Greasing Pivot Points and Cam Bearings?
« on: June 18, 2018, 01:27:17 PM »
I have a horrible creaking noise at the pivot point on my Bowtech rpm 360.  I was told to grease the pivot point from a member at the local bow club.  Any recommendations on grease to use for both the pivot point as well as cam bearings? And to grease these parts will you need to put your bow in a bow press?

i am no expert:

but that sounds wrong.  i know one thing; grease attracts and holds grit/sand.  i bet it sounds great for a bit, and then sounds worse.

Agreed!. If the bearings are sealed, just lubricate contact areas on the outside. Any dry-on-contact teflon lube works well. Anything that is wet, (including grease) will attract grit and cause damage. I like to use graphite powder.

It's the rockers between the limbs and the riser. I have greased a few bows and the creaking will go away. Cam bearings are sealed. You basically need to take the limbs off the bow and grease the  entire plastic rockers and then rebuild the bow...big pain in the read end, but it does work. I use a heavy grease my buddy uses on motocross bike, but I'm sure a good lithium grease will work.
