Removing Sidecar Wheel

Raise wheel by blocking up under sidecar chassis. Loosen nut that secures fender front bracket to sidecar step lug. Loosen the fender inner brace clip bracket nut. Remove outside axle nut, lock washer and outer brace. Hinge fender forward, taking care to provide slack for taillamp wiring. Remove extension nut, axle nut and washer. Pull wheel from axle with brake drum attached.

Detachment of wheel from brake drum is necessary only when wheel or brake drum is to be replaced or wheel interchanged. To detach wheel from brake drum, remove the five wheel mounting socket screws that secure wheel to brake drum.

To replace wheel, reverse removal procedure. Tighten wheel mounting socket screws securely to avoid possibility of wheel working loose and damaging hub flange.

SERVICING WHEEL HUBS (Fig. 2C-3)

All spoked wheel hubs are identical. However keep oarts for all wheels separated. Bearing assemblies (20 21 and 11, 12) and thrust bearing adjusting shims 7) have been fitted at the factory, and subsequent LI "repairs may have included instalUng over-e bearings. A transposition of parts will result in oversize or undersize fit.

DISASSEMBLING WHEEL HUB (Fig. 2C-3)

Remove five thrust bearing cover screws (1) and E washers (2). Lift off thrust bearing: ou er cover (3), cork grease retainer (4), thrust bearing housing (5), gasket (6), a number of ^usUng shjms (7) which varies with the hub, thrust washer (8), thrust bearing sleeve (9) and another thrust washer

Remove bearing rollers (11) and retainer (12), and roller retainer thrust washer (13).

Turn hub over and remove spring lock ring (14) retaining washer (15), hub inner sleeve (16), cork grease retainer (17), spring lock ring (18) and roller bearing washer (19).

Large diameter retainer (21) and bearing rollers (20) are then free to be removed from hub shell (¿¿).

INSPECTION AND REPAIR (Fig. 2C-3)

riean and dry all parts and inspect for wear, if excessive sfdeplay i's present one or = bearing adiusting shims (7) must be added. Thrust bearing sleeve (9) must be free with thrust bearing outer over (3 completely screwed down A prance nf 005 in to .007 in. is correct. Leave corK grease retainer (4) out of thrust assembly while determining correct adjustment of thrust sleeve, and reinstall it when adjustment is completed.

Excessive radial (up and down) play in wheel^ hub bearings can be taken up by fitting oversize ro lers (11 and 20). Bearing rollers are available from 001 in. undersize to .001 in. oversize in steps ot '.0002 in. Select roller size that will give .001 in. to .0015 in. clearance.

ASSEMBLING WHEEL HUB (Fig. 2C-3)

Assemble hub components in reverse order of disassembly. Closed sides of roller bearing retainers U2 and 21) go toward center of hub. Be »we to include a plain washer (25) under grease fitting (24 in thrust bearing housing (5). Failure to do so wi 1 cause end of fitting to crimp adjusting shims (7).

Apply a thin coating of ' Grease-All" grease to rollers, races and thrust washers. After final assembly, inject 1 ounce additional grease into hub. Carefully check hub to avoid a bearing fit too tight. Roller bearings must turn freely and have slight play. Do not over-lubricate hub. An over-lubricated hub uu , ________«■ K^dlio accpmb V.
