#FAIRFIELD TORQUE HUB SERVICE MANUAL FULL#
In most instances we are able to repair the gearboxes to full working order, cost effectively.Īll parts used in our work are genuine Torque Hub parts. We provide guidance as to whether it is economically viable to repair a gearbox that has extensive damage. Until a full report is submitted and has been reviewed, there is no commitment required from the customer to proceed with the refurbishment. At this stage photographs are taken of the key components contributing to the failure and costings for parts and labour are calculated. After years of technical experience working with the complete Fairfield Torque Hub range, we are able to advise how this damage may have occurred e.g. This causes seizing of the gears and in some instances can lead to catastrophic failures resulting in irreparable damage to the gearbox.įollowing inspection of any gearboxes that we have returned to us, a written report is submitted to our customers detailing the identified root cause of the failure. This is typical for a gearbox that has been dismantled and then reassembled without appropriate timing of the gears. Further investigation revealed that the cluster gears contained within the carrier assembly were in very tight mesh with the ring gear. Upon removal of the piston the brake pack was revealed where evidence of wear to the steel and friction rotors was identified. The motor was removed and there were signs of perishing and deformation to the mating o-ring. The next stage was to dismantle the planetary drive to investigate further. Internal inspection and identification of root cause A roll test is performed on a test rig to identify any suspected damage to the gears or bearings. The pressure test identifies any potential oil leaks with the unit due to degraded or damaged seals. Typically, before dismantling the gearboxes a pressure test and roll test would always be performed. Externally, the 10 year old gearbox and motor looked in good condition with no signs of damage to the housing or spindle. Upon arrival, the Fairfield Torque Hub gearbox and hydraulic motor assembly was inspected for any signs of external wear or damage. The customer had already dismantled the gearbox and motor from the machine and were therefore able to organise the shipment of the part to our facility immediately in order to avoid further down time of the vehicle. The platform was completely out of use as the swing drive was no longer functional. This particular access platform rental company contacted us to ask whether we can provide support in getting this articulated boom lift back up and running. As the certified distributor and repair centre for Fairfield Torque Hub we often receive requests from end users to inspect, service and repair drives from this type of equipment.Ī recent project undertaken was for a swing drive assembly (Genie ref:88921) from an old Genie Z-80/60 Diesel driven, articulated boom lift. The Torque hub can be found on both the swing and wheel drives of both engine and electric driven machines. These leading manufacturers of lifting equipment have machines in operation all over the world. These gearboxes have been used by original machine manufacturers such as JLG, Genie and Haulotte for numerous years on a wide range of models of aerial lifts, scissor lifts and telehandlers. The Fairfield Torque Hub is a well-known brand of planetary drive in the aerial work platform market. Lancereal support the aerial work platform aftermarket as the certified distributor and repair centre for Fairfield Torque Hub.
