C oil cooler frame?

[Brian2034]

Looking for part number and or where to purchase oil cooler mount / housing for a C.

There is apparently a heavier version available but I can’t seem to find a part number or vendor.

Or maybe someone has one sitting on a shelf and might want to sell.

Its the rounded piece riveted to the lower cowl

My logbook says I installed pn 650017-000, Rev G, way back in 2010.  They didn’t roll the part number for the thicker bracket, just the revision letter.  You are correct, Revision G is made of a heavier gauge aluminum.  LASAR sold me the part.  If they don’t have it in stock, they can probably source it from the factory.  Or, you can call around.

Great

Thank you, that’s what I was looking for.

 I know this is an old thread, but is there any possibility you remember if you had any issues mounting the cooler to the four bolt pattern in the new part? 
I have a revision G that two of the four bolt holes are approximately 1/8 inch off. Your photo looks similar to mine.

Got a picture?

Are you saying that the holes in the new part (rev G) don’t match up with the old part you removed from the lower cowling?  As I remember (from 2010) the holes in the new part were the same as the old part.  The oil cooler bolted right up.

However, as you can see (below), there were extra holes drilled into the mount flange of the oil cooler to match the holes in the cowling.  You can see some of the holes on the flange look elongated from the factory.  If your holes don’t line up exactly, I’d work on the holes in flange of the oil cooler before I removed metal from the mount in the cowling.

(Please, don’t anyone yell at me for the self-locking nuts on the exhaust ball-joint hardware.  That’s the way the airplane came to me.  I’ve since replaced the exhaust with a new PMA exhaust.  I was considering a PowerFlow, but I’m still running a generator and I would need to do the alternator conversion to make the PowerFlow fit.)

The photo of the new part setting on top of my old part has penciled in dimensions, and printed dimensions are what I received from Frank as what it’s supposed to be.

That’s a hot mess.  

First option, does Mooney (LASAR?) have any mounts in stock that they can trade for the one you have that’s miss drilled?

Second option, what does your A&P/IA say?  Although the holes in the new part are spaced too far apart, removing any metal will weaken the mount.  If you can’t get a new replacement from LASAR, I’d still vote for expanding the holes in the oil cooler flange to match the mount.  You’ve obviously lined up the oil cooler to the new mount… the goal would be to center the fins of the oil cooler in the opening of the mount and then see which holes in the oil cooler flange need expanding.  If your A&P/IA agrees.

An exchange part would be your best option.

That’s the route I have to go at this point. The part is NOS that was sitting on the shelf somewhere on eBay with the correct part number, but no supporting paperwork. IA scratching his head along with me. Frank couldn’t trace when and where it was made with only the Part number etching prior to me spraying primer.

six week lead time.

That’s a bummer… hopefully, eBay will give you recourse.  

Is your old mount beyond repair?  I’ve seen some mounts with very elegant patchwork, compound curves and everything…

It’s the thinner one that’s been work-hardening and cracking. 
 The new one I picked up some time ago and never checked it against the cooler thinking why would that dimension be wrong but here I am.

 Sometimes great deals are not so great when visibility improves.

It sucks when you’ve done nothing wrong but still draw the short straw.  I’m thinking this NOS was built by Mooney, and then languished on some MSC’s inventory (perhaps for decades) until it ended up on eBay.  Obviously the factory’s quality control was lacking at the time it was manufactured.  There could be something nefarious involved, but I doubt it.

This isn’t a deal breaker.  You’ll get it straightened out and 10 years from now it will almost surely be just a distant memory.  Many (most?) of us have experienced maintenance issues that went sideways.  Keep focused on the brass ring.  You’ll get there.
