Willie dog Posted October 30, 2015 Share Posted October 30, 2015 (edited) I'm new to Mack trucks and was wondering about the shift pattern on a b 42. It's a six cylinder gas engine. It has two sticks. The shift tag above the windshield shows five speeds. Do you run through all five gears then shift the second lever and run through all five again? I'm a newbie so please forgive my ignorance.

Freightrain Posted October 30, 2015 Share Posted October 30, 2015 If it is a 10 speed (duplex) you split each main gear. Now that is in a fully loaded situation. You can skip gears if it won't lug the engine.Get on YouTube as there are plenty of B model videos showing shifting technics. 1 Quote Larry 1959 B61 Liv'n Large......................

Willie dog Posted October 30, 2015 Author Share Posted October 30, 2015 Thanks for the information. When this thing is done the only weight it will carry is it's own. I think it will have an easier life than before. Quote Link to comment https://www.bigmacktrucks.com/topic/42430-shift-pattern/#findComment-309377 Share on other sites More sharing options...
other dog Posted October 30, 2015 Share Posted October 30, 2015 No need to be so modest Larry! Here you go- I think there's a better version of this, but this is the first one I found.

Freightrain Posted October 30, 2015 Share Posted October 30, 2015 Can't link stuff while on my phone. How come you didn't link your video??Few people have dropped off YouTube so videos arent there anymore. Guess I need to load them myself someday?

Maddog13407 Posted October 31, 2015 Share Posted October 31, 2015 I dunno, that old B42 might still need every gear split, even empty...... Quote Link to comment https://www.bigmacktrucks.com/topic/42430-shift-pattern/#findComment-309444 Share on other sites More sharing options...

Maddog13407 Posted October 31, 2015 Share Posted October 31, 2015 one closest to you on the smaller flathead gas jobs is the main. only ones that were different were the rare few that had a spicer or brown 3 speed auxillary Quote Link to comment https://www.bigmacktrucks.com/topic/42430-shift-pattern/#findComment-309477 Share on other sites More sharing options...
Willie dog Posted October 31, 2015 Author Share Posted October 31, 2015 Thanks maddog. The thing hasn't been delivered to my shop yet and itching to get familiar with it. Right now the way it is I wouldn't drive it across the street, but I will around the lot to get familiar with the workings.

Freightrain Posted October 31, 2015 Share Posted October 31, 2015 Twin stick pappy is good. I hear about having both in neutral like pappy. I start in 3rd and it is not good to have them both in neutral then. Even pappy only does it in 1 and 2nd gear. After that he only shifts one at an time.
