I've struk oil!
« on: 01.10. 2014 17:17 »
Hey guy's,

While removing the primary cover for an oil change, and a new gasket.
I noticed that after draining and removing the cover there was a constant stream of oil
coming from the screw hole where the oil level screw goes... it seems strange to me that there is an direct
connection between the cater and the primary... with all the different oil and such.

So who can enlighten me here?

In the pic is the hole I'm talking about.

Slow but steady...

the three front primary case screws (the larger ones) are tapped into holes drilled through into the crankcase.
So if there's sufficient oil in the crankcase it will escape via the bottom hole as you have found.
Also to be aware of is to use the correct length of screw as too long ones will foul the crank web.

Cater? is this Dutch for crankcase, my education continues  *smile*

Aah I was too quick to judge, I thought it was the level hole, but indeed this is the big screw hole.
Thanks for clearing that up.

And for your education you shouldn't look to me, because that should have read "caRter".
and while thinking about it it's the wrong name. I indeed meant the crank case, an oil carter is the same as an oil pan.
I thought is was an universal name:)

Thanks for the info!

Hi pim, while you have the primary case off have a look at the reverse side ,you'll see towards the clutch end 2 castings insider the case with a gaps in the lowest is the drain the slightly higher is the level plug mark the nd in red so after 6 mths (  longer ) when you drain again you'll know which is which regards Bobh

One should use the correct terms, but for us foreigners it's sometimes confusing. Americans use the word "carter" a term we also use in Dutch, but the British use the word "sump" (which I personally like more. It sounds as "dump", a place where all the rubbish ends up *smile*). And there's more of that; gas tank or petrol tank, fender or mudguard etc. *conf*
And I'm not even talking about Australian English here *countdown*
If you've got a Haynes manual, on the last pages there's some British-American translations. Fun to read!

Good Idea Topdad! I just read in the original manual that they were originally red?

All those terms, you live and you learn... but correct usage of them is handy dandy.
Am I correct in saying that the sump on the crankcase on an a7 is the small square 2" by 2" really shallow bucket? (i use bucket for an lack of better term)

In other news:

While tidying up the edges of the primary case I found an connection from the case to the frame that looks like it should be connected.
But it isn't in my case... I guess it should be, but there is quite a lot of space between the two.
Any thoughts?

 Hiya Pim, the sump is simply just the bottom of the crankcase. The square thing is the sump cover plate, or if you like, you can call it what you like, and if there's a degree of logic and it's catchy might just be adopted into common use. ... *smile*
 If the gap is what I think you mean, there should be something on there, just add washers to that thickness, so there's no stress in or out when bolt is tightened up

Hi Pim,
That gap varies from bike to bike,
Refit the front screws where the oil leaked out with temporary spacers that simulate the outer cover being in place, then check the gap again
use a stack of washers to fill the gap and then a bolt and nut to secure

It is very important not to strain the case,

In your photo the primary chain looks very tight ???
About 12mm up and down play at the tightest point is correct

Thanks for all the tips and knowledge, I also noticed that the rear chain is just about to touch the primary case. but that might be becouse the backend isn't bolted to the frame. I'll check there is no tention on the case.

The images are edited with Photoshop, but you can use the gimp(linux) aswell, best of all it's freeeee!

For any quick fix & editing of images I am (as always) recommending Photofiltre Free. Small, fast & easy to learn. Arrows etc and any text+font+color+shadow etc no problem.

And sorry for the offtopic ( > Forum Info & Help is open for pc-stuff discusions).
But sticking to topic somehow, see picture  ;)

Pim,

With the inner primary cover already in place, you might be made crazy by trying to get your washer stack in place between the frame and the tab on the primary cover. What I did was to measure, with my caliper depth gauge, approximatly how thick the stack must be. Then, I took some cyanoacrylate (super-glue) and glued the stack together so that it could be inserted from behind in one piece. It took a couple of tries to get the right stack height, but if you just use only a tiny amount of glue, washers can be separated from the stack easily enough to make the adjustment.
