Hoping that someone can help me out. I have a 2001 CAT 304.5 excavator which needed the front wind screen replaced and fitted. I know know why he didnt hang around for me to arrive. A message was left which said "somebits missing! but ive done it its just abit stiff. Well stiff is an under statement, i would probably say seized solid not moving and open!! Does anyone have a detailed diagram on what bits i should have and how to fit it correctly. Thankyou.
