RE: RAM500, different pump, help.
I have the new nut for the larger bendix. I built a hand held wand starter (see pictures My wand starter worked on the bench at home for several starts. My goal was to reduce the airborne weight as much as possible by using the wand starter and off board propane tank.
The original shroud around the bendix is a very loose fit and that is the way I made my first wand. The problem comes when you forget to have the wand starter on the engine, you shut the engine down and it starts through the cool down phase with out the wand starter on the engine. Because of the loose fit and the mass of the large bendix it tends to whip and can even bend the motor shaft.
This week I built a new shroud around the motor with a very tight fit. Now the problem is I haven't been able to get a good enough alignment of the bendix in my wand starter and it binds when it extends to turn the compressor on start up.
I finally decided to accept the weight penalty of the on board starter but I need the new nose cone, the starter housing and the mounting standoffs the fit the large bendix and the matching nut.
I thought some one might have the parts I need from a scrapped engine. New parts to do the conversion back to on board start are very expensive.
I have started the engine just hand holding the starter motor with the bendix installed but I don't feel comfortable with my hand that close to the engine when it lights the propane.
See pictures below. The fod screen is hinged and flips down in place after the engine starts.
