Troy-Bilt 42052, 42051 F. Attach Chute Control Rod, H. Attach Wheel Drive Control Rod, Assembly

Section 2: Assembly

6.Remove the washer and locknut from the screw (M, Figure 2-4) in the worm gear assembly (L). Position the worm gear assembly on the mounting bracket as follows:

a.Engage the worm gear threads 1/2- way with the teeth on the flange of the discharge chute base (rotate chute as needed).

b.The length of the worm gear should be centered with the teeth on the flange of the discharge chute base.

c.Reinstall the washer and locknut on the screw (M) and tighten securely.

7.Insert the flexible fins on the plastic snow deflector (N, Figure 2-4) inside the chute deflector cap (O). Close the deflector cap by pulling the lever (P) outward and moving the deflector cap down. Release the lever to secure the deflector cap in one of the discharge angle selector holes.

F. Attach Chute Control Rod

1.Remove the plastic tie that secures the auger drive control rod (AA, Figure 2- 5) to the right handlebar. Next, re- move the plastic tie that secures the chute crank rod (short rod with plastic swivel blocks) to the auger drive con- trol rod.

2.Pull the chute crank rod (Z, Figure 2-5) up through the top of the control panel.

3.Attach the chute control rod sections (S and U, Figure 2-5) as follows:

a. Insert the angled end of the chute control rod, (U, Figure 2-5 inset) into the hole in the swivel block (V) that is attached to the end of the chute crank rod (S).

b. Insert a cotter pin (W) through the hole in the chute control rod (U) and spread the ends of the cotter pin.

4.Position the chute control rod support bracket (Y, Figure 2-6) against the un- derside of the handlebar console as shown. Secure the bracket with the two #10–24 x 3/8" Phillips pan head screws and #10–24 locknuts supplied.

5.Rotate the chute control crank (Z, Figure 2-5). The discharge chute should turn freely, but with enough re- sistance to prevent free rotation of the discharge chute during snow removal operation. Adjust the worm gear as- sembly bracket (L, Figure 2-4) as nec- essary to prevent binding.

G. Attach Auger Drive Control Rod

1.Remove the plastic tie that secures the auger drive control arm (AD, Figure 2-7) to the transmission shift arm (AB).

2.The auger drive control rod (AA, Figure 2-7) has been pre-adjusted at the fac- tory. To avoid misadjustment, do not rotate the jam nut (AT, Figure 2-7) while completing the following steps.

3.Hold jam nut (AT) in place with a 7/16" wrench and use another 7/16" wrench to thread the adjusting thimble (AS) downward a total of 12 turns.

4.Raise Auger Drive Control Lever (X, Figure 2-5) all the way up. Then hook the spring (AC, Figure 2-7) at the lower end of the auger drive control rod (AA) into the hole in the auger drive control arm (AD).

5.Thread the adjusting thimble (AS, Figure 2-7) upward until it contacts the jam nut (AT). Using two wrenches, tighten the jam nut against the adjust- ing thimble.

6.Check that the spring (AC) is under the correct amount of tension by perform- ing Steps 2 through 5 of Auger Drive Belt(s) Adjustment in Section 5 of this manual.

H. Attach Wheel Drive Control Rod

1.Remove the plastic tie that secures the wheel drive control rod (AE, Figure 2- 7) and the gear shift control rod (AF) to the left handlebar.

2.Hook the spring (AG, Figure 2-7) at the lower end of the wheel drive control rod (AE) into the hole in the wheel drive control arm (AH). If necessary, raise the wheel drive control arm (AH) while attaching the spring.

3.Check that the spring (AG) is under the correct amount of tension by perform- ing Steps 1 through 4 of Wheel Drive Disc Adjustment in Section 5.

4.The wheel drive control rod has been pre-adjusted at the factory. When the engine is started, as described in the Operation section, you will be given a functional check to make sure the wheel drive control rod is properly adjusted.

I. Attach Gear Shift Control Rod

1.Place the Gear Shift Select Lever (T, Figure 2-5) in the No. 5 position.

2.Gently push the transmission shift arm (AB, Figure 2-8) fully downward.

3.Align the holes in the transmission shift arm (AB) and the lower end of the gear shift control rod (AF). If the holes do not align, follow the Gear Shift Rod Adjustment procedure in Section 5.

4.Use two 1/4-20 x 3/4 hex head screws and 1/4-20 locknuts (Figure 2-8) to attach gear shift control rod (AF) to transmission shift arm (AB).
