310-8 clutch issue

[Nick009 2]

So long story short I put a new drive belt on (5/8in x 81in) and now the clutch doesn’t do anything, it just rubs the top of the belt. I’m not sure if I installed it correctly or if it’s that little white switch that’s the problem. Here’s a video of the problem.

Install the belt guard and try again

Welcome to Red Square.

Should it not be 5/8" x 82"?

Post your model and serial number if you need help.

The belt guard is an essential part of the clutching system. 

when you step on the clutch, the belt guard funnels the slack to the engine pulley, so it doesn't grab the belt.

I just realized there is no sound in the video, sorry bout that. I didn’t know that the cover did more than just cover the belt and pulley. I will put it all back on tomorrow and see if that works then update. I bought this machine off the side of the road so I’m still learning about it.

The idler pulley should move forward until the belt tab on the pulley locks the belt against the stationary tab.     If the idler pulley is not moving when you depress the clutch, the i/8" roll pin that fixes the clutch lever to the crossover shaft may be sheared.    The belt should be 5/8 X 82.        

Here is a video of a 310-8 with an 82" belt.

I'm not sure what switch you are refering to.    Search the manuals section for your tractors manual.

 

Here is a link to the 310-8 that I picked up,

My clutch does push the belt against the stationary tab but it keeps spinning, I used an 5/8x81in but perhaps I will switch to the 82in to give it more slack to grab.

The 82" belt should help and installing the belt guard will also help.   Although as you can see in my video, my belt stops with the belt guard off.

With the 82" belt, the idler will go back where the angled plate contacts the clutch damper cylinder.  The adjustment details can be found in the manual.

UPDATE: switching to the 82” in belt worked, everything is fine now. Thanks for all the help, ignore the copy and paste error above I can’t figure out how to rid of it.

Thanks for the update Nick.

Glad you got it working.   FYI;   the little white switch is your clutch switch and it allows the starter to operate when you push down on the clutch.

Unrelated to your issue @Nick009 but in your video it looked like your belt was touching the brake rod that connects to the brake pedal. Is that true? Just curious as I noticed on my 312-8 my belt rubs the brake rod and trying to figure out what's going on...

 

PS I have the same blue belt, 82", and it works perfectly

Once I put everything back together with the 82” belt instead of the 81” I have had no issues. I didn’t notice the belt rubbing on anything it’s not supposed to however it does run very close to things, enough so that it makes me nervous.

I'm in the same boat haha, my belt is just barely touching my brake rod so I"m thinking of dremeling the side of it just 1/8" to give me a bit of clearance. I'm a worrier!
