17.6BRAKE PUCK REPLACEMENT

Tools Required: 5/32” Allen wrench; 3/8” wrench.

1.Remove the spark plug wire.

2.Remove the belt deck cover.

3.Remove the brake spring (A) and control cable spring (B) (see figure 17-10).

4.Remove the blade drive belt (C) from the drive pulley (D).

5.Using a 3/8” wrench and 5/32” allen wrench, remove the

nuts from the #10 puck retaining bolts (see figure17-11).

6.Remove the bolts from the puck.

7.Remove the brake puck.

Note: The puck ends are symmetrical and can be interchanged to use a new braking surface unless both ends are already worn (Figure 4). When both ends have been used replace the puck with a new one.

8.Inspect the nylon brake arm spacer (Item 44) by removing the belt finger (Item 91) and idler pulley (Item 50).

9.Replace the spacer if it shows signs of wear.

10.Reassemble all parts in the same orientation as when removed.

Note: Be sure that the brake puck is centered and contacts both sides of the pulley groove after tightening.

Note: Before installing fasteners, inspect them for wear and replace as necessary. Be sure that when reinstalling control cable spring (B), the open side of the spring hook faces up.

11.Check the operation of the clutch and brake mechanism. The drive belt should be slack and the brake engaged (center pulley will not turn easily by hand) when no pressure is exerted on blade drive lever.

Note: When the blade drive lever is depressed, the brake puck should not rub on the center pulley, the belt should be under tension, and not rub on the belt finger (see figure 17-10).

13.Replace the belt cover and connect the spark plug wire. Start the engine and check the clutch/brake operation under power.

Note: When the blade clutch control lever is pressed down, the blades should spin up to speed without belt slippage indicated by a pronounced belt squealing sound. When the clutch control lever is released, the blades should stop spinning in 5 seconds or less.
