Got a little more done tonight...assembled the 70E cases and installed the oil pumps in both the 49SP and 70E ......not a lot of time. But forward progress none the less. I tried to cover the oil pump install...the pics are of the 70E but it is exactly the same process for the 49SP and the parts are the same for either saw.
039 70E flywheel side case half and gasket prepped for PTO side install.
040 Oil pump body, retainer, two retainer screws, pump adjuster and its alum retainer. (all new OEM O-rings on both pumps)
041 installing adjuster screw and alum retainer.
042 Oil pump body lubed up and ready for installation.
I used an acid brush with a little straight Stihl Ultra to lube the main breaings and big end rod bearings after the cases are bolted together and the seals are in, also all parts of the oil pump and adjuster as well as the holes in the case where these items go. One reason for doing this is lubrication the other is rust prevention on freshly cleaned bearing surfaces.
