Where's the adjustment!!

> Dear Meli: How do you adjust the oil

Pay Attention!!!
    In order to get at the oil pressure regulator, you have to remove the crankcase cover. That is the cover AHEAD of the steering post, not the one with the shifter on it. If your B has the "long hood" and the starter, this is going to be a LOT of trouble! If it's a "hand start", it won't be so bad. You'll find the oil pressure regulator on top of the oil filter head assembly. (The entire assembly is shown in the exploded diagram at the right.) There is a lock nut and a screw on top. Loosen the lock nut and turn the screw "in" to increase the pressure and "out" to decrease it. The unfortunate thing is, if you have the starting equipment on the tractor, you have to put a lot of things back together to start it up and find out the results of your efforts. You'll want the oil pressure to be between 10 and 15 pounds, or "medium" on a John Deere gauge. This may take some trial and error... and I DO mean "trial"!!
    If you have a LATE styled Model B, after serial number 201000, the oil pressure adjustment is on the OUTSIDE of the tractor, just below the belt pulley.
