Sorry can't help you much (have different clutch), but I have seen some pics, will see if I can find them.
It's funny that u mention merc. aust., I went into the local spare part department (run in conjunction with some other car brands), to buy some OEM sealant: Chassis number please! -> Me korean copy!
Went and bought Toyo stuff!
To merc's rescue I have to mention, that the local dealer gave me a lend of a RIV tool over the WE, for free!!

BTW, what makes you sure it's the belt and not the pulleys?

Cheers,

Kay
