80 5C With Cummins L10 in Progress

« on: April 04, 2011, 12:55:21 PM »

I have been gathering parts for a couple months now. So the new tranny Allison SP3200 is mounted. May be a month before all is done to try. The engine and tranny are in, but checking to see if I want to make changes to the fit. Need a longer drive shaft for sure. This setup will use 5 speeds with 5th an .74 overdrive. If this does not fly the 740 is close by.   Tom Y

That is a very interesting photo, I see a lot there!  I like the stand to help guide in the engine.

Tom, isn't the 3200 SP a military spec transmission ? I had a chance to buy a pallet with 4 of those at a auction at Ft Hood but I didn't know anything about that model so I passed should have spent the 800 they sold for huh

good luck

Yes, You should have. I paid a lot more than that. That's my motto buy high, sell low. Mine was for a Spartan chassis, new never ran Gen 4. Part of the RV industry crash.

The 3200SP, MH, EV are all the same transmission rated up to 450hp and 1250lb/ft torque.  The 3000 series has a little different gearing then the 4000 series.  The 3000 is- 1st-3.49, 2nd-1.86, 3rd-1.41, 4th-1.00, 5th-.75, 6th-.65.  The 4000 is- 1st-3.51, 2nd-1.91, 3rd-1.43, 4th-1.00, 5th-.74, 6th-.64.
It is important to know that the 450hp 1250lb/ft torque is thee highest rating this transmission can tolerate and have a decent transmission life.  The ISM you're using can go as high as 500hp and 1550lb/ft torque.  Be sure you set the parameters on the engine not exceed the 1250lb/ft torque, and everyone will be happy.  Good Luck, TomC

Tom C, I am running a L10 330HP and 1250 ft lbs. So I hope this will work. If not I am saving the old parts for a while. Tom Y

It looks like an electronic engine.  I know the highest L10 mechanical was something like 330hp and 930lb/ft torque.  Hopefully this is electronic so that the trans will work correctly with the engine.  Good Luck, TomC
