Model #917275400 Craftsman lawn, tractor

Question and Answers

Q:

I have a Sears tractor, Model #917275400. The engine # 31H777-0297-E1. The piston rods are blown.

A:

Thank you for your question.

I am sorry you are having a problem with the engine. The engine you are wanting to install will mount to the tractor but you will have to purchase a new muffler and rig up a new throttle cable. The original cable will not reach the new engines connection. The wiring will have to be spliced also. If you do not feel confident in your mechanical ability to complete the engine swap, I recommend staying with direct replacement engine.

I hope this helpful.

I have checked and can confirm that the single cylinder has a 1 inch x 3 5/32 inch. I have looked for the dimensions for the twin but could not find them posted. I recommend measuring the shaft on the twin before attempting the swap. If the shaft is not the same, you could have a hard time finding the correct pulleys.

A:

The starters on these two engines are not interchangeable. I strongly recommend replacing the defective engine with the recommended replacement. The replacement engine will fit your tractor with out modifying. The engine can be ordered from the link below.

Q:

I have a lawn mower #917275400 and am trying to change the oil. I've misplaced the drain tube. Can you tell me the diameter on that so I can get another one?

A:

Thank you for your question.

I am sorry you are having a problem with finding the hose. The hose should be a 3/8 I.D. You should be able to pick this up at your local hardware store. I recommend finding a thin wall hose. The reason is it will be easier to slip on and take off.

I hope this is helpful. Please let me know if you need further instructions.

Thank you for using Manage My Life!
