I finally got tired of unscrewing the cap nut to add lube to the reservoir. Went to a couple of pawn shops but couldn't find an 1 3/8 open end wrench. Apparently the big farmers in this area periodically go in an buy every wrench/socket in the store.
I got on Ebay and found what I hope will solve my problem. A 1-3/8" Thin Pump Open End Wrench Waterpump Wrench. It is used and looks it but should do what I want.
I'm sure I could get the cap off and back on if I heated it but I didn't want to do that. Bullet lube is thick and sticky and gets into everything.
