Gearbox

It's winter, so it's time to work on my 365GT4 2+2. The gearbox and clutch are my projects. I Have started to remove the gearbox from the car. It took me a day to get it out. I would like to measure the synchro's. Specially the one for 3rd gear. There's always a little "grind" when trying to shift to 3rd gear. Except when shifting is executed very slowly, the noise is not present.

Next issues I have to overcome are the ringnuts. I need a special tool for these, which I don't have.... Has anyone tried to build there own tool or is there another way to loosen these bolts?

if you are referring to the rear main shaft output nut with the 4 notches. I just made one from tool steel. This type of nut is used on many transmissions and wheel bearing spindle nuts. I found that building the tool with replaceable teeth that are hardened is a more durable solution.

 

Thanks Mitchell, that's indeed the tool I need. Would it be possible to post a picture of your selfmade tool, as an example?

Have you tried Mr.Fiat-6-in-line at www.classicpassion.nl? I vaguely remember that the 2300 Abarth (or was it the Fiat 130 gearbox) has the same type of nut. And if I am correct he surely has the tools!
