Pinion keeps coming loose

Post by millersavage » Thu Nov 14, 2013 12:10 am

Any tricks to keeping the pinion tight? It seems to come loose after a few packs. I am using red lock tight on it.

scuff the motor shaft with scotch brite or similar to give the loc tite something to bite to. ( i use blue loc tite  ) my pinions have never come loose.

make sure that you get rid of all fat or greese with a good cleaner that leaves no residue ( i prefer brake cleaner )

it is very important that the grub screw used has no damage inside the hex and your tool fits in there perfect so that you can get the desired tightness. best is to install new grub screw every time it has gotten loose instead of retightening an already ruined one. ( if the grub screw has rounded off on the end touching the motor shaft, then you need to replace it )

never buy cheap tools to tighten your hardened hex bolts. ( biggest reason for not being able to tighten hex bolts to the needed tighteness is crappy tools)

i should stop here but i could go on for pages for how to tighten and glue pinions.

I use Tekin pinions. They come with an oversized grub screw that you can really crank down tight.
