Locktite on Flywheel bolt?

[sxi steve]

I'm replacing stock with RAD lightweight..., Use blue Loctite on the Flywheel Bolt? Yes or no? Just leave dry?

I always use anti seize and tighten with a couple braps of the impact.

Don't use antisieze. Use blue loctite if any and TORQUE IT!

 

[sxi steve]

The reason I ask is cuz there was an orange looking substance on the bolt when I removed it. Also Loctite is used on mostly all bolts.

loctite that bitch! and tighten it with a breaker bar if you dont have a torque wrench. git 'er on good!

 

[Idok]

I do the same as mark 44 and have never had one come loose...........alum flywheels though can be tricky, I'd do exactly as RAD instructs

 

[yamasaki]

ive never had one come loose either.. that bolt always makes me nervous. seems so important. hahaha. i always get on it real good.

 

[sxi steve]

Yeah, blue loctite and torqued to 70 ft lbs makes sence to me. Any objections with the 70lbs?

Thx

Yep go by RAD instructions. On stock flywheel I also put anti seize on the crank end and key before installing the flywheel.

70 LBS is about right. Or two trusty braps from my impact.:bigok:

anti-seize and impact... I don't use locktite on anything that goes in saltwater...

I just clean the threads and put it in dry...torque to 75lbs.

 

[sxi steve]

Why the anti-seize? Can the two parts bond?

what all bolts does everyone use anti seize or locktite on????
I put anti seize on my girdle studs both ends for sure.

I may be wrong but that may be some sort of anti-galling(sp) compound from the factory.
I'm with Nick, no anti seize on anything that touches salt water (ie intake grate bolts, rideplate bolts etc)

Loctite should not be necessary for long or high tension bolts. There is no place on a watercraft that gets hot enough for antisieze. Every bolt should be sealed at the head and threads unless its stainless on stainless. Yamaha used a teflon pipe sealant and Kawasaki coats most of their bolts with a soft green sealant. I do use some marine grease on flywheel bolts with a little less torque than I would a dry bolt. This keeps water out and provides the same tension. As far as warercraft go, Loctite is just insurance for careless assymbly.

i thought the yamaha manual says marine grease????

we torque the kawi alum flwheels to 100 fts lbs. no loctie.

i heat cylce it, and re-torque it. i then re-torque after 5, and 10 hrs run time. you can fit a 3/8 drive deep well 9/16, or 14mm socket in the hole where the oil pump goes.

this has been fool proof for us, no problems.

happy new year!

The manual says to apply 2-stroke oil to the threads before torque it to 51 ft-lbs.

I use the high heat red Loctite and torque it to 75 ft-lbs. on modified engines with more compression.

I don't think that most people understand how antisieze affects the torque of a bolt.
