What to look out for when buying gearbox?

[slystiguy]

Hey im going to look at a old rs legacy box for my suby . Guy reckons its good condition (150kms) an working fine.

I've never brought a gearbox before so is there anything I need to check before I buy it?

an will it be ok to use on an v2sti? ratios match up but I read my box has double cone syncros where as this one doesn't... and there is quite abit power difference with my car an legacy...

Its cheap,local, an matches my current ratio unlike any other box on Trademe in my price range

oh an my box is a ty752vb4aa

First thing you do is inspect the magnetic drain plug for possible damage(ie teeth etc) normal buildup from bearing wear is noemal thou.

check to see if the box has been split open before(ie new sealant) as it could possible have another gearset from another box and could be weaker than original spec.

Double cone syncros allow smoother shifting especiallly when down shifting, but the double cone syncros also have a weaker hub and have seen the double cone syncro hubs crack in half before.

Doubt you will notice the difference between the 2.

Makesure that you can select all the gears and spin the input shaft and check for wear, the earlier boxes can be subject to bent alloy selector forks...(hence the double syncro upgrade in the later boxes to combat this problem)and the steel selector fork used in certain early RA boxes.

And check the old oil...

Golden flakes mean worn syncros and metal flake means worn bearings but remember that there will be some wear and tear obviously.
