Hi all,
my apologies, but I am a brand new Ariel owner - purchased a nice, partially restored, 1958 Square Four. Unfortunately, the PO had the frame powder coated and it completely obliterated the frame number. I will not be able to register the bike in my state without the number being evident. All I know about the location is it is somewhere under the seat. Since I do not wish to blindly sand off parts of the frame looking for the number, I wonder if someone could please give me the precise location of the frame number on a plunger frame. Is it on the horizontal member, downtube, upper part, right side etc.?

Also, I have the owner's manual and the parts book, but there is a dearth of good diagrams, especially of the cycle parts - is there the equivalent of a Hayne's manual out there?
Thanks in advance,
Paul.

I have '53 and '56 mk2 sq 4 frames. The frame # for the '53 is stamped on the top rt side of the large lug below the seat. There is another number stamped on the bottom of this lug but that is something else. On the '56 frame the frame # is stamped on the steeringhead lug on the right side adjacent to the side car mount. Ariel seems to have been obsessed with inventory control so lugs have a number of different #'s stamped into them. You need to know the prefix of the # you are looking for. I believe your frame should be like my '56 frame. The Ariel parts books really suck when compared to BSA, Triumph and Velocette books I'm familiar with. Lots of parts are not illustrated. I refer to photos in the book "Ariel, the post war models" and look at friends bikes when I need a go-by.

good luck

Many thanks, Larry, I’ll keep looking. I found evidence of a number on the horizontal (uppermost) portion of the large lug under the seat, but that’s not long enough and I cannot see having to remove the seat to look at your frame number. There is also a flat portion on the right side of the lug immediately below (connected to the rear “horizontal” tube that goes back to rear plunger - might this contain the elusive number. Otherwise, i’ll Need to start removing the paint on the front down tube.
Paul.

Paul,
Before you remove paint, try rubbing the suspected areas with chalk, it may reveal the numbers.

Thank you, Ed. Did just that with talcum powder - and found the number! On the right side down tube below the steering head, as suggested by Larry. I'll now try polishing it just enough to make th number more visible - and arm myself with talc when I go to the DMV.
Cheers all.
