4G shock aborber 1272-37

The sliding member on my 4G engine shock absorber (1272-37) has broken. The shock absorber looks much flimsier than the later type -is this failure a known problem with these? Also can anybody suggest a source for a replacement?

Re: Front Brake Cable Nipples

Nev I agree the steel nipple looks pretty robust. Any idea where I can get these steel nipples (and crimping tool)? I think I have seen crimped nipples used on car and trailer handbrake cables however these are on much heavier cables - the Ariel one is a No.2 cable. All the aftermarket motorcycle br...

Re: Front Brake Cable Nipples

Dave I looked at using a pear shape back to front but unfortunately that relies on making the spherical shape in solder and, since this rotates in the brake arm it will probably not last long plus you then can't splay out the end of the inner when soldering the nipple. I am sure someone somewhere ma...

The brake arm cup seems to be about 8mm (5/16" in old money). I have only found ball nipple sizes of 4.5, 6 (used on valve lifters) and 11mm (old 7/16" - used on trailer brakes) but I am sure someone must make 8mm.

Re: Front Brake Cable Nipples

Dave I've tried a standard pear shape however the problem is that the cup in the brake lever is spherical and the slot is only wide enough for the cable inner to pass though (not wide enough for the neck of a pear shape). The arrangement seems to be designed so that the ball nipple can rotate in the...

Front Brake Cable Nipples

Does anybody know where I can source nipples to use on a front brake cable for a tele fork half width hub? I've tried a 6mm ball (from a valve lifter cable) but it's too small - the cup in the brake arm is about 8mm.

BA Gearbox Questions

Having finally managed to extract the gear cluster: 1) I have found a broken spline on the layshaft (inside the 3rd gear). Is this a fatal flaw or can I still run this layshaft with reduced number of splines? 2) The layshaft clutch seems quite rounded. Do I need to find a replacement for it? 3) Ther...

Re: Stubborn BA gearbox nut

Thanks for all the replies. I had already tried an air spanner with no effect and after a further day of grunting and swearing with a long arm socket I gave up and resorted to Nev's suggestion and cut off the nut. The nut easily separated into two halves with a splitter however one half of the nut s...

Re: Stubborn BA gearbox nut

There is a short section of thread clear of the nut I am pretty certain it's RH (looks like 7/16" 26tpi to me). I'll give it another go tomorrow.
