OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines B&S Model, Type & Code - Explained

Can anyone tell me exactly what the type number on B&S motors means? I have read quite a few different things about model, type and code numbers but the explanation of the "type" number is generally very generic and vague.Can you explain exactly what each part of the type number means? I feel sure that someone would have asked this before but I cannot find it.

I've found that the type number is important for parts ordering, The type number will appear when there is a variation Note in the model of engine part number needed.. the Note shows the different part number needed for that type number.

As you can see in the pic below.. also it shows how the date code matters too..

G'day folks,
As you're probably aware, the Model Number breaks down into info on the basics of the engine: capacity, design series, crankshaft orientation, carby type, PTO bearing type/auxiliary PTO's or reduction drive fitted/lube system, and starter type.

The Type Number - from one of the Briggs Service Manuals:
As far as I can find out, Briggs have never released a key to interpreting Type Numbers on their own. It's very much an 'internal code', known only to them.

It's also possible that the exact meaning of a Type Number is model-number dependent too; i.e. a given Type Number may denote different things on differing models.

But as SuperDooper says, it is essential for determining part design changeovers, in many cases.

Attached is information relating to the Model Type and Code for Briggs and Stratton Engines.
