Briggs and Stratton engines are identified with a MODEL, TYPE and CODE number system and take the form of the example below.

• The MODEL number is either 5 or 6 digits which may contain letters
• The TYPE number is 4 digits followed by an extension of 2 digits. Letters may be used in the extension
• The CODE number is the machine's serial number. The first 2 digits are the year of manufacture
  (the example above was made in 1999)

The numbers can be in a variety of locations depending upon the engine but are generally to be found either:-

• Stamped into the front, top or side of the main cowling
• Stamped into the plate over the exhaust
• Etched into the plastic cover
• Stamped into the rocker cover on an OHV engine
• On a transfer, sticker or riveted plate on the main cowling

When you click the Briggs and Stratton parts illustration link at the top of the page, the Illustrated Parts List page will open asking you to enter the MODEL and TYPE numbers of your engine.

Enter the 5 or 6 digit MODEL number into the first box, and the first 4 digits of the TYPE number into the second box as shown in the example below.

An engine with the following details:

Model	Type	Code
12F802	0637 01	99070759

Would be entered as follows:

Then click the GO button

Your parts illustration pdf document file will then be found (if you do not have a pdf viewer, click the Acrobat download link and follow the instructions to download the pdf reader)

Click on the pdf icon where it says:

"View or Buy Online"

Your parts illustration document will now download for free(this may take a while depending upon you connection speed)

Your downloaded parts illustrations are a series of pages within one pdf document. The righthand scrollbar is used to scroll through the pages.

Generally, page 1 is an index detailing which page each section is on.
Find the page showing the part that you need and then locate the part.

The part will have a reference number next to it. Make a note of this number.

You now need to convert this reference number into the correct part number.

The part number index will be listed in one of two ways:

1. Each illustration has its corresponding list of numbers below it
2. All of the numbers are listed on pages at the bottom of the whole document

...would be part number 802574 and decription Armature-magneto

Sometimes illustrations show a number of choices for a part, each with a different reference number.
Often the alternative reference numbers will carry a letter.

4, 4A, 4B etc.

Carefully compare the picture with your part to see which setup you have.

The description in the part number listing will also help to correctly identify it.

for example:

REF.NO.  PART NO.     DESCRIPTION
4       493279   Sump-engine 4A     493365   Sump-engine(aux pto)

Where item 4A (493365) has an auxillary PTO drive shaft on the side.

(see also "Used on Type" and "Used Before/After Code")

Some parts references give a number of alternative part numbers depending upon the engines TYPE number.

For example:

REF.NO.  PART NO.     DESCRIPTION
83   691778	Shaft-auxillary drive
	----------note----------- 690522 Shaft-auxillary drive used on Type Nos. 1170,2950,2951. 690527 Shaft-auxillary drive used on Type Nos. 1141,1172,1516.

In this example:

• An engine with the TYPE number 2950, would use part number 690522
• An engine with the TYPE number 1141, would use part number 690527
• An engine with none of the listed TYPE numbers, would use part number 691778

(combinations of type and code dependant alternatives are often encounered, work out what you need in careful, logical steps)

"Used Before/After Code" part choices

Some parts references give a number of alternative part numbers depending on the age of the engine, or it's CODE number.

For example:

REF.NO.  PART NO.     DESCRIPTION
802   695267	Cap-End (used after code date 00040600) ----------note----------- 695975 Cap-End (used before code date 00040600)

In this example:

• An engine with the CODE number 00304600, would use part number 695267
• An engine with the CODE number 00038651, would use part number 695975

(combinations of type and code dependant alternatives are often encounered, work out what you need in careful, logical steps)

Sump Gasket Thicknesses

Sump gaskets are listed with a choice of thicknesses (.005",.010",.015" etc.)to allow adjustment of excessive crankshaft end float.

The thickest option is the original size and is used in most cases. If however, there is excessive end play(in and out), then choose a gasket that will reduce it by the desired amount.

Piston and Ring Sizes

Most pistons and ring sets are available in oversizes. This is to accomodate cylinder rebore repair.

Only fit the size of rings to suit the size of piston.

An oversize piston will be marked as such(.020" etc.), generally on it's top face. It is worth checking for this if you require rings.
