Woods Equipment BW1620X Splitter Gearbox Assembly Figure, Splitter Gearbox Inspection, Side Shaft

Side Shaft

7.Remove seal (12, to be replaced) from the output shaft (13).

8.Remove 8 cap screws (3) and side shaft assembly.

9.Remove cotter pin (21), bearing adjustment nut (20), and gear (19).

10.Support side shaft assembly in hand press. Press shaft (13) through the cap (11) from the threaded end of the shaft.

11.Repeat steps 10 through 12 for opposite side shaft.

Inspect Components

12.Inspect gears for broken teeth and wear. Some wear is normal and will show on the loaded side of the teeth. Forged gear surfaces are rough when new. Check that wear pattern is smooth.

13.Inspect shafts for grooves, nicks, or bumps in the areas where seals seat. Resurface any damage with emery cloth or replace shaft.

14.Inspect housing and caps for cracks or other damage.

Splitter Gearbox Assembly (Figure 12)

1.Clean housing, pay specific attention to areas where gaskets are installed.

2.Wash housing and all components thoroughly.

3.Select a clean work area to assemble gearbox.

4.Replace all seals, bearings, and gaskets.

5.All parts must be clean and lightly oiled before assembly.

Side Shaft

6.Insert bearing cups (7) in hub cap (11) using a round tube of the same size diameter and a hand press.

7.Press bearing cone (7) on to output shaft (13), slide output shaft (13) through hub cap (11) and press bearing cone (7) on to output shaft (13).

8.Slide gear (19) over output shaft (13) and secure with nut (20) and cotter pin (21).

9.Check end play of shaft by moving it in and out. If end play is more than 0.012", tighten nut (20). Repeat process until end play is less than 0.012".

10.Check rotational torque. Torque should be less than 2.2 lbs-inch gear.

11.Place seal (12) over shaft and press into housing using a tube of the same diameter. Seal should be flush with housing when properly installed.

12.Repeat steps 6 through 11 for opposite side shaft.

Center Shaft

13.Insert bearing cups (7) in housing and front cap (4) using a round tube of the same size diameter and a hand press.

14.Press spacer (14), gear (18), shims (15, 16, 17) and bearing cones (7) on to input shaft (5).

15.Slide input shaft (5) through housing and install gaskets (8, 9, 10) and cap (4).

16.Check end play of shaft by moving it in and out. If end play is more than 0.012", remove a gasket (8, 9, or 10). Repeat process until end play is less than 0.012".

17.Check rotational torque. Torque should be less than 2.2 lbs-inch gear.

18.Check gear backlash, backlash should be between 0.006" and 0.016". Adjust the backlash by adding or removing shims (15, 16, 17) from the input shaft

(5).

19.Place seal (6) over shaft and press into housing using a tube of the same diameter. Seal should be flush with housing when properly installed. Repeat process for opposite end shaft.

Splitter Gearbox Inspection

1.Check gearbox for leaks by: plugging all holes except one, applying 4 psi of compressed air, and immersing gearbox in water. Verify gearbox does not leak.

NOTE: Excessive air pressure will damage seals.

2.Remove gearbox from water and dry off.

3.Remove upper plug on right side of housing. Add SAE 80W or 90W EP oil until it runs out side level hole. Replace plug.

4.Install breather (24) in top cover.

Splitter Gearbox Installation

NOTE: Gearbox is heavy: do not attempt to move with- out mechanical assistance.

1.Place gearbox on cutter and secure into position using four cap screws and lock washers.

2.Torque hardware to 300 lbs-ft.

3.Attach all drivelines to gearbox.

4.Install all shields.
