View Full Version : Crankcase plug/cover on the bottom
On the bottom of the bike near the sump bolt there is a 10p (ish) sized cover with a hex slot for an allen key, what's under this cover? If I were to take it off would all the oil drain out as per the sump bolt or is it for something else.
On the fiche, Crankcase (model X/Y) it's number 21, plug 16*8 ???? (I think).
Basically I have an oil leak down there, it's either going to be that or the two lowest bolts holding the crankcase together or possible the gasket between the two half's of the crank case. I'm still looking but was wondering what that cover/plug was for?
thanks - Si
It is just plug to close hole. Oil is behind it.
is it a bolt or a allen key ? which year sv only asking cos i have a new gasket that i ordered by mistake!!
It is bolt with Allen key head :). With copper crush washer under head.

i think thats what i use as the drain hole the drain bolt was like cheese so only oil behind it there was no washer behind mine tho or gasket.
hth
You can't drain all oil there so it should not be used as drain plug.
Thanks for all the input - I'll locate the oil leak and tbh hope it's that plug, if it's not then its the gasket. We are only talking a drip every other night but that's enough to do me in on a corner as it goes to the back wheel from there. If I can't fix it directly then I'll have to get clever and add parts to the belly pan to funnel the oil away from the tyres. Maybe to the engine to burn it off on the cover. mmmm

Check your oil filter, maybe that is where oil is coming from. Clean whole bottom of engine and look for oil.

did you leave your brain at home when you posted that? tilt the bike and more drains out, put bolt back in throw a bit of oil in so some more crappy oil gets collected from lower parts remove bolt again, drain, tilt to finish draining and you get near enough all the oil out. which is good enough for me.
the oil drain has a crush washer which is different from a copper washer you can tell the difference the proper crush washer is flat on one side and humped on the other i think the plug been talked about is the oil galley plug

And did you have to work real hard at it?....just asking

ok, time to see the rabbit so to speak:

A - This is the oil drain bolt
B - This is cover I'm not sure of, so it has oil behind it but what is it's primary purpose in life?
C - Possible cause of the oil leak or maybe a little higher up the crank case, one thing i know it's not the clutch cover o-ring as I fixed that and that's still fine.
So what is B for apart from a spare drain hole?
Anyway, time to clean the bottom of the bike this weekend and break out the talcum powder. :smt023
No comments about the condition of the pipes ;-)

I dont think Zadar deserved that comment - he is the source of top rate information, and should be treated with more respect than that.

You can tilt all day alone but you will not get all oil out. When you see cases from inside you will know why.

There is no oil that can get inside C and leak out of its head unless cases are cracked.
B is just plug to close hole, that is all. Just like couple 12mm bolts to the left and right of oil filter, the ones with crush washers under head, they just plug holes used to machine interior of cases, galleries.
I am pretty sure your leak is coming from side cover or oil filter area. Clean, powder it and you will find it.
Ta m8, powdery photos will follow on the weekend.
Red line shows how high in that bolt goes, you can't drain any oil bellow that line. Left is pointy and right curvy.
Blue line shows why plug is there. They had to drill through cases for oil gallery to feed oil to oil pump. Only way to drill case is all the way through and than plug hole.

Not exactly the oil gallery plug, it isn't under oil pump pressure. The main oil gallery plug is on the side.

Let's be honest you don't sound like the sharpest knife in the drawer insulting someone who unlike yourself has actually cracked a few engines open and has more'n likely forgotten more about SVs than I know.
And you come across as doubly friggin dense when you decide to insult someone who's giving you advice that might actually save you from blowing an engine to bits when you need to get the remnants of a f*cked clutch out of your sump.
Tard. Poster ignored.
And this 4 are your other gallery plug bolts.

Very interesting. I have a question though, it's probably simplistic but, what does the term 'Gallery plug bolts' mean?
Is it as simple as they are bolts that plug holes in the engine casing that are were needed to be drilled for other parts and hence just stop oil falling out?

Yep, that's it. No other way of getting access to drill/machine the galleries than by going through the outside. To then 'plug' these holes in the oil 'gallery' suzuki just put a bolt in. :) Simples.

Well the talc doesn't lie and to complete my week of muppet moments ...
I went out to help my daugter with a brownie badge with a clear blue sky. I return to my unclothed curvy and it's only snowed tonight so snow in the air box and all over everything else.
Anyway, I'll quote myself:
"one thing i know it's not the clutch cover o-ring as I fixed that and that's still fine"

like I say the talc doesn't tell porkies and it's not just one bolt as it was before but half the oring. I know I wanted to try this spanner lark out to see if I could but sometimes it just gets you down. I dread to think what will happen when I try and start the engine again after I've been at it.
