Howdy, we have an older 1970s vintage 930 wheel loader that has to sit an idle 30 min before it will move. It developed this problem a couple of months ago and I just thought the oil was super cold. Now that its 60 degrees it hasn't improved. Sometimes it starts to move then acts like it in neutral, but after ideling around a while it works perfect. I'm getting ready to change the oil and filter which has 250hr on it. What else should I check? I'm going to order a service manual off cat tomorrow, any advice wold be appreciated.
