I am working on a 68 Thunderbolt and got the opportunity this weekend to rent use of a glass bead cabinet for an hour or two. I took some parts including my headlight ears and blasted them nice and clean. in the bottom of the tube there is what looked to me like a metal washer welded into the tube just at the top of where the spring would ride. when I got the parts home one of them was missing, so I pulled on the other one and it came out. turns out to be a metal washer surrounded by a rubber cover. so I went to the parts book and all I could find are a pair of metal and one rubber washer (parts 35 and 36 in the diagram)

https://www.draganfly.co.uk/index.php/bsa/bsa/category/302-front-forks

a bit of research and best I can figure is there are supposed to be a pair of metal washers sandwiching a rubber washer that go between the top of the spring and the lower fork tree to cushion it somewhat, known as spring abutment washers.

that does not sound like what I found in my fork, so I am asking if anyone knows exactly what is supposed to go in the lower part of the headlignt ear on the 1968 A65 fork tube.

thanks for your help

I would post pics but not sure how to do it yet.

Hi Randy,

Fwiw, the quantity of "47-5064 Steel washer" in the Draganfly list is twice the quantity in the original BSA '68 A65/A50 parts book.

http://stainlessbits.com/link12.html describes 47-5064 as "FORK OIL SEAL RETAINING" and 47-5065 as "FORK OIL SEAL RUBBER OR CORK".

Similar Triumph forks of the period including '68 have:-

. a cork washer between the the underside of the lower yoke and a "Spring abutment" on top of the spring itself;

. a steel washer between the bottom of the spring and the main fork seal.

Hth.

Regards,

Stuart,
thank you for the information, I guess I will be buying a set for both sides and get my forks back together

The ones I’ve seen have the steel ring underneath the rubber washer on the bsa type forks, the spring from memory sits on the lip in the fork seal holder (the internal being quite different to the triumph style fork)
