13 Pro knock on takeoff

[bgs8379]

Went for a ride yesterday , about 50% of the time when i hit the gas to take off it will have a single knock noise from the clutch side. It is almost the same noise as when you shift to reverse .Has anyone else noticed this ? or know what the problem is ?

The Team secondary usually locks into place in reverse. You have to move forward to get it out. If you ever have tried to open you clutch to remove a belt right after backing up, you know what I mean. It will clunk when you move forward, but only after you have been in reverse. Does it happen EVERY time you take off?

I should say, if it happens, can you stop and make it happen again while continueing to move in the forward direction?

Mine does it after I coast down a hill too, nothing to worry about.

It is the reverse notch in the helix but you can eliminate the noise in 2 ways.

1. lower your engagement rpm with a different primary spring
2. change your drive belt to a wider belt (re-shim your primary possible)

I too have had gone crazy with this nasty clunk and after riding doo for 16 years and think it sounds a bit junky. I had it really bad when I ran a Dayco belt and found the stock belt was a bit wider. Noise is almost completely gone now with belt change.
