    Replacing Wing Fuel Drains

    Finally got around to it this weekend. They both came out super easy, threads in the tank were clean and undamaged. I ended up having a CAV-160 on one side and a CAV-170 on the other. Loctite 592 worked great.

    Slick tool for Handcutting Aluminum sheet

    Anyone have any suggestions for cutting a hole? I have an access hole I need to open up the diameter by 1/4" or so, not sure if I want to use a dremel and make a mess.

    Looking for a used set of 26" bushwheels. Prefer the newer & lighter 2.0 Airstreak but I'll consider any offers. Let me know what you have via PM. Thanks,

    Electrical System Troubleshooting Guide

    I'll look into it, thanks for the suggestion. I believe the C85/90 & O200 use a gear driven alternator while mine uses a belt driven, and I think that may be enough of a deviation to prevent being able to add it.

    Exhaust Stud Replacement

    You are correct. I realized this when I got the new studs and the nut would only bolt to one side of it. Thankfully crisis averted. Thanks for posting, I should have mentioned that for future thread readers.

    Thanks Brit, I'll give it a try. Unfortunately I don't have access to AC power at the airport, but I think I should be able to go through the same process with a fully charged battery.

    Electrical System Troubleshooting Guide

    The only alternator conversion STC I've been able to find is one that specifically calls out the C85, C90 & O200 engines. My C120 has an O-290, so *I think* my only option is a field approval.

    Electrical System Troubleshooting Guide

    Unfortunately I think it's time to give up on this. I pulled the voltage regulator and the only auto electric shop I found had no interest in working on it. He said he gave away his machine to test it years ago. I cleaned all the contacts and re-gapped them per the Delco Remy bulletins. I even...

    Exhaust Stud Replacement

    Thanks Tom Unfortunately I need the 5/16-18 Well it's not only because they are rusty. In trying to remove the nuts they seized and ended up pulling the stud out with them. Since they are out I feel like I should replace them. I don't see the point in reinstalling rusty studs/nuts. My...

    Exhaust Stud Replacement

    I'm going to be changing my exhaust gaskets to the no-blo type. Upon inspection it appears that the exhaust studs are due for replacement (rusted pretty badly). My plan was to chase out the threads with a tap as they seem pretty stiff. Besides that I plan to install the new ones with a little...

    Electrical System Troubleshooting Guide

    Thanks I have a PSU at work, might as well give it a whirl. Thanks for the help. Yea, I know this thread has spiraled out of control a little, but I do plan to do an alternator conversion before I update any avionics (mentioned in that thread). I can't do that at the moment because the gov is...

    Electrical System Troubleshooting Guide

    Unfortunately the only auto electric shop I could find in town didn't have his bench tester anymore. I'll have to see if I can adjust it myself, I think at least filing that point down will help.

    Photos attached, configuration is a little different than the delco remy bulletin. Gap seems pretty big on that second one.

    Electrical System Troubleshooting Guide

    Thanks I'll make sure to check that out. If that is the case, do you think I also need to pull the generator to get checked out? Or if I get the regulator worked out the generator "should" be unaffected?

    C120 Avionics Upgrades

    That's a nice unit, but for more than the garmin I'm not sure what it's getting me. And I don't want to ditch the NARCO completely because I use the VOR. The ADF on the other hand I'm happy to sell.

    Electrical System Troubleshooting Guide

    It's been raining cats and dogs here in SoCal. Today is supposed to be the last day of it, so I can get back to the airport tomorrow. If I can't get it to repolarize then I'll pull it off and take it to the auto electric shop. I've also been reviewing a few old delco remy manuals, trying to...
