Engine mount to front crankcase screws
Engine mount to front crankcase screws
I'm having some confusion about the way to check and tighten these screws. As I understand it, the test is to put a torque wrench on them and see if they turn at 36 ft/lbs. Well mine do, but how do you tighten them to spec. The manual is pretty vague even calling them different things in several different places. I tried putting a wrench on the top nut and tightening from the bottom which didn't seem to do anything. And if you do get them to tighten how do you know if you've over tightened them? My indy tried the same thing. The dealer was no help, of course. The service writer swore up and down that they didn't exist so I took him over to a bike and showed him...LOL. Any thoughts?

Here is what it says. It does not say torque the nut. You might be right but they used a lot if extra words if that's what they meant.
Number 8 in the notes is applicable.

The wording is common to mechanics. because there is a nut and a bolt, you have to hold one end or the other with a wrench while you tighten the other end. In this case its too difficult to put a torque wrench on the nut,so put your wrench there and torque from the bottom,[ on the bolt] while holding the nut still..... you may find that even after torqued you can still rotate the bolt if your not holding the nut. hope this helps.

I than placed an open-end wrench on the nut and applied force on the torque wrench. Bolt was now registering proper torque.

Ok I admit I thought as the OP. when I did my 1st service as per book.
But quickly realized you must hold nut.
I thought to myself why did they word it the way they did. Going fwd. Will not have trouble with that wording again.
I gotta hand it to the man at least he asked the question.

Thanks! I had the same problem and it didn't dawn on me that they would use a nut on the top. I feel stupid but relieved. That feeling when you pull the torque wrench and it keeps on pulling is like seeing cop lights in your rear view. I was thinking oh jeeze what did I just screw up now?
Exactly! I just happen to check these bolts last week. I first set my torque wrench to the lower setting (36 ft-lbs) and placed it on the bolt. I noticed that when I turned my torque wrench, the bolt turned and I first thought, "hey, this bolt is loose". I than looked closer and noticed that the bolt was threaded into a nut and not into some sort of threaded insert in a case.
I than placed an open-end wrench on the nut and applied force on the torque wrench. Bolt was now registering proper torque.
