swing axle seal question.
Anthiron - May 25th, 2006 at 01:36 PM

ive got a passenger side rear that keeps leaking. pulled it off a few times. new seals etc.

basically you have the gasget inbetween the bearing cap and the backing plate.

the plastic press in seal in the bearing cap.

the rubber o ring which fits into the lip of the bearing cap.

and then u have another gasget that doesnt fit in between the backing plate and the axle tube. but i modifyed one to fit.

everything is tight.

stil leaking.

what am i missing/doing wrong?

from memory after 11 is the backing plate and another gasket like 11.
12 & 13 should already be there then its 14 to 21 using new stuff from a axle seal kit. i dont think 15 is used anymore?

thats what i did. 1st time it leaked because somehow 16 got chewed up. after i put a new 16 in it worked out fine.

hope that helps.

Do You know where its leaking from?

seal isn't leaking?

Use gasket cement - on the gaskets...
permatex or Aviation jointing cement are good...

or You can use silicon [silastic] on the gaskets...

but I don't trust any paper gaskets...

so there's no gasket between the stub axel and backing plate? the kits usually come with two of the same sized paper gaskets...

i used both, one each side of the backing plate. anyway, that was not where my leak was from it was past the axle seal into the retaining hub and out the little drip hole at the bottom.

welcome to the shitty world of swing axle leaks . ihave had so much trouble with my cars ,what i did was get german axle seals and replace the spacer bush (with the o ring taper that the seal runs on ) even tho mine looked ok ,so 3 months they havnt leaked again.:beer:beer:beer


Anthiron - May 25th, 2006 at 05:45 PM

yes the kit came with 2 of the same sized gasgets......they fit well on the inside in between backing plate and bearing carp but dont fit in between the backing plate and axle tube

i did have a tub of permatex which rolled under the bench somewhere never tobe seen again. so i bought a new bottle of it.

ill pull it off again in the morning and give it another go. this is shitting me to tears!


helterskelter400 - May 25th, 2006 at 05:48 PM

i know what you mean about the imperfect fit. i just let the bearing cap cut in.

also as topless says, a friend always sait to make sure the spacer face was in tip top smooth shape or else you are asking for troubles.

usually if they leak it is cause by the axle nut not being tight enough to locate the seal on the seal runner.

Make sure your axle nut is real tight and also check your seal runner is free from marks and grooves.

Next make sure you axle isn't stuck in, check it against the one that don't leak and make sure they both have the same amout of thread through the nut.

Also is this a hybrid baja ? ie did the axle allways leak or has it just started ? There are several differenet bearing caps and if you have the wrong one it will leak.

Lastly if all else fails remove it all and leave the gaskets off the backing plate and under the bearing cap. This will allow the cap to seat the seal furtehr up the axle which will in turn reduce the chance of oil leaking out. Don't forget about the shims.

If you look in the manual they will only usually show one gasket not two, this is for reason.

Hope that helps.

spacer - is that the cone one that goes onto/around the smaller rubber o-ring? or the big washer?

Mine's torqued up correctly and it stell leaks all over my brake shoes..

I also did double up on the gaskets betweent eh bearing plate and the backing plate, and it still leaks.. argh.. the other side is fine, but i'm afraid to pull it apart in case i disturb the seal and then I'll have TWO leaking axels...

sorry for hijacking.. seems like it's a common occurence


Anthiron - May 25th, 2006 at 06:28 PM

looks like im not alone....thats some consolation.

brad it has leaked before but have also fixed it before and gone for months with no leak.

the axle isnt stuck

alxe nut is tight as

ill see how i go tomorrow.

thanks everyone for the help


oval TOFU - May 25th, 2006 at 07:55 PM

yeh, let us know how you go..


ancientbugger - May 25th, 2006 at 09:13 PM

Hey Nick I had sort of the same thing a few months back with the buggy after pulling it apart a couple of times and swearing a lot I just tightened it to a torque setting of FU*!+ing tight and it stopped leaking.


Anthiron - May 25th, 2006 at 10:03 PM

ill get some mates around to jump on the bar with me:tu:


hellbugged - May 25th, 2006 at 10:50 PM

didn't see any mention of the o-ring that actually goes on the axle under the spacer.??? oil and roll/slide this onto the axle as far as possible and check thats its not curled at all

i was taught to load the rubber gasket into the bearing cap (after tin washer), and the spacer into that mounted gasket before putting, the now fully loaded,bearing cap into position......works a treat.

the o-rings are the bits to get right!

'lil one stops oil down the axle

big one seals oil from behind the backing plate

main rubber gasket keeps bearing cap sealed.

as Brad pointed out, it can be done without the paper gaskets

don't add extra gaskets that will make it worse

bloody great.. i'll try pulling one of em out then and see if that stops the leak..


Anthiron - May 26th, 2006 at 11:50 AM

ok well just put it all back together.

gasget on both sides of backing plate. new o rings. permatex on contacting surfaces, nuts and bolts are tight.

time will tell


Anthiron - May 29th, 2006 at 01:18 PM

still leaking........:cry


oval TOFU - May 29th, 2006 at 01:19 PM

biach


Anthiron - May 29th, 2006 at 09:57 PM

hang on amend that.

had a better look this morning.

wat i thought was trans fluid was actually cruddy water which had dripped down thru the drum and was pooling in the wheel.

might have fixed it after all fingers crossed.


hellbugged - May 29th, 2006 at 10:08 PM

:tu:


Anthiron - June 5th, 2006 at 12:09 PM

ahhhhhh.

well that lasted about a week or so.

its leaking again.:grind:


toplessbug - June 7th, 2006 at 07:17 AM

get a NEW spacer and a GERMAN seal not those crap 5 buck kits that come in a generic plastic no name bag
