simply a round rod with a nut on either end. I put a socket on both sides to check for movement and it was pretty damn tight so I put the cover plugs back on and decided it was fine.

Let sleeping dogs be!…..You have to avoid the temptation to want to put a tool and turn every visible nut thats why they put cover plugs on nuts;IE..To keep inquiring eyes and hands off of them…

How about inspecting the rear sprocket isolators? Another tidbit Harley recommends to be checked at 20,000 miles? Anybody ever do that?

Those recommendations are a bone that Harley trows out to their dealers so the dealer can make a extra buck…
