Sheared a second flywheel key on my Tecumseh HS50
Original Message   Jan 25, 2006 3:28 pm
I'm continuing my quest in a new thread now that I have a more specific question. Old thread is http://www.abbysguide.com/ope/discussions/19249-0-1.html

I got a new flywheel key as the old turned out to be broken. The new one broke after about three pulls and one ignition...

The new key looks like a dud though. The sheared surface looks dimpled as if the metal had bubbles in it. The old one looked solid and the sheared surface is smooth.

Could I have been so unlucky that I got a bad new key or is a second broken key a sign on some other problem? If I remove the spark plug and turn the flywheel, it seems to run smooth.

Success!

I got me a decent torque wrench and cleaned the surfaces properly before assembling this time. No problems at all and the engine started on the second pull :)

Thanks

OFR,

What was the setting on the torque wrench ?

I set it to 62Nm/46ft. lbs. as the repair manual I have said.

Now I'll make some final ajdustments on the carburetor, change the oil and get a new belt for the blower fan and all should be in top shape. Feels good but I'm sure we will get *no* more snow this season.
