I have an HRX217HXA that the engine locked up on in the middle of the front yard. I pulled the valve cover and found a badly bent intake valve. I bought the mower used and it has burned oil since I bought it.

Anyhow, I’m not interested in rebuilding the engine so I’m looking to replace the one I have. The current engine is a GCV190 S/N GJAAA-1382151-MY2. I cannot find a “PTO” shaft size in any documentation that matches the dimensions of the one I have. Does anyone know what exact GCV190 part number I need for my mower?

Thanks in advance,
Mike

My mower model is not listed on that website. Thank you for the suggestion.

You have to remember you have a BBC unit. The BBC uses a different flywheel. It is heavier because it needs the extra balance when you have the Blade in Brake mode.
If you cannot find one that is most likely the answer.
If you get one just put the old flywheel on the new engine as long as the shaft specs are the same. I have seen this engine advertised before on ebay.

I think GSV190-LAN1L fit your model ,this one is better than GCV 190 and have same shaft 7/8-3 3/16 keyed .Check your shaft to make sure
