5. OPERATION
The TC962 Tyre Changer is air operated. 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 (fig.4), must be used to prevent damage to the wheel rims (See fig.4). Use a rim
shield 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 406mm wheels refer to section 5.4)
5.1.1.
Deflate the tyre fully 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.6).
NOTE: Before operating breaker place one foot on the wheel, opposite the spade, to prevent
wheel 'KICK-UP'.
Open the air valve (fig.5) slightly to lower the spade - DO NOT use full pressure. Check that the
5.1.3.
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.
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 slowly - 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
