how can we identify which parts we need specifically, or actually, how expensive are these parts new from toyota?
Also want to know if this is right! I want my speedo to be accurate dammit!
Just checked, yep turbo rolla, thats correct.

Okay, so a 21.6 gear will do it then you reckon? I rang a while ago about a new speedo drive and the "full" price was about $50, but i could get it for about $40. Will make some more enquiries though. But im also keen to work out exactly what you need to ask for (ie is it as simple as asking for a 21.6 ratio gear?).
No, there are two parts.
There is a metal gear inside the box, the 5 or 6 tooth. This is $60.85 for a 5 tooth. 33481-12030
Then there is the plastic speedo drive that mates with this and is sold complete with the shaft and drives your cable This is about $49. Not sure if cost varies depending on number of teeth. The 22 tooth was easily available, may be harder to get others such as a 19 tooth, which I need at some stage. Possibly needs to come from Japan.
This is the part i initially got the pricing on (a 22 spline speedo drive). So am i correct in assuming that a 22:6 would refer to a 22 spline speedo drive with a 6 tooth metal gear for example? That much closer to getting it sorted out! Thanks!
Yes thats right! haha, Anyone know how easy it is to replace these, are the 21 splines common? cheers.

Well the plastic gear on the spline is easy to replace. Essentially undo one bolt and take off the retaining tag then pull it out.
The 5 or 6 tooth is inside the gearbox, not sure how involved it is to change that but presume you need to split the case. I have not looked into that yet however.
Had a look in the AE86 Manual (online version), and found the following:
This is the speedometer driven gear, and like parrot said, looks like a simple matter to remove as its basically where the speedo hooks up to the gear box.

This is the speedometer drive gear (different to above, as this is what drives it). From the looks of the picture (exploded version), it apepars it may be on the inside of the case, as parrot guessed:

Look forward to someone confirming this though! :2thumbs:
Although note the first diagram shows the reverse light switch.
I know this is old, but for completeness, I can confirm a late T18 (TE72) T50 has a 19 tooth plastic gear.
