I don't believe a Loctited bolt is the same as a Dry bolt for the purposes of a torque check. Once the Locktite is broken it will impose a stiff running torque on the bolt but it may not be the same as a dry bolt.
I was a main player in the original loose bolt issue when the issue first arose. My original KAI drawings for the motor mount installation actually specified a torque value for the bolts - 26 ft-lb. Vans probably regrets ever having done that. Now they refer to the Rotax installation manual. As Scott points out, the torque value should have been 30 ft-lb. But, in addition, the later KAI drawings were revised to show that the powder coating is to be scrapped off of the engine mount at the mating surfaces to the engine. The original drawings did not so state. I believe that the low bolt torque of 26 ft-lb contributed to fretting wear of the powder coating on these original installations, like mine, and resulted in loosening of the bolts.
Back then, there was a lot of back and forth discussion of using Loctite. My thinking was that it would not be possible to check torque on the bolts if they were locked in with Loctite. The function is in the name!
Also, if there is fretting wear at the mating surfaces, then a Loctited bolt could be loose and torque seal and even a torque wrench may not reveal that.
Am I over thinking this!?
Anyway, I see the Rotax installation manual now states Loctite 243. Without doing a lot of fruitless research I don't know if the Rotax instructions included that requirement back 13 years ago, but I doubt it I also don't know how you check a Loctited bolt without breaking the seal, does Rotax speak to that somewhere?
