We have Yale door closers Model Number 2002SB mounted on doors that open outward to the right. Unskilled carpenters mounted closing arms on frame to the left as you face the large Yale box containing closing mechanism and doors close with a bang. What can we do to slow down the closing and stop the bang that shakes house?
THERE SHOULD BE TWO SET SCREWS ON THE MAIN BODY MARKED C AND L AS U TURN THE CTHAT WILL SLOW DOWN THE SPEED OF THE CLOSING .AND AS U TURN THE L THAT MEANS LATCH ITSLOES OR SPEEDS UP THE LAST 6 INCHES UNTILL THE DOOR LATCHES U TURN IN THE SCREWS TO SLOW DOWN THE CLOSING AND ONLY TURN 1/4 TURN THEN TRY THE DOOR UNTILL IT CLOSEES PROPERLY
Since it isn't working you won't hurt any thing by trying to fix it. When closers wear out they will slam. If you see any oil leaking from it is worn out,& adjustment may not help. It would be a big help if you had a self help book with door closers in it. On some older Yale closers there is a little flat knob that can be turned with a screw driver or a pliers. Turn it a little clock wise & test. Repeat until it closes like you want it. If you can't get it to work right & you have turned it almost tight the closer may be worn out. If newer it may have cover over it which will be held by set screws. You will need an hex head wrench. It's best to have a set because the size is unknown at this time. Look on the body of the opener for the set screws. There could be 1 - 2 or 3 set screws. They may or may not be marked. If there are set screws on both ends the ones to the hinge side control the closing. Now for the fun part. at all times try to remember just what you are doing. If the screws are marked, tighten (Clockwise the one marked L) do this in 1/2 to 1 complete turns & check if it helps. Do this in several steps. Checking as you go. If this don't help. you have to try a different set screw. If it is unmarked you may want to reset the this screw back to where it was. Do this until it works or you just give up. If you get to the point where a screws is tight back off a little, the closer wont close if the screw is tight. Have fun.
