Surfacing 1
Surfacing should cover the base
of the seesaw with a 2"- 4"depth
and be level throughout the area.
(Please see Leg Attachment De-
tail) Warning: The seesaw de-
pends on correct surface height to
stop excessive movement. Ne-
glecting surfacing will lead to pre-
mature polyurethane rod failure.

Seesaw reassembly
Should the need arise to reassemble a seesaw please complete
the following steps:
1. It is easiest to tape the 4 polyurethane rods to the square bar in the base,
as shown in the diagram. A single strip of 1" masking tape (not pro-
vided) wrapped around the middle of the polyurethane rods should suf-
fice. Center the rods between the sides of the “U” shaped sheet metal
BaseAssembly and tape them so that the maximum distance (as seen in
the diagram) from outside to outside of both the top and bottom sets of
rods does not exceed 3". Install 2 bushings on the top base bearing face
with the thrust surface facing the side plates.
2. With assistance, place the seesaw weldment on the base/rubber/bushing
assembly.The halfclampon theseesaw will straddlethe top setof polyure-
thane rods and drop down on the bushings. Warning: Be careful not to
pinch your fingers in the assembly. The seesaw assembly will need to be
supported by a second person.
3. Install bushings in ends of lower half clamp. Lift the lower half clamp
into place so that it straddles the lower polyurethane rods. Have a sec-
ond person hold the lower clamp in place and balance the upper assem-
bly. Make sure both half clamps are centered between the sides of the
BaseAssembly.
4. Insert (4) 3/8" x 1 1/2" hex head fine thread bolts through the center holes
on the 4 corners of the half clamps. Use (8) 3/8" SAE flat washers on
both sides of the half clamp assembly, as shown in the diagram. It is
helpful to lightly lubricate the bolts with any available oil or grease (not
provided). Thread the 3/8" fine thread hex nuts onto the bolts and snug
each corner.
5. Evenly tighten the bolts in each corner until the half clamps are drawn
completely together. By tightening the bolts only a few turns each be-
fore going on to the next bolt, it is possible to keep the half clamp sur-
faces parallel to each other. Do not tighten a single bolt faster than the
others as the half clamps will skew at an angle and not mate together
correctly.
6. When the half clamps are just about to touch each other (1/32"-1/16" clear-
ance all around) place the (8) 3/8" tee nuts into the remaining holes of the
clamp assembly. Refer to the Base Assembly Detail on the next page.
The 3/8" tee nuts should drop all the way through the upper clamp holes
into the lower clamp holes. If the 3/8" tee nuts can not be pressed into
place, insert a punch or screwdriver through a clamp hole and pry on the
clamps until the holes of the upper and lower clamps are aligned.
7. With the first (8) 3/8" tee nuts in place and aligned correctly in the holes,
finish tightening the fine thread bolts. The half clamps should now be
touching. Install (through the bottom half clamp holes) (8) 3/8" x 7/8"
BHCS w/Pin and (8) D-Cut Flat washers. Tighten the bolts to 20 ft. lbs.
torque. Make sure the 3/8" tee nuts are seated against the half clamp.
There should be no space between the head of the 3/8" tee nuts and the
half clamp. If the 3/8" tee nut is not seated, loosen it and retighten in a
slightly different orientation until it seats.
8. Install (8) 3/8" jam nuts on the thread protruding out of the 3/8" tee nuts.
9. Remove and discard the fine thread hardware and washers.
10. Install the (4) Bolt Covers and 9/16" spacers with a 3/8" x 1 3/8" BHCS w/
Pin. Refer to the BaseAssembly Detail on the next page. In this case the
3/8" tee nuts come up through the bottom half clamp holes.
11. Install (4) 3/8" jam nuts on the thread protruding out of the lower half
clamp 3/8" tee nuts.
12. Re-Install the seesaw assembly per the seesaw installation instructions.
