General description
The lock-out pins of the selector rods have the function of avoiding the shifting gears to be properly activated, avoiding situations like:
1 Gear overlapping (trying to shift two gears at the same time)
2 Gear shifting without a properly coupled/uncoupled planetary set
One may say that the lock-out pins of the selector rods substitute, at the same time, the “interlock” device existent in some gearboxes with a planetary set with detent plates, or other mechanisms that avoid improper shift of two gears simultaneously.
Important:
When assembling the pins (9) and (5), attentively observe their assembling position, since there is a chance that the pins may not have been assembled in the sameposition. Follow the exact position indicated on the figure.
“Interlock” function:
When activating the planetary set, the actuator pin (9) is inserted on the slots existent on the selector rod of the planetary set; with that, it lets pin (8) and all of the other pins (4 to 7) remain free for movement. In case that happens, meaning, the planetary set selector rod did not move enough so that pin (9) finds one of its slots, pin (8) is shifted to the right and blocks the actuation of all of the selector rods through pins (4 a 7). Thiswould be the “interlock” function of other gearbox models
Locking function
The selector rods (1, 2 or 3) also have slots, and when they are in neutral position, they leave pins (4 to 7) free. Whenactivating (for example) the selector rod from 3rd./4th. gears, pin (7)will leave the selector rod slot and will be pushed against pin (6),avoiding the reverse/crawler selector rod to be activated. Also,pin (4 and 5) will be activated, which will avoid the actuation of 1st./2nd. gears.
The same will happen to one of the other selector rods; when it isactivated, this will force its respective pin to be pushed, which will lockthe other pins, blocking the other selector rods.
