Optional Equipment

Install Tandem Wheel Assembly (Center)

1.Slide spring wheel arm assembly (1) over right side of center wheel yoke tube and secure into position using four cap screw (22) and flanged lock nut (23). Repeat step to install spring wheel arm assembly on left side of center wheel yoke tube.

2.Place tandem wheel bracket (16) around lower lower spring arm (13) and insert flange pin (17). Secure flange pin to tandem wheel bracket using cap screw (18) and flat washer (19).

3.Insert wheel hubs (15) into both sides of tandem wheel bracket (16) and align holes.

4.Secure into position using cap screws (20) and flanged lock nuts (21).

5.Attach wheel to hub using five lug nuts. Install the chamfered side of the lug nut toward the inside for steel rim for pneumatic tires and rims. Tighten to 75 lbs-ft. Check that tire air pressure is a maximum of 40 psi.

NOTE: Install the flat side of the nut toward the inside for solid tires and aircraft tires (shown).

Install Tandem Wheel Assembly (Wing)

1.Attach wing wheel yoke (2) to the wing using pivot pins (31). See Figure 30 for pin and hardware installation. Make sure pin flange is on the underside of the deck.

2.Secure pivot pins to deck using carriage bolts (67) and flange lock nuts (53). See Figure 30 for pin and hardware installation. Carriage bolts are on the outside, lock nuts on the underside.

3.Place tandem wheel bracket (16) around lower lower spring arm (3) and insert flange pin (17). Secure flange pin to tandem wheel bracket using cap screw (18) and flat washer (19).

4.Insert wheel hubs (15) into both sides of tandem wheel bracket (16) and align holes. Secure using cap screws (20) and flanged lock nuts (21).

5.Attach wheel to hub using five lug nuts. Install the chamfered side of the lug nut toward the inside for steel rim for pneumatic tires and rims. Tighten to 75 lbs-ft. Set tire pressure to a maximum of 40 psi.

6.Install the flat side of the nut toward the inside for solid tires and aircraft tires (shown).
