Air steel Shaft Drive for Hyosung GV650
« on: November 20, 2017, 11:56:47 AM »

Hi All,
I'm from Ukraine and working at Hyosung Ukraine company.
On our market  we have a lot of GV 650 and most of them have problems with drive shafts.
The main problem is that shaft very very low quality. On the European market every year we have problems with shaft supply.

Our company do not want  wait improoving quality from hyosung and decided to make new very high quality shaft.

Maybe somebody know that in Ukraine (Kyiv) located huge air craft company Antonov.  They make good planes  AN. 
Antonov company make for us this shafts from air steel and now we have very high quality products.

please see specifications:
Type of steel 12HN3A:
- 3415 (USA analog)
- 1.5732, 12Ni14, 14NiCr10, 14NiCr14 (Germany analog)

- improoved shaft spline, more push fit of sprocket (pulley)
- post-fabrication heat treatment

if anybody interesting of it please write me PM

whole gearbox could be a problem because we need to order at least 20-30 units. it will be huge money.

maybe a little later we will try to make just 2nd gear and 6 gear.  this gears as usual die first.

I do not agree that the GV has bad quality drive shaft, rather bad mechanics that not know how to torque the and lock the nut. And, no offense, but i own a couple of USSR made bikes and it is well known Ukranian made parts are pure crap. I sure hope this is better.....

Koreans knew about problem with shafts on GV.  couple years ago they changed construction of pulley. They made it a little wider. because with old type pulley  shaft die too quick. at this moment I know about  20-25 aquila GV with this problem and it's only at Ukrainian market.

Metal analysis showed that OEM shaft made from low quality steel. It's too soft.
How do you think could quality part cost 19 EUR ?   Yes yes 19 EUR this is shaft price for dealers.

what about USSR quality. evetything made by USSR - junk. I'm very happy that this union is died.
but what about Ukraine I'm not agree.  Yes, in some products we have junk soviet quality  but also we have a very good products. one of them ANTONOV.
That's why we asked Antonov air plane company made this shafts.

Dream of all bikers in USSR was JAWA.   )) It's a very good bike.    
especially - 350 cc

This soviet bikes like URAL, IZH, MINSK, DNEPR   everything was stolen. Soviets did not research anything. Everything stolen from Germany ( BMR  R, DKV ) and copied.

Lads copied Fiat, no? ..an unusual decision. Why not copy a Toyota Corolla?

Lada did make the chassie under licens from Fiat, but made their own engine. They wanted it to start in -40 and be able to use 72 octane fuel.
