Freightrain Posted 8 hours ago Share Posted 8 hours ago How easy to get? Part number? Someone have one laying around close to NE Ohio? I need to change out my single disc flywheel so I can upgrade my transmission. I have a flywheel already. Quote Larry 1959 B61 Liv'n Large......................

D-Day Posted 4 hours ago Share Posted 4 hours ago I have one I think it's on a 711 not sure it's the same but it did have a twin disc push type clutch and the starter is on the right, I am quite a good distance from NE Ohio in western NC Quote Link to comment https://www.bigmacktrucks.com/topic/74791-flywheel-housing-for-2v/#findComment-562563 Share on other sites More sharing options...
Freightrain Posted 3 hours ago Author Share Posted 3 hours ago Interesting. I'm not versed in all this so it seems strange it was a twin disc? My 237 came from a fire truck and was a single disc. I want to upgrade so I can put a 13 spd in it. Quote Larry 1959 B61 Liv'n Large......................

Geoff Weeks Posted 3 hours ago Share Posted 3 hours ago Larry, I think you'll want a pull clutch, but I have no idea if the bells are the same or not. Are you looking at an Eaton or other mfg trans or a Mack?

Geoff Weeks Posted 1 hour ago Share Posted 1 hour ago (edited) They can be made for a push clutch, but then you loose the clutch brake. Is the bell you have now made to SAE spec's? If so, I think you can use the single disk set-up with a push front bearing retainer on the trans. That would have to be "special ordered" as very few use a push clutch. The Bell on my 9 speed has the holes below the input shaft for a push clutch yoke.

They made a clutch brake for a mack push clutch, it had a lever that went down and pushed a disc against the counter shaft.

Freightrain Posted 3 minutes ago Author Share Posted 3 minutes ago Heck, If I could just use my single push and get a shorter input for a 13 spd that would make things a HUGE amount easier. It would be a bolt in. I have a 2" input currently. Only reason is my triplex is just gone and want something that is smooth, quiet and stays in gear. I just need to find a box that has side mounts for a Mack application. I could even live with a 10 spd if I had to. Just needs OD. Quote Larry 1959 B61 Liv'n Large......................
