The particulars of the powerflow is a single countershaft
design owing to the relaxed packaging restriction along the transmission axial length due to the longitudinal orientation.
In conventional variable stepped transmission with a countershaft
, there is a pair of gears for each step.
MMC said the casting on the front bearing mount supporting the countershaft
has an uneven finish and the front bearing lacks sufficient strength to support the countershaft
, which may allow the vehicle to operate only in fourth gear.
The L70D - L330D are equipped with efficient countershaft
transmissions which now feature four speeds in both the forward and reverse ranges for fast and efficient work cycles.
The full powershift, countershaft
transmission features three forward and three reverse speeds that increase productivity by reducing machine cycle-time through faster ground speeds.
Recently introduced is the T-2110B 11-speedvocational transmission, providing municipal customers with reliable triple countershaft
performance for on- and off-road applications.
John fabricated shackles and corner brackets for the rear axle and countershaft
. "We basically scavenged parts all over the Midwest," Tom says with a laugh.
Internally, bronze sleeve bearings are used for all moving components that are load bearing or perform load transmission (including countershaft
bushings, thrust bearings, head and eccentric bushings and socket liners).
The 950L and 962L also use a 5F/3R countershaft
power-shift transmission - a high-capacity torque converter that uses a lock-up clutch for efficient grade and high-speed performance, together with the Cat APEC control system, to maintain torque flow during range shifts for faster acceleration on ramps and smoother shifts in the transmission's direct- drive mode.
has introduced the Rangermatic two-speed bidirectional countershaft
drop powershift transmission, which is designed to be used in applications that require a quick and smooth transition when inverting direction and changing speeds.
This transmission is based on a countershaft
design that essentially comprises two inter-related manual transmissions with two input shafts, one for the odd numbered and one for even numbered gears which share a single output shaft.
