How to get the axle out??

[Nvreloader]

Hey guys
This is a drawing of my rear hub, I need to get the axle out for measurements, so I can get the correct Robert axle for my trailer installment, the OEM axle is a QR type 190mm in length.
I am attempting to figure out HOW.??????
Any suggestions would be greatly appreciated,
Tia

does it have the usual quick release or a through axle? Kinda looks like a through axle so thats usually 12mm or 15mm. a pic would help.

Here is a photo of the rear hub, (Top Hub) 5mm QR type 190mm in length. I have not found any threads, hidden keys, set screws etc, used for removal for the center axle.

I don’t understand why you would need the inner axel length but…

The end caps are pressed on, not hard to get off but easily damaged without the correct tool.

the free hub likely unscrews once the cap is out. ( some just slip off with the cap)

if you have a depth gauge the inner axel length can then be worked out, otherwise start driving bearings out.

Have you tried just tugging on the caps / adapters? Looks like it's set up for a 12mm thru axle with a 5mm skewer adapter. I have a similar set of hubs. The caps just slide off.

Thanks Guys
I'll try carefully getting the end caps off,
there is a small tip of the axle showing and it measures 10mm dia,
but looks to step up to a larger unk dia at the start of the end caps.

I need the spec's on this axel,
so I order/change over to the correct length/diameter,
solid axel to add the bobbin ends to this axle for attaching the trailer,
as they don't make a skewer with the bobbins ends, that is around 220mm long,
the OEM Skewer/Bobbin ends is 190mm long and is too short.

The OEM QR Skewer length is 190mm long and I have to have a 220+mm long solid axle for safe/secure trailer attachment, for attachment of my single rear wheel trailer.

Thanks guys........back to the rear axle........

If the end caps are press in sheet metal cups:
replace the tightener and dummy nut with real hex nuts. Cover the threads.
Set one end on a deep socket large enough to support the hub but not the cap. Use a bearing press, or beat on the top nut with a hammer.
To re-insert the caps: find a socket that just covers the cap but not the hub. Support the other end of the hub with the socket that supports the hub rim. Press with a bearing press, or use a hammer straight down. Do not get the cap with only one side inserted. It might bend it.

I'm not really sure what your plans are, but I looked into a rear rack for my hub bike that uses the same sort of bobbin ends as what your using.

The bobbin ends can't be attached to my hub motor because the motor cable runs through the middle of the axle.


I recently bought a trailer hitch that attaches to the chainstay so I can attach a trailer,..

They also have this version for a trailer hitch attachment,..

You might be able to mount one on each side of the frame and attach your bobbins to them?

And it would help move some of the trailer weight forward to get your front wheel holding more of the weight.
