Do you have a illustrated parts list for your generator? If not post make, model (UT number). Generators usually have engines made by someone else (Briggs and Stratton etc...). Post name on engine if possible.

ok,this is a Sumec; 9sums1931GAEM under the Homelite name from Home Depot. I searched and references to this bring up Firman followed by Chinese knockoffs. no luck finding anything to do with valve train let alone this secondary cover. I thought when I undid the outer cover the valve rockers and springs would be right there not this additional piece. once again, any help would be appreciated

Hi there hxm, This machine sounds a bit new for this forum but we can try. Do you have a Homelite model number for the whole unit? Have you tried that at Homelite's website? I personally have never heard of Sumec but you might get an ipl, illustrated parts list from Homelite on that one. It will show all the parts and how they go together, not in detail but usually enough to get you in the ball park. I searched for "Sumec 9sums1931GAEM parts list manual" and came up with a Coleman genset manual. There is an IPL there for 5.5 hp Sumec 175 engine. It looks like there is a second cover called a "breather assembly" over the valves held by the same bolts and likely stuck to a 2nd gasket. Take a look: www.arkansas-ope.com/SPE175.pdfParts for this version of the engine are listed at: www.arkansas-ope.com/ENGINE_SPE175.htmlI don't know if this is the correct engine but maybe this can get you started. These late model consumer goods marketed as Homelite are normally Chinese manufactured and relabled, may turn up with multiple names on them such as Coleman. I don't think Coleman makes anything anymore either. Keep us informed how you come out with this. Post up a pic, maybe someone else will have more info for you. Good luck. |

Dan you are definitely the man; that is exactly what I'm dealing with. the "breather assembly" is on there as though it were still bolted; I'll now be a little more aggressive with it and see what happens. the gen was marketed at clearance price and gave me years of service,it seems a same to junk it without at least trying to see if it could be repaired. thank you ever so much, I am in your debt, Mike.

No worries, is that the right engine?
If it is toast, maybe a different engine would fit. There are only a few different mounts between engines and gens of that class. Anyway, it looks like the parts might be available to fix it.
Good luck and Merry Christmas.

Anyway, it looks like the parts might be available to fix it. Good luck and Merry Christmas. Crap this is off topic, but not really, yes it is, oh well, If it needs deleted so be it. Sad to say, but most of these grey market engines are not repairable and are built to break in and break down on a schedule. It's really ingenious how they are able to make the parts wear down using inferior metal, the bolts break or fall off, and discontinue any replacement parts not that long after the engine is made. Yep, many of these engines will last several years or longer depending on use, but they are designed to die. In fact Toyota has been doing this very thing with the engines in many of their cars and SUVs (Google Toyota VVT-i and 1ZZFE engine oil problems, federal lawsuit.) since 1999 . They use an under size piston and compensate with a thicker ring, it breaks in easy and last 50,000-90,000 miles then after that the ring wear down they start using 1 quart of oil or more every 500-1000 miles. They know the warranty is well over after that many miles and know the owner will buy a new car and the old one will be sold at auction where it will end up at a used car lot and in the hands of a poor person buying a used car that will never have any legal recourse. The problem can't be corrected by new rings or a new engine because after the same amount of time the same problem will occur. Whats more even before they start using alot of oil, they start getting oil into the combustion chamber causing a carbon build up that clogs the PCV, destroys the catalytic converter and implores the CPU to make adjustments as to fuel, air, timing, and shifting. |

from what I found the 193cc should translate into 6.5 hp so this one is larger however the schematic is identical and my first goal is to merely open up the valve train and see what is causing the compression loss. since this gen owes me nothing a repair will need to be cost effective and parts availability will be a deciding factor. I do agree to the "planned obsolescence" where it is cheaper to discard and purchase another than to repair the original It pains me to throw out something that is not fully worn out but I have also been caught sinking good money after bad on units that I have a sentimental attachment to. sometimes you do need to know when to just walk away. as to a different motor all I have on hand currently is a 5.5hp Honda off a pressure washer with a cracked pump body. it could work thou it is a vertical orientation as opposed to a horizontal on the gen. I suppose if they would mate the gen could work vertically and it would cost nothing to try. I only count "out of pocket" expenses as my labour is free, a donation to reducing the amount of manufactured goods ending up at the "recycled steel" pile.

Using just any old engine on a generator I believe would cause issues. Most generator engines are governed to run at 3600 rpms to keep frequency at 60hz. Most other engines are not like this.

Undee brings up a good point, but many engines have a governor to hold them at 3600 rpm max. If that were true with a replacement, all that would have to be done would be to lock the governor wide open and fine tune for 60Hz. My VOM has a Hz scale so I never really thought much about it.
Lets hope the repair is cheap.
This is one of the major reasons I like the old stuff, it is repairable and it lives a long time. You do need a little help from time to time finding the right parts, that's why I hang around here. Friendly folks who agree with me. :{)

You cannot interchange a vertical and horizontal engine, well you can, but it wont work |

Easy there oologahan, its Christmas time and you gotta be nice. Well, you don't gotta but it would be nice.
He did say "I suppose if they would mate the gen could work vertically and it would cost nothing to try." It looks like he understands gravity and oil.
Remember too, we luv ya! (in spite of the crap that Home Depot sells.)
