WHX?? 48,801 #1 Posted April 16, 2022 (edited) Working on a 7-1311 sickle bar. Need to know the diameter of the engine pully as it never made it off the PO's tractor. Part #105 What lube do guys run in the wobble box? Manual calls for 30 wt. but was thinking trying 80/90 or maybe corn head grease? Edited April 16, 2022 by WHX??

Racinbob 11,045 #2 Posted April 17, 2022 (edited) Jim, I think your set up is a bit different than mine. My sickle is a bit older than yours and it didn't show a different pulley for the drive. I'm running mine off the standard 3 groove pulley which I believe is 2.5". I can verify that a bit later this morning. I certainly wouldn't want to go bigger because I'm barely above idle using it as is. As for the lube I'm using the 30w as called for but I don't see why a heavier lube would hurt. Verified that engine pulley is 2.5" Edited April 17, 2022 by Racinbob 1 Share this post Link to post Share on other sites
