I was told by Tom at O'Brien County Implement that some people put a 1955 starter on to spin it faster. I was told by some mechanic in Missouri that if the 1550 valves were ground and seated and the tappets adjusted just right it would be hard starting. I have set the tappets. I have a water heater in it but haven't tried it yet. Won't start in my heated shop without ether, though. Thoughts? [Reply]   [Send Email]

Not saying you aren"t right, just wondering if it applies to a different engine. I"m green as grass on the 1550 diesel.   [Reply]   [Send Email]

If they ground the valves and seats I know the recession is out of spec. Also 1550's had seats in the intake valves from the factory. I would have a good machine shop get the intake valves set to the correct recession,then have them measure the intake valve stem height and set the exhaust valves to the same stem height since there is no published dimension for exhaust valve recession. Have you checked the starting circuit with a good voltmeter?   [Reply]   [No Email]

It can make or break those tractors. A high torque gear reduction starter, good group 31 batteries, and 2/0 cables usually them a completely different ride.   [Reply]   [No Email]

If every thing is up to specs., Only solution is new valves and installation of valve seats to the correct dimensions.   [Reply]   [Send Email]
