Hi and welcome to the site
I cannot give you the valve clearance as I don't know it and I have not worked on one of these machines, but as a rule of thumb; remove the engines rocker cover, make sure that the engine stop is engaged so that it cannot start up, carefully rotate the engine until you see that any of the cylinders has the two rocker levers free which means that cylinder is on the compression stroke, then set the valve clearance for that cylinder, repeat the process for the other cylinders. Some engines may have a greater clearance for the exhaust valves so you would have to look and see which part of the manifolds align with each rocker lever, for example the Cummins NH/NT range of engines which I was used to working on had an exhaust valve clearance of 0.023" and an intake clearance of 0.011"
Hope that makes sense.
