There is a threaded plug on the top of the rear (cab side) cover that gives access to the pinion adjustment. It's a bear to get in there but it's better than having to take the whole pinion assembly apart.
Sir, thank you. I was hoping there was some access short of removing the whole thing. I watched Squatch253's videos of him rebuilding the entire pinion assembly but just so I can get by until I assess what I'm going to do I was hoping to get it functional in the mean time. I actually bought a complete running and a complete non running (but both engines are supposed to be good) grader so I hope to get both running and keep the best of the two. Thanks for your help.

My local mechanic agrees, latch adjustment is not fun on an 8T grader. Mine has the "in seat" start controls from the operators platform, which are even harder, as it is a single mechanism vs a clutch and pinion lever. JM
