Throttle Bellcrank Friction Disc Spring Washer

Mornin',
While replacing the battery box on my 860, I noticed the throttle bellcrank friction disc spring washer was partly disintegrated. The governor compensating spring had never been there since I've had the tractor so I decided to replace them both.

My question is, how do I know how tight the spring washer nut should be? The new compensating spring is very tight and, while I never really had any issue with it, the throttle seems the same. Maybe I just lucked out and installed the spring washer with the proper tension? I'm just starting to wonder why I even spent the money to replace them if they don't seem to be doing anything.

Thanks.

They have a purpose. You must have been blessed to get the tension correct.

If they weren't there, your throttle would not hold position. It would be constantly drifting towards idle.
 
Hi Larry,
Thanks for the reply. The throttle doesn't drift but it didn't drift before and there was no governor compensating spring. That new spring has so much tension on it that I figured I'd feel some difference vs there not being a spring there previously. When opening up the throttle, the RPMs surge back and forth for a second before settling so I thought maybe that would be smoothed out with the addition of the spring. Oh well, as long as it sounds like adjusted properly, I guess it's good. Thanks again.

Tension on the friction disc may have been tighter before, even though the spring was not in pristine shape. Glad it works.


The little bit of surging would have nothing to do with the bellcrank end of things. Possibly it could be helped a little with adjustment of the governor spring. If it's just on startup, I'd not worry about it.
