Bigdogtrucker Posted May 28, 2012 Share Posted May 28, 2012 My C600 has a 10 speed direct trans.The main stick is a bit sloppy,can be tough to find second.Feels as there is no detent spring.It shifts good otherwise,what would be needed to fix this?Also just curious as to what other gearbox's would be a direct bolt in?

Freightrain Posted May 28, 2012 Share Posted May 28, 2012 Not sure, but I would bet any duplex/tri/quad would physically bolt in. The only problem I see is the tri/quad has a longer back box so the driveshaft would be shorter(meaning those would not be a direct bolt in---but doable).

theakerstwo Posted May 28, 2012 Share Posted May 28, 2012 Most triplex and duplex have a twin disc clutch. If the duplex has a single disc some times the frame mounts need moved because the bel housing is longer on the twin disc.I did one about 8 year ago and had the parts truck here.So i did pull the frame brakets out of one and use on the other with changing trans frome a single to a twin disc.

Maddog13407 Posted May 28, 2012 Share Posted May 28, 2012 i know in most b models a triplex will bolt right in but a quad with the emergency brake drum wont without the special cab mount crossmember. this can be remedied by adding maxi brakes and removin the e brake off the transmission and it will fit. most b models had the cab mount crossmember reversed and an angle iron sort of bracket off that to bolt the cab to that had the quad in it. i asume C models are about the same Quote Link to comment https://www.bigmacktrucks.com/topic/25332-10-speed-duplex-questions/#findComment-121462 Share on other sites More sharing options...
