Right, so theoretically...

[northwind]

If my "mate" has the front sprocket nut come loose on his SV, resulting in an epic oil leak, what would he have to do to fix it? Will simply torquing the sprocket bolt back up fix it, or is this one of those deals where one it's started leaking, it won't stop unless you replace the seal?

[rictus01]

think you've had it mate, the seal will now be distorted so need replacing, but give it a try by all means..... sorry I ment your mate ;)

+1 think you may need 2 do the seal :( tho as said give tightning up a go 1st it may work it may not.

[northwind]

Yeah, thought that'd be the case :rolleyes: So... Never had to do one of these before, and the spare engine I stripped was all fubared in this area. Am I right in saying that the spacer behind the sprocket should slip out, and under that is the seal? And that it's externally accessed, ie that this isn't a case splitting job?

PS, say yes or you'll see a grown man cry. Or rather, his mate :lol:

[rictus01]

Can't remember off hand, I'll take a look at the manual tomorrow* see if it jogs the memory Mate.

*on upstairs PC, and I'm not doing all those stairs now.

Cheers Mark.

[northwind]

I was just looking through the service manual, it does look like it's an external job but it's not all that clear. I'm not the best once it gets inside the cases so if you don't mind taking a look that'd be brilliant. Cheers mate!

[rictus01]

No problem mate I'm at that PC in the morning, I did do one of these, but it was 5-6 years ago, and to e honest I've done the same on other bikes so could well get it mixed up, so best I check.

Cheers Mark.

I had the front sprocket come loose and leak about a litre of oil along the A3 in a rather nice cloud of smoke. I cleaned up all the loose oil, replaced the lead washer, tightened the sprocket up to the correct torque and she has been fine since. About 5k miles fine I think...

[punyXpress]

Haynes manual says external job once the odd-shaped retainer plate is removed.
Best of luck!

[Ceri JC]

On a related note, I spoke to my local suzuki dealer about whether or not these washers should be replaced when you put a new front sprocket on and they reckoned that so long as you torqued the bolts up correctly and didn't crush them, they would last for several sprocket changes.

[zadar]

just torque it back.spacer comes off by just pulling it.O-ring is inside spacer.

[Peetee650]

So what happens in my, erm, friend has just found the threaded bit said front sprocket nut is on has some stripped threads?:confused:


Sorry for hijacking your thread!

[zadar]

you need to replace shaft,motor apart.

[Peetee650]

oh, fantastic :hackedoff:

[northwind]

Excellent, cheers folks. There was a big chunk out of the lock washer btw, but I think that's a symptom rather than cause. It takes basically my entire body weight to put 150nm on my biggest wrench so maybe it was a little undertight :D I'll fire it back together and see what happens.

You can just get the front sprocket welded on.

[northwind]

Just so we're clear, his friend is not my friend :D

[Peetee650]

or my friend anymore!:evil:

[Dangerous Dave]

Yeap, new seal for sure Northy.

[Sid Squid]

I've refitted and retorqued about five or six SVs that have done this - haven't needed to replace the seal an any of those thus far.

[rictus01]

As far as I'm aware removing the main sprocket nut, sprocket and the shaft space will enable access to the seal, this can be removed and replaced from that point, remember the seal is side specific with the lip pointing out, the manual says to grease the outside lip and install with a little engine oil when fitting, which does help.

Generally the nut holds the spacer in place and keeps the shaft running true, should this become loose this will not happen leading to the leak, if this is for a very short time then it maybe possible to just clamp it all up and as this has no cost it's worth a try in the first instance, but changing the seal isn't a big job anyway.

Cheers Mark.

[northwind]

Tell you what, I'll let Sid Squid and Dangerous Dave, the alliteration twins, fight over it :D

I've fired it back together... Still leaking a wee bit, but it's pretty trivial, might just sort itself out. But it's good to know the seal is so accessible, my dealership's got one in stock so there's plan b if it keeps up its slug impression, cheers for the advice all. I'm having a wee bit of a :pale: to myself thinking how I went round the 2 left handers immediately before I saw the smoke though, the tyre was plastered... Quite lucky I reckon.

Nothing like a a tyre plastered with oil to make you go :pale: :D

Twice or was it thrice, I had the seal on the output shaft fail o my ZX7R. Then there was the time i didn't screw the oiler filler cap tight on my old SV....You get off bike and just can't believe you hadn't come off with that much oil on the rear tyre :pale: :pale:

Still leaking a wee bit,

You could turn your Scottoiler down a bit while you have this leak / chain oiler?

[northwind]

Heh, that's the plus side, not only is my chain well lubed, my sidestand pivot is no longer stiff \\:D/I think the benefits are probably outweighed by the drawbacks though, on balance :D

[rictus01]

So not claiming it as a money saving mod then, what's the cost of a scottoiler these days ?

:smt044

Cheers Mark.

[yorkie_chris]

Lol if you want that, just aim an engine breather at the chain...

[northwind]

I also have a nicely lubed tyre, which should cut down on wear under braking.

[carsounds_dan]

mines started to drip from that area, thank the lord its a quickish job... how much is a seal? o and pee-tee65... contact local engineering works, get them to run a slightly smaller die down it to put a new thread in, then get a small nut to suit... job jobbed
