Spline grease

[shadowrider]

I think I forgot to grease the splines on my gen2 LU. What is the main purpose of spline grease, To keep water out for future disassembly and friction/wear reduction. Hoping it will b ok for a season.

You mean the propeller shaft splines? . . . Makes it easier for the prop to come off when you want it to.

On the engine coupler you should have at least 1 zerk fitting you can shoot some grease in, rotate the shaft, shoot some more.
That should help some.

Re: Spline grease

I was working off you using the term "spline grease" which is in the name of the grease used for A, not B/C.

Re: Spline grease

The grease keeps the splines from wearing out, plus it keeps them from rusting.

On a gen II spline B in bathed in oil and needs no grease.

Re: Spline grease

The manual does show coating the B splines in 24c before assembly.
Maybe that's what he was asking about.
Sorry the picture is a little small but you can see the reference to using 24c.
