MCI Parts Cross-Reference

[RJ]

Hey all -

Does anybody know if the MCI rear brake relay valve (4R-11-1) and the inversion valve (4B-29-1) have cross-reference numbers to off-the-shelf HD truck parts?  Or are they bus-specific?

I was going to call Luke, but he'd already gone home for today. . .

TIA,

RJ

RJ,277340RX for the inversion valve that can be  taken apart and cleaned with new seals,a standard R-8 for the rear like the286370X

good luck

Clifford -

Thanks for the numbers.  The shop where Tortoise is parked actually had both of them in stock!  Plus the new DD3 chambers came in today, so progress has been made.  Plan is for them to start either Thursday afternoon or Friday.  I also found in the back of my storage unit a brand new Bendix AD-9, so they'll pull the old AD-2 for this more current model - and they even had the bracket kit for converting sitting on a shelf! 

FWIW & TFYH. . .
