For some reason Caterpillar has still decided not to put O rings on parts that obviously need a new O ring. It would be ok if they trained their parts personnel to inform the customer of this. Sometimes it comes with it and sometimes it doesn t. So here I sit with an 1800$ injection pump and no o ring to install it. Now I have to call and make more work, lost time and frustration for all parties involved. I am sure Caterpillar will Still do nothing to fix this problem. I just had to vent before I waste half a day get a stupid o ring. Thanks for nothing.
