TORTUGA

Shifting to the next higher gear, ie, hi 2nd to low 3rd. As follows: Relax the pedal holding the Rpm to around 1300, double clutching as you go thru neutral with the main box. Once you drop the main box in gear 3rd, again holding the Rpm at around 1300 take the duplex to the low side raising the RPM to 1600 as you go thru neutral, once again double clutch as you go thru neutral. The time will come when taking the duplex to low you will gently push the rpm up toward 1600 as you move thru neutral without using the clutch and she will just fall in gear. Your RPM split will vary slightly depending or gear ratio, tire size and even from gear to gear within the box, but this is in the ball park. If the duplex wants to grind going into the low side of 3rd, let the clutch out with the duplex in neutral, give the pedal a smart alec lick, push the clutch in and drop the duplex in gear. Don't get in a hurry, the secret is to have the Rpm waiting for the shift at the anticipated rpm. Develop a rhythm. Don't get into the 2 sticks at this time yet. I always thought the most difficult shift to get down was low side of 4th to hi 3rd with one hand. have fun, Ray

Speed is dependent on top rpm, tire size, gear ratio, and transmission. For example an over the road B model was usually geared between 62 and 72 mph at 2100.
