Torque spec question

[goosehntr]

I am putting the lower unit on my 92 40hp johnson back together tonight and have a question. I assume i should use some lock tight on the nut on the end of the drive shaft. I do not have the "special tool" for the drive shaft nut so i am just using a thin wall open end wrench. worked fine to remove it.. but my question is, is there a torque spec that i have to tighten this too or if i use locktite and get it good and tight will it be ok?<br /><br />chad

Re: Torque spec question

What wrench did you use to get the pinion nut off besides your thin wall wrench. The torgue is 65#, but I don't know how much that is with a pair of vice-grips.

I used a thin wall wrench on the nut and a small rubber padded pipe wrench on the center of the drive shaft..is is ok to use the locktite on it as well?<br /><br />Thanks<br />Chad

Re: Torque spec question

That nut should be replaced once removed. Certainly Loc-Tite would be good insurance. If that nut comes loose, you are looking at over $400.00 in gears alone. A pipe wrench has no place in the replacement of these kind of parts. Use the proper socket, and torque wrench.
