1986 102A3 - Unit Number Location

[jraynor]

Hello everyone,

As I'm sure everyone may wonder as they look at the maintenance manuals and see the effective unit numbers for which drawing applies to their bus, where can one find the unit number for their specific coach? Specifically mine is a 102A3

Thank you,

On my 1985 model 96a3 there is a riveted plate on left side of the entrance stairs that provides salient info.
Good luck!

Two number plates with data. One in the entrance and the second is in the engine compartment on the front bulkhead.

Would the bulk head be there the wall is on the inside of the bus? Just trying to orient the correct place to look

Thank you,

On the bulkhead in the engine cooling blower compartment, underneath the surge tank.

is unit number and serial number the same thing?

Jonathan -

After re-reading your original post, yes, the unit number and serial number would be the same, since 17-digit VINs became required starting in 1981.  (MCI might consider the last four/five of the VIN as the unit number - ask them.)

Thank you, Now i can just question what what applies to mine when i look at shematics

Gotta disagree with you RJ,  if you look at the MCI delivery list you will see that they have a fleet #, a serial #, and a unit # for most of the buses listed there. The numbers are not the same.

At least this is the case for the older buses, don't know about the "newer ones".   I see that he was asking about a 1986 bus, so my comments probably don't apply!

Here is an update for everyone. While I was exploring around in my first cargo bay accessing the AC supply blower fans, I stumbled upon these numbers stamped into the front wall just left of the access door below the door spring "5682" which is the last 4 of my VIN. Pretty interesting find

Not sure of what year they stated this, but mci started using the end of the vin as the unit number. My mc8 had different vin and unit numbers, but my dl3 uses the last 5 of the vin as the unit number.
