The MODEL number is either 5 or 6 digits which may contain letters The TYPE number is 4 digits followed by an extension (Trim number) of 2 digits. Letters may be used in the extension The CODE number is the machine's serial number. The first 6 digits represent the date of manufacture YYMMDD (the example above was built 7th July 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 Sometimes, plastic covers or excess paint may obscure the details but they will be there. The only exception is if the main cowling or part holding the details has been previously replaced. In which case the details should have been retained from the old part.

When you click the Briggs and Stratton parts illustration link at the top of this page, the Briggs and Stratton manual search page will open at Step 1 Category. Scroll down a little and click the "Engine" logo.
The page will change to "Step 2 Equipment Type". From the drop down box,click the equipment that is closest to matching what your engine is fitted to. (This is not important as the selection does not alter the next page).
Click "Next Step"
At "Step 3 Model Number" enter your 6 digit Model number and 4 digit Type number with a dash between them. If your Model number has only 5 digits, place a zero at the front e.g. 9D902-0169 would be entered 09D902-0169.
Click "Search" and it should look for documents for your engine.
To the right and slightly below the entry for your "Illustrated Parts List" (english), you will see a small pdf logo. Click this to download the parts list pdf. Your parts list will be in your downloads for viewing or saving.

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:

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:

• 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

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

For example:

• An engine with the CODE number 00081800, would use part number 695267
• An engine with the CODE number 00032151, would use part number 695975

Crankcase 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 crankshaft end play(in and out), then choose a gasket that will reduce it by the desired amount.

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.
