Hard Shifting And Oil Leaks - Ratchet Top Tune Up - Tech STC
|
The top of the pawls have a slanted top and a machined shoulder. When the shift linkage is pulled or pushed, the pawl carrier rotates, allowing the edge of the pawl's shoulder to rise and engage one of the notches of the shift gear shaft. The continued rotation of the carrier rotates the drum, moving the shift forks to the next gear. Once this movement is complete, the carrier returns to the central position. Only one pawl works at a time; one pawl for upshifts, the other obviously for downshifts. While one pawl is pressing into the notch on the shift gear shaft, the other pawl is being pushed down into the pawl carrier out of the way of the shift gear shaft, springing back up once the movement is completed. A slightly sharp or crisp corner at the top of the pawl aids in engaging the shift gear shaft notch. Here we are touching up the top edges on a hard stone with some 3-in-1 oil. View Related Article
