coupler question

(1/1)

cj92345:
just changed the gear ratio in my 8 3/4 olds and after getting it back together thought should I have greased the coupler? wasn't any in there when I took it apart, but should it have some?
thanks in advance

8 3/4 "OLDS"???    I always use a little anti-seeze before install but if its all together some spray graphite could be used but since there is no movement within the mesh its not nessasary to grease

dusterdave173:
All the top fuel teams used to and maybe still use Krytox grease--crazy expensive made for the space shuttle or some such--stupid expensive but...my top fuel crew pal said the stuff Really Works for no wear in coupler
again--when you look up the price you will shudder!
I used a tad of anti seize on mine --not too much or it will sling it all over everything

I lube mine about every other year.  No wear noticeable at all.

I use dry graphite.
