02 MT (R150)

The document discusses 4 manual transmissions - R150, R150F, R151, and R151F. It provides details on: 1) The application of each transmission based on engine and drive type. 2) The adoption of a lever-type synchromesh mechanism for 5th and reverse gears to enhance ease of operation. 3) Specifications for each transmission including gear ratios, oil capacity, weight, and synchromesh mechanism details. 4) The operation of the lever-type synchromesh mechanism, which uses two shifting keys to reduce shift effort for 5th gear and prevent gear noise when shifting to reverse.

 LEVER TYPE SYNCHROMECH MECHANISM

1. General

The lever type synchromech mechanism consists of 2 shifting keys, shifting key spring, and shifting key
return spring.

2. Operation

 While shifting into 5th, the 2 shifting keys move in unison with the hub sleeve (F1). With "A" acting as
the fulcrum, the 2 shifting keys move to push the synchronizer ring only for the amount of the lever ratio
(F2). The shift effort can be reduced only for this amount.

 While shifting into reverse, with "B" acting as the fulcrum, the 2 shifting keys move to push the
synchronizer ring (F2). As a result, a brake is applied to the rotation of the counter shaft and gear noise is
prevented.
