Freightrain Posted 10 hours ago Share Posted 10 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 6 hours ago Share Posted 6 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 5 hours ago Author Share Posted 5 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 4 hours ago Share Posted 4 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 3 hours ago Share Posted 3 hours 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 1 hour ago Author Share Posted 1 hour 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......................

D-Day Posted 12 minutes ago Share Posted 12 minutes ago I have always thought the flywheel housing depth was the same it was the bell housing and input shaft that changed in dimension for single or double plate clutch but I can measure it there are a couple of old 13 speed road rangers here small size with air actuated clutch brake they had a little push button on the shifter the bell housing and input shaft is where it gets tricky to locate the right input shaft length and bell housing depth with Mack side mounts Quote Link to comment https://www.bigmacktrucks.com/topic/74791-flywheel-housing-for-2v/#findComment-562586 Share on other sites More sharing options...
