berriesandnuts 1 #1 Posted July 20, 2020 Had to replace the drive belt. Got everything back together, but had a lot of trouble getting it to go into gear with grinding. I thought maybe I didn't put the belt back correctly. But looking from underneath, I'm noticing that when I push the clutch pedal, if you look at the picture I'm attaching (with my markings), the round thing moves, but the rod it attaches to (see other arrow), doesn't move. I'm assuming this is not normal? It looks like when you press the clutch pedal, it's supposed to turn that rod, which is connected to a bracket on the pulley? That bracket is barely moving. It looks like it should press down on the belt. Not sure what to do about this? It's a 416-8 wheelhorse (or so the sticker says). Share this post Link to post Share on other sites
pfrederi 17,868 #2 Posted July 20, 2020 If the clutch is out (engaged) in that picture i would say your belt is the wrong size looks too short. 4 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,096 #3 Posted July 20, 2020 It is possible the spirol pin item #17 has sheared off. Item #17 is part number 933190 and is a 3/16" x 1-1/4" spiral pin. Similar to a roll pin but multiple layers of spring steel rolled to form the pin. A roll pin is a single layer of metal. https://www.partstree.com/models/31-16k804-416-8-toro-garden-tractor-1988/clutch-brake-and-speed-control-linkage-5/ Garry 1 1 Share this post Link to post Share on other sites
The Tuul Crib 7,337 #4 Posted July 20, 2020 I had the same problem with the green belt that I ordered a while back. It was too small by an inch. Share this post Link to post Share on other sites
Ed Kennell 38,647 #5 Posted July 20, 2020 The belt does look a tad short, but if you operate the clutch pedal and the lever moves but the cross rod does not move, the spiral pin connecting the two has to be sheared. Put a mark across the end of the shaft and the lever. Look for movement as you operate the clutch. Share this post Link to post Share on other sites
berriesandnuts 1 #6 Posted July 21, 2020 Hmm. Should've kept the receipt for the belt! Or at least thought to compare against the other. But in any case, no movement on the rod itself when I have my wife stomp on the clutch pedal. I'm try to see if I can disassemble enough to see if I can inspect the pin.

Bill D 1,933 #7 Posted July 21, 2020 (edited) If that is a TSC belt and you still have the sleeve, they usually will take it back without a receipt. Since I see you are a local you may want to call Reardon Briggs and see if they have the belt. Unfortunately they aren't the cheapest source for parts Many people here use OEM drive belts because they tend to fit better. The drive belts for the 8 speeds usually need to be slightly longer than the whole sizes found at TSC. I was able to make an 84" belt work on one of my machines, but an 84.5" would have been better.

You may have to remove the cross shaft to get the pin out. Here is a tip I found to help keep the holes aligned during reassembly. I drill and tap the lever for a set screw to hold the shaft and lever pin holes in alignment so when I drive in the new spiral pin, I know the holes are aligned.

The pin was partially sheared. Had some trouble getting it out too. Curious where you got the spiral pin from? And, did you use a regular hammer to drive it in?

Ed Kennell 38,647 #10 Posted July 23, 2020 ACE hardware or TSC may have the spiral pin. If not, McMaster Carr on line. I use the flat end of a small ball peen hammer to drive the pin. Again I drill and tap the lever for a set screw. Then assemble the lever and align the pin holes with a small drill bit. Then tighten the set screw to keep the holes aligned while I drive in the spiral pin. Share this post Link to post Share on other sites
