Sturmey Archer TCW *??????*

The Sturmey Archer TCW on the '62 Raliegh Sport I just took
possession of skips second gear. As in -nothing there-. The shift
lever can be moved to first and second but the hub says first ! It pops
into third with no problem. When I disconnect the cable and try to work
it by hand I get a false nuetral for second.
Ive adjusted the chain and cable according to Sheldons site and determined
it must be an internal problem after too much time spent trying to adjust
it and count wheel/crank spins. Ive take the hub apart and can see how
it works (sort of ) but I cant determine what might be making give
a total neutral spin in the second gear position. Any suggestions ? Pawl ?
I can see it might have not had an easy life
Thanks in advance !!

Lem,

Try this link for Sturmey Archer repairs and adjustments. The guy seems to have about all of the covered. And here is another one it is for the SW hub but a lot of the basic information is the same.

sometimes the cable has to be looser than it would seem, particularly on the older engraved triggers. if that fails and you have access to a newer coaster or normal three-speed, i'd do that before trying an overhaul. TCWs are not known for their stopping power.

I just added a rear hand brake to my wifes "new" Raleigh Colt with the S3C hub...I was test riding it and broke the front brake cable, the coaster is not a brake it is a speed *********** device good thing there were bushes at the bottom of the hill BTW here is another good S-A link These hubs are amazing...now I am thinking about building a 3 spd tandem...if I can find a decent 63/43cm frame...

All of this is not making me optimistic about building a wheel around a TCW Mk.III I have lying around the shop...
I've found the "speed ***********" feature to be true with Sturmey drum brakes as well.

While we are on it, I've also found the "speed ***********" feature to be true with Raleigh Sports hand brakes as well (that is if it isn't raining - then it is a "delayed speed ***********").

Most three-speed hubs are not up to the potential axle loading or torque of tandem use. Yes, I know Electra builds three speed tandems today, and back in the old days Sturmey did offer tandem rated hubs, but AFAIK these days the only similar IGH that's blessed by the manufacturer for use on a tandem is SRAM's P5 Cargo (and only the special Cargo model, not the regular P5).

It might work fine for you, I'm just sayin'.

That would be the first thing I'd look at. Sticking (clean and lube), broken spring (repair).

I would say its the pawls
little diamond shaped things at either end of a normal SA hub
dont know where they are on youy hub
they go rusty
and the tiny springs break up
clean them up
might need new springs

I put a seven speed Sturmey-Archer Hub with coaster brake on an old Columbia Twosome tandem and haven't had a problem yet. It's probably gone only 200 miles with me and a child peddling, so I'd describe it as having extremely light use so far. I do feel it has a certain hot-rod character though, and was worth the effort and minimal expense.

The screeching mentioned above sounds like the coaster brake needs greasing badly.

A number of very knowledgeable SA folks available at he below link. This is a specialty Yahoo group with members interested in all gear hubs from all manufacturers.
