I have two 748 engines, the first is in my 2000 748 and the second one I bought to rebuild.
I believe they are both year 2000 engines.

Numbers are:
1/. ZDM 748W4014464
2/. SB 3Y014799

Questions are:
1/.why are the engine numbers so different?
2/. Which engine was built first?

The reason I ask is the second engine does have the later steel plug in the crank oil gallery and the first one as it's still in the bike I don't know and Ducati can't tell me.

Thanks Brad

I'm surprised it's a US motor too as I bought it from a bloke in Melbourne last year. ( looking inside at how trashed it is makes me think it could be one of Tye's old ones :) )

They did change from alloy to steel plugs in 2000, just they didn't record the change point so it's like russian roulette.
When I asked Ducati Australia about the #1 motor they told me the only way to find out is open it up.

10 nth digit is the year digit so your ZDM engine number is 2001.
Not so sure about the other number but
The letter Y in your other engine number is for the year 2000. So the first is the newest. probably.

Character 10: Model year code where,


1971 = 1 1981 = B 1991 = M 2001 = 1
1972 = 2 1982 = C 1992 = N 2002 = 2
1973 = 3 1983 = D 1993 = P 2003 = 3
1974 = 4 1984 = E 1994 = R 2004 = 4
1975 = 5 1985 = F 1995 = S 2005 = 5
1976 = 6 1986 = G 1996 = T 2006 = 6
1977 = 7 1987 = H 1997 = V 2007 = 7
1978 = 8 1988 = J 1998 = W 2008 = 8
1979 = 9 1989 = K 1999 = X 2009 = 9
1980 = A 1990 = L 2000 = Y 2010 =A

Just to add to the confusion, here's the engine number decoding from the Owners Manual. So it appears that #2 isn't a US Market engine.


Ducati uses different coding for different markets. Generally the engine number encodes engine displacement, number of valves, cooling type, fueling type and build number.

Examples

SB8 R 000001 US 1994 916
SB8 S 000001 US 1995 916

ZDM 888W4 000001 French 888
ZDM 916W4 000001 Euro, Australian 916
ZDM 916W4B 000001 French 916
ZDM 748W4B 000001 Dutch 748R

ZDM = Ducati, 916 = 916cc capacity, W = water-cooled, 4 = 4 Valves

ZDM 904A2C 000001 means 904 = 904cc A = air-cooled, 2 = 2 valve, C = carburated

Starting this one up again since I got a related question.

I can not find it online, but exactly what digits does clarify if the engine is from the US?

A buddy of mine got a 999S engine from 2004 - as he was told. But it can be verified by the engine number. ;)

It is: UB54009823

- does the UB5 means from US
- the "4" = 2004
- the rest = production no?

Have a 2006 MTS 620 Standard with what I was told by the first owner is a 750 replacement motor- UA26022294. I bought a clutch pack that was supposed to fit both motors but discs were 1/4" too large and stack was 16mm short. The inside of my basket is 133mm and height is 53mm. Have not heard back from Oregon dealer on which clutch to order.
Any advice on which clutch pack to order? Thanks.

This doesn't make sense. A 750 engine would have come from a Monster or an SS. And would be too wide at the swingarm pivot point to fit into the MTS frame, or to fit the swingarm onto. Most people won't do the work just to put a 750 in...

I know because I put an 800 Monster engine into my 620 MTS. We had to machine a little off each side of the swingarm area to make it fit. And the 800 has the APTC clutch.

Received the Adige DU-112 clutch kit today and the dimensions are correct for my basket. It is listed as an original replacement for 2004-on 620,696 and 800. While you're here am not sure if the seller was BS-ing me that this motor will go 12k miles between valve adjustments. It has over 40K on it and is within 1k of his recommended interval and it runs strongly. What is your advice?
