Courtesy of Pro Alloy Motorsport, I have a gearbox breather tank to add to the gearbox. Fitting one allows about an extra half litre of gearbox oil to be run in the gearbox, allowing for better lubrication and a larger volume of oil will dissipate more heat.
First the batter, and battery tray have to be removed. This give access to the top of the gearbox. The fill plug is removed and replaced with the supplied fitting to convert the fill plug into a breather point. Here it is fitted into the top of the gearbox. The second breather point can be seen top left of the picture:
The breather tank is to be bolted to the bulkhead, so an M6 jack nut was installed into the bulkhead and tightened securely:
A hole was then made in the bulkhead sound deadening with a soldering iron to allow the bolt to pass through and into the captive nut:
Both lengths of hose (one 10mm and one 8mm) were then measured and cut and then fitted to the two breather points with hose clips and then onto the breather tank on the bulkhead:
And here is the breather tank bolted to the bulkhead:
