M41 3/16 shaft upgrade installation questions

[Nygaard]

I have a Traxxas DCB-M41 I bought the larger shaft upgrade, 3/16. The drive dog that came with the upgraded parts has 2 grub screws but the shaft it connects to has only one flat spot. Is there supposed to be another or just use one. Also should I use loctite on any of these locations?

Thanks I advance.

Use both set screws on the coupler and one on the drive dog.A little Loctite won't hurt. Mark is right, I thought it said coupler when I originaly answered this.

You only need 1 set screw on the flat and use blue loctite on both set screws.

2 holes 2 screws,,, use them both
Also blue lock tight
One should go on flat of shaft.
A lot of heavy equipment Hydrolic pups come with 2 = extra strength.
My opinion of corse
