1st Issue: Servo??
Grizzly physically engages in Diff lock but will not disengagewhen button pressed to change to 4wd or 2wd. No movement of servo motor isheard at this point. As per step by step instructions on the website 501parts.com,I checked switch, relays, and servo motor and all is good. Once servo motor isremoved from front differential, pinion gear rotates as requested when buttonsare pressed. (completed numerous times). Note:I noticed that the slide rack that the pinion gear meshes with to move from 2wdto 4wd to diff lock sticks intermittently and often will not go all the way tothe far right position in the differential.
2nd Issue/Concern: Differential???
Physically removed front differential from grizzly andplaced on the bench. I manually activated the slide gear, by hand, to move itto the 2wd drive position, (Left side), 4wd position, (middle) and 4wd difflock, all the way to the right while slowly changing rotational position of thedriveshaft to allow for gear tooth alignment. Over many times moving the slide rack back andforth, I noticed that it would stop solid and not advance all the way to thefar right, (approx.. 0.150” away from end) and less than often it would advance to its far rightposition, (very intermittent). In this position, the internal female spline on thecollar gear was engaged with its mating male spline for 4wd but the outsidemale spline on the collar would not mate with the female spline to allow it tomove all the way to the right.
1) Is thisnormal operation for the diff? Is there a mechanical issue with the diff?
2) Once installed on the bike, Why will the servo motor not move out of diff lock as outlined in 1st issue above? Not enough power?
Please see pics below, rotate clockwise to view. I have a video but don't know how to upload it.
Any advice please, I am stumped.
Thanks,
Craig
