GEAR BOX OIL REPLACEMENT

(project by Jan Willem)

PARTS TOOLS

Gearbox oil - between 2.5 and 3 litres

Allen key

 

WHAT YOU HAVE TO DO

STEP
ACTION
1
 If you look under the car, the gearbox is behind the engine. There's one plug in the bottom, which you can unscrew with an allen key.

The gearbox oil should be much clearer than engine oil you should see the difference when it is draining.

 

You should also notice a collection of swarf or bits of metal on the gearbox sump plug. This is because there is a magnet on the plug to collect bits of metal so they are not crushed between the cogs, this helps to reduce cog wear in the gearbox.

 Then there's a second plug at the front of the gearbox, a little way up for filling up (also allen key). Unscrew this one as well.
3
 When refilling, first put in the bottom plug (of course!), then fill up through the second plug.

The gearbox oil filling hole is just behind the air filter (DTR use this bicycle pump device to inject the oil into the gearbox). By the way not all gearbox oil is red in colour.

This picture is of Redline MTL fully synthetic gearbox oil, the barchetta gearbox takes about 2.5 American Quarts of oil (the units Redline MTL is sold in)

 The level is correct when the oil is upto the level of this plug, i.e. when the oil starts to flow out. Easiest is to use a funnel with a hose. You can insert the hose from the engine bay into the hole of the top plug...
Sounds a bit complicated, but actualy quite simple....
