Step 6: Drive Unit Installation
After the tracks and pulley’s have been installed, it is time to mount the drum drive unit.
The drum mounting brackets attach directly to the track, so the height and placement is predetermined.
This is why it was so important for proper track placement.
Grabbing the drum bracket that is missing the square delrin block, (this will be your drive side). Lift it up to
the track while pushing against the water side wall. Make a mark on the track where the main body of the
guide (not the tongue) meets the track. This is where you will cut the track so that you can attach unit.
After squarely cutting your track, be sure to file and de-bur to prevent rope fray. The tongue of the guide
will go inside the track after it is cut. Using a 3/8”in. wrench and flat tip screw driver, remove the guide
assembly from the bracket. Set the tongue of the guide on top of the track. You should be able to see the
center ridge line through the hole, mark through the hole using a pencil. Use a 11/64”in. metal drill bit and
drill the track. Slide the guide tongue into the track, the holes should match up. Lift drum bracket up to the
track and guide, the bracket guide screws should slide into the guide. Attach nylon lock nuts and screw. The
unit is now held in place for drilling. Use the small torpedo level to keep the bracket vertical, drill with ham-
mer drill and install screws and anchors. Repeat this procedure on the non-drive side.
Step 7: Installing the Cover Drum
Now that both drum mounting brackets have been secured, it is time to install the cover drum
The drum is held in place by two white delrin blocks. These blocks have two grooves on either side that allow
them to slide into the bracket . There is also a retaining plate that slides into a notch in the bracket and held
in place with a Philips screw. Remove the block from the non-drive side bracket and slide onto the drum
shaft. You may have to use a 7/16”in. wrench to loosen up the bolt on the block to allow it to slide onto the
shaft. The drive side block is already attached to the drum. Once you have the block on, you can now set the
drum in place by sliding the two blocks onto the bracket with the grooves, and then sliding the retaining
plate into the notch and tightening the screw to keep it securely in place.
Now you may have to center the drum evenly between the tracks. To do this, loosen up the two 7/16”in bolts
on the white delrin blocks and use an allen wrench to loosen the two piece lock collars that hold the pole
sockets into place. Shift the drum (left or right) until it is centered between the tracks. Use a tape measure to
find the center between the tracks and mark with a piece of chalk, align center of drum (as indicated by a
hole with a circle around it), to the chalk mark. Now slide lock collars and pole sockets over as well and
tighten up. Be sure to allow a little movement between pole sockets. Tighten the 7/16”in. bolts to the point
where you can rotate the drum with relative ease, but not to the point where it will continue to spin on its
own.
When all is repositioned, and tightened, place both poles into the sockets creating a “V” shape. There are
tabs on the sockets that should be at the top, not the bottom. If you place the poles into the sockets and they
create an “X” the sockets need to be spun around. With the sockets in properly simply alternate poles in a
back and forth motion. The drum should rotate away from the pool. If not, you have either placed the drum
in incorrectly or the wrong side unit was ordered.
