Lmackattack Posted yesterday at 09:18 PM Share Posted yesterday at 09:18 PM I want to order a new clutch for my 77. It has the 285 maxidyne with a rebuilt 12 speed that i will be installing soon. My build sheet says it had a CL75 when new. Engine is original to the truck. What clutch should I look for?. I know nothing about them besides how they work. Thank you Quote Link to comment https://www.bigmacktrucks.com/topic/75504-mack-cl75-clutch/ Share on other sites More sharing options...
Joey Mack Posted 22 hours ago Share Posted 22 hours ago Have you considered a flywheel from an E-7 ? Its 15 1/2", and you can get an Eaton Easy Pedal clutch. You can also get it in H.D. more springs and paddles. 9+7... Ive done a few. Lets see what the guys say..

Lmackattack Posted 21 hours ago Author Share Posted 21 hours ago I have not considered anything because I literally know nothing about what clutch fits or can be retrofitted. I'm just trying to keep it simple as this truck will never see more than 285-300hp. I just want a bolt on and go. If there is a reason to swap flywheel I will but if it's not necessary I wont.

Joey Mack Posted 21 hours ago Share Posted 21 hours ago Fair enough. No need to swap if it is not going to be a workhorse.. Quote Link to comment https://www.bigmacktrucks.com/topic/75504-mack-cl75-clutch/#findComment-575471 Share on other sites More sharing options...
Joey Mack Posted 21 hours ago Share Posted 21 hours ago I had the impression that you wanted a different clutch than a CL-75. Quote Link to comment https://www.bigmacktrucks.com/topic/75504-mack-cl75-clutch/#findComment-575472 Share on other sites More sharing options...

If they make a better modern clutch that simply replaces a CL75 I'm all ears. But just don't want to have to swap flywheel or other expensive parts if it's just to get a higher rated clutch if it will never see more than 1200 ft lbs 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75504-mack-cl75-clutch/#findComment-575473 Share on other sites More sharing options...

Joseph Cummings Posted 8 hours ago Share Posted 8 hours ago I've never seen an ENDT676 in an R model of that vintage not have a standard Spicer Angle Spring. WTF is a CL75? What does this thing look like? Does it look like this? 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75504-mack-cl75-clutch/#findComment-575492 Share on other sites More sharing options...
Geoff Weeks Posted 7 hours ago Share Posted 7 hours ago That is what the little on the internet suggests, but I have no experinace converting "Mack" model number to others.

Joey Mack Posted 7 hours ago Share Posted 7 hours ago I have cross reference material in my shop, but i would have to sift through dozens of books and hundreds of paper buletins.. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75504-mack-cl75-clutch/#findComment-575496 Share on other sites More sharing options...

Real easy on the flywheel and pressure plate also. If it holds under full load, why do you need more than that? 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75504-mack-cl75-clutch/#findComment-575498 Share on other sites More sharing options...
