does anyone know the stock gear box ratios on a blackfoot?

and the stock spur gear size?

I dont feel like ripping into the gearbox just yet and counting gears.

thanks

Which version Blackfoot??

From memory the original one had a 52t spur and 10tooth pinion (I could be wrong) not sure the final ratios.

The madcap/astute series spurs have the same inner gear if that helps but the are 0.6, not 32dp

oops

The spur was 0.6 but the inner gear is the same. applies to the Kingcab to I think.

I ripped the gearbox apart and counted teeth

heres the ratios so it will be on here if anyone else needs to know

The gearbox ratio on my truck is 3.05:1

However that is not stock, I noticed while looking at some other gears on ebay that mine is aftermarket.

Mine is the either the overdrive or underdrive setup.

The stock box is closer to 2.5:1

My spur is 48t

My pinion is 10t

I really doubt the spur is stock either.

The spur could be right. I got rid of mine many years ago.

xray vision

Best thing to do is go to the vintage Tamiya site and have a look at all the old manuals on line.
Site has an absolute wealth of info on anything,old tamiya.

hope this helps
