Gearbox breather?

Post by **ek9sid** » Thu May 07, 2015 9:35 pm

Hi guys. There's a pipe which comes out the top of the gearbox. What is it for?

As on my 5g, it just goes up and doesn't connect to anything. Any ideas?

Will stick up a photo tomorrow of what I mean

Yeah, it's a vent for the gearbox. There is supposed to be a rubber vent cap on the top of it as well, but 90% of ludes have lost these over the years.

Apparently it can be used to fill the gearbox up with oil as well, but I've never tried it myself

Ahh that's great to know. Last time I filled the gearbox up (around 5 months ago) the bottles had no spout on them so had to make a makeshift funnel/tube thing which leaked everywhere.

Only reason why I'm asking about it is my gearbox has lost a lot of oil and I can't figure out where it's leaking.

It won't be from there unless...

Pop a K&N breather filter on there. It will give you shorter gear ratios as the oil runs cooler.

I have used the breather to put a little fluid in the gearbox, but only when I lost a little when I removed a shaft. Do not fill a gearbox up this way as you do not know when the gearbox is full.

I guess you could remove the proper fill up plug, then pour the oil down the breather pipe and stop once it starts pouring out the proper fill up hole (As you would do anyway). I guess it's just easier for some to do it from the breather.

I just use a hose long enough to thread down through the bay to reach the proper fill up hole.

I might get one of these though...

The breather is meant to be covered with a plastic vent cap, rather than a rubber cover
