Gearbox oil change

[DrewCole]

In the front of the service book it'll have a production sticker with a three letter code either FZQ or FML.

The FZQ box can be modded with a shim, the FML, which I have, can't.
Which is why I have a new shim and cap at home, which I ordered by mistake!

No worries, if you need a shim and end cap let me know!

Good news Im using FZQ gearbox

Car on a level surface, pour in oil until it starts to dribble out of the fill/level hole. Ideally use a funnel and tube from above the car (not my idea, but a good one). Capacity is apparently 2.6 litres.

The type of oil required depends on your gearbox code, unless you do a complete drain and refill. Two different types of oil have been used by the manufacturer, and they warn very specifically against mixing them: -


"There is a new mineral gear oil API GL4 SAE 75W (Hypoid) in accordance with TL 726 /Y. This type of oil can only be used in gearboxes where it is specified and must never be used in gearboxes that incorporate the previous oil API GL4 SAE 75W90 (Synthetic, high performance)"

"Due to the incompatibility between these types of oils, they must never be mixed as they change the properties of the lubricant."

A while ago the following list (for 6-speed boxes) was posted:

Gearbox code and oil type -

DRP / FMP / FHA / FHT / FEK / FEL / FGT / FGV / FZM / FZP / FMQ / EFF / ERF / FMH
Gear synthetic oil API GL4 SAE 75W in accordance with standard TL 521 71 (Spare no. G 052 171 A2)


DRV / EFY / EUK
Gear oil API GL4 SAE 75W 90 in accordance with standard TL 521 57 (high performance synthetic oil)

Some five-speed boxes have the following original filling

EBD, EBF, EBJ, EBM, EBS, EGW
Oil for pinions API GL4 SAE 75W90 (Synthetic, high performance)

EGR, EGS, EGV, FBK
Oil API GL4 SAE 75W (Hypoid)

Note that these oils have practically identical specifications, the same API numbers and TL standards. The only difference appears to be that the synthetic (older spec) oil is multigrade and the newer mineral oil is single-grade 75W.

It would be useful to get a more complete list, but I expect only a dealer can get hold of the information easily. In addition it would be good to know just how thorough you have to be to flush out the old oil if you have to refill with an incompatible type: will the puddles left in the corners and webs of the gearbox casting cause a problem?

Any idea what type of oil should be used for a FZQ gearbox??

Stops excessive engine movement backwards and forwards.

Is it worth upgrading it, and how hard is it to fit one? As ever since stage 1 Revo i always spin the front in first, always need a rolling start.

Also dont think i have an allen key that big, would this do the trick?

What are you trying to do?

Gearbox Oil change, want to make sure i have the right kit before the weekend, as going to do it at the same time as fitting the shim.

 

[Bigjohn84]

That won't fit, you need an M16 spline security key
