Brake Plate - Extra Hole?

Three identical brake plates, believed to be P/N 4467-51, but the plate in the center has an extra hole drilled in it. The brake plate came to me without any of the other brake parts. Unless someone knows the plate with the extra hole in it is for a specific model, my guess is someone drilled this o...

Re: Rods and generator

Thank you Paul, do you mind passing on details of where you ordered the rods? I checked with the usual suppliers and was told it would be "the end of the year" before any would be available. Thanks also for the info on the L/E size. This is my first Ariel rebuild so I haven't got the insi...

They are about 1/4" long, csk screws.


Thanks Simon.

I have the originals somewhere...I know I placed them in a zip-loc bag and put the bags in a safe place as to not lose them...such a safe place I can't find them now.

SQ4 Sludge Trap - threadform and size?

Does anyone know off-hand the threadform and size of the sludge trap screws used on the SQ4? Part number 1190-37.

I need 8 of these screws, Draganfly is on back order, but believe I may be able to source the correct screws from a hardware specialist here in the USA.

Thanks for your help.

Re: Rods and generator

The manufacturer of the new rods states the big end size as 1.4999 - 1.5004.

Manufacturer quoted me 4 weeks to produce the rods; my order is supposed to arrive next week, making the total lead time 3 weeks.

Re: Club Rods are tight

What should the dimension of the big end be without a bearing shell?

I'm having two sets (8 rods) made by the manufacturer and it sounds like the blueprints they have show two different sizes for the big end.

Re: Its Finished .

Very nice Guy! Any chance you could share some detailed photos on how you mounted the Rodark panniers? Did you make the mounts or use a mount that was commercially available in the past?

Thanks.

'51 SQ4 - Reproduction Fuel Tank

Before I start cutting and welding, I'm hoping I can get a second opinion or any advice from members with previous experience fitting an aftermarket tank. I just received a reproduction tank from Draganfly for a '51 SQ4. The significant problem is that when the tank is as far forward as it can go, t...
