Serious Gearbox problem :(

right guys serious probs with gearbox ,

went to ride today and she goes into first second but no further, when its in 2nd gear the lever goes up but nothings happening,

i can back and adusted the lever etc and tested again and nothing still.

so i think theres a internal problem with the gearbox but what could the problem be??

please help

thanks guys

Phil

p.s. shes a sv650s 2006

Bent selector rod? never seen the inside of an SV gearbox.. reckon somethings bent or seized though..

so i guess taking the side cover of and removing the shaft for inspections

hmmm

would i need to drain the coolant and obversely the oil??

help...

if you want to take the engine apart get a haynes manual and the correct tools, it'll tell you everything you need to know

i'll be honest though, i'd feel fairly confident taking the SV down to it's component parts, but reassembling the gearbox is about the only thing i wouldn't want to attempt on my own...

Right start with the simple stuff like is the lever moving freely? Will it select gears at a standstill (you have to rock the bike about a bit to get them to engage/disengage)

I would guess that the end of the selector shaft being hit has damaged the external shift mechanism, i.e shift star, detent arm and spring etc Sounds plausible that the shift mechanism is damaged as it won't shift through "third"

You need to take the RHScover off to get to this, I'd drain the coolant, but you can lay the bike on it's side a little more and not have to drain the oil.

If there is no damage to the detent mechanism then it's total engine strip time

Isn't as scary as it looks, but requires care.

yep, tbh the box is the only part of the bike where i can't visualise how it's assembled, which puts me off taking it apart

Replaced them before and I can summarise it in brief.

There's lots of cogs and forks n stuff

ok guys thanks alot

ill go and take the cover of now, and see whats damaged thingers crossed its the shift shaft etc

do i need to take the clutch assembly off first to gain access to it?
