Picked up a 6AT with some literature but thought I'd post up the basic info such as a CPL or two that might help someone- keep in mind that these motors came in several configurations and not all came equipped with the same parts- industrial, automotive and marine were the main variants. AFAIK the 6AT3.4 was a versatile motor promoted in a campaign to replace gasoline motors due to their higher RPM range and as you may know was orginally an ONAN design..
Also- don't use solvent (laquer thinner esp.) to clean off paint off of your engine tag- it will clean off all the info too! (OOOPS!)
6AT3.4
Engine No. 53120873
Advertised HP [email protected] rpm
Static timing .98 mm
Fuel rate @ advertised HP 50.33 mm3
CPL 1177
MFG date 9/89
Dry engine weight ( no flywheel or housing) 695lbs or 302 kg
Displacement 3.4l or 210 in2
compression ration 20.5 to 1
firing order 1-5-3-6-2-4
specs were for a turbocharged motor.
I will post turbo and injector info if needed later
Additional motor CPL - automotive (old UPS motor) 53111910
No other info available at this time.
I am trying to run this info through CNW and see if I can recover any of the info I wiped off the first motor, and the second as well.
The first motor had a Bosch ECU for the glo plugs and 3 of which were recently replaced. I am curious if they really need to run after combustion and will research how they are cycled. I have the Operation and Maintenance bulletin 3810377-01, Parts catalogue s (2-3884287-01 and 3884259), installation manual 3884538, A series engine familiarization 3387490, Engine installation drawings 3884538, Shop manual and bulletins 3810384-01.
I'm sorry but I don't have time to scan all of these but feel free see if you can still get this stuff from Cummins.. You can post up with questions but I don't get on here a lot.
Please post up with your 6AT info.
