Cam Gears Install Question

[TopCatGr58]

The Loctite is simply added insurance that the bolts won't back out again.

+1 , the cam bolts are SPECIAL kind, and so as long as you've used the same bolts and properly torqued them, then you shouldn't need to worry about them....just remember to do them the next time you have the valve cover off for a clearance check. I didn't use locktite on mine over 10 years ago when I did my little big bore kit, no problems so far!

Question for you guys, red locktite or is blue good enough (that's what I used - thought I might have to heat them up to get them off again).

[crazy steve]

Blue is plenty good if they were torqued to the right value.

Yep, red is for Harley Davidsons.

Locktite

Question for you guys, red locktite or is blue good enough (that's what I used - thought I might have to heat them up to get them off again).

I have not had to use heat to remove a fastener with the red applied but once. That was many years ago on some 9/16" fine threaded bolts.

Blue Locktite takes longer to dry/cure than red. Therefore when used in areas where oil is present, you need to make sure that it has had time to do so. Red cures quickly.

Torqueing to specs is a definite must. Suggested torque specs for fasteners are given with the assumption that the parts to be fastened are extremely clean. Too many times this is not the case and the fasteners seemingly fail.

I do not trust the blue. I ALWAYS use red. I have critical applications that red is a must. Horror stories that you have heard in the past disappear when using this type of insurance. Bottom line is: Why take a chance?

LOL, I bought my first BIG bottle of blue locktite for my Harleys. You want to be very careful with the red, you can break off case bolts if you use that too liberally. DAMHIKIJK....

Steve, If blue passes the Harley paint shaker test, I'm sure it's just fine on a Yamaha.

I've never used any loktite on the cam gear bolts, it is cheap insurance I guess.

Speaking of locktite, it's actually used and instructed to be used by the FSM, or at least the Clymer's with regards to the bearing/oil countershaft holder that attaches to the side of the engine case with the 3 torx screws/bolts. That receives quite a bit of vibration and stress from the countershaft/tranny, and they are just countersink type screws, so that's why I guess they state they need locktiting!?

At least they used Torx and not Phillips. It's part of the oil distribution system to the transmission so they were taking no chances!

I'm actually kind of surprised the factory didn't use thread locker on the main oil gallery plugs too. I did.

+1 here on the thread locker. A lot has changed in fastener torque techniques since the late seventies and early eighties. We now insure that torque specs remain in tact with the likes of Locktite. Just when you thought you knew all there was to know, out comes torque angle? "Always Something"!

Thanks for that rabbit hole!

BIG +1 now everything I work on at my job is some stupid s**t like "torque to 75 ft lbs and then 1/4 turn".


Ahhhhhhhhhhhh!!!!!!!!!!

that be torque-to-yield, one time use.
