New T/C Filter UPDATED

Thu Apr 18, 2013 6:59 am

Was having trouble in my 1949's T/C unit, so thought an overhaul was in order. Opened up the unit and found some bad o-rings, but also an old, brittle, cracked fluid filter. After looking how it went together, I got the propane torch out and released the two steel rings at each end.

Image

Then I cleaned up the rings and cut a piece of bronze wire mesh (same stuff I've used to make gasoline filters in my sediment bowls).

Image

Image

There's about a 1/4" to 3/8" overlap in the mesh. The steel rings were reapplied, holding the ends of the mesh, but I needed a wire loosely wrapped around the center portion to keep in in place while soldering.

Image

I used a propane torch at first with acid flux core solder:

Image

But then switched to a Weller soldering gun with a flat soldering tip. The propane torch was too hot making the solder blotchy. The Weller flat tip was a big help smoothing it out.

Image

Image

Then installed.

Image

The filter was about 1/32" too long, so it bent up the mesh a little to get it in, but think it an improvement over the previous one. :wink:

EDIT ADDED: Wire reinforcing mesh.
Added some galvanized hardware cloth (1/4" squares). Wire wheeled it down to just slightly shorter than the filter's overall length (6-7/16").

Image

Then, wrapped it, rolled it and soldered it in place.

Image

Image

Image

Finished result.

Image

Can you tell which part has been repaired? :lol:

Fired it up and it works just fine (forgot to paint my hydraulic lines and pump,oops).

Here's where I bought the brass wire mesh: http://www.animadesigns-shop.com/Brass- ... p_747.html

Again, I saw a lady use it on craft projects and thought it to be the same wire count as the fuel bowl strainers (which it is close). So I ordered a roll (12"x36" for $10 + S/H). Thought the price was reasonable.
