my grandpa said out on the farm if an engine blew they would find all the peices of the block and epoxy it all back together and it would be good. is this possible? or is he just pulling my leg?
destroyed a connecting rod in my TEC H70 after pulling approx. 5300 rpms on my kart, fortunately it didn't go through the crankcase...going with an TEC HM100 with a billet rod this time around..
If you look, you'll see metal transfer on the crank. The only way you get that is heat, And the only way you get that heat is low oil. When an engine fails from over reving 90% of the time it will bust the rod High(close to the piston). This failure is from low oil.
@donyboy73, were there a bad run of engines that Tecumseh put out? I have a 2006 Ariens 824 snowblower and I do take care of it and dont abuse it, however I'm afraid this will happen to me. I also use Mobil-1 synthetic oil as well. How many of these bad connecting rod issues have you seen?
im rebuilding a 6 and a half hp tecumseh and im wondering how much a new piston would cost. the cylinder isnt bad i bored it out. the piston that was in it was cracked down the side.
if i were to repair a tecumseh engine muffler that was built in 1979 and hasent been changed in that ammount of time what would be the odds that the bolts break in the engine
I love these old tear down videos. Seeing the inner workings of an engine is kinda neat. Makes me wish I knew more about small engine repair and mechanics in general. Eh?
I've worked on tones of these eninges and I've only had a couple that had thrown rods. The biggest problem that I run into with these engines is the bowl gaskets shrink and allow fuel to rust the bowl and the carb and then you get that nice varnish around the seem were the bowl and carb meet up. But then again most people leave there old ass fuel in there and let it go bad.
i can keep my briggs redlined for hours and it was made for a tiller and i rigged it up on my gokart and it works great. tecumseh used cheaper metals in their products which evidentually lead to the company`s demise.in simpler terms they cheap out to the extreme and people started to notice their engines throwing rods.
My neighbor's old Craftsman riding mower with 8hp Tecumseh threw a rod the other day while he was cutting his yard. The broken piece of the connecting rod landed on his roof, and there's now a ~3" diameter hole in the side of the block!
Good Autopsy!. I've done a few Briggs IC and even a Honda GX340 and the story is always the same. over-revved, big end or counter balance lets go and BOOM!.
i have a techusume 10 hp engine for lawnmower, i was told they do not make that motor any more and i cant get a piston replacement,can i use a biggs piston n rod for it if so can u give me parts number so i can buy the piston and rod and rings for my engine thanks.
I recently used a short block for the exact same engine that is in this video. I made sure I replaced everything exactly the way it was installed on the blown engine. I went to start it and it ran for about 15 seconds and now won't run at all. It has compression, it has spark, and the spark plug is wet. Does anybody have an idea on why it will no longer run. Thanks
How modern of a Tecumseh is this? Mine is like 30 years old and I can see a few differences. Are the old ones better then the newer ones or are the all this bad?
Tecumseh is known to throw rods... I've heard the carbs suck, but the emission ones in particular.
I like Briggs engines, I've seen an old one on a 1970s snowthrower and it seems to run a little off, never rebuilt the carb on it and it had the original plug up until last year (used very little).
The old tecumseh engines are good, the Chinese engines, well, the China companies can't make cat food right. Do you think they can make a good engine?
I have a question, do you get a lot of tech. engines with blown rods?
also do you have a preferred engine, Briggs, kohler, tech, Honda?
well i like briggs and never hardly liked tech. its not that i don't know how to work on them, but some of them can be a pain, and every tech. i manage to get its, junk carb or thrown rod, everyone of the ones i got were bad, idk if its luck of draw or what. but good videos and repairs!!
@motorhead45102 i prefer briggs on lawnmowers, tecumseh on snowblowers. but now all the blowers come with briggs which are good now on blowers and chinese engines. i wasn't too crazy of the old briggs on snowblowers.
@motorhead45102 i prefer a Briggs over Tecumseh but have loved the Kohler engine i just got with my new mower, on my minibikes i prefer B&S easier starting but it really dosent matter the brand just that u keep it maintaned with regular oil changes and so on
@motorhead45102 exactually the only reason i would prefer a briggs is because they seem to start up a little easier in a small engine with just a pull rope, the less pulls the better! LOL
Block can be repaired, but I heard that a new conrod is so expensive that repair is not worth it even though all other parts could be reusable. Is it really so?
Crankshaft propably doesn't get so much damage, as the rod is aluminum, and the big end melts to crank on these cases. Surface could be unharmed on crank, if aluminum residues were carefully removed?
i have just parted out a 1990 tecumseh 8hp genset engine. did the same thing. the conrod broke the cylinder bore, the whole piece behind the starter and twisted on side of the piston skirt all up. the engine had been perfect. no scoring in the bore or bearings.
holy crap that's a big hole in the block!!!!!
