Outer Limits 4x4 Board

hey guys, got a question for those with knowledge of such things.

i dropped my gearbox oil on the weekend as i decided it was due a change and with a kakadu trip coming up thought it would be nice to have some nice oil in there for the prolonged heat it will cop.

so pull the plug out and out pops this with the drain plug.













the hi temp red that appears to be on it has nothing to do with me, it came out like that.

its cast steel, dome shaped, definately broken and has a little hollow inside on the broken side, as the pictures show.

the gearbox works fine, sounds fine and tastes fine.

shift quality was fairly shit going into first or second with the penrite oil, even after adding the suggested expensive additive.

now with castrol vmx 80 its like a new set of synchros have been put in there, shift quality is much better now.

there was quite a bit of metal fuzz on the magnetic plug when it came out, but there was the 2 times before that too, dunno what that means, maybe the shitty penrite oil.

so does anyone have any ideas where this may have come from and what it is that at some point in time is going to become a headache for me?

if i didnt know better i would say it was part of the housing from looking at the casting quality, but really i dont know.

cheers, andy

i think it could be the bottom of a bolt hole. when you put a bolt thats to long into a threaded hole and wind it in till it bottoms out then wind it further popping the domed casting off on the inside of the gearbox. best i can explain it . Thats the bottom of the hole and i wolud say the red is loctite or silicone.

Has the box been out or appart since you have had the car if so i would say a blot has been put in the wrong place. i wouldnt wory about it to much as it wouldnt have floated around.

hope this makes sence

No doubt that is exactly what it is. Someone has put the wrong bolt in a hole when re-assembling your gearbox at some stage. I wouldn't be to concerned.

oh, that makes sense, best guess is when i fitted the PTO, i cut longer bolts down, musta left one just a touch long

cheers for putting that worry outta my head
