Every now and again it is worth just doing a quick visual check to make sure your rollers/slide on your trailer have not moved out of alignment.

Aligning the Trailer Rollers/SlidesAn important issue even for those without an L & RTM unit. The boat moves more easily on the trailer when it is properly aligned.The concept is..... align rollers/slides so that the centreline of the boat and trailer are the same - the boat should head for the centre of the Winch reel.The end result also will be that the boat will require less force to move it on or off the trailer.
Release the winch. The bow of the boat then should be lined up with ......- tow point - middle of winch post- middle of the winch drum - middle of the roller/v-block- middle of bow of the boat If not check with the tape measure and follow the procedure shown on the next page.

Make sure the trailer is on level ground. The tires should be equally inflated. The Boat must be ‘aimed’ down the Centre line of Trailer. Measure in from the trailer frame to the Pivot point on each side (L & R), and the distance from the ground up to the Pivot points (H) of the rollers/slides.Adjust so that L=R and H1 = H2 if needed. As the boat moves up the trailer’s centreline it should be equally supported on each side.

Essentially the boat needs to travel down the centreline of the trailer, with proper support from each side.When this is right it will also glide far more easily on & off.

You must grease all contacting parts on assembly. Stainless steel will ‘bind’ badly if you do not lubricate.Need to use high quality grease (yes that awful black stuff). The arm must be totally free to move with resistance otherwise it will not work properly.
Note : Seizing Thread Stainless has a bad habit of galling - it can lock up - seize! To avoid this use a lubricant.Loctite or Rocol Anti-seize, or moly grease even thin Teflon tape.
1 - No gap between roller & bow. 2 - Adjust [a], [b] & [c] so that the gap [f] between the Snare and the bar on the Latch = 1 thumb width (25 mm or 1”) [f] [a] [b]

Latch should hit Snare about here
Use a G-clamp to hold the Latch, under the winch plate to find the best location.

Adjusting the Latch relative to the Snare - this should be OK if it was installed properly but may have been moved out of alignment if trailer alignment adjustments have altered.

Note the relative positions of the rubber roller/bumper, the point that the snare hits the latch, and the gap between the boat and the rubber roller/bumper. Adjust the relative positions if required. See more info. under “Detail Install” on web site.

The Latch should move aside to give a finger spacing as shown in the photo (right). Note: the Snare, on the boat should be central. If it is not the boat may not be centrally aligned on the trailer.See Step (1).
One finger width max..
See Rubber bumper above. The Boat is at this point.
