Next obstacle to flying - Fuel Strainer

[philnino]

I'm looking at BeeMans pics of his strainer and wondering how the secondary screen actually attaches. Mine is glued on though it does not look original. I don't see it even listed in my 170A parts catalog. It is shown in the 100 series manual.

The screen slips on the pipe which has a slit in it. A spring clip on the bottom of the screen slides into the slit holding it all together.

Does anyone have pics of this spring clip on the gascolator screen? Or a part number? Does this clip keep both screens up on the center post?
Thanks,
Phillip
PS Sorry for the hijack.

It's merely a straight-wire made of spring steel attached to the lower screen-can.
If yours is missing... perhaps a common safety-pin clip might work.

[philnino]

Thanks for the quick reply!
Last question, I promise on this hijack... So what holds the screens in place? I am not at the hangar now but from what I remember the two screens were glued to the upper seal. When I started tinkering I found that the screens would not stay in place on the down tube once I removed all the glue and the old seal. Does the down tube knurling need to be refinished or am I just completely forgetting something?
I will have to see about the safety pin replacement. Thanks for the idea.

I wasn't suggesting an actual safety-pin (althought that might work just fine) but was suggesting that "type" of clip which is available at most hardware stores and McMaster-Carr.

Here's a "hairpin cotter" which is probably ideal in the right size:

The round-middle will circumvent the tube while the straight side will engage the slot in the tube.

Here's a "bowtie cotter" if you can't find the hairpin you prefer ...

I have been going over some of the stuff I missed earlier this year and this particular one caught my eye.
Three pages of hand wringing about a gascolator that can't seem to be replaced by a part number.
What in the hell is such a big deal. I replaced the glass bowl gascolator years ago with a metal one and no one ever gave a damn one way or the other. The metal one out of a later moden Cessna did the job so what was the difference?
I'd consider that about as important as painting the cowling red instead of orange.

Do you have a '48, or an A/B model?

What is such a big deal? Parts approval. I want things done legally/correctly now so that when I eventually try to sell my plane, I am not having to deal with it later.

The problem I had was that the metal gascolator is only approved for the As and Bs....not for the '48 which used a different gascolator. We tried to get a Field Approval to install the metal gascolator that is approved for the 140 (the 140 and '48 170 used the same part), but that was taking so bloody long that I finally gave up and installed the correct salvage part that I bought from someone at the 140 Association board.

I think I have the exact one you need, nos for early 170, I will PM you.

I am certainly no fan of our FAA, but I find it difficult to believe that they would be that critical over a gascolator on an antique airplane. Did they actually refuse to accept that change on a 337 with the explanation of the lack of availability of the original sixty year old part for the replacement?
I can not believe that of the maintenance guys working down at the FSDO level.

Part of the problem was that the old DER retired, so it was a new young pup (fresh out of school in Oklahoma) that we were dealiing with who was treating the approval like a procedure for a nuclear reactor. I could have stuck with it and eventually gotten it, I think, but since I was able to find a suitable replacement part, I gave up and put that in. One of these days, if I need to go through this again, I may try again with a different guy.
