Default Reliant axles upside down

I am using a reliant axle on my new trike, but is has to be upside down so that it goes forwards when turned by my xj650 engine.

When doing this, the little breather hole in the axle is then facing down, so im assuming it will leak oil out? If i fill it in, is it just a case of drilling a new hole on the top or does the hole have somthing special behind it??

I have also heard people say that the brakes need to be swapped round to work properly, as theroricly the axle will be in reverse all the time and the brakes wont be as efficient??

Any help will be appreciated.

fit a plug into the breather which then becomes a drain plug.
yes swap the shoes around as they might well grab badly

I can fill the breather in with weld, but still need a breather surely? Is it just a case of drilling a small hole through the tube on the top?

They've got a small hole in the top that has a Pin in it, they often get crud around them and are difficult to see.
You must have a breather or they can blow seals...................there's a joke about that!!!

If you turn them upside down be careful not to over fill them with oil!!

Cheers'en.

yeah frost on me top lip

aha, that explains why never seen it, I was told by someone that they vented out the ends of the axle as opposed to the normal method, on this assumption I have always run them upsdie down and not done anything about the vent, none have leaked???

and yes they did have oil in them LOL

Mine has no pin in it.....? I turned it upside down today and after a few hours it felt a bit slimey all round the hole. All I really need to know is if its just a straight hole through the tube, because if its that simple I will move it to the top.

You need to vent , the axle needs too breath, the mrs trike never had vent on hers ,
and the painter had painted over original ,
we were forever having to do shaft seals and got sick of oil soaked brake shoes because of it.

Sean from TTC who's doin me max conversion does a neat little trick with a k&n filter to top off !!

sorry about the size of the pic

Cheers for you help everyone. All sorted now, spent today swapping the brakes over - what a pain in the arse it was getting the hubs off!! and made a new breather hole in the top.

If you drill a new hole in the diff, for f@ck sake make sure you get ALL of the swarf out before putting it back together.
I say "ALL" of the swarf.
And the broken off drill bit.

I only say this becuase I have had to rebuild a rear axle for some F@CK who didn't listen and drilled through diff casing straight into the crown wheel and snapped off drill bit............................................... .................

simple rule of thumb , (although someone will contradict) if your output on the engine is on the left , as you sit on it then the axle is more likely upside down , start lookin for the holes in the tube.

My axle is upside down to work with my XJ650 engine. I have made a new vent hole in what is now the top, blocked off the old vent hole, and swapped the brakes across. The brakes are dead easy to do if you can get your hubs off!! I sheared off the handle on my puller getting them off mine, but got there in the end and at least now I know everything comes apart in case I need to do bearings or seals in the future.

I took mine to my local tech college. A couple of the motor mechanics lecturers are into hotrods. I used their hydraulic bench press to pop the hubs off the tapered shaft ends in a matter of seconds.

Where did you put your breather mate?

mine has one in the tube i can fill but i dont want to drill a new hole in the top of the tube as it will put swarf into the unit. i suppose i could drill through the main diff casting with a rag under where the hole will be to catch the swarf, then put a little filter on it or mesh or somit.

i will swap the brakes on the mgb axle when i can find a big enough socket/spanner i dont think the brake pressure will be affected by the axle being upside down but still i want the brake cylinders back at the bottom of the mount plates

OK HappyBiker, your answer sounds very logical to me, issues now are ...

1) Should there be a small DRAIN/VENT hole on each side of the Diff on the bottom of the axle?
&
2) Can I drill the small hole(s) without stripping down the axle?

3) how do I determine if the brakes are the correct way round now that it appears that me axle is mounted downside up?

All help would be appreciated...........

Once again HappyBiker thanks very much all clear now, just got to source the bits for the handbrake, got a nice lever from a minicooper, and get it all together.

Once again thanks for the info....

I know for a fact that my breather hole was on the top when on the reliant, as when i turned it over for my trike it was on the bottom and leaked oil. It wont contaminate the brakes because of the seals behind the hubs. I have turned my axle upside down and moved the hole to the oposite side from where it was originaly and its ended up on the top again.

i dont know about reliant but my MG axle had a breather hole on the top which is now on the bottom. i intend to block off the hole and put a new breather in the top but its definatly not to let the oil drain out.

you state that if it leaks oil it means the diff main seals are gone? i presume by this you mean seals between the diff and the half shafts to stop the tubes filling up with oil?(are there really any seals there? i havnt stripped a reliant down) however if so then there souldnt be any need for a breather on the the tube only the diff itself. and if there shouldnt be oil in the tubes then there shouldnt be any reason for it to get past a seal onto the drums?

the breather hole will leak oil if its on the bottom of the axle as oil is designed to get down the tubes to the hub bearings at the end of the tubes. the seals should then stop the oil coming out,

right?

well thats how my MGB axle works and i cant see the reliant being that different other than having different ratio partsand a different casing
