Q:

How much will it cost me to have a new engine installed in my Tractor (20 H.P.) ?

A:

Thank you for your question.

I am sorry you are having a problem with the tractor. I have looked up the model number you have submitted. The replacement engine for the tractor is part number 331877-3036-G5 and can be ordered from our parts website. 331877-3036-G5. The cost of the engine is $ 768.15. I am sorry I cannot give you the cost for labor because the technician would have to give an estimate on that. You can call 1-800-469-4663 to schedule service.

Please let me know if you need further assistance.

Thank you for using Manage my life.

Thank you for your question.  I am sorry you are having problems with your Craftsman tractor model 917.289213. I posted an image below that shows how to adjust the rockers. Click on the image to enlarge it. The rockers should be set to between 0.003 – 0.005.    If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a  Sears technician.  Here is a link for the website:  Sears Home Services . Thank you for using Manage my life.

Q:

oriface color chart for Kenmore 79072903010

A:

That conversion should be completed by a qualified installer.

I added the instruction pages for that conversion kit 316542416 in the images below in case you need them. That 4th page shows the instructions for converting the range back to natural gas. Here is a configuration for those orifices:

  • Right Front -- 210
  • Right Rear -- 107
  • Center -- 146
  • Left Front -- 146
  • Left Rear -- 167

This should help you complete that conversion. If you need more assistance, let us know.
