part # help (fuel related)

[eman1200]

hi.  can anyone help with part #'s, '75 M20F?  thanks!

So, the nut plates are just standard nut plates, with a couple of notches ground in the sides with a Dremel. They will probably be $200 each from Mooney, Or you can make them for $5 each. What is wrong with the pickup tubes? I would glue the finger screens back on with sealant.

I’m trying to see if the quotes from the wetwingologist dude are in line. Part #s will help me do that.

The part numbers should be in the IPC

[N204TA]

The fuel pickups should be  610150-001 (Left) and 610150-002 (Right)

The drain valves are F-391-53-S

 

Wetwingologist has done my tanks twice and I trust Edison not to take advantage of you on the cost of parts.

thank you.  so for the drain valves did he charge you the roughly $50 (maybe plus markup) or significantly, incredibly more than that?

The labor to re-install new nutplates for the new sump drains will be the more significant cost. People loosen up the nutplates by over torquing the drains.

Not sure i understand why or our how ellison explains it, but through my Savvy clients i know that the up charges for drain replacement is often miss understood by owners. It is an extra job that needs to be done when the nutplates have been over torqued, but not for just a plain reseal.
I think he should go over possible add ons when people drop off the plane or raise the baseline price and then give a discount if they don’t need replacement since some people are left wondering what’s going on. But it’s nothing really surprising except not learning about it till mid job or later.

Do anyone have part numbers for the nut plates?

The standard nut plates unmodified! I can do the notch modification and save the $$$ for other required parts.

Not sure of the thread size or rivet spacing, so you should double check.

Those nutplates look like they could be cleaned up if they're hard to find.   The drain plugs are not difficult to get.

@eman1200, have you discovered this yet?  See page 190 (PDF page 176).  Cheers!

I have but admittedly I'm not great at reading it.  but also I can't really seem to find much online on say part #610150-001/002.  but thank you for the link.

[Lumberg]

I dont suppose Im good at reading either.   I just saved it for the pictures....not the articles (hehe).

Following. Cheers!

For some items there's a part number like that, and it's a Mooney part number if it's something that the factory made or supplies exclusively.  For the nut plates if Mooney ground the drain gaps into it, it's not something you can buy off the shelf so it has a Mooney part number.    The trick here is to find the standard part and maybe just grind the drains into it yourself.

For many items there's a standard part number, like for a nut or bolt or washer or bulb or whatever.   And for many other items there's a manufacturer specified and the manufacturer's part number.   The catalog is really useful that way to sort out what's needed, but in this case it's something that was evidently modified at the factory from a standard part, so it has a factory part number.

And ‘sometimes’ those factory part numbers can be found online with new part #s, sometimes not. Like an alternator part # I had but was no longer made, I could still trace the old part to the new part #. As for doing this particular work myself, the plane is already at Wetwingologists. He doesn’t strike me as a “let me see if I can fix it” guy, he’s a “replace it with new or I’m not signing off on it” kind of guy. Therefore I just wanted to see if I could compare prices online.

Thanks!

Yeah, I recently spent a bunch of time tracing several generations of obsoleted part number to find a gasket.   The part number in the IPC has been obsoleted and replaced, that part was obsoleted and replaced, etc., etc., for several generations.  Finally found what an equivalent current part number is and there is still a supplier since it is still used on some corporate aircraft.   Many times the parts are just obsoleted to the point that nobody makes it any more since the technology itself is obsolete, like the fiberglass materials specified for M20J cowls.   Keeping old airplanes flying requires some creativity sometimes.   The parts catalog for the aircraft is usually the best place to start, though.
