Rear Axle

[Jeffrey]

Evening Folks,

Could someone please identify this axle for me, I cannot seem to find anything that resembles it? I have been through the online British site etc and even searched parts traders with part numbers but nothing seems to look anything like it.
I have also supplied a pic of the bottom right fork slider with the outer cable bracket thingy not sure what you call it, what year was this introduced.

Thanks for the support.

Cheers Jeff.

Well Jeff, you may get some answers if you add make , model and year….otherwise it’s just a guessing game.

I haven't a clue, but I agree. How did you get it or where did it come from? Do you know anything about its history?

 

[Koko3052]

I’m thing that he should know as I see that he has the front end in his possession…..presumably he has the whole bike.

Certainly the OP should have an idea of what they bought. Hopefully they will respond back with the details, otherwise this thread is going nowhere.

While an o.p. starting every thread with "make , model and year" is ideal, if you click on "Search" at the top right of the webpage, then "Advanced Search", then start entering "Jeffrey" in the box to the right of "Posted by:" then click on "SEARCH", the Forum will return a list of links to all of @Jeffrey's posts, latest first ... His two threads immediately previous to this one mentions a 64 Triumph 650.

identify this axle
bottom right fork slider with the outer cable bracket thingy not sure what you call it

If your photos are from parts on your 64 650, neither is standard, I am not sure if the axle is even post war Triumph?

If the forks are Triumph, ime the usual term used for the "outer cable bracket thingy" is "Abutment".

You might need to try a site like IKBA (start entering "ikba motorcycle" in your browser search), the contributors are mostly old but have experience of a wide range of motorcycles, including from countries outside the UK.

Just out of curiosity, what are the various diameters on the spindle, what are the thread tpi (turns per inch)?

Sorry Guy's

I've overlooked that completely make and year.
The forks in question were in a duplex frame early 60's. I have worked out that the bottom yoke has had the steering stops cut off at some stage not sure why, but maybe to get them working in that frame . It was also running the TLS break but I have gone back to a 8" SLS in Boranni 19" front with 37-1239 spindle, to me it's more period. I have since installed the forks back into a 1955 single tube frame.
I then removed the rear swing from the duplex and installed it in the frame as well and it appears from what I can see, will work fine. Installed new 6204 bearings in hub W-1158 on 19" Boranni. From here after going over the British Tech site and looking at pics of rear axles from parts suppliers nothing comes anywhere close to the one I removed. I'm starting to think this could of been machined up for whatever reason. The bike has history of being owned by a NSW Australian bike racer.
I was curious and posted the picture just in case I was not researching well enough. But it may seem that the rear axle has been machined up?

Anyway sorry for not detailing the make model.

Cheers

Sorry Rudie,

I will get back to you with those measurements.

Cheers.

The forks in question were in a duplex frame early 60's. I have worked out that the bottom yoke has had the steering stops cut off at some stage

Afaict, Triumph bottom fork yokes did not have steering stops until the unit 650? Then additional metal was cast on the back edge of the bottom yoke to bear on studs below the frame bottom steering bearing housing. Then, bottom yokes intended for US market models with small tanks, the additional metal was ground off during casting machining.

According to the 61 650 parts book, duplex frame steering stops appear to be two bolts in the frame? As the parts book also shows locknuts, guess says the bottom yoke back edge bumped against a bolt head on full lock either side, the bolts were adjusted so the bottom yoke hit them before the nacelle hit the tank, the bolts were kept in position by the locknuts?

installed the forks back into a 1955 single tube frame

All unit 350/500 models had a single downtube frame, pre 67 steering stops are special nuts with long studs on the bottom yoke stanchion pinch bolts, part number 97-1335:-

... end of the stud hits the frame downtube on full lock.

rear axle has been machined up?

The axle in your photo appears to have been hard chromed? If yes, ott for a home brew?

Reiterating my suggestion posted earlier, I believe you should ask more widely, the axle could simply be from another make of bike?

was also running the TLS break but I have gone back to a 8" SLS
more period.

So far, does not read like you are building a show bike? In which case you will be riding it amongst 21st century vehicles with disc brakes on all wheels? Your bike and SLS front brake will not look very "period" jammed into the rear bumper of a 21st century vehicle that stopped quicker than your bike's SLS? Ime, owners of old Triumphs do not fit the late 1960's TLS just to be contrary ...

In all my days, I've never seen an axle like that one.

 

[sikatri]

Looks like a few parts are missing. How is the axel held in place?

 

[Jeffrey]

It does have outside nuts and chain adjusters etc.
These as well from what research I've done they could be from a trident?

 

[Jeffrey]

I've since purchased a 37-1025 from overseas as Oz is bone dry at the moment.
Not convinced that this original set up is ok.
Thanks Jeff

 

[sikatri]

You lost me. Was the OP about a front fork or the rear? If it’s the front I’m still not sure how it all goes together with the parts shown.

 

[Rudie]

could be from a trident?

Definitely not. If the axle was from a Trident, I would have posted that weeks ago. If you look in the 1971 T150 parts book, you will see the rear axle is nothing like the one you pictured in your first post.

Those parts, or very similar, were used by Harley Davidson years ago and they do their job very well in keeping the chain tension and tracking as it should be.
