[quote=&quot;John Schwiebert&quot;:2y1ilu6i]O. K. On the headgaskets, the 158850 was the standard head gasket for the 1750 gas engines. The 159320-As was developed to solve some head gasket problems with the B &amp; C 1800 diesel engines. I can fax you a copy of the service bulletin. I will look up the specs and it will probably be tomorrow. I go to the eye doctor today and by the time they get done taking pictures and all that other stuff with my eye I will not care about or be able to see anything the rest of today.[/quote:2y1ilu6i]

Weather here has been raining, so didn'y get head pulled, tractors outside. Still looking for head bolt sequence, torque specs.
Also Jensales has manuals for this tractor which one is the service manula with things like head torques, disassembly-reassembly of tractor sections for any future problems as they arise??
