Techumseh lv195xa on Toro Recycler Self Propelled. Has bad

Customer Question

Techumseh lv195xa on Toro Recycler Self Propelled. Has bad vibration, calms down considerably when blade is engaged. Flywheel sheer pin is not damaged.Did some measuring and blade and crank shaft seem not to be bent, measured blade at 4 or 5 points around deck (measured both ends of blade at each point). Have not used a dial indicator on end of crank but vibration is excessive enough that it seems it would be visible.

Hello, and thank you for choosing Just Answer. My name is***** will be happy to assist you. Have you checked your engine mounting bolts, to see if they are all tight?

What about your blade adapter? Have you checked to see if it have a crack in it. It could be a hairline crack?

Customer: replied 1 year ago.
I haven't but wouldn't the vibration be present with or without blade engaged?
Customer: replied 1 year ago.
Vibration practically diapered with blade engaged
Expert:  Donald replied 1 year ago.

Thanks for your reply.

Do you remember ever striking a solid object with your blade, at some point??

Customer: replied 1 year ago.
Not at all.
Expert:  Donald replied 1 year ago.

If all of your mounting bolts are good and tight, and you experience vibrations, when your blade is not engaged, this leads me to believe your crankshaft could be slightly bent.

Expert:  Donald replied 1 year ago.

Can you get the model numbers from your frame for me?

Expert:  Donald replied 1 year ago.

I would like to see what all is attached to your crankshaft ...

Customer: replied 1 year ago.
I can't right now but the drive pulley, blade mount and blade are all that's on it.
Expert:  Donald replied 1 year ago.

No problem. I wonder if there is any play in your drive pulley?

Customer: replied 1 year ago.
Blade is tight.
Expert:  Donald replied 1 year ago.

I have another suggestion ...

Customer: replied 1 year ago.
I could check that but its hard to imagine that pulley causing that much vibration?
Customer: replied 1 year ago.
Is there internal dampers as in larger engines?
Expert:  Donald replied 1 year ago.

Checking the pulley was just another thought. At the top and bottom of your engine, where your crankshaft comes out, check for excessive play in this area.

Expert:  Donald replied 1 year ago.

Your engine is not equipped with an internal synchro- balancer ...
