Joey Mack Posted 2 hours ago Share Posted 2 hours ago I see the inspection cover is on top, on the trans. Where is it on the new bell housing? Just curious...

Entire transmission is below the cab floor so that should not be an issue. Quote Larry 1959 B61 Liv'n Large......................

I will have to fab up mounts to get up to the Eaton mount area. The frame mount ledge is about the same as upper mount holes in Triplex. The Eaton is way up compared to those. The pattern is completely different between each . See sketch. Quote Larry 1959 B61 Liv'n Large......................

Yes, but what I see of the nodel mount is above the transmission.

Freightrain Posted 55 minutes ago Author Share Posted 55 minutes ago The top of the bell is still just below the floorboard so the mount will be going down and back from the mount point on bell. I don't see an issue with clearance. Time will tell, I have a welder....it will all fit. 1 Quote Larry 1959 B61 Liv'n Large......................

mrsmackpaul Posted 33 minutes ago Share Posted 33 minutes ago I have noticed in Australia when RoadRangers/Eaton are installed in Macks aftermarket, a rear transmission mount is also used, these range from a propper engine mount rubbber deal to a section of leaf spring out of a car or pickup as you blokes call them These might be only 2 or three leaves, I wonder are they really needed or not ?

I don't see an issue with clearance. Time will tell, I have a welder....it will all fit. Not trying to say it will not work, just wanted to point out somewhere to check. The new mount is in a "different area code" as you put it, so needs checking, which it sounds like you have done. New things in different real estate is always a concern.

Joey Mack Posted 10 minutes ago Share Posted 10 minutes ago Paul.. The single leaf spring at the rear of the main box was used here as well. Ive seen it in Ford's and Freightliner's, I think Int.'s also.

Paul Generally, here if the rear mounts are on the engine 1/2 of the bell, a rear transmission "leaf spring" type or rubber bisket mount is used. On set-up's where the rear mount is on the transmission 1/2 of the bell (thinking Volvo/White) then there is nothing at the rear of the transmission. It may have something to do with how much weight is cantilevered off the back of the bell housing, esp when aluminum housing are used.
