TR4/4A 4A Overflow Bottle Bracket

[CinneaghTR]

I have some follow up questions from the radiator duct hardware inquiry I had. Thanks to the guys that helped me with that.

What type of hardware holds the overflow bottle bracket to the fender well? I have two screws, the pointy kind, just driven into the sheet metal. I did not find a number or illustration of the actual hardware spec in the SPC.

I am also painting the bracket body color, but am thinking it should be black.

Thanks for humoring my picky questions!

Sorry Jeremy. No help from this corner. Mine isn't like the one in the SPC - never realized I had an incorrect one.

Here is a photo from the net that I kept as reference

Jay, mine is a repro that doesn't match the SPC, either. Oh well, I passed on two 4A parts cars last summer because they did not have overdrives. I bet they had the overflow bottle bracket!!

 

[CinneaghTR]

Thanks, PeterK. That confirmed my thought it would be black.

Jeremy,

I checked my cars and it should be an L-bracket with a relatively large hole in the lower part of the bracket. That lower part should be mounted under the radiator bracket and the bolt that fastens down the radiator also holds the overflow bottle bracket as well. That's why there is no additional hardware listed in the SPC.

Note that is based on my untouched car. The car I restored has the same bracket but looks like I chose to install it under the nut that holds down the front body mount point. I'd bet my untouched car is correct and I just didn't catch that when I restored the original one.

Note that TRF has this bracket listed (142804) for $14.95.

This overflow bottle for the TR4 was also used for the washer liquid for the windscreens on some TR3As. My 1958 TR3A came new with a "dealer=installed" "Trafalgar" bottle (moulded into the side of the white plastic bottle). The bracket is held to the inner fender (in my case) with two sheet-metal screws amd there is a large "L" where the bottle sits on the bottom horizontal bit of the "L". Then a "belly" band goes all around the bottle about half way up and is clamped togeter with a 10-32 UNF screw and nut.

Hmmmm, I have the wrong bracket and mounting location? This time the "D" in "DPO" does not stand for "Dear."

Dang.

No you've got it right but Don posted a photo of his TR3A washer bottle which is altogether different from a TR4A overflow.

btw- My Trafalger windscreen reservoir is also a completely different size and top opening than the TR4A radiator overflow. But Don's does indeed look like my TR4A overflow used as for washer fluid.

Not to hijack this thread but does anyone have a radiator overflow bottle rigged up on their TR3? If so, where was it mounted? Thanks

My 'project' TR3 had one, mounted to the LH inner wing. Cheesy aftermarket thing, it promptly went in the trash.

Next time I have the front apron off, though, I think I'll mount one from a later Triumph in a more-or-less inaccessible (and invisible) location next to the radiator.

Although, given how much trouble I've had with the TR3 filler extension cracking where it meets the upper tank, it would probably be smarter to just eliminate it and go to a pressurized reservoir ala early Vitesse/Sports 6

Peter,

I believe Jeremy does have the wrong mounting location for his as he he said his was mounted with 2 sheet metal screws into the sheet metal.

Of course we need pictures....

I'm not a source for the 'correct' install but FWIW I did hang the original style TR4A bottle on my TR4 using and existing bolt (possibly the one for the rear of the p/s overrider brace).

Looks like I made a little spacer block out of 1x2 MDF painted black to keep it tidy. Looking at that photo... maybe I used a longer bolt than original and used the existing hole & nut.

Must be close to the correct spot (aren't too many places to put it) and it works great (using original cap)

I never did on eon the TR3 as the original cap (IIRC) doesn't work w/o modification... plus it has that expansion tank built nto the neck. On the late TR4 with no neck and no overflow the coolant level can be pretty far down from the rad neck in a cool condition.

Here's a picture of just the mounting bracket (I pulled the bottle out) and where it's mounted on my untouched car. On the one I restored, I mounted it under the nut to the right for some reason.

Thanks again, Scott. My bracket is not mounted there. This is what I am thinking: I have the TRF bracket listed for the 4-6 range. That 14... number Scott mentioned earlier does come up, but it does not in the cooling special catalog.

I just ordered the Moss, which does have separate part #s for both brackets, and will see what I get.


I'll update you guys with pictures after the weekend so stay tuned.

This is Moss #850-400

Jeremy,

Looks like TRF made a mistake in the cooling system special catalog. If you search the parts database for the 713544 it only shows being applicable to the TR5-TR250-TR6.

Here's the description from the parts database for 713544.

Got the Moss bracket today. Made in UK and the right one. I'll still update with photos soon...

 

[CinneaghTR]

I threw the TR6 bracket into the powder coating order and it came out like this:

 

[CinneaghTR]

I will be going with this until I can get the right bracket coated and installed. More holes to plug up...
