If your 55k is a 67 then your serial # must begin with 61H. If that's the case then you have the D330 engine which didn't last long in the 55K and L series machines. It was replaced by the 3304 which was a much better engine. The later 3304's had the reversible fan from the factory, it held up much better because the fan wasn't attached to the water pump shaft like yours. In the 3304 the water pump was gear driven not pulley driven like yours. The reason the reversible fan wasn't usually found on your type was because the water pump shaft wasn't strong enough to handle the extra weight of the reversible fan. The engine in your machine is the same one found in the older 955H.
