The chainsaw industry would have been very far behind without the inventions of McCulloch. Decades ago, McCulloch introduced a single-man chainsaw and changed the fate of North American Woodworking. Husqvarna acquired McCulloch in 2008, and since then, it has been a separate business division in the Husqvarna group. McCulloch chainsaws and other tools are still best, durable, reliable, and do their work exceptionally well. However, you may need to take apart your McCulloch chainsaw for several reasons, the most common being repairs or general services. Whatever the reasons, maybe, this article will help you disassemble your McCulloch chainsaw.
How to take apart a McCulloch Chainsaw
Time Required: 2-3 Hours
Difficulty Level: Moderate to Hard
Things Needed
- Tool kit
- Cleaning brush
- Deep plastic tray for holding screws
- Piece of cloth for spreading on the work table
- WD-40
Procedure
Please note that this article will cover the taking apart of Eager Beaver model 2.0. It is one of the most famous models of the brand and is still widely used. We suggest that you read the entire guide before starting the work. It is best to keep a cell phone with you and take pictures of everything before taking them apart so you can reassemble them easily by looking at the pictures. It would help if you placed the saw on a waist-height table, so you don’t have to bend over while working on it. Spread a piece of cloth on the table and place all the removed parts on it. Arrange them in order, so you know which goes where. Make sure you remove the chain before getting to work. If you feel like you cannot continue to work, call a professional and ask them to take care of the process.
Part 1: Taking off the Fragile Parts
The first thing to do is to remove the fragile parts from the chainsaw. For this purpose, you will need a flat screwdriver. Remove all the covers from the chainsaw. It includes the cylinder shield or any other plastic covers installed to protect the inner parts. Remove the filter and then remove the starter by opening the three screws on it. When the starter has been removed, lock the starting cord on one of the teeth of the starter’s cover. Take a clipper and cut the starting cord from the end near the starting handle. You must cut it above the handle and not from any part between the handle and starting assembly. Take out the starting cord, put it back on the handle, and make a small knot on the handle’s upper side, so the entire structure stays together, and you can easily install it back. Now you have to remove the cover on the other handle. Check the size of the nuts and grab a screwdriver according to its size. Open the cover and place it on the side. The bar will automatically come off now. Now you will see the clutch, muffler, and the point where the oil comes out to lubricate the chain and the guide bar. At this point, don’t try to remove the second handle as it is not designed to come off in this way. Once the cover has been removed, it will come out by twisting it backward. Remove the front cover with the help of the appropriate opening tool and remove the cover. Now you can remove the handle by revolving it backward and sliding it out.
Part 2: Fuel Tank Removal
By now, the fuel tank will be visible, and the next step is to remove it. To remove it, you need to pull it straight out. You may need to shake the tank a bit to take out the holding knob from the engine body. You may need a screwdriver to pull the fuel tank out. In case it is stuck, a little WD-40 will help. If the tank is dirty and has grease on it, you must clean it thoroughly before putting it back.
Part 3: Engine Removal
Before removing the engine, wipe off the dust from its surface to not make your hands and tools dirty. The next step is to remove the throttle pin. Hold it with a nose plier and then put a small screwdriver at its base and pull it out. If it is not stuck, it will come out in just a simple snap. The engine on Eager Beaver 2.0 is held with the help of three bolts. Locate the three bolts and unscrew them. You will need a 5/16 screw key for this purpose. When the three nuts have been removed, the engine is free from the case, and you can take it out. Remove the choke lever by unscrewing the bolt holding it. Squeeze and hold the trigger with one hand and grab the engine with the other. Pull it out. If it doesn’t come out, check if any wire or cable, or spark plug is getting stuck. Take care of it, and then pull the engine out. Now every component of your McCulloch chainsaw is unhooked from the frame. You can identify the problem and get it sorted out. If you want to open the engine or carburetor, you will have to open all the bolts and analyze their working. If you are not an expert in mechanical stuff, it is best to take them to a chainsaw mechanic nearby.
