Popular Post Freightrain Posted Monday at 05:24 PM Popular Post Share Posted Monday at 05:24 PM Was surfing Marketplace Saturday and came across an ad that caught my eye. RTLO 18913a $3500 Out of power unit that only used one gear. Low hours. Was super clean inside, sliding clutches all looked untouched. He has three, I bought one for my truck for when the 300+ gets installed. Overkill?? Absolutely. But won't have to ever worry about hurting it. And I am good with that. Double OD so it gives me longer legs. 6 2 Quote Larry 1959 B61 Liv'n Large......................

tjc transport Posted Monday at 05:49 PM Share Posted Monday at 05:49 PM why wait for the 300? i bet the 237 will be happy with that trans too. 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

Popular Post Freightrain Posted Monday at 07:18 PM Author Popular Post Share Posted Monday at 07:18 PM No doubt. It likes the Triplex splits but it is going to take some fab work to make it all fit and not sure I am ready for all that.....yet. I do have to finish my racing season. Have to work on mounting arrangements, may have to change clutch housing? Push clutch instead of pull. Now that I have something to touch and see I can start with working on a plan. Hard to do that with just pictures on a computer. I had him put a forward X cover on it instead of a rear. It will just be in front of my cross member on the floor that I put in when I rebuilt the floor. It gives me something to bolt seats into and stiffened everything. A rear cover put it just behind the cross member(pc of 1" sq tube). 3 Quote Larry 1959 B61 Liv'n Large......................

terry Posted yesterday at 02:12 AM Share Posted yesterday at 02:12 AM Are you sure it’s a double over or single overdrive? Terry Quote Link to comment https://www.bigmacktrucks.com/topic/75868-new-acquisition/#findComment-580977 Share on other sites More sharing options...
Freightrain Posted 23 hours ago Author Share Posted 23 hours ago It's double. .86 and .73(something like that). Per Eaton website. 2 Quote Larry 1959 B61 Liv'n Large......................

Popular Post Geoff Weeks Posted 18 hours ago Popular Post Share Posted 18 hours ago The newer Eaton's are like that. direct is one gear down-high. A overdrive front box with an underdrive splitter all plumbed for seamless progression (unlike the older underdrives). Gives 2 OD ratios, but not big jumps. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/75868-new-acquisition/#findComment-580988 Share on other sites More sharing options...
terry Posted 17 hours ago Share Posted 17 hours ago Sounds like a pretty good trans for what your doing, I like the gear steps in high range. Why not go with a pull clutch, or is there a linkage problem with that? Got to thinking B model clutch release set up probably won't work with a pull type clutch. terry Quote Link to comment https://www.bigmacktrucks.com/topic/75868-new-acquisition/#findComment-580994 Share on other sites More sharing options...

Either linkage or add a cable to the end of my existing pivot and loop around and attach to arm. Have arm hanging down and pull backwards. Either way is doable. Local friend has a B with an 8LL and said I can come up and see what he did. 1 Quote Larry 1959 B61 Liv'n Large......................

It depends on what can be found, and how much has to be bought, which way would be best. I wouldn't pay a premium for "common" in this case. As I have said before, I ran 14" organic clutches and they outlasted the engine builds. I was doing commercial and some heavy haul with mine. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75868-new-acquisition/#findComment-581005 Share on other sites More sharing options...
terry Posted 12 hours ago Share Posted 12 hours ago (edited) Yeah geoff i ran a 16 inch single disc clutch and a quad behind a 237 and had no problems for many years, but i was the only driver, and yes there was a 16 inch clutch, came off early V8’s. terry Edited 11 hours ago by terry Quote Link to comment https://www.bigmacktrucks.com/topic/75868-new-acquisition/#findComment-581015 Share on other sites More sharing options...

You may have said it in another post I am missing but what ratio is in your rear end? Are you planning on changing that too?

I know we were looking for something to replace the British bus 17" and saw Mack had one, but too much was different. Had to get our clutches air freighted in. Didn't have to do many but they were expensive when we did. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75868-new-acquisition/#findComment-581020 Share on other sites More sharing options...
Freightrain Posted 9 hours ago Author Share Posted 9 hours ago 2 hours ago, 67RModel said: You may have said it in another post I am missing but what ratio is in your rear end? Are you planning on changing that too? Currently 4.10. If I hadn't found the double over I was on the hunt for a 3.50 rear. The old Rockwell is thin pickings these days. Found a few but too pricey plus shipping from far away. Rear had 3.70 when I bought it but the old 673 didn't have the power to pull it so I swapped up to 4.10. Wished I had kept the 3.70 or bought a 4.10 instead of trading it off. Oh well. 1 Quote Larry 1959 B61 Liv'n Large......................

terry Posted 4 hours ago Share Posted 4 hours ago 4:10 rear with that overdrive that B will really scoot, i’m gonna guess,1600 RPM should be around 65 MPH ? terry Quote Link to comment https://www.bigmacktrucks.com/topic/75868-new-acquisition/#findComment-581048 Share on other sites More sharing options...
mrsmackpaul Posted 41 minutes ago Share Posted 41 minutes ago You blokes are pretty quick, mind you'll find it nice and quiet at 1600 rpm My bucket of bolts is pretty loud over 2000 rpm, 2100 is near 60 MPH and when I'm coasting along and the oils all hot it's ringing in my ears 1950 rpm is a lor quieter and at 55 MPH is much more relaxing Yeah very unfashionable and slow compared to blokes but we don't have traffic were I drive Paul Quote Link to comment https://www.bigmacktrucks.com/topic/75868-new-acquisition/#findComment-581051 Share on other sites More sharing options...
