Rebuilding a 9 hp Briggs

Recommended Posts

lboy1971
In advance, thanks to anyone who can help me. I am only 14 and have not worked on an engine before, nor do I intend to. I was just wondering, how much it would cost to have a mechanic rebuild a motor this size? I am going to overhaul it with a new connecting rod, rings, piston, and bearings. It may need a new crank and to be bored out as well. A rough estimate for all this would be greatly appriciated. Please e-mail me at my new address bradleybecker1@hotmail.com. Thank-you again.

Hi Brad, I don't know that much about Briggs, but don't be afraid to dig in and do it yourself. There's a lot of guys on this site that can help you thru the process. There'll be some things you have to have done by someone else, like machining, but you'll enjoy the process more if you do as much as you can yourself. As long as you take your time and use a little common sense you can't hurt anything. Sam, Les, Kent, Herb and any of you guys with Briggs motors, can you help this young man out? He's the future of our site. Paul

If you're not going to do the work, don't take the engine apart. Mechanics usually charge more to put a "basket case" back together. Check with your high school votech department. The teacher may be looking for a class project, and you can save a few bucks. You may want to consider Paul's suggestion and tackle the job yourself.

Brad, cost of parts I can't help you with but a resent post was talkin 35 bucks to bore one. Would like to encourage you, if you have a place to spread it out in order, to get a briggs manual and do the work yourself. the feeling you'll get when you fire it up will stay with you a long time even if you never grease monkey again. Small engines are a good place to start. thier just nuts, bolts and some pieces of iron...GO FOR IT Young Man...MPH

I have never rebuilt one either, but I want to next year some time, if for nothing else to see what its all about. Have to get a few more tools though. As with anything new, a person has to read some books on the subject ask some questions to people that have been there done that, lose the intimidation over it all and simply do it. Like Dutch suggested, a High School Shop class is a good place to start.

I'm 52 years old, but I' like Brad and intimidated by all the parts I'll find inside. But I'm going to try rebuilding 2 Kohler engines this winter. I may be seeking advice from club members also.

Here in Wisconsin, to bore out an old case iron B&S or Kohler with new piston, grind valves, grind crank, etc. will run from $350 to $500 at a motor shop. Good Luck! Mike S.

Hey BradB, If I'm not mistaken, BradW is a little closer to you in age than most of us. I'd connect up with him, if I were you. Not that age matters on this site, but you can relate. Paul

Thank you all for your encouragement! I am really going to try my best to maybe put the rod, piston, and rings in myself, but the regrinding will be up to the machinist. We own many AC tractors and about as far as I go on working on them is changing the oil and cleaning the plugs. This may be a different story, though. I might just tackle some of this myself. I just have to put this B-10 back together. It was the first one I owned and although we have a 917 and a 720, it is still my favorite one. Funny how we have all these new equipment now a days, yet we still call upon the old ones to do the tough jobs!

Brad, As Sam suggested, get a book and read it before you begin. Mark all parts for front, back, top, bottom, left, right, as you disassemble. Use the proper tools, and don't take shortcuts. Select a good machine shop and don't tell them what the engine needs, let them tell you. And, most important, ask if you have questions. Good Luck.........

BradW,thank-you for the reply. I was wondering how far I dare go boring out the piston and the chamber in this motor? Mine has been bored out to .020 of an inch already. Could I go to .030 or .040 of an inch more? And again, where would parts be cheapest? Should I go through Simplicity or like a local Briggs repair shop dealer? . It ran strong the first three years I owned it, then after this spring it really went down-hill fast. I would like to think this is only the second time this motor has been opened up, but that I do not know. Any info and the above is greatly appriciated BradW. Jordan, thanks for your reply also. My dad, my brother, and I own about 14 tractors. We have WC's, UC's, WD's, 3 WD-45's,a CA, a D-15, a D-17 Series 4, a D-19, and a 190 XT series three. We also are restoring the ultimate AC,a D-21 series 2 for one of our neighbor friends. As far as garden tractors go, we have my original 1963 B-10 and my brother has a almost mint one of the same year. We have a parts Big-Ten, a 1966 B-10, a 720, and a 1982 917 also. My brother had his 1950 WD on the cover of Antique Power magazine in Nov./Dec. 1998. If you see it, I also have a WD-45 with a wide front identical to his. Hope you all had a very, Merry Christmas!! BradB

BradB, I am 15. Ain't rebuilt one yet so I can't help you. What AC tractors do you have? We have an 8030, D-17, B-110, B-112, B-12, + a 1967 Simplicity Yeoman in Perfect condition and a 1999 Simplicity Landlord. Jordan
