I could cry... SV gearbox damage.

[lilredmachine]

I've had the SV for about a month, and some prick has already decided to jump up and down on the gear lever so hard that it has bent the lever down towards the floor, broken something in the gearbox (possibly the selector fork) so that the motor is jammed and won't turn over (the bike is 'stuck' in neutral so can be wheeled around) apart from every now and then when the input shaft from the lever mechanism is wiggled, and then only with a nasty metallic grating sound. What is it likely to have fubared in the gear box, and is it an engine out job to get at?

This happened at college. Some little shit is going to pay.

Oil out, drain coolant, right hand side engine casing off, remove clutch plates and holding thingymajiggy. If you can do that, you should be able to see if there is any damage done to the selectors and what not.

Do it, do it now. Before I forget what the insides of an sv engine look like.

did you give the person a go on your bike? or was this done delibratly?

No, it was parked up in college and some little chav shit has done it. I fired it up and went to leave, tapped it down into gear (hadn't looked at the lever) and there was a nasty metallic noise and it locked at which point i nearly dropped it, that was it. I've got the college to check for anything on the CCTV. God save whoever has done this, if i find out who they are.

[instigator]

If they do have the culprit on cctv, try your best to get a copy and take revenge that way. Police will do sweet bugger all. I'm not overly sure WHAT it could be but I do know what the insides should look like. Would be interested to see what the left hand side rear seat looks like too, to see what has been bent/snapped.

Should you need any parts, I've got both a spare engine in parts and a whole spare engine.
However, I've seen some SV engines go /very/ cheaply these days, so could be worth a look on ebay and motoforum - talking £100 for a complete working engine!

[lilredmachine]

Thanks for that G, i'll bear that in mind. I'm hoping that it won't be too bad when I open it up, but it does not sound good at all. Should the worst come to the worst at least a new motor shouldn't be too bad to get hold of

In order to remain on two wheels, I've dusted off the DR for a while. To be frank, it felt so good to ride it again, I may just fix the SV then flog it!

Ouch; rectifier on my road SV went and it was about £25 all in on ebay - though I did nick one from the race bike while I was waiting for it .

That's some shocking luck, especially since you only just picked up the bike. Unfortunately I doubt I could be any help; I haven't really got any spares about and haven't gone anywhere near the gearbox on my SV.

I've got it back home, I'll crack her open tomorrow. Found the motor manual so i'll be armed with literature. I'll take pics for the more familiar-with-sv650s members for seeing if there is anything obviously out of place.

Ok, it's been knocked back till tomorrow. Got a day to do it then.

Just one thing, why do I have to drain the coolant? Sounds like a noob question I know, but I didn't have to on the MZ to do essentially the same thing...

If you're taking the right side panel off (which I presume you are), the coolant pump is located there. This includes pipes that go into the engine, so when you take it off it will break the seals that go to the pump and dump the coolant (usually half of it into the oil if you haven't drained it).

that's crap luck mate. hope you find the scum bag that did it.

[lilredmachine]

No, not yet. The college hasn't gotten back to me on whether or not anything is visible on cctv.

[G]

Not sure if I'll be as much of a help as you're hoping.

I expect it will be quite a big job to get to them. Not as tightly packed as some sports bikes, but then they usually have a removable sump.

[lilredmachine]

Any suggestion on how to remove the clutch basket? It's 'stuck' in neutral so there is no way of stopping it from moving as the hub nut is turned...

Screw driver jammed inbetween the two sets of teeth so it gets difficult for it to revolve....?

I was lucky, on my sv, once I had undone the crumple washer, the nut was literally finger tight. But on my diversion, I was jumping on the torque wrench and it wouldn't come undone. Some are 5nm tight, some 150nm.

There is a special tool you can use in such circumstances but I am not sure how much it is or where you'd get one. Sick'up probably knows I imagine.

[G]

Air/electric impact wrench is the best way.

Otherwise, haynes usually shows a way to make a 'holder' out of two strips of metal - you bend the end of each one and join them in the middle to make a scissor/plier style device; then poke the ends into bits of the clutch basket.
I tried making that once and failed, so took it to a local garage instead.

[lilredmachine]

Just chiseled the nut off in the end. Not like it's going back on the road soon anyway

The problem has become rather... terminal. There is now a feck off hole in the crankcase. The damage is so severe it is difficult to tell what has gone on inside. My best guess is the abuse the gearshift mechanism got made it fall apart in the crank case, the actual shifter was wedged between the primary drive gear and the oil pump drive and is bent to buggery. The main damage was probably done when the shifter wedged in the main drive when it was running, the jolt it put through the mounting in the crank case broke it off, and all the little bits of crankcase then went through the motor resulting in the nasty metally/oily mess that came out when I took out the sump plug.

Short term prognosis is it's fucked, I need a new right hand crankcase (at the least, not to mention the gearshift mechanism and possibly the oil pump drive gear and primary drive gear) and it's an engine out job. One side of my head reckons it would be an easier and in the long run cheaper method to try and obtain a second motor and swap it in, keeping this one as spares. The top end is fine. Unless anyone has a right hand crank case going cheap?

This is quite possibly the worst thing that could of happened
