Changing cutting blades and knives on my w-w grinder wood chipper model 204(how is it done?)

Question edited and turned around for clarity.
Question moved from Cars and Trucks to a Wood Chipper Cat.

No torque specs, tight and use thread locker.

Try going back to basics. Yes, I've been caught out by something silly and obvious! Are they the correct OEM blades for that model? Are there washers/spacers fitted on the mount screws? Are they the correct screws? Have all the access covers and cutting guides been refitted correctly? Has the depth guide been set correctly?
Some planers can be fitted with thicker or thinner blades depending on the model. Washers/spacers may need to be fitted under the blades so they are 'trapped' and lift the blade high enough to clear the screws. Are the original screws 'dome head' or 'countersunk'? Domes will sit higher and touch the wood as the blade spins. The access covers, cutting guides and depth gauges could be out of position affecting the cutting platform.

Hi there's this website something like reliable-store and it is very amazing for manual for repairing servicing anything
someone on fixya recommended it to me and I thank him even today
They have full free manualsso whats the harm in trying

there is one more but i don't remember its name it was 2 years back bitman something link this
Try it out brother

This is the only source that I know of for the older chipper blades. Problem is you need to know the dimensions.

There is an MTD one that is for troy-bilt but was not able to match it up with your unit due to pub issues here on my end: PN is MTD 1901782MA

I recommend you contact these folks to get it sorted out:

Hope this got you pointed in the right direction.

Thanks for using FixYa.

most of these saws have a push/lock tab on back side of motor housing that pins the shaft for blade change. if you cant find, use a 4/4 wood block to wedge old blade so you can loosen bolt.. hope this helps....chris

It takes me about 5 minutes to Remove, Sharpen, and Re-install my chipper blade for my Bolens mc2500. First, If your using a screen or rollers in the discharge, then remove them. Look underneath, and you will see the thick flywheel. Make sure the spark pug wire is disconnected, then slowly turn the flywheel by hand until you see the two hex head bolts that hold the chipper blade to the flywheel. Also remember which way you take it off, so it goes back together the same way. using an open end or combination wrench remove the two hex bolts. Now to sharpen, I use a medium/ coarse honing tool made for lawnmower blades. I clamp the blade to the top edge of my Bolens with a pair of visegrips, then a little oil, and the sharpening tool, and I'm done sharpening in about 2 minutes, and then re-installing, reversing the removel process. I hope this helps.

Most of our industry refers to chippers or chipper-shredders as pieces of equipment that can handle both wood and leaves. These machines have both a chipping device and a leaf-shredding mechanism. This mechanism is basically a hammer mill, cylinder or drum with a series of pivoting flail-type knives. The chipper-shredder usually is a smaller machine and may include a vacuum to clean up leaves. These machines can be self-propelled or stationary. Most chippers are disc-type, consisting of a large, heavy, rotating disc with knives mounted to it and are for chipping wood only.

Maintenance (excluding the power plant) Your primary maintenance concern with chippers and shredders is their knives. You can re-sharpen chipper knives, whereas you can reverse shredder flail-type knives when dull but you can not re-sharpen them. You must sharpen chipper knives with special sharpening equipment because they are made of high-carbon steel. Maintaining sharp knives can lengthen their life and the life of the machine by keeping power requirements low. An over-dulled or chipped chipper knife will need extensive sharpening, which will remove a large portion of the blade. This obviously will shorten its life. As soon as a blade is slightly dull, you should sharpen it to minimize the amount of blade-material that you remove. All knives need sharpening at the same time to keep them in balance-even if only one is worn or chipped. Also, you must use matched sets to keep the knife the same distance from the anvil for proper chipping and feeding. After removing the knives, clean the area where they are fastened with a wire brush to make sure they will align correctly. Be sure to torque the knife bolts to their proper specifications. You will need to examine the anvil and be sure it maintains a good, square edge. Occasionally, you may need to remove and sharpen it.

Great input tina783. I have just one thing to add. Try to shred the branches within a reasonable amount of time. I found out that with my shredder, if I put older, dried up branches in, it tends to take a lot more time, as well as tosses chips back out at you. With newly cut branches, this wasn't nearly as much as an issue.

Use a pencil and straight edge to mark the cutting line on the wood. Place the wood on the saw table and line the mark up with the saw. Place the mark on the right side of the blade to ensure proper cutting. Plug the saw in and put on your safety goggles. Support the wood on the work surface with your left hand, placing it far from the saw blade. Place your right hand on the handle, and push the trigger to start the saw. Move the saw blade down onto the wood. Put constant pressure on the handle to slowly move the blade through the wood. Release the trigger and raise the blade once the cut is complete. Make diagonal cuts in the same manner, by marking the wood and lining the mark up just to the right of the saw blade. Continue as you would for a straight cut. Remove the wood from the saw. Unplug the chop saw and dust the sawdust off. Remove the dust bag from the back and empty it. Vacuum any remaining dust off of the saw.
