WHY DOES THE TRIGGER PIN NOT FIT INTO THE BEARING?
DO NOT FORCE THE TRIGGER PIN INTO THE BEARING!
Did you try a different trigger pin? The bearing has an ID of .125" and the pins can range from .125" - .126" so the pins can be .0010" too large, causing the problem you have now. They don't make bearings with .126" ID's, they only come in .125", so we have to deal with this issue, but it's an easy fix.
You may have to lightly sand the pin down so it fits into the bearing. Take the flat trigger plate and put the pin in it. Grip just the pin with some sand paper (120 grit or so) and then spin the plate around a couple of times. This will turn the pin down. Lightly sand the pin until it fits inside the bearing. Spin it a couple of times and test fit. Repeat until the bearing easily slides onto the pin.
If you popped the bearing out you can easily pop the bearing back in the trigger. Just line it up with the hole and use the flat side of you trigger plate to apply even pressure to the bearing and push it back into the trigger.
MY TRIGGER DOES NOT RESPOND TO THE EGRIP
There can be 1 of 2 things happening here.
First, check the orientation of the magnet. The HE sensors need to read the north pole of the magnet. There should be a red mark on the north side of the magnet. I periodically tested triggers when I was installing the magnets, but it is possible that I could have put the magnet in the wrong way. All you have to do is remove the magnet and install it the opposite way. Be carefull with them, some of magnets fit tighter than others and the magnets can chip or break if you push on them too hard.
You may need to adjust the HE sensors on the board. Even with my stock trigger I had this problem. I had to pull the trigger at an angle to one side or the other in order for it to trip the HE sensor. The HE sensors on the board may need to be pushed together a VERY TINY BIT. I tweaked mine by pinching the HE sensors together ever so lightly. This fixed all of my egrip issues.
TOOLS REQUIRED: 1.) Phillips Head Screw Driver 2.) Flat Head Screw Driver 3.) Allen Wrench
STEP 1: Remove the four screws holding the grip together. Then remove the air source adapter (ASA).
STEP 2: Disconnect the battery and remove the board. You will need to remove the plastic case that is protecting the board. Using your flat head screw driver, push in on the small tab holding the two halves of the plastic case together. Once the tab is loose gently remove the baord from the plastic case.
STEP 3: BE VERY CAREFULL WITH THIS STEP. You will notice two black sensors sticking up from the board that are facing eachother. These are the hall effect sensors. In order for your trigger to work properly these sensors need to be parallel to eachother. using your thumb and your index finger, GENTLY pinch the sensors towards eachother.
Just pinch them together a TINY BIT. Once you feel them move that is enough. You do not want the HE sensors sticking out past the edge of the black plastic case. Put everything back together and test fire your trigger.
