Getting Started

First, be sure to check the owner’s manual provided with your lawn mower. While these general tips from Hometown Outdoor Power can be applied to most lawn mowers, the owner’s manual may include more detailed, model-specific instructions on how to replace the engine.

Once you have reviewed the owner’s manual, start the engine replacement process by tipping your lawn mower on its side. Wedge a block of wood between the blade and the mower deck, and use a wrench to remove the bolt securing the mowing blade to the mower engine crankshaft. Unscrew and remove the mowing blade, then lay the mower down flat.

Removing the Engine

To remove the old engine from your lawn mower, start by following the throttle lever to the throttle linkage on the side of the engine. Use a screwdriver to remove the throttle wire, then unscrew the bolts securing the engine to the mower frame. Use a wrench on the bolt head on top and on the nut under the mower deck. Repeat these steps to remove all the bolts, then carefully remove the old engine from the mower deck and set it aside.

Installing the New Engine

Next, place your new lawn mower engine where the old one was, then replace and tighten all the bolts and nuts until the new engine is secured to the frame. Reattach the throttle linkage, then put the mower on its side again. Screw the mowing blade back into the base of the crankshaft, then use your block of wood as a wedge as you tighten the bolts.

Testing the New Engine

With your mower lying flat again, give your new engine a test run. Fill the oil and fuel tanks, then turn on the engine and watch out for any unusual sounds or vibrations. If the engine seems to be installed properly, take it for a quick spin around your lawn to test its performance.
