davehummell Posted February 2, 2020 Share Posted February 2, 2020 On my b model I have a straight 10 speed duplex and I can have a 720 triplex with a power take off for a good price. Will there be any changes other then the drive shaft length and new holes in the floor?

Should be a simple swap! terry Quote Link to comment https://www.bigmacktrucks.com/topic/60798-duplex-to-triplex/#findComment-441825 Share on other sites More sharing options...
theakerstwo Posted February 2, 2020 Share Posted February 2, 2020 The duplex will be a single disc clutch but the triplex could be double disc which uses a different flywheel housing.The housings will interchange but engine mounts need moved.The triplex may be single disc but when you look at the housings you will see the difference. 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/60798-duplex-to-triplex/#findComment-441826 Share on other sites More sharing options...
davehummell Posted February 2, 2020 Author Share Posted February 2, 2020 I understand there is a difference on the thickness of the bell housings and this one has the same arm setup coming out of the housing to use on a push throw-out bearing. My trans is jumping out of 10th gear on a climb and when floating with no strain on the drive line it gets old holding on the shift lever all the time just in case it jumps out. I am going to run it this summer but I am going to change it next winter. I understand with this tranny you get 13 speeds and high gear is overdrive with 3.90's it should cruse on rt.81.
