Rear diff pan
« on: February 19, 2009, 21:26:16 »
Hi All

I've got an MOT in three weeks and have just found that my rear diff pan has a pin hole in it  :'( :'(



I can weld and will do it myself , but , the new pan will be pressed steel and I belive the axle casing is cast...

My question is ..... ;)

Will I be able to mig it together with normal mig wire or will I need to get something special ???

also whats the best (cheapest ) pan I can get and where from ???

I'm also thinking the bottom fo a gas bottle might work  :-k

 You know me if I can do it for free I will :lol: :lol:

Just weld a small piece of metal over the hole! Thats cheap and it fixed mine after a piece of diff had come through!

lee clean it with a wire brush and check it hasnt spread to all over the diff pan, if not then cut a small patch of metal and mig it on, just make sure you get the metal clean and dont blow holes,, and drain the diff oil and then put fresh in after

I fear that there may be more holes under the rust so there may well be nothing to weld to on the pan ... :'(

I need to get a plan in place before attacking it with the wire brush If it is a mess I need to fix it there and than cause I need it daily for work 8-[

You will only fail the MOT if the oil actually drips out during the MOT test.  Chewing gum until you have more time!

The axle is a thick steel pressing so no issues with wleding a new pan in or bodging up the one you have.  If oil isn't peeing out then leave it alone 'till after the test.

AS RRB says, the axle casing is made from 2 halfs of steel pressed to shape and wleded together. MIG welds it a treat and a 6mm thick you will be hard pushed to burn through it with a 240volt mains welder.

As also said you can getit through an MOT without welding, though when you do change it then consider more substantial alternatives to the standard pressed steel items. My diff pans are now made from 6mm pressure vessel end caps and no bolt on diff guard I've ever come across can provide the level of protection that theses provid, combined with maximum clearance and no mud traps. My rear one bearly suffered inside when the diff went pop.

pressure vessel


As I thought bottom of a gas bottle  :dance: :dance:

It is leaking I had a look tonight when I was doing my side exit exhaust  :'(

it looks well rusty so I will be replacing it before the mot .

Lesson in female lodgic ...........

If I don't fix it and just bodge it and it passes the mot then the wife will winge when I say I want a new one and make me leave it bodged  :evil: ..

However if I tell here it's for the mot. she will let me do it now and approve the cost :dance:

see method in madness  :lol: :lol:

I know people that have used the bottom of a fire distinguisher before as well. Local fire Service will probably have some dented old empty ones kickign around,
