I have this same problem right now, are these special o ring and snap rings that need to be purchased from Mack? Going to take apart just wondering if I needed to order a rebuild kit or if I can just replace orings from a oring kit? Thanks

How much?

Can you replace just the sealed bearings in these, Or is it the complete hub assembly that has to be replaced?

Hello, I bought this service manual on ebay , and according to this it looks like all engines have the dynatard cam in the E6's, just giving an update, thanks to everyone for posting and helping.

O.K. thanks D-Day this helps more to understand how the dynatard works

O.K I Have the other complete engine that I was using everyday up until October when it spun a bearing or something, So I have everything , so I guess I could see if it will work, I am just trying to keep from having someone change camshafts if possible.

O.K. Thanks everyone for the quick replies, the only reason I was wanting to use dynatard is because I have one on the e6 that spun a bearing, and I heard its hard to find a Jake brake for a E6. Have heard someone mentioned that in later years all mack engines had the dynatard cam regardless whether one was installed or not, but don't know if that is so.

O.K., So is there any way to tell from looking at anything under the valve covers if it would have the right cam for Dynatard? Engine is a 1989 EM6 300L 4 valve .

I can't even find the B code on my E6 350 and it has a Dynatard , unless I'm looking in wrong place. would the code be somewhere besides the tag?

O.K. Thanks everyone for the fast replies, I'll check the engine tag and see if it has a B on the tag in the engine family.

O.K I was thinking about putting a EM6 300L in my R model and I didn't know if the dynatard from my E6 350 would work on it.

Can a Dynatard be installed if engine didn't come out with one?

O.K. thanks Mark T

O.K. thanks everyone for the quick replies! Yes this truck came from a company so treated worse than owner operator would treat it more than likely, so either one of the clutch brakes posted (Euclid EB201500 , 127200) will fit my Maxitorque 10 speed? Thanks , Denny

Hi, I have a 2006 Mack Granite with the Mack 10 speed multi reverse transmission, I just recently bought this truck and its hard to put into gear from neutral, so I crawled under to look at the clutch brake, and I do not see a clutch brake. Is it possible that it has came apart and fell out? Does the Mack transmission use the same type clutch brake as a Eaton? And what is the input shaft size , 1 3/4"? Thanks
