In the unlikely event that the bearings do have to be replaced the procedure is as follows:
Bearings required: TA315: 2 x 6205 2RS C3 Metric Bearings.
1.
Isolate the machine.
2.
Remove the machine’s s
ide panel, gap plate, sawblade, and vee ropes,
3.
Remove the spindle pulley by unscrewing the 13mm bolt and washer located at the
end of the spindle, gently tap the spindle out of the opposite end using a soft hammer
and lift it up through the saw opening in the tabletop.
4.
If it is necessary to remove the riving knife bracket and bearing housing start by
removing the link from the riving knife bracket by unfastening the 13mm fixing screw
and nut (it will be important to re-assemble this part facing the correct way). Next
remove the bearing housing from the cradle plate by removing the four socket cap
screws located at the front of the plate. The bearing housing and riving knife arm can
then be removed as one.
5.
Tap each bearing out of its housing using a drift. Do not lose the spacer located
between the two bearings.
6.
Clean all parts thoroughly before fitting the replacement bearings and spacer on the
arbor.
7.
Refit the spindle and pulley and secure.
8.
Refit the vee ropes and tension them according to the instructions.
9.
Replace the machine side panel, sawblade, and gap plate.

9.6 Belt Tensioning
➢
The TA315 is driven via two SPZ487 vee belts.
IN ORDER TO ENSURE THE CORRECT SPINDLE STOPPING TIME (I.E., < 10 SECS) IT IS VITAL THAT
THESE ARE CORRECTLY TENSIONED AND REGULARLY CHECKED FOR WEAR.
Insufficient tension results in longer stopping times, belt slippage, loss of power (leading to
motor failure), vibration, whip, excessive noise, and accelerated wear of the belt and
pulley sheaves. Excessive tension stretches the belts, causes heat build up that
accelerates deterioration and places unnecessary strain on the bearings. A properly
tensioned belt will feel alive and vibrate when struck. If in doubt, the general rule is that
belts should flex about 1/32 inch for every inch of span between the centres of the pulley.
When the belts begin to show signs of wear replace them as a set, even if only one is
worn; otherwise, the newest belt will carry more of the load. Uneven loading results in
premature wear and vibration in the saw. Frayed belts will also cause vibration.
On the TA315 belt tensioning is performed as follows:
Lever between
the bolt head
and rib
