Third Function Valve Kit TVK-YL610P for YL610 on YT347/359

Third Function Valve Kit for YL610

3.5.4  If SCV lever is out of adjustment, adjust the Adjustment 

Nut in or out until you get free movement of the clevis pin 
in its slot.

(1) With the SCV lever in the neutral position and the lock 

engaged, remove hairpin clip (A) from the linkage retaining 
its clevis pin and check to see if the clevis pin is moving 
freely.

(2) If it is too tight, the Adjustment Nut will need to be adjusted 

until the clevis pin moves freely in its slot.

Once the clevis pin moves freely in its slot, reinstall the hair pin and check to see if the neutral position and SCV 
Lock can be locked in Neutral.
