Frame And Engine Numbers; Identification Numbers; Buying Spare Parts - Yamaha TDM850 User Manual

Frame and engine numbers

The frame serial number is stamped into the
right side of the steering head. The engine
number is stamped into the top of the crankcase
on the right-hand side of the engine. Both of
these numbers should be recorded and kept in a
safe place so they can be furnished to law
enforcement officials in the event of a theft. There
is also a carburettor identification number on the
intake side of each carburettor body, and a colour
code label on the top of the rear fender under the
passenger seat. The colour code label may also
contain the bike's production year and model
code.
The frame serial number, engine serial
number, carburettor identification number and
colour code should also be kept in a handy place
(such as with your driver's licence) so they are
always available when purchasing or ordering
parts for your machine.
The procedures in this manual identify the
bikes by model type (eg TDM) and if necessary
by production year. Note that the production year
does not necessarily correspond with the year of
sale or registration.
The model code number is very useful when
ordering parts for your bike and is linked to the
production year as shown in the accompanying
table. There should be a sticker on the bike's rear
frame section (usually visible once the seat is
lifted) which gives the model code number (eg
4TX4, meaning a 1999 TDM), the Yamaha
production code number, and a letter indicating
the colour code. The frame and engine numbers
can also be used to establish the production year
and model code, although these are not available
for post-1995 models. The accompanying table
gives model identification data for models
available in the UK market.

Buying spare parts

Once you have found all the identification
numbers, record them for reference when buying
parts. Since the manufacturers
specifications, parts and vendors (companies that
manufacture various components
machine), providing the ID numbers is the only
way to be reasonably sure that you are buying
the correct parts.
Whenever possible, take the worn part to the
dealer so direct comparison with the new
component can be made. Along the trail from the
manufacturer to the parts shelf, there are
numerous places that the part can end up with
the wrong number or be listed incorrectly.
The two places to purchase new parts for your
motorcycle - the accessory store and the
franchised dealer - differ in the type of parts they
carry. While dealers can obtain virtually every
part for your motorcycle, the accessory dealer is
usually limited to normal high wear items such as
shock absorbers, tune-up parts, various engine
gaskets, cables, chains,
