Major thanks to my friends for identifying this part. Apparently my skillset for searching for answers on my own is slipping a bit!

This is for an IO-470F, however the same clips appear to be used on the IO-520.

Anyone know of a source that sells the Continental injector line hold down clips. I need to replace a few of them but having a hard time finding them as a separate item from TCM. Maybe there is a part number, but I can't seem to find it. Thanks in advance!

My new project is building a 3D model representative of an instrument panel and all of the associated structure that sits behind the panel. Of course I want to populate this panel with accurate models of the various instruments and avionics. Does anybody have knowledge of an existing repository...

First of all, let’s not consider mid-50s “late in life”. I’d really like to have those 15 years back, but I live by the attitude that there is still a lot of future to live for. I’ve been wrenching on airplanes for 50 years and do not have an A&P ticket. Until recently this was never a problem...

Dan your information is very valuable and completely logical. Hope the OP can solve his problem. I'm going to follow your advice on the ballast resistor. I will also follow the installation instructions from the 182 manual since I do not have, and cannot obtain, the details of the installation...

Every time an electrical load hits your system there is a mechanical force generated when your alternator responds to this. I had a situation where my anti-collision light (still using incandescent lamps) was placing a sudden load on my alternators every few seconds. I was surprised at the...

Anyone have access to the install manual for the GNC-215?

Thank you Dave, nice tribute to the spirit of American innovation. Find a need and then persevere to fill the need.

A question for the engineering arm of the POA brain trust. I’m trying to understand how an instrument shop calibrates an airspeed indicator and also to find the associated tables of pressures. It seems that this would be very simple if all an airspeed indicator concerned itself with was the...

Quick update - I have been persistently reaching out to Hartzell in addition to the STC owner attempting to obtain documentation on the correct installation configuration. I was pleasantly surprised to actually receive a personal response from Hartzell with the promise to conduct some research...

Picture of the mounting bracket below. I'm assuming all of the black dust is from the brushes. Hi Dave - good to cross paths... hope all is well! Part of my conundrum here is to understand the role of a rubber washer or rubber bushing. Does a rubber part even belong in this assembly? If so is...

Thanks for the feedback! This alternator was installed about 550 hours ago as a generator to alternator upgrade on my Commander 500A Colemill. Engine TCM IO520-E. I agree that someone likely mixed up some of the parts and that's what I am trying to figure out. Even with the vibration problem the...

Noticed my alternator (ES-4011) has a fair amount of movement in the lower bracket attach point contributing to excess vibration and wear. I pulled the unit and examined all of the mounting hardware and discovered several problems as shown. Trying to find an assembly drawing but Hartzell tech...

Very helpful - I might be able to use these. Thanks!
