Freightrain Posted 9 hours ago Author Share Posted 9 hours ago My truck is together so there is no way to measure anything. Oops, I see I typed #2 up above. That wrong. I don't need mounts on the bell housing. I am going to have to fab up something else, maybe something underslung near the back of the box? That will have to be done after I get a transmission picked Quote Larry 1959 B61 Liv'n Large......................

Freightrain Posted 9 hours ago Author Share Posted 9 hours ago Something a long these lines? This for 18 spd. https://www.vanderhaags.com/detailview.php?manufacturer=fuller&model=rtlo18918b&inventorytype=transmission-clutch-housing&partnumber=K3672&wcf=parentmodel I guess you have to buy it for the particular model transmission? If I have a choice, I am going for something with a double OD. Quote Larry 1959 B61 Liv'n Large......................

Geoff Weeks Posted 8 hours ago Share Posted 8 hours ago (edited) I THINK this is what you are looking for: Nodal mount Push and pull Clutch Doesn't say what model trans it came off https://www.heavytruckparts.net/item/Mack/-/Bell-Housing/297005/1/83669829 What I remember, but DO NOT go off my memory alone, that the newer model Roadranger trans bells are different than then earlier (pre RLO) -6 and older transmission clutch housings, although they look similar. edit: it doesn't look like the lower bosses are machined out for a push clutch, the bosses are in the casting but they haven't been machined.

Geoff Weeks Posted 8 hours ago Share Posted 8 hours ago Found this: https://www.eaton.com/content/dam/eaton/products/transmissions/vehicle-transmissions/eaton-transmission-clutch-housing-selector-cmt1540-en-us.pdf It seams to imply that push and lower pull are NOT the same on the cross shaft (learned something new) and I can't find a push nodal mount for the older transmissions. SO I may be wrong. That said if you can fit a double disk pull flywheel, the trans with the nodal mount shouldn't be hard to come by.

Geoff Weeks Posted 7 hours ago Share Posted 7 hours ago Wooo hooo! I found what you need to know! https://www.redramgear.ca/wp-content/uploads/2015/05/eaton-fuller-transmission-identification-guide.pdf A 6064 is a nodal with symentrical mount bolts in aluminum with both push and pull A 4373 is a nodal iron for push clutch only A 4232 is a iron nodal in SAE #2 Hope this helps Quote Link to comment https://www.bigmacktrucks.com/topic/74791-flywheel-housing-for-2v/page/2/#findComment-562645 Share on other sites More sharing options...
Geoff Weeks Posted 7 hours ago Share Posted 7 hours ago Hum, 6064 is listed as both nodal and non nodal and any pictures I see are non nodal? So not sure we are out of the woods yet.

Freightrain Posted 7 hours ago Author Share Posted 7 hours ago I can put a pull clutch in, just have to revamp my linkage under the truck. It's been done before. I am just looking around to see if I can find the unicorn that will make this a bolt in. On a side note, I also need to look for a forward top cover. Just to help move the shifter more forward where it is with original transmission. That link you posted is awesome information. Kinda confusing but will need to do some reading and soak it in.

Geoff Weeks Posted 6 hours ago Share Posted 6 hours ago Top cover should be any problem RTO is std cover RTOF is foward set shifter cover. I assume you're looking to make a RTOOFxx5 or6 13? I am getting no hits on any of the numbers other than the 6064, and that is suspect for being a Nodal mount. From what I have read, you don't want anything new than a "6" trans and they are now so out of date that they aren't what show up most of the time. 5 series is "course gearing" 6 series is "fine gearing" 7 is the start of the low inertia series transmissions. I take it you are looking for a .68 top O/D gear?

Geoff Weeks Posted 5 hours ago Share Posted 5 hours ago This says it is for Mack, seams to be double bushed for both over/under but listed pull only https://www.ebay.com/itm/292528684947 Quote Link to comment https://www.bigmacktrucks.com/topic/74791-flywheel-housing-for-2v/page/2/#findComment-562650 Share on other sites More sharing options...
Geoff Weeks Posted 5 hours ago Share Posted 5 hours ago (edited) This one is nodal, but the bottom bosses are not machined out. The above post with the .pdf has the drawing with the dimensions to locate the lower shaft for push applications. https://www.vanderhaags.com/detailview.php?manufacturer=fuller&model=a-4456&inventorytype=transmission-clutch-housing&wcf=model If you have the ability to do the machine work or know someone who does, you could make a push bell with nodal mount with the info we now have. It would appear that Mack uses the symmetrical nodal mount from what I can glean from the E bay listing.

Geoff Weeks Posted 5 hours ago Share Posted 5 hours ago This one has the correct drilling of the lower shaft for a push type clutch, but unfortunately is not nodal mount. https://www.ebay.com/itm/296632014527 If you look carefully at the pictures you can see the lower shaft is toward the transmission side of the housing more than the upper. Flipping between the last two I posted, I think one could locate and machine the nodal mount one to take a push clutch shaft. That is as close as I have come.
