2 Preassembly 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 2.7:1 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 9.7:1 to 17.4:1. Pro-Trim systems are custom designed to fit specific applications. For questions, or to place an order, please contact Harken.

4 Preassembly Planning installation Fasteners required - Drive sheave mounting Four 6 mm (1/4") round head or truss head machine screws Four 6 mm (1/4") nuts and washers Dual spool assembly Eight 6 mm (1/4") round head or truss head machine screws Eight 6 mm (1/4") nuts and washers Drive sheave line and cleat location Line diameter - 10 mm (3/8") Line spliced to form loop. Splice line after loading it onto drive sheave and through deck blocks. Use softer line with core so you can do a good butt splice. Line does not have to be strong as the only load it sees is what someone can pull. Splice must be perfect with a smooth, constant diameter and no hard spots. Make sure the splice is done by experienced rigger. Length - Mount 57 mm Carbo T2 blocks to footrests. Do not have sheave drive control line tight between blocks. Line should be just long enough so trimmer can sit out as far as possible and still operate control line. Do not make line excessively long either. Control line should have enough slack so that when you ease the traveler all the way the line runs out other side and stays inside boat. Deck Cleat Positioning - Make sure that when you pull weather control line sheave, drive does not pull leeward line into cleat. If it does, mount block higher so when you pull from other side it will automatically uncleat. Dual Spool Line (Aft Line that runs to car) Line Size and Type 3/16 or 1 /4" (5 mm or 6 mm) high-strength Spectra /Dyneema or similar. Length Two lengths of line are used. To estimate line length, consider that line will wrap around dual spool assembly 2 to 3 times, run through guide blocks, and through-deck sheaves located at end of traveler. The line continues to car located opposite the through-deck sheave. See line diagrams on page 6. Lines will be quite tight when car is at end of track. When car is at center, one side will be slack and will be taken up by shock cord tension system. Shock Cord Tension System Because line tension varies, due to line spooling on top of itself, a shock chord tension system must be used so line runs off dual spool assembly when traveler is eased to leeward. See diagrams to follow. Coupling Drive Sheave to Dual Spool Assembly Direct Coupling Mount dual spool assembly and drive sheave together with connecting shaft. Check to make sure that mounting and exits for lines can come up through deck at suitable locations. Couple using M6x1x55 socket head cap screw provided. Coupling using drive shaft If a shaft is used between assemblies, use universal joint to couple shaft to output and input shafts at units. Universal joint will compensate for misalignments between Sheave Drive Assembly and Dual Spool Assembly. Spectra is a registered trademark of Honeywell International, Inc.

5 Installation Mounting Dual Spool Assembly Mounting dual spool assembly Use mounting plate so that mounting brackets are aligned for smooth operation. With mounting plate in place, use supports as templates to mark holes. Drill holes and remove template by lifting up on plate and maneuvering to clear. Support Support Remove mounting plate once holes are marked. 07/2018 Pro-Trim Traveler 5

6 Installation Line must go to top of spool 57 mm Carbo Blocks Mounting Dual Spool Assembly and Drive Sheave Control Line Alignment Make sure there are direct leads to dual spool and drive sheave assemblies (see diagram). Line loop at drive sheave must enter so it is in line with thru-deck sheaves. Line running to each spool must be perpendicular to spool axle so it does not pile up on one end of spool. Make sure first lead block is 3' (1 m) or more from dual spool assembly. Deck Blocks Mount 57 mm Carbo blocks higher than cleat so that when you pull line from other side it will automatically uncleat. On some boats, the mm T2 loop block can be lashed to footrests. Control at Traveler 1st lead block must be 3' (1 m) or more Shock Cord Line perpendicular to spools Remote Control Block must articulate 6 Pro-Trim Traveler 07/2018

7 Installation Mounting Dual Spool Assembly and Drive Sheave Loading Traveler Control Line to Dual Spool Assembly 1. Start with line on roll, do not cut to length at this point. 2. Run line from one end of track along length to other end and into thru-deck sheave. 3. Run line through lead and tensioning blocks mounted to shock cord. 4. Once inside, run line to one side of take-up spool. Dual Spool Assembly (C13519, C13525, C12328) The dual spool assembly rotates in same direction as connecting shaft. Keep this in mind when winding line onto spools so car moves in desired direction when pulling sheave drive loop. Note that line comes off the top of spools see diagram. Line must come off top of spool. 07/2018 Pro-Trim Traveler 7

8 Installation Mounting Dual Spool Assembly and Drive Sheave Loading Traveler Control Line to Dual Spool Assembly (continued) 5. Deadend to center plate. Wind the spool so there are 2 to 3 wraps on the spool. This is important so deadend knot will not take shock load as car runs to end of track. Note direction of spool rotation. 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 new car location, along track length, into thru-deck sheave and down to open side of dual spool. 9. Wrap line 2-3 times around take-up spool in opposite direction as first line was wrapped. Deadend 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 between car and eyesplice. This allows adjustment later. 13. Tension system using lashing when car is at one end of track. Move car to middle of track. There will be slack in line. 14. Tension shock cord mounted below deck to take up slack. 8 Pro-Trim Traveler 07/2018

9 Installation Mounting Dual Spool Assembly and Drive Sheave Loading line to into drive sheave 1. Loosen pusher sheave bungee cord by compressing the cord lock mechanisms located in the supports. 2. Run 10 mm (3/8") drive line between the stripper and the guide sheave and around drive sheave. 3. Run line out through-deck block and through all turning blocks. Have a rigger do an end-for-end splice at a length where there is some slack as shown in the image below. Loosen pusher sheave bungee cord before loading drive line. After drive line is installed, tension pusher sheave bungee cord to where splice can pass. 07/2018 Pro-Trim Traveler 9

10 User Tips Using System Maintenance and Troubleshooting Using System Prevent car crashing from one side to other. Make sure car is cleated off at center for prestarts and downwind. Cleat lines when moored or docked. There will always be some movement when your car is pinned in middle for prestart or on downwind legs. This is not a big issue. At start always bias it so car stays just above middle on starboard side. When you go into a tack, have control line in your hand. Once you feel line unload on current tack, you already have new side in your hand because you are pulling it though block on other side. Pull fast if you want traveler to windward. In light air, pull car up to new windward side but keep your weight to leeward. If you want traveler to leeward, start letting control out and car will go to leeward but always load it so sheave drive doesn't free-wheel. If free-wheeling is a problem, tighten pusher sheave bungee adjuster. Adjust bungee tension so pusher sheaves pass splice yet drive sheave does not free-wheel. Maintenance Decouple drive shaft. Remove gear cover, clean and regrease. Inspect and replace all worn or damaged line or shock cord. Troubleshooting Problem Can t pull traveler up or there is to much force. Solution Make sure line is centered on dual spools and at right angle to the spool. Problem Line piles up on leeward side of Dual Spool Assembly Solution Use shock cord tensioning system. 10 Pro-Trim Traveler 07/2018
