13.5 hp Briggs oil leak / cracked block
Comments (10)If, after tearing it down, you do not SEE a crack......you might want to use a method I learned from an old motorcycle mechanic years ago. Clean the surfaces of the block just as clean as you can get them using a mineral spirits type solvent. After cleaning with the mineral spirits, spray the surfaces of the block with aerosol carb cleaner or aerosol brake parts cleaner (the idea is to remove the solvent from the surface of the block). Allow the block to dry completely. Next, spray the entire area where you suspect a crack might exist with a "talcum powder based" aerosol deodorant. You want to get a good coat of talcum powder stuck onto the surface of the block. Next, use a heat gun, hair dryer, or a heat lamp to warm the block. What will occur (if a crack exists) is the solvent and old oil will be expelled anong the crack as the block warms and the crack will be revealed as a dark line against the white backdrop of the talcum powder....See MoreBriggs and Stratton 24 hp ELS Engine
Comments (79)Hi all, I'm not mechanically inclined, so if you could give me some thoughts on what has happened I would appreciate it much. I have a Craftsman Pro Lawn Tractor, it has the B&S 24 hp ELS V-Twin with a 24" cut, that I just use here at home,(2 Acres) I've had it about 2 maybe 2.5 years and it is out of warranty. I was riding it from the garage to the yard (blades were not engaged yet) when a very loud pop happened and it died. After that, when I tried to restart it, the motor just turns but it will not start as if something in the engine broke..... I DO think this is MY fault (and I'm embarrassed to say this), but I think I was low on oil - could you give me a suggestion as to what may have broke, due to my ignorance, so I can at least have some idea of what to tell someone it may need when I try to find someone to give me an estimate to repair it? BTW, I live in a rural area and do not have any authorized B&S centers within approx. 80 miles of me (Sears store is about 58 mile away too). One last thing, I have always put new oil and filter, and air filter on it each year, and last year I put a new spark plug on it in addition to the other maintenance - I have tried to keep it running well, but this year I just made a MAJOR/stupid mistake that is gonna cost me......... Thanks for any suggestions guys (and ladies) :-)...See MoreOil leak -- Briggs and Stratton 24 hp ELS725 Engine
Comments (10)Hello, semi-purist here. If you are not reasonably experienced in "torquing" fasteners, or would call yourself a novice, I suggest you obtain a torque wrench. Rusty KNOWS what tight feels like, but he sometimes forgets that it is a talent that comes from years of experience (Big grin :^). Even if you "have the knack", it can vary from day to day, or even with the time of day (you don't want to hear that story). I also suggest that you go ahead and buy the service manual from Briggs. It is a small investment when factored against the prospect of always taking the machine to a pro shop. Not that I have anything against pro shops, I just always advise folks who think they might want to get into "the heavy stuff", to have all the "tools", including the OEM service manual. Also, be sure to follow another of my standard suggestions (for all disassembly procedures of any/all components), TAKE LOTS OF PHOTOS of your disassembling in "step by step" fashion. Shoot from different angles so you capture every aspect of how items are fastened, routed, oriented, etc. Using a digital camera makes this a painless and cheap "diary" of the whole deal. Rusty's plan above will work. I'll add that any pulleys on the PTO end of crankshaft have to be removed before the sump can be removed. I have provided a link to the Briggs online IPL below. You can download a copy to your computer, it's PDF. The gasket for sump is item 12, Briggs part # 697227. You should also replace the crankshaft seal, item 20, Briggs # 690947. While the sump is removed from the crankcase, clean all rust from the exposed part of the crankshaft (everything that is outside of the seal contact point). Inspect this area of the crank for burrs or any other defect that might cut the new seal. There is also another thread currently active wherein another member is doing a similar gasket replacement. I'll post a link to that one. Just don't be deterred by the "thrashing" we gave happy123, he sort of set the stage for it and I'm not so sure he wasn't yanking our collective chains (now that I look back, I wonder). Here is a link that might be useful: Briggs IPL for 446677...See MoreOil leaking from my briggs engine
Comments (1)Sounds like a connecting rod may have broken and holed the block. Pull the spark plugs one at a time and turn the motor by hand. If the engine turns freely with one installed, you have a serious problem....See Morevinnie_s
