Hey all,

I posted a little while ago about the fact that my "Selectro" freewheeler is leaking some grease.
I took the wheel and drum off a minute ago and have found a small amount of grease weeping from the (?) axle too.

Can someone more knowledgeable than I have a squiz at the pics and let me know what the likely cause is?

It seems to be grease, not oil.

I recently replaced the drum, shoes and cylinders on this side and do not want to risk any grease/oil contamination!

Cheers,
Ash

Can't comment on the Selectro hub leak too much, as I am not familiar with them, but that leak is within the hub. The other one is the seal on the inside of the hub (not a big job, but a bit messy, and it is possible the surface the seal runs on is worn excessively). Should be oil, not grease, although if it is only a very slight leak it may look like grease. It could be grease if the wheel bearing and the swivel are grease lubricated - swivel is supposed to be oil, and using grease, although not the special "one-shot" grease will cause premature failure of the top swivel bush.

Mmm.
My swivels are filled with grease...largely. (ive begun to top up with EP90)

So basically I should be buying hub seals?

your hub seal looks reasonable....

if your vehicle was running grease packed bearings prior to you purchasing it or you've covered 50K Km then you need to pull the hub down to clean, inspect and regrease the bearings. (and replace the hub seal)

I think one of the axles I have out the back has a selctro on it like yours. do you want me to check that out for you?

For spelling call Rogets, for mechanicing call me.

Yeah OK, probably time for a strip and clean.

The only history I have on the vehicle is that the swivels and seals were replaced about 9 months before I bought it.
I know the mechanic who did it and would not be surprised if he was too lazy to do the hub seals etc while he was in there..

I have no idea how many km's its done, the clock has gone around at least once.. (at least!)

If you have time to check out that axle of yours I would definitely appreciate it!

Ash, inner hub seal definately and outer leak will be the Selectro hub. Attached fitting instructions with exploded view of hub. With luck it'll just be the 'O' ring.

Cause may be a non functioning axle breather perhaps or are the front swivel pins completely sealed from the inner axle case (I don't think it could be but I've not pulled one apart for twenty years. Someone else here will know.

If you've been topping up the grease (bad) with gear oil it could be causing a bit of extra pressure in the casing too perhaps. Grease was probably put in because of leaking swivel housings though so expect the worst if you get rid of it.

Cheers
Lakey.

Lakey your a legend, that diagram is exactly what I was after.

I think (hope) it is just a worn inner seal, hopefully just age/wear rather than caused by other problems.

The axle breather is OK, I cleaned very recently.
It spits oil onto the axle casing with regularity.

Thankfully I know the swivels are OK, the grease put in was the "one shot" which came with the swivel kit when the PO fitted them about a year ago.
New swivel housings and seals.

I have gradually been adding oil as needed because I dont like the grease much, none has leaked yet.
