Clutch Rebuild-Manual Transmission
I purchase a 100 with a 42 inch mower deck and front blade at an auction in the fall of 2012.
http://i152.photobucket.com/albums/s...0100/rd003.jpg http://i152.photobucket.com/albums/s...0100/rd001.jpg http://i152.photobucket.com/albums/s...0100/rd002.jpg http://i152.photobucket.com/albums/s...0100/rd004.jpg This 100 is one of the quickest starting garden tractors I've own. When you tried to engage the mower it acted like something was in a bind and not letting the mower blades spin. The problem ended up being the pulley was against the mule drive. The welded nut inside the frame was missing and the mule drive was bent. Only way to fix it was to remove the engine. The clutch between the engine and trans was acting up too (someone installed a wide frame clutch). While I need to remove the engine to weld the nut back on I will fix the clutch too. Removing the clutch is easy to do if you follow your repair instructions in your Cub Cadet manual. I had an extra narrow frame clutch to use. Narrow Frame Clutch Assembly: http://i152.photobucket.com/albums/s...ps7f662eb6.jpg I wanted to take clutch assembly apart to make sure everything was ok. Here are the special tools I use to disassemble/assemble a clutch assembly: http://i152.photobucket.com/albums/s...ps8bdad51f.jpg First thing I notice the throw out bearing was froze up. One of the first things I do is to remove coupler joint between the trans and driveshaft. I use my V-block to hold the clutch and hang the clutch disk over the edge: http://i152.photobucket.com/albums/s...ps7f508df3.jpg I use a spiroid pin punch to drive the pin out. http://i152.photobucket.com/albums/s...ps957c4c7b.jpg Notice the pin is over the edge so it has a place for the pin to go. |
Notice the location of the pin in relation to the V-block:

I will turn the clutch assembly end for end to use my jig to remove the pins. http://i152.photobucket.com/albums/s...ps24598f1a.jpg Closer view: http://i152.photobucket.com/albums/s...ps135c702d.jpg Front pin being removed: http://i152.photobucket.com/albums/s...ps09662b59.jpg |
Clutch assembly is apart. Here is what the clutch disc looks like:
http://i152.photobucket.com/albums/s...ps2eeeb57f.jpg The pile to the right of the clutch disc is part of the clutch disc. Pressure plates: http://i152.photobucket.com/albums/s...psda0b6ab2.jpg Release arm: http://i152.photobucket.com/albums/s...psc94b8e26.jpg You need to look for excessive wear where my finger is pointing to: http://i152.photobucket.com/albums/s...ps0d968f6b.jpg This release arm is in good shape. The area where my finger is pointing to is where the throw out bearing goes. http://i152.photobucket.com/albums/s...psfc1a614c.jpg The driveshaft needs replace. Tomorrow we will make a list of parts that need replace. |

One of the main reasons for this thread is to show how easy it can be to rebuild a clutch. |

I'm not a big fan of using a press. The tool I use can go to an event and is much easier to use than a press. |
The last item I check out is the 3 pin driver.
http://i152.photobucket.com/albums/s...psdaa68f30.jpg The picture shows the wear on the pins. Worn pin(s) will make the holes in the clutch disc go oversize and the pins could shear off. It will make the clutch go out of balance and the tractor will have the shakes. I will replace the bushing in the 3 pin driver too. |
Parts that are needed to rebuild the clutch assembly
