Tecumseh 5 H.P. engine rebuild.

I just picked up another Ariens 5 HP snowblower and the whole engine has been taken apart. Don't ask me why but I would like to reassemble it. I need a book or website that shows the process. The engine is fine. Not sure why it was ever dismantled. Need a book.
It's a fairly new machine. Built in the last 10 years.

If it is an L-Head look in the sticky notes in this forum for a 4 stroke technician manual. It is a free down load. It may not have all you need but it is a very good reference and can get you started if your engine is in there.

I assume you have the engine model number and serial number?

It is usually stamped on the flywheel housing.

You might also want to check Clymer manuals if the info you need isn't found here.

Snow Removal Apparatus I own:
Ariens ST1530DLE, and good ole arm powered scrapper.
The 15 HP is a new Ducar engine sold
by Princess Auto in Canada.

Sorry Joe, just seen this post and had already replied to the other thread.
You will need a torque wrench to do the job correctly. Harbor freight has them on sale if you don't have one. If the connecting rod and piston were removed, a 1/4" drive torque wrench would be needed to fit in the tight space around the crankshaft.

Toro 8/24 (38080) 1989
Toro 721-QZR (38743) 2015 (Hemi Predator Power)

Experience is something you don't get until just after you need it.

Auto parts stores also loan torque wrenches. Not sure if they will have one small enough though. Pay the deposit and then get a refund when you return it.

Check out donyboy73 on youtube as well. Search through his videos as he has a lot of snowblower engine rebuilds. Some for carb rebuilt and some for head jobs and some for piston / rings and rod replacement.

Please direct all snow blower questions to the forums and not to me with PMs.

I hope you got it for free. Your not sure if it is an L-head or a OHV version. Just a pile of parts? well good luck. L-head has a finned head with no valves and the OHV has an actual head that has the valves in it. I would not even bother. There is a good reason why someone took the Tecumsapart. It most likely did not run.

Flathead. Tecumseh OHV engines only started at 9hp (and typically they were 12 and 13hp).

They're pretty simple to rebuild, and all that ever normally happened to them was catastrophic failure when the rod breaks, beyond that not much goes wrong with them.
