Sealey TC962 - Manual (Page 2)

4. OPERATION - TC961
the TC961 tyre changer is manually operated - no air supply is
required. It is designed for removing/fitting tyres from/to most sizes of
open-centre wheels (see section 3 specifications). Do not use the tyre
changer for any other purpose.
If tyres are to be changed on aluminium wheels the optional tyre bar,
sealey model no. TC963, must be used to prevent damage to the wheel
rims.
IMPORTANT! Never attempt to fit or remove a tyre without first
lubricating both beads.
4.1. Bead breaking
4.1.1. Deflate the tyre and remove all balance weights.
4.1.2. Lift the bead breaker clear of the tyre changer foot.
4.1.3. Place the wheel on the foot of the tyre changer, locating the rim
as indicated. Position the bead breaker spade under the rim
flange (fig. 1).
4.1.4. Put the tyre bar into the bead breaker socket.
4.1.5. Pull down firmly on the bar and repeat around the rim until the
bead is free.
4.1.6. turn wheel over and repeat to free the other bead.
Note: When bead breaking on tD or tDX wheels the wheel must be
horizontal. Locate the rim on the foot of the tyre changer and
support the opposite side of the wheel with a suitable piece of
timber.
4.2. Tyre removal
4.2.1. Lubricate both tyre beads with an approved rubber lubricant.
4.2.2. remove the wheel retaining sleeve from the centre post.
4.2.3. Place the wheel onto the stand with the narrow bead seat
uppermost.
4.2.4. replace the wheel locating clamp onto the centre post (fig. 2),
inserting the wheel peg into one of the wheel mounting holes.
4.2.5. turn the wheel clockwise on the stand until it locks.
4.2.6. Insert the ball end of the tyre bar beneath the top bead and press the opposite side of the bead down into the wheel well.
4.2.7. Lever the bar against the wheel location clamp and rotate the bead over the rim (fig. 3).
4.2.8. If a tube is fitted, tighten the locating clamp thumb screw to prevent wheel lifting and then pull out the tube.
4.2.9. Lift the tyre up and repeat the procedure for the lower bead.
4.3. Tyre fitting
4.3.1. Lubricate both tyre beads with an approved rubber lubricant.
4.3.2. Mount and lock the wheel to the stand as in 4.2.2. to 4.2.5.
4.3.3. Place the lower bead of the tyre over the wheel rim and insert the fitting head of the tyre bar
between the bead and the rim with the bead on the ledge of the fitting head.
4.3.4. Lever the bar against the wheel location clamp and rotate the bead over the rim (fig. 4).
4.3.5. fit a tube if appropriate and then seat the upper bead in the same manner.
5. OPERATION - TC962
the TC962 tyre changer is air assisted. It is designed for removing/fitting tyres from/to most sizes of
open-centre wheels (see section 3 specifications). Do not use the tyre changer for any other purpose.
Alloy Wheels. If tyres are to be changed on aluminium wheels the optional tyre bar, sealey model no.
TC963, must be used to prevent damage to the wheel rims (see fig.5b). use a rim sheild to protect the
wheel finish when levering a bead over the wheel rim.
IMPORTANT! Never attempt to fit or remove a tyre without first lubricating both beads.
5.1. Bead breaking (for 18” wheels refer to section 5.4)
5.1.1. Deflate the tyre and remove all balance weights.
5.1.2. Place the wheel under the bead breaker, locating the rim as indicated. Position the bead breaker
ram so that the spade is under the rim flange (fig. 5).
Note: Before operating breaker place one foot on the wheel, opposite the spade, to prevent wheel
‘kick-up’.
5.1.3. open the air valve slightly (see fig.5a) to lower the spade - do not use full pressure. check that
the spade is firmly set on the tyre bead, close to the rim and then increase the pressure
gradually until the bead breaks free.
5.1.4. rotate the wheel and repeat around the rim until the whole bead is free.
5.1.5. turn wheel over and repeat to free the other bead.
Note: When bead breaking on tD or tDX wheels the wheel must be horizontal. Locate the rim on
the foot of the tyre changer and support the opposite side of the wheel with a suitable piece of
timber.
5.2. Tyre removal
5.2.1. Lubricate both tyre beads with an approved rubber lubricant.
5.2.2. remove the wheel retaining cone from the centre post.
5.2.3. Place the wheel onto the rubber mat on the stand with the narrow bead seat uppermost.
5.2.4. replace cone over centre post and fit locating pin though post and both sides of cone tube.
(Precautions should be taken to protect the finish of an alloy wheel from the pressure exerted
by the cone)
5.2.5. Activate the bead breaker - this will pull down the centre post and so clamp the wheel.
WARNING! Make sure that feet and legs are clear of the spade when carrying out this operation.
5.2.6. Insert the ball end of the tyre bar beneath the top bead and press the opposite side of the bead
down into the wheel well.
