Small Engine Troubleshooting Problems? Ask a Mechanic Now.
I'm not sure what drive shaft you're referring to. Can you be more specific?
If you're talking about a snap ring like the one below, then all you need are snap-ring pliers. These are available at any auto parts, hardware or tool store, ie: Sears. They run about $7-10 for cheap ones. A decent one with multiple tips that will hold up will run about $40. Let me know if this isn't what you're talking about. Thanks, PK.
There are only two pulleys on the engine crankshaft, and one of them is part of the electric clutch. There is no driveshaft which is why I asked for clarification.
There is a motion belt pulley, which drives the belt which drives the transaxle. There is the PTO clutch with the pulley for the deck drive.
There is no clip that holds the clutch or the motion drive pulley onto the driveshaft. There is one bolt that goes into the crankshaft through the center of the PTO clutch. Once you remove this bolt, the clutch comes off.
The motion pulley is not attached by anything else although it is very common for the key to rust to the pulley and crankshaft locking the pulley in place. There are a few options for when this happens and it happens on about 99% of all MTD drive and combination pulleys. This may be what they are talking about. There is a special tool for pulling pulleys off, but it's not necessary and we rarely use it in my shop.
I've done quite literally hundreds, if not thousands, of MTD belts. If you can detail just where this clip is supposed to be, I can help you.
You don't have to Accept until we get this fixed.
I would say take some Kroil and PB Blaster. If it's the upper pulley, the one that drives the motion belt, and it's rusted on, the best way to remove it is by spraying above it every ten or fifteen minutes until it comes loose. It can take a day or more worth of spraying.
Usually the reason people want to remove this pulley is because the belt guard is three metal tabs that are a part of the frame and you can't get a new belt between the tabs and the pulley. The way many shops put these belts on, even if they won't admit it, is to not bother with the pulley and instead just bend the tabs back. It takes a long prybar, I use one that's about 3 feet long and one that's about 1 foot long, and a bit of contortion. The other option is to remove the four bolts that hold the engine to the frame and slide the engine back. Moving the engine is actually pretty easy and we do this fairly often as well.
If it's something different he's trying to fix, let me know and we'll go from there. We see a lot of MTD's come in where people are unable to replace the drive belt. Thanks, PK.
Thanks and let me know if you run into any trouble.
