Cox .15 Wrenches at 1/2 price :)

Of course... buy 'em while you still can

Bernie,

I see that both wrenches listed are advertized as fitting all Cox .15 Engines.

In my experience this is not the case. The thin walled and thick walled cylinders require a different wrench. So a wrench for a Sportsman will not fit a Special .15

Not trying to be a jerk, just wanted to mention it. Might save you some hassle in the future.

Ron

Ron,

That is a very valid point that we had not considered when getting the wrenches made. However, we seem to have lucked out lol.

Just tried them on the following engines:

Tee Dee 15
Tee Dee 15 Mark II
Sportsman
Olympic
(don't have a TD .15 Special but believe it's the same as the regular TD)

On the following parts:

Glow head
Cylinder
Backplate
Venturi
Retainer nut

For the Mark II cylinder, the 1/2-circle cutout on the long side works great.

However, I am glad you brought this up as we may have blindly walked into a trap And, never, ever, would we be offended if someone pointed out a deficiency, or potential deficiency, on any of our products.

It may be it's just the Special .15 then.

I have a Sportsman, Special and a Special MKII and I have to use a different wrench on the Sportsman cylinder as the Special one was too large.

Like you, I use the side cutout on the MKII, actually I think it's the only one you can use.

All the ones you listed have the thin wall cylinder with the exception of the MKII which is a different design.

Ron

So, does that mean it may not fit the "regular Special"? It does fit the Special Mark II but I sold a "Special" to a collector last month before I realized that one was missing in my collection.

I hate it when that happens

Can't say for sure.

I have original Cox wrenches so that is all I have to go off of. The part that doesn't work for me is the cylinder cutouts. The MKII has the same cylinder dimensions externally as the Special .15.

I will be home tomorrow and I can take pictures.

In which case the 1/2 circle cutout used on the MKII should work on the Special?

Ron,

Why don't you go to this link:

https://coxengines.ca/product.php?productid=1125

Add two of the beasts to cart and go through checkout using "telephone ordering" and we shall send you two of them tomorrow for you to try and report back to us?

Bernie,

Sorry for the delay on replying. I was enjoying 24oz of prime rib

Anyway, I'd be glad to check that for you, but I am on the road Monday for SC for a month.

If you can wait that long let me know. Another option is to ship them to Rusty and I can drag the engine with me for faster response.

Ron

Which 15 did you want this wrench checked on? I forget....

Special .15

Looks like you have one in that picture.

Yes it would, however, that would be my last choice as it can easily marr a cylinder as well as slip off. It only has one little tab that grabs the exhaust cutout.

That's a cool looking one with the spray gun carburettor (bottom left). What type is that?

Heavily modified Sportsman 15. Ignition conversion and side port induced. Haven't run it yet. Got it about a year ago.

Ron,

Whatever works

You can grab a couple from our site aprx. a week before your return or you can get Rusty to do this now. Just wanted someone to try them on as many .15 variations as possible so that we can list them correctly.

If you give me a measurement of your cylinder wrench cutout I can confirm tonight and post pictures.

It would save you money.

If you want hands on I can grab a couple from you. Actually I would only need one to test with.

0.53"

but the offer stands. You brought this to our attention and you get two free wrenches

Ok,

I have been travelling, but did take the time to check things out.

I have 2 .15 wrenches, one has no cut out for cylinder removal via exhaust port and the other one does.

I measured and it came in at roughly .53 ( I am Canadian) so would have found metric easier!

Luckily my wife is not so she helped me out...

Anyway, the Special .15 will accept the .53 cutout, but it is a loose fit, my Sportsman with the thin wall will accept it, but the fit is much looser. So much so that I wouldn't even attempt it.

What I did find is my .09 wrenches were a perfect fit at least on the Special, and a touch looser on the sportsman. See the attached pictures.


Special .15 with Cox .15 wrench


Sportsman with same wrench. Very loose fit


Special with .09 wrench


Sportsman with .09 wrench (note the gap) which clearly shows the difference between cylinder thickness.


Test subjects.

Hope this helps! I don't require free wrenches, just glad to provide field info.

Ron

That carb body on the TD looks familiar.

Thanks for the enlightenment Ron. I am 100% metric and struggle with the Imperial system but it eluded me that you were Canadian lol.
