Project 6-speed

[Mos]

5th is perfect for cruising around at 60 and 6th is great around 80....can get on a freeway put it in 6th and just drive for hours....

I'm pretty sure that's your diff ratio and not the box itself.

Yes you are probably right(cause you can pull engines apart ), but it's still a sexy box

[love ke70]

this is a V160 right?
the gear ratio of 5 and 6 in the V160 are almost identical to 4th and 5th in a W58...
1.000 and 1.000
.790 for the V160 and .783 for the W58.
so yes it will be the diff ratio, but the gearbox, having the same ratios as the W58, ensure the same sweet driveability is kept

I was having a browse on the Castle Hill Toyota website and stumbled across V160 specfic oil. Guess how much it is?! $145 for a 1 (yes a 1) litre tin!!

[Norbie]

Yes the genuine stuff is crazy expensive. I don't think I'll be using it if an oil change is more expensive than buying a whole W58!

[Draven]

it's ~$120 for 2 litres from a sponsor of sf.com.au

[grahamd]

Expensive oil yes, but it is supposedly the best oil for the box.

I used Castrol Transmax Z - the only other oil recommended, and the synchros are a bit tight on the 1-2 change especially when cold. Was thinking of flushing the box and changing to the genuine oil to see if it makes any difference.

And before anyone says the synchros might need replacing the box was rebuilt before fitting to the car - if you think the genuine oil is expensive that's nothing compared to new synchro's. But hey - it's a V160 and worth every cent it cost. Awesome ratios - that's why you fit one of these.

By the way I have the complete V160 workshop manual if you need any info.

[Mr Ed]

V160 gear oil is longer produced either so if you want it, get it fast!!

[Mr Ed]

Any news on the parts from Toyota?

[Norbie]

Apparently all but one part has arrived, ETA unknown at this point.

[Norbie]

Parts have arrived! Many thanks to Lance for organising it all for me.

Hopefully I'll have it all fitted in the next couple of weeks, assuming I can figure out how the whole mess fits together. The fact that I've never seen a 6-speed clutch up close, much less assembled/disassembled one, certainly won't work in my favour.

[Negative Boost]

Gee, didn't think the clutchs would be much different, got any pics?

[Norbie]

The V160 has a pull-type clutch which is much more complicated and annoying than the simple W58-type arrangement. The box of parts I picked up tonight contained at least a dozen individual pieces, not including the actual clutch/pressure plate assembly!

[Big rob]

What advantages does a pull type clutch have over a push type? I'm thinking there is more driver feedback since it seems the clutch fork is attached to the pressure plate rather than just pushing against it.

[Norbie]

I believe higher clamp pressures are possible with a pull-type clutch, but I'm not really sure.
