Exhaust smells

Thank you Mr. George,
I have never had an original in my hand, do you know how thick the material should be?

An inner tube works just as good if you can find one.

Richard’s suggestion is a good one. Use the cover as a pattern, and for the gear-leg, just make a slit for the leg to pass-thru for a tight fit.

[prairiechicken]

Ha, I was wondering about an inner tube! Thank you guys for the suggestion.

The L-19 p/n 0611064 fit snuggly on my gear leg. The screw holes and outer circumference match the landing gear fillet cover plate. It's .074" thick. My guess is that it is identical to landing gear fillet seal, C-170 p/n 0511125. Unfortunately, at roughly 3.25", it's wider than than the 3" baffle seal material at Aircraft Spruce.

But the baffle seal is sold in rolls....of differing lengths... and a seal might be cut lengthwise...??

You can buy sheet rubber from Grainger, different thicknesses, types, and softness.

McMaster-Carr and even Aircraft Spruce also sell rubber sheet.

Yeah Gene,
There are a lot of options for making those seals if they are all sold out at the link I provided. Being an inveterate cheapskate I was just disappointed that the fillet seal is about a quarter inch too wide to use two feet of the three inch baffle seal. For both seals p/n 05-00811-3 from Aircraft Spruce would have run less than $5.00 + s/h.

Gary, I can send you some rubber sheet from a bunch of old inner tubes we have lying around here.

[n2582d]

Gene,
How much do you think shipping will come to?

If you split the difference on both sides by 1/8” I don’t think you would ever tell the difference in how that 3” baffle seal would work vs the 3-1/4” L-19 seal.

[n2582d]

I’m all set with the L-19 seals. I was surprised that for an NOS part - probably from the ‘60s - it was still supple/stretchy. I originally bought it to use as a pattern.

Does anyone know if the gear leg seal P/N 0611064 for an L-19 Bird Dog can be used to replace P/N 0511125 gear leg seal for our 170's?

The L-19 gear leg is slightly larger, so it may not seal as well as the 0511125 (but you can make your own out of ordinary nitrile sheet gasket material.)

Any idea if the L-19 fillet plate, P/N 0611063, holes match a B-Model? I've asked this question more than once lately, but I'm also searching out replacement landing gear fillet plates.

Thanks all. Good to be active in the forum again.
