snowblower starter

I have an older model snowblower from Canadian Tire.After 20 years,the electric starter just makes a whirring sound.
The starter ia Tecumseh Products #33329C serial#18114.
I have removed it and checked the gears on the snowblower and starter.Both are a little rusty but ok.
The starter operation seems ok.The shaft extends with the gear when button is pushed but i suspect that the gear does not engage in the snowblower for whatever reason.I understand that this portion is called the "bendix" and can be replaced.Were can i get the necessary parts and also a diagram so i can know what steps to take in taking it apart.The tecumseh site does not even list electric starters as one of their products.
Any help appreciated and thanx in advance

 

The starter is just doing the whirring sound and the engine is not turning over, but the bendix drive is moving up the shaft and both the bendix gear and the teeth on the engine flywheel look OK?

A common cause of that sort of thing in a battery driven starter is low voltage, but I assume this is one of those that uses an AC outlet for power?

I doubt if replacing the bendix will do anything, unless it shows some damage. Check the mounting of the starter to make sure it's properly aligned and the mounting bolt are snug. Before you reinstall it lube the starter shaft - sometimes that makes a lot of difference.

If you still have a problem, you may start looking for another starter on EBAY. I believe have seen that starter for over $200.00 new.

 

Yes it is ac powered.One of the reasons i think it is the bendix or at least the gear on the starter is that i can move that gear in either direction.I would have tought that the gear would only catch in one direction.Also if i extend the shaft,i beleive the gear should then lock in one direction but it does not.

It sounds like the sprag or overrun clutch,which lets the bendix"freewheel" when the engine starts, in the bendix is worn out. So you still need a new bendix or starter.

That is correct. The gear only catches in one direction. If yours is free both ways I'd say you were correct in needing another bendix.

 

Here is a breakdown of the starter. It has been superceded to 33329E. Once you identify the parts needed throw the PN's into Google or Ebay to find best prices.
