Hi Guys, I have a ditch witch skid steer, and recently have noticed a leak whenever Im going in reverse. I have narrowed it down to a manifold, and in particular a bolt, which according to the parts manual is the divider/combiner manifold to the rear wheels. The question I have is whether the bolt (arrow) is adjustable and would stop the leak if tightened. Thanks in advance! http://www.thepicturehost.com/pictures/4047fc62278afe6cb634191fa2219757.jpg
