Pictures of L10 in MC8

[Melbo]

Here are a couple of pictures of the dry fit of the L10 into my MC8

That is real pretty. It should scoot you right down the road.
Was the engine craddle custom made? Looks new too.

[Melbo]

The engine cradle was out of an MCI but was cleaned up and the engine mounted before it got slid into place.

Great project & photos Medbo!

What trans?

Drive shaft shorten?

Does rear channel & bumper need to be move rearward?

Keep project reports coming in with photos.

Thanks for your update.

      nice pix; looks like they used a stock cradle (8V92)  but moved it towards the back of the bus.. 
   my solution will be slightly different because I used the standard cradle and added the bottom mount..
    Have you decided on a pulley yet I had one made with a single C groove at 9.4 inch diameter; same as the original Detroit. Can give you the info if necessary.  Had to be machined to allow for the Cummins hub which has metric dimensions and oddball spacing on the holes.   
     FYI  that motor has a fan hub so it was transverse mount in a bus (for example in a Gillig) or in a truck..  Depends on the CPL. Thats on the manufacturers plate or the first 4 digits on the fuel pump.   most transit  buses  are fitted with   1994 CPL and run 270HP.   yours may be different.  Cummins has a website and for a fee you can have the engine seriel number looked up and find out when it was made and the history if the company had Cummins service the motor.        FWIW.
    Looks good hope it works well for you .. 
        Happy bussin     Mike
     P,S.    If you have the CPL number I can look it up in a cpl book and tell you what the published HP is for that CPL.   CPL is certified parts list which tells which pistons, cam, injectors ,turbo etc. are required for that particular motor.  If the motor has to be rebuilt  the mechanic uses that number to get the parts..  The fuel pump is set up to deliver the HP listed for that CPL .   Any dealer or shop can do the same.     Mike

Melbo,

Great project.  What Jerry said/asked.

Also, what is the HP?  Why did you select Cummins and that model of Cimmins?

Thanks,

John

Mike, What bus are you putting a Cummins in ? Is it up and running?  Thanks TomY

[mikelutestanski]

Tom Y    The engine is an L10 270Hp cpl 1994 mechanical.  The tranny is an Allison B400R 6 speed  computer control (WTEK II)  with throttle position sensor.
   I replaced the lower bearings and cleaned up the engine . This engine came from a Gilleg in Atlanta.. The tranny came from an orion 1 transit
      Here is a pix of the test stand for the motor/tranny.   I wanted to have the motor and tranny running so that I had a baseline to start from. Everything worked on the stand. 
          Working on the cradle and mounts now.  Hope to have it running in a month.

     The bus is a 1972 MCI 7.    changed the diff. to 4.63 to accommodate the double overdrive. 
            Happy bussin.    Mike
       

[Sojourner]

Hi Mike......where did you get 4.63 diff from what vehicle?

I have 3.86 Meritor rear axle assy in my MCI-8 but need change to higher ratio number like you said when I ready to swap engine & trans.

Is this L10 270hp is non-turbo?

Thanks for update.

Mel,
The progress is looking great!  That combination should give you excellent mileage.  Do you have jake brakes on it?  What are you going to do for over the road air conditioning?

Mike, She sure looks purdy, real purdy. It's nice to start out with a nice clean looking engine compartment, nice work and thanks for the pictures.

I should clear up a misconception -- I am having this done -- I am not doing it myself

The tranny will be a ZF and the complete setup will include an air throttle and exhaust brake ( no jake )

The project should be completed about the first of march.

For over the road air I use the front rooftop AC running from a 4024 inverter

The rest of the particulars I don't know but can find out if necessary.

Hope this helps

Here is the most recent picture I have as the project progresses.

As you can see the engine compartment is painted and the engine is in the place it belongs.

The plan is still to have it up and running the first part of March however we have gotten side tracked by some problems we have with the steering we are working on.

As you can see it still needs the intake and the exhaust however some of that may have already been installed because this picture is a little more than a week old.

These pictures are proof positive at the nice fit the Cummins L10/M11/ISM (all the same block) will have in a bus.  Whereas the Detroit Series 60, Cummins ISX or N14, Caterpillar 3406/C15 are so huge that you have to modify the floor to get them in-and they can weigh up to 1,000lbs more then the Cummins L10.  One more nice thing about the L10 is that it has a air to water after cooler so you don't have to design that into the radiator system.  The L10 was limited to maybe as much as 350hp and 1100lb/ft torque (like a 6V-92TA) but getting much better mileage than the 2 strokers (L10 also weighs about the same as the 6V-92TA).   Course if you really want to have a hot rod, you can get the more modern ISM that can be made into a 500hp 1550lb/ft torque monster that will have close to the pulling power of the Series 60 without the size and about 500lb lighter.  Good Luck, TomC
