[QUOTE="Cyborg, post: 130470, member: 3426"] I know there are several methods for priming rebuilt engines, or engines that have been sitting for years. Someone can add a photo of the (drill driven) modified oil pump or if not I’ll dig one out. Been staring at this bottle sitting on the shelf for about 5 years. It is meant to use as a refillable aerosol can. Comes with a variety of spray nozzles and costs around $40 CAD. A cheap alloy water bottle would do as long as the cap could be modified to hold 40 psi safely. 2/3 full = about 150cc and a 40psi charge is enough to expel all of the 20/50 oil. The valve (surprisingly) was easy to modulate and a during its test run it took about 45 seconds to move the 150cc. The hose will be replaced with clear, so the valve can be shut off as soon as air appears. This will take care of the crank and cams. A different fitting can be used to slowly push oil back through the return line to feed the rockers etc. Not sure if the filter housing will need separate attention. It was relatively easy to use the existing aerosol fitting as a pattern to make a new one with a groove for an o ring and threaded for a pipe fitting. One option, not necessarily the best, but won’t make a mess if the pressure is kept to a reasonable level. [ATTACH type="full"]38579[/ATTACH] [/QUOTE]
