Hi all,
Bought a SAT-002 Aisin replacement locker for my front axle and tried to get it in this afternoon. I've had the locker apart twice now (to verify motor works on 9v and to make sure the internal gear assembly thing is "clocked" in the locked position for installation. I followed the below instructions that came with the actuator EXCEPT that on the removal phase the actuator was not installed. I had already removed the old crapped out one, so I turned the dial, moved the fork manually, verified locked on the dash, and then disconnected battery. Not sure if that could be buggering it up somehow.
After installation of the actuator, turning truck back on and turning dial off, the locker disengaged (verified with front axle jacked up) but will not re-engage. In fact, I enlisted the help of my 9yo to listen and the rear actuator makes a distinct noise when activated by the dial whereas the front doesn't. I spun the tires a bunch to see if it was trying to lock, but I'm sure when I pull the actuator again the fork rack will be in the disengaged position.
Not sure what I am missing. Kind of bummed because I had hoped this would be an easy swap and the FSM isn't super clear to me. The actuator motor works, the gears/springs work (you can see tracks in the grease from the contacts and tested springs with a crescent wrench on the output shaft), the fork rack can be manually moved to lock/unlocked, the locked sensor works as confirmed when manually locked it shows on the dash. I'm hoping someone knows what step I'm missing.
Will try clocking one tooth off in the morning. See if that works.
Happy weekend!
