We have the owners manual and parts lists for the Beaver, but don't yet have a scan of the service manual available on the forum.

It may also be under "Documents and Manuals" listed under Cox History on the tool bar left side here.

Also a quick look and I could not find the decals, if I still have two, you get one.  Otherwise there is the levent option, but these are not quick and easy to make.

Bob,
THANK You so much for the Owners Manual scans.
I did count 20 pages total downloaded.

Perhaps you can enlighten me on the "Levent" option for decals? I am not familiar.
I would certainly be happy to pay you for one yours, if you can locate one.
Beer Cheers

I will post some photos later of my resto...

Levent is an engineer and master craftsman who lives in Turkey.  He's a frequent poster and a friend.  A couple of years ago he made these Beaver decals and sent them to me.  As I mentioned, not easy as they must be affixed to sticky backed aluminum stock and printed.  Be patient, they will turn up.  But, I'm a bookworm with hundreds of books to go through.

Sadly, here was the result of apply FROG painters tape (ostensibly to protect the decal from paint), then peeling it off.  Believe it or not, this original decal was in REALLY good shape prior to this little DISASTER

The Beaver chainsaw, Cox's most interesting product - Page 3 7fe6a610

Here all the pieces laid out. Some have already been sanded and painted. A work in progress...

The Beaver chainsaw, Cox's most interesting product - Page 3 165dec10

Here are the two paints I tried... The Rustoleum 'Marigold' looked like it would be a good match, based on the color of the cap, but once applied was not very close.
I settled on the Rustoleum Sunburst yellow. It lacks some of the orange tone of the original Cox paint, but since I planned to completely paint all parts, who will know (but me and you)?

The Beaver chainsaw, Cox's most interesting product - Page 3 69c06e12

I tried to remove the Flywheel to free the engine and ignition from the last remaining bodywork, but NO DICE. I have two pullers, neither of which would work and the "pry with two large screwdrivers" technique didn't work either. I elected to simply protect everything I didn't want painted, and go for it. All painted parts were first lightly sanded with 220 wet, then cleaned with lacquer thinner. Chipped or gouged areas were sanded smooth prior to painting.

Nice job.  I see you have the black chain saw cover, usually they are painted engine body color.

Removing the flywheel is easy.  Just heat the flywheel around the shaft with a heat gun or butane torch, hold it above something soft and with a gloved hand around the flywheel tap the shaft with a hammer.  I have done seven that way.  

Protect the threads with the fixing nut. (Seen second picture)

The good news is, I found the decals and will send you one.  PM me your address.

I got the replacement Kolbo/Korp 20" propeller in today for the modified Cox 140 engine. I'm amazed that they are still available. Maybe there is a market for them on drones etc.. It replaces the broken prop that came with it. I mounted a smaller distressed one on the 140 just for looks.

I may put it on the engine but I'm thinking, mount them both on the wall on either side of the Cessna. Maybe.

Bob, I think that Cox 140 engine with prop, especially with the larger prop made to run with it has a high potential to be a Cox Engine of the Month winner. Very Happy

If you were to mount and show a photo of the prop spinning, I can't see why it wouldn't be a winner. This Site Rocks!

[quote="roddie"]Hi Robert, Amazon stocks 1/8" ID Viton tubing.. and a small sintered-Bronze "Clunk" pick up that should work for servicing your saw's fuel tank.

The Beaver chainsaw, Cox's most interesting product - Page 3 Viton-10

Got the tubing roddie. Pure gold @ $15 + shipped for one foot, and the vendor got it wrong. More like 7/16" OD, 1/4" ID.. Normally I would eat it, but fifteen bucks for the wrong item is more like an evening meal at the Waldorf rather than lunch at Mickey Dees.

The Beaver chainsaw, Cox's most interesting product - Page 3 P1018373


Asked the vendor for a refund, or ship the correct size.

The Beaver chainsaw, Cox's most interesting product - Page 3 Empty Almost done...

Post  BlackWidow Wed Oct 02, 2024 6:14 pm

Well, my Beaver is about as good as it's gonna get, except for the replacement of the round COX decal on the pull-starter side.
As I posted earlier, I taped off the decal in preparation for painting, but when repositioning the tape could see that it had destroyed the decal. Mad
Once the decal is replaced and I have added the "FUEL" and "CHAIN OIL" lettering, it will be ready for my Cox display case (although I haven't yet figured out HOW I will squeeze it in there!)

The Beaver seems eager lol! and I see no reason it shouldn't start... just not sure I want to start to go there, with the associated mess... maybe eventually This Site Rocks!

Beautiful restoration Richard.  Makes me want to paint one of mine.  

Thats the thing, you go to all the trouble of cleaning it up then if you gas and oil it (which makes a mess) and your almost back to square one.  Admire it for awhile then test it out.  

If it has a number stamped on the bottom of the engine, PM me with it, I would like to compare.
