Murray engine troubles

[Jim Thompson]

Well I talked to a repair guy and he told be basically what you just did. I knew the valves were in the cylinder, but figured the cylinder was replacable. NOPE. He said the cylinder is part of the block assembly.

I have found listings of replacement engines for this model, out of stock, but they list at over $1500????? All this for a $500 mower!!!

Google "small engine warehouse" and check their prices if you want to purchase new. I would check Craigslist and any local flea markets for a good used engine. There are quite a few around. There isn't anything special about the engines that Murray used and you should find any number of other engines compatible.:thumbsup:

That information is posted on nearly every gas pump.:laughing::laughing:

If you mean the $3.70 a gallon we pay here, I'd gladly pay that for an engine.

Well I checked with SEW and theirs were all over $1000. I have some ideas about trying to fix it. Not much to lose at this point if it doesn't work.

I'll try to see if I can find a machinist that can fill weld it where the seat goes, and machine it out to accept a new valve seat. if that fails or is cost prohibitive, I'll try a coule go for broke ideas I have. I will take pics to post, in cast it works. Maybe can help someone else down the road.

I don't know which engines you're looking at, but there were over 400 19.5 horse Intek I/C B&S engines for $510.

The arm and leg back then was over $185.00 to machine it and press in a seat.with no gurantee.I then offered one of the "wife's" legs..The price went up!! go figure.

I was looking at 20hp engines. I know there doesn't seem much difference from 19.5 to 20. but this engine is 750cc and all the 20hp engines around now are 600cc. Mine is rated for commercial use and is a very high torque motor. I do not really want to give up the torque, if possible.

I went back and did a search at SEW for a 19.5hp engine and got 3???? When I put in 20hp I get about 50, but over half are over $1000 so not sure what I'm doing wrong or different there.

Mark, $185 is cheap, to me. I'd pay $200-300 to get this fixed, that would be a lot better than $600 plus.

Well $185.00 might seem cheap now but several years ago it wasn't..and you need to remember that's just for the machining work. I would still need to buy a valve,seat,complete gasket set. put it together,etc.Then while waiting for a estimate from the machine shop I found a bunch of other "Gems" wrong with the mower.I found he musta had a deck spindle that he stripped the nut on.so he WELDED the blade on,etc. I would scrap the whole thing today if I had to do it over again.too

Well yours doesn't sound like mine, actually. I do believe this guy had no idea it was coming. He had just put new brakes, new battery, and new blades on this one, and gave me a set of new blades to go with it. I do not think he would have gone to all that trouble if he knew it was that close to breaking. Sorry yours was scrap.

I have a friend of the family that is a welder with lots of experience with aluminum, and I will machine it back down myself. I am going to try and just pull those two valves, and not disassemble the whole engine, if possible.

If this idea doesn't pan out, then I'll replace the engine. But this will lost me little or nothing, so I have to try. In the mean time I'm gonna start saving for this one. It's the one I really wanted, but couldn't afford, so I will have to wait I suppose. At $3000 it's pricey, but heavy duty.

Go back and find out who had an engine and was willing to give it to you... Pay whatever it takes for him to ship it to you... Sheesh!

Recheck your model #. A 27 hp engine is only a 44xxxx series and you listed yours as a 460777 which suggests that your engine is larger. As I recall, the first numbers indicate displacement in cu. in.
