How often do you change your gearbox oil?

[Djw John]

what colour garden hose would you recommend? ?

cheers guys, will get the stuff ordered and get it done next week, first sprint is the 24th!!

Yellow. The green stuff costs power. Fact.

I usually go for yellow too, I heard that it flows better

I got this one. All 380mm in length.

When I was looking at it on my phone before buying my mrs saw it on my screen and thought it was something entirely different....

Calm down, it's not all about who has the longest funnel.

If you've got it flaunt it

Is anyone else's proper black when drained?

Nope, not even in the racers and they get serious gearbox abuse and are only changed once a year.
Black suggests either contaminants getting in somewhere or wear metals really - could be oil overheating but that's only likely if you've gone with a too-thick oil for the 'box. have you tried running a magnet through it to see if it's bearing/gear particles?

If you shine a light on the oil are there many shiny bronze/gold particles in there? Could be syncro wear from incompatible fluid (often happens if an aggresive EP fluid has been used one a box with brass/bronze synchro rings as it attacks the metal.

Well it shat itself at the weekend so I think there might be metal in the oil now ?

 

[PhillipM]

Well, guess you found out that the black oil wasn't right then

 

[Djw John]

Pretty sure it's been my welded circlip but I'll confirm soon enough.

It's not a box that owes me anything, just wish it hadn't gone a hour into a 5 hour trackday

 

[Coops Mk1]

Diff float will cause excess heat which will lead to the oil changing colour and darkening so that was probably the issue. The welded clip will do nothing to sort the play in the diff and fact it popped again and took the welds with it means those diff bearings are proper fucked

 

[Djw John]

That makes a lot of sense actually Ben!

I've only ever changed it when I've changed the box ? going to do the van this month as it's 19yr old!

 

[Jall]

I change mine every time I accidentally pull the LHS driveshaft out. [emoji2357]
