Final Installation
The HS17000 is a two-speed powershift transmission capable of shifting gear ranges while the vehicle is in motion. The speeds are obtained through the use of electrically controlled solenoids and hydraulically actuated multiple disc clutches.
The clutches in these units are hydraulically applied spring released or spring applied hydraulically released. There is automatic compensation for normal wear which eliminates the need for adjustment. Each clutch uses a composition friction plate and a polished steel reaction plate.
Like all mechanical equipment, the HS17000 will need attention and servicing. Routine checks will help prevent downtime. The operator can aid in preventive maintenance by reporting weak or borderline malfunctions.
Because the unit operates “in” oil and “by” oil, most of the maintenance is concerned with oil replenishment and oil cleanliness. The type of service and operating conditions shall determine the maintenance interval. However, it is especially important that the oil be kept clean.
