Trophy92 | Technical product information7.9 Service information transaxlesSummaryEnd of 2008 Handicare has published the product update "Trophy with S-Drive Controller". Among other things, this updatementioned the new sturdier transaxles for Trophy with Egis controller and for Trophy with S-Drive controller. Since the benefits ofthese new transaxles remained underexposed in the load of information in the news item, we will explain here the improvementsto the transaxle and summarise service instructions for these parts.The new transaxles (Egis or S/Drive configuration) offer improved bearing and bearing position. New, bigger motor brushesalso contribute to extend the life expectancy of the parts and reduces costs of ownership.Regular preventative service checks are important to verify the condition of the parts and enables to replace them at the righttime. See service instructions.DescriptionThe new transaxles (standard and heavy duty / Egis and S-Drive compatible) as presented in our Product News item "Trophywith S-Drive Controller" dated 10/09/2008 offer improved performance and life expectancy. This is due to the improved bearingand bearing position but also to some changes that were made to reduce wear of the commutator and brushes. This way servicecosts are reduced.The new transaxles are equipped with bigger motor brushes. As a consequence the current density (Amps/mm2) in thecommutator and brushes drops and this improves the life span of these parts. The effect is more pronounced in the Trophy Egisbecause this controller uses higher currents than the S-Drive controller.Regular preventative service checks are important to verify the condition of the parts and enables to replace them at the righttime. Therefore see the service check instructions.Service checks instructionsCheck if dimensions of commutator and motor brushes satisfy minimum dimensions as indicated in the illustrations, accordinglyto the table below.Part Trophy with Egis controller andSchmid transaxleTrophy with S-Drive controller andSchmid or CT transaxleCommutator Once every 3 years Once every 3 yearsMotor brush At least once a year or every 1000 km At least once a year or every 3000 kmClean the collector on the anchor of the motor with pressed air from dust.Commutator Schmid Egis controller and SchmidtransaxleS-Drive controller andSchmid or CT transaxleDimensions:• minimum 35,4mm.Dimensions:• maximum(17,5mm)• minimum(9mm)Dimensions Schmid:• maximum(16mm)• minimum(8mm)Dimensions CT:• maximum (18mm)• minimum (8mm)917,5816/18
