I have a not running briggs and stratton 450e in which I need a new rocker arm stud I cannot for the life of me find the right part any help. The serial number is missing, I bought this second hand. Thanks in advance ask me any questions you have.
 
The engine model number maybe etched into the side of the engine block next to the muffler. That number will get you to a parts diagram to see what parts are available.
 
Clean and wipe the engine block down on the flat sides. There are Lazer etched numbers that will tell you what you have for an engine. Usually Jacks small engine or e-replacement will have what you are looking for.

Why the rocker arm stud? Did it break?

Hi Go Cart Builder,

You're supposed to only tighten bolts 1/4 turn before they break. LOL

Anyone who has worked on this stuff expects things to break from time to time. Better that it broke now than when the engine was running at 3600 RPM.

The newer they are the cheaper they make them.... Minimize materials and maximize profits is the name of the game. The end user is stuck with the results.

I think StarTech provided the part number you need.

Manufacture got it down to a science. A piece a little thin made of a cheaper material. We talking about a fraction cent if they can save it over a long it can become a large amount. This is why we see so much plastics in use. Plastics are easier to mold than stamping a sheet of metal.

It is like the Briggs 793880 camshaft which the PN has been superseded with no improvement in the part reliability but they make a lot of money selling replacement parts. It seems that they build in a failure rate on these.

Or the replacement of a gasket with RTV. Gaskets require a die which must be replaced every so often and the right materials where RTV doesn't. And they don't care how much trouble it is to repair something either. I spend more time disassembling and reassembling than actual repair time for the real problem.

I mean they got it down to number of days a part will last and their warranties are right on the edge of failure. I have seen things to fail one day out of warranty. IF they could make a part out of thin air they would try.

Durability comes at a higher price.
