I am in the process of refreshing the top end of the referenced engine and I am measuring the crankshaft end float with the flywheel on the engine (haven't removed it yet) using a dial gauge magnetically mounted to the flywheel and and resting against the crankcase. I zero the dial gauge and pry the flywheel outwards using two large screwdrivers 180 degrees apart from one another until resistance is felt and the reading on the dial gauge is stable. I am getting a consistent reading of 0.006 in., against a specification maximum of 0.0051 in. per Haynes manual. Do I need to add a shim, or is this close enough? I will be replacing the flywheel with a lightened one, but wanted to get this measurement prior to removing the flywheel that is on it. I will replace the rear main seal when I replace the flywheel, but the measurement I'm now getting shouldn't be affected by the new flywheel, or will it? Photos of the zero'd dial gauge and the extended end float reading dial gauge are below.
  Next question is about my oil pump. My engine gasket kit came with one paper gasket that appears to be for the oil pump outer cover. All the diagrams that I see for oil pump covers are not flat like mine, as pictured below.  My oil pump also has a paper gasket that is identical to the one for the outer cover that goes between the oil pump housing and the crankcase, while the diagrams seem to show an o-ring being used to seal the oil pump housing. Below is a photo of the mating surface of my oil pump housing.  The oil pump housing on my engine has no groove to accept an o-ring and used the paper gasket just like the one for the cover. Do I have a different oil pump on the engine? If so does anyone recognize it and can tell me about it. Thanks! |

You have a type 1 oil pump, looks to be cast iron which I've read is often made by Shadek. A type 1 pump would be a 26 mm or 30 mm I believe, where the type 4 pump is a 24 mm. The type 4 pump is aluminum and is one piece and doesn't use a cover so the kit just comes with the 1 paper gasket. The type 1 pump uses the same gasket 111 115 111 B between the body and the case, and another gasket between the cover and body 111 115 131 B
