Q:

my mower will not cut even do i need deck wheels? 917256810

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you're having with the uneven cut. I know how frustrating that is.

Deck wheels help prevent lawn scalping and wouldn't necessarily help with the even cut. I suspect your deck is out of level and needs to be adjusted. The side to side and front to back adjustments are covered in the owner's manual on page 21. 

I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.

Q:

exuast valve not opening as maybe tappet valve stuck so how do I take apart unit and replace tappet valves and or maybe cam? 917256810 Craftsman Tractor

A:

Thank you for your question and I understand your concern. 

The first step is to remove the valve cover and inspect the rocker arm. Remove the spark plug wire and spark plug and spin the engine over to see if the push rod and rocker arm is moving up and down. If the exhaust valve push rod is not moving any at all, the engine will likely need to be taken apart to inspect the push rods, tappet and cam. The rocker arm, cam and tappet is likely ok but more likely the rocker arm clearence will need to be adjusted. You won't know until you remove the valve cover.

Turn flywheel until piston is at TOP DEAD CENTER at end of compression stroke and beginning of power stroke.

Adjust valves turning lock nut until valve clearance is:
.004−.008” (intake & exhaust)
Rotate crankshaft at least two (2) revolutions and recheck valve clearances. Readjust, if required. Here is link to a service manual that may be helpful. If you do not feel confident in diagnosing and repairing your engine, I recommend taking the mower in for repair.

Q:

My Craftsman riding mower's belt broke on the 42" deck. I purchased a new one at Sears, but unsure how to put it on. Any advice,please?

A:

I hate installing new belts on anything, so I understand. A suggestion I have is to check the owner's manual for help and possibly diagrams. I attached the link to your model below. I also found a video on how to install a belt on a lawn tractor. This may help while you wait for the expert answer. Hope this helps!

A:

I have provided you with the instructions for removing the deck and replacing the belt below. It is not necessary to completely remove the mowing deck but it makes it easier to clean the under side of the deck. Make sure to park the tractor on a level surface and set the parking brake before servicing the mower. If you need further assistance, please feel free to submit more details.
