Fairfield Torque Hubs

Fairfield™ Torque Hubs

W1A series Torque hub We stock a number of new, used and resealed torque hubs in the W1 series. These units are available in 30:1, 24:1, 35:1 or 18:1 ratios. The 30:1 units feature SAE A 2 bolt mounts and accept the 3/4" 24-tooth spline for either the Sundstrand 15 series motor or the Cessna 74118. The 18:1 units are SAE B 2 bolt mounts and accept the Sundstrand 18 series wheel motor with 7/8" 13-tooth spline. The 24:1 and 35:1 units will accept 4 bolt "B" motors with 13 tooth spline.

Our resealed units are thoroughly disassembled, cleaned, and inspected. Any units with severely worn internals are discarded. Rebuilding of gears and gear bearings is cost prohibitive so we do not salvage badly worn units. Sound units are then timed and reassembled using new spindle bearings, races, O-rings and main seal. Used hubs are $250 each. Resealed units $400 each and new units $750. Shipping weight is approximately 90 lbs. Shipping varies with zone but is generally between $60-$100. New hubs elsewhere often cost in excess of $1,100 with weeks of lead time unless a distributor has one in stock. Our stock of these units varies widely so check out our online inventory then give us a call or email. We do not normally have access to hubs outside of the W1 series.

We also have a selection of used and salvage parts. Click here for list.

typical nomenclature

Additional notes:

Hubs in the early W1 series are classed as either 'A' or 'B' drives, which refers to the internal arrangement of the planetary gears. Parts are not interchangeable between the two drive configurations. It should be noted that the drive class has nothing to do with the 'A' and 'B' of the SAE drive mounting shown above. In fact, all of our 30:1 'B' drive hubs have 'A' mounts.

Hub is an "A" Drive if last 2 digits= 18, 24, 40 or 60
Hub is a "B" Drive if last 2 digits= 30, 35, 49 or 68
