Engaged front hubs and my oil leak

[Scallops]

Hello Folks,

Having had good opportunity to do some driving in Matilda, I am now becoming more familiar with her habits. One of these is to mark her ground after a drive. I had a leak from the top of the gearbox, which has been greatly reduced by fitting a new gasket to the filler plug atop the box.

But since I topped up my transfer case, I see I have another leak - it comes from above where the front drive shaft enters the transfer case. This is the amount of oil I loose in a day......



So - is there an obvious gasket or point where this is coming from, given the general location of the oil source as described above? Also - I have been driving everywhere with the hubs locked - might disengaging them help, since then the front drive shaft and axle are disengaged? I would then just intermittently engage the hubs to lube the upper diff.

Any thoughts appreciated!

PS - I'll disengage them for the drive home tonight and see if it makes any difference.

Did you over fill the transfer?

There is a gasket on the output shaft seal retainer, but the most likely places for it to leak are the hole for the locking pin for 4WD or the hi-lo selector shaft. there is no "O" ring on the selector shaft and with wear it is a place for oil to escape if the t/fer box is overfilled.

It may be a little overfull. Maybe I just wait for the level to "self correct"?

Series 1 gearboxes don't have an "O" ring on the locking pin.That's the pin that moves up and down as you operate the yellow lever.If it's leaking from there,there is nothing you can do about it.It's just a tiny "o" ring that's often overlooked even on later gearboxes.

Also, since I serviced the vehicle, including cleaning the oil filler and rocker breather gauze filters, the vehicle idles lower, and the exhaust kind of burbles off throttle decelerating. Didn't do this before.

I guess the vehicle was tuned before it had seen much use and perhaps the good runs it has have have "cleaned her out" to the point the tune might need another tweek.

Any thoughts?

Lower idle (and the burble may well be the result of this), could well be due to the freeing up of the throttle linkage with use, or even slight wear on the stop of the idling screw, again from a bit of use. It could also be the result of slight wear on the fibre block that pushes the points in the distributor (changing the timing), so a check on points gap and ignition timing may well be a good idea. This sort of wear on the points is not unusual when first installed - there may have been a small high spot that quickly wore off, even if the cam was slightly lubricated.

Dan, I concur with John. I had a slow idle problem with Leon for a while. This turned out to be a points problem and nothing to do with the carby.

Check your distributor/points/advance and timing first.

Hi Dan,

I'm happy to bring some tuning gear down to the Xmas party and have a look at it Friday night/Saturday morning if you want. Very easy to check points and timing.

Thanks mate - let's do that. Killer and I are going to have a "pre drive down to Canungra" fiddle with her too, because I don't want to cause any damage.

Folks - oil leak all sorted - I took the transfer case bung out and let the excess oil escape - and dropped some excess from the main gearbox too.

So now both boxes are at full but not overfull. This is the driptray 1 day later - great success!

PS - Killer and I shall set the point gap and timing tonight.
