Pictures of L10 in MC8

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

Melbo -

Just an FYI - an exhaust brake in the exhaust system (commonly called a Pac-Brake), is nowhere near as effective as a Jake Brake on the engine itself.

The Jake creates far more braking power compared to the Pac, and experience has shown that the Pac-Brakes are more trouble-prone.

The Pac's ok for running around the flats, but if you start spending any real amount of time traveling over Rocky Top out West, you'll quickly discover the Pac-Brake's limitations.

BTDT.

Very clean installation of the L-10. . . compliments to the shop that's doing the work.

FWIW & HTH. . .

Melbo,


    Depending what model ZF you have it may have a retarder built into the tranny.

    FWIW

Allisons can also have either a output shaft or input shaft hydraulic retarder on them.  Good Luck, TomC

I have been forewarned about the exhaust brake and the mountains.

I have been told that the exhaust brake works fine up to about 35000 lbs.

I will see how it treats me on the drive home.

I will be driving through some mountains -- nothing outrageous but mountains none the less

I will post more pictures and a report of how it performs in about two weeks or so.

But I appreciate the heads up.

Melbo,

    Maybe I am the retarder one here and I really pray you have a safe trip.

   If you do have a ZF Ecomat II 590 to 602 or an Astronic it will have retarder.
   It is computer driven in the bus set ups, the ones in freightliners can have a
   hand controller. It usually isn't considered Kosher to have the exhaust brake on and then
   have the retarder kick in. If the retarder has been disconnected on the wire bar then
   do watch the engine RPM; an over rev will kick it into a higher gear (BTDT NOT good)
   I was also told there is a pressure over ride that will upshift the tranny also (haven't done that yet)

    FWIW please be safe

Thanks for the heads up I will check that out before I hit the road.

I just had the brakes all adjusted and a brake line replaced before I took the coach in for the transplant.

The purpose of the retarder and exhaust brake as you know of course is so that you don't have to use as much brake.

I hope everything works as designed -- I will post when I know.
