1. PRO TRIM Installation Manual Pro Trim is a line driven power increasing system It consists of a drive sheave with a shaft connected to take up spools via a gear set The Drive Sheave box has a 4 1 mechanical advantage because of the larger sheave diameter compared to the axle Three gear ratios are available in the dual spool assembly providing an overall mechanical advantage from 9 1 to 17 1 Pro Trim systems are custom designed to fit specific applications For questions or to place an order please contact Harkene Sheave spool Dimensions Maximum Breaking Part Overall Mechanical Lx Wx Weight working load load No Description Advantage in mm in mm OZ g Ib kg Ib kg C8986 Drive sheave 5 906 150 3 232x6 84x8 559 87x175x218 42 1191 500 227 1500 680 C9656 Dual spool assembly 9 1 1500 680 3000 1361 C9657 Dual spool assembly 14 1 1500 680 3000 1361 C9658 Dual spool assembly 17 1 1500 680 3000 1361 H 50575 Coupler shaft 7 x 625 177 x 17 875 H 44836 Universal coupler kit Suggested Hardware See Diagrams Long Drive Shaft use if Drive Sheave and Dual Spool Assembly will be separated Drive Shaft Universal Joint angled shaft application Thru Deck Sheaves for Traveler Ends high load Thru Deck Sheaves for Drive Sheave low load Carbo Ti Lite Blocks allow fairlead with shock cord tension system 57 mm Carbo Blocks turn drive sheave line on deck on either side of2. of spools see diagram gt Line must come off top of spool 2 Pro Trim Traveler 8 20 09 Units built in 2008 C8440 Dual Spool rotates opposite direction as shaft Keep this in mind when winding line onto spools so car moves in desired direction when pulling sheave drive loop Note that the line comes off the bottom of the spools with the C8440 in the diagram N Line must come off bottom of spool Pro Trim 8 20 09 Loading Traveler Control Line to Dual Spool Assembly continued 5 Dead end to center plate Make sure there are 2 or 3 wraps on take up spool 6 Position car at end so it is opposite where line runs through deck Cut line off roll Temporarily knot line to car 7 While keeping tension on line turn Dual Spool so line winds up and car is at end where line runs through deck 8 To lead other side run line from spool located at car along track length into thru deck sheave and down to open side of Dual Spool 9 Wrap line 2 or 3 times around take up spool in opposite direction as first line was wrapped Dead end line to center plate of take up spool Make sure there are 2 or 3 wraps on take up spool 10 Cut line off roll and temporarily knot line to car 11 Check spooling so that when you pull one end of line off take up spool line winds onto other side of take up spool 12 Do not splice line directly to car Have an eyesplice about 6 152 mm from car Do a lashing b
