Hi,

I am starting a project, maybe, rebuilding a 10 hp briggs & stratton engine, model 251417, type 0137-01. Everything seems to be in working order however the engine lacks compression. At the moment I am just researching what parts are available and the cost before I go ahead with this project. I am not having much success searching the net and finding a piston/ring kit for this model and type.

Any help / advice is much appreciated, this is my first engine rebuild project.

Thanks Sean

Hello Sean1972.

You might find this Briggs & Stratton pdf file useful for your search:
http://www.odref.com/briggsandstratton/model-25/251400-ms6370-0582.pdf

It lists part numbers common to engines 251400-251499. Piston sets come in standard size, as well as oversize. The illustration you want is on page 2, and the part numbers are listed on page 7.

You may be able to find aftermarket kits for your engine in addition to the original equipment Briggs & Stratton parts. You will use the part numbers listed in the pdf as a starting point for other sites to cross reference.

Double check that the model and type numbers you are using are correct. I can see how these are not helping, since using all the numbers you supplied fails to designate useful links.

By the way, the starting point I used for this search was:

I hope this helps,
HDNewf.

Thanks for all that information NDNewf, that has help me a lot. I really appreciate you going to the trouble of finding that for me. I should be able to get everything I need.

I have doubled checked and that model and type number is correct. I am right in thinking that I can use standard size piston rings? The cylinder wall is clean and not scored at all.

Thanks Sean

You're welcome Sean.

Normally on a engine you would want to measure the cylinder wall taper to determine whether an oversize bore is needed. One rule of thumb is to look at the ridge formed near the top of the cylinder by the uppermost travel of the rings. Just below this ridge will be the area of greatest cylinder wear.

If you were able to easily slide the piston and rings out of the cylinder, and there is no discernible ridge, then you can get by with a light hone and standard size parts.

You will need to hone the cylinder though. The cross-hatch pattern created is essential for seating the new rings. If you have a machine shop do this, then they can easily measure the bore taper and tell you what parts to buy after they make the cylinder right.
