The Step-by-step Process of How to Tighten Drive Belt on Craftsman Riding Lawn Mower
When the drive belt has been loosened, you will have to tighten it properly through the correct step-by-step path, and the processes for that are:
Step-1: Place Selecting and Collecting Necessary Tools
Selection of the place where you will tighten your craftsman lawnmower’s drive belt is much important for the whole procedure. The workplace should be even, and there shouldn’t remain any ups and downs. An even surface will make the drive belt-tightening process a whole lot easier by eliminating instability.
You will need some tools to complete the entire process, and the tools are:
- Screwdriver – To unscrew the screws from different joints.
- Wrench – For unmounting the nuts and bolts from different parts.
- Lifting Jack – This tool will help to lift up the mower-body.
- Cleaning Brush – It will help to wipe the dry-dirt from the deck.
- Gloves & Sunglass – For the safety of your eyes and hands.
- Towel and clean cloth – For clearing the dirt from the mower-body.
- A mat– To keep the mower body away from the dirty surface.
You will have to collect all these tools before the start of the proceedings.
Step-2: Preparing the Lawn Mower
At first, you will need to put a mat over the surface area you selected. Then place the lawnmower body properly on there, and make sure it is stable. After placing the machine, activate the parking brake, disconnect the spark plug wire, and turn off the ignition switch and the craftsman lawnmower engine.
Put the gloves on your hands and the sunglasses on your eyes. Another necessary thing you will need to do is emptying the gas tank of the mower. Keep a clean cloth beside you to put the needed materials there and tell one or two persons to stay ready for the necessary times.
Step-3: Detaching the Blade and the Deck
The next thing you will have to do is remove the blade and the steel deck from the lawnmower body. Lift-up the mower body by using the lifting jack you kept beside. You can even turn the mower upside down by taking the help of your assistants. With a wrench, turn the mounting bolts of the blade anticlockwise to loosen them.
As you will loosen the mount bolts, the blade will tend to fall on the ground. So, while you unmount, tell someone to hold the blade and put that down safely when the unmounting process completes. In the same way, you will have to unmount the bolts and screws off the deck with a screwdriver and a wrench to disconnect it from the mower body.
Step-4: Cleaning the Deck and the Blade
As you will detach the deck and the blade, you will need to clean them. At first, wipe as much dirt as possible from the steel blade and the deck with the cleaning brush. Then put the steel blade into the soapy water and scrub it using a scrubber.
The deck should also be scrubbed with soapy water. After rinsing, let the blade and deck dry a bit, and then wipe them both with a clean towel.
Step-5: Tightening the Drive Belt
Locate the transaxle pulley first, and you will see the drive belt there. Detach the screws of the belt to remove it from there, and wipe the dirt with a piece of cloth or a towel. Make sure no dirt is causing the belt’s loosening or making it jammed in the pulley later.
Then you will have to loop the belt back in its position in the transaxle pulley correctly. Tighten all the mount bolts and screws with the wrench and the screwdriver. Check it several times to make sure the drive belt is tightened enough. Install the flywheel screencap along with the washer and tighten the bolt of the screencap.
Guide the drive belt through the rest of the pulleys carefully, and make sure it is in the accurate route. Then you will have to place the crankshaft pulley, and all your tightening work will be completed.
Step-6: Re-assembling the Parts
Once the tightening work will be done, you will have to put the mower parts back together. Install the deck and the blade, and make sure the mount bolts and screws are tightened firmly.
Then drop down the lifting jack if you used it, or if you turned the mower body upside down, put it back in its actual standing form. Deactivate the parking brake, connect the spark plug wire, turn on the ignition switch and the engine, and the mower will be all set to run again with a tightened drive belt.
