Leaking gearbox oil plug

[pietmeyer]

Hi Guys

I have posted under accessories wanted but not sure how many check that out and need some advice.

My 582 e-box drain plug is stripped and now leaking oil. It is the plug at the bottom on the cover side Just from this statement I probably make it rather clear that I am not mechanically inclined and not sure of the terminology

I guess I can have the cover remove and find a place that can re-thread or if anybody has a spare cover from a scrapped box lying around please let me know. If you know of somebody who can re-thread it or who has done it, also let me know

Thanks'

So, is the actual plug stripped, meaning you can't remove it to replace with a new one, or is the casing thread stripped?

[pietmeyer]

Casing thread is stripped. Plug can easily screw in and out but not tighten

Piet, I know you can get helli coils. But for that application, I would be a bit hesitant. I would try and get another cover.

What thread is that plug?

Does anyone know if it is imperial or metric?

Why would you say that Vernon? What if I use plumbing tape and maybe add another washer? The problem is that the plug goes in but just does not tighten. Just as it seems like it will tighten, it is loose again. Seems like it is that last little bit that is the problem

Those covers are expensive and seems to be a moer of a job to just replace also. Would like to go for a cheaper option but still safe option

I'm not an AP...but the same thing happened to my sump plug on my old bantum bakkie... I bought a different plug (slightly bigger) and re tapped the hole to the bigger thread. Took me about 15 min and cost less than a spark plug.

Is this not maybe an option?

[vernon11]

I must confess Piet. The Heli coils are good. The solid ones that cut their own thread, not the ones that the hole has t be first tapped. I have seen them and used them in many applications. Taking into account the difficulty and expense of getting a new cover, I would use one. I know I am contradicting myself here. Thread tape is not necessary, nor are two washers. Your best bet would be to go to an automotive engineering firm. to get one. they use all sorts of sizes. They might even fit it for you. Let me know how it goes.

It is metric.

Piet, sal met jou praat, ek het 'n idee of twee!

exactly why i asked what thread it was --

Hey Alan.
Did you get an AP to sign it out?
It is a good idea, and maybe the best option.

Nope...my AP doesn't have a rating for a Ford Bantum....don't think the CAA would give a damn...

I also don't trust helicoils (just from my lawnmower shop days)...I think this would be the best and at least you don't have to strip the whole thing to fit a 2nd hand cover?

Hello Piet,
I have the same problem with my e-box.
At the moment the thread is sealed with Locktight.
There are only about 4 threads available on the case so a Helicoil most likely will not hold.
The best solution is to take off to the gearbox case and get a good engineering works to machine a brass insert for you.
I guess the best design will have a shoulder on the inside so it can never pull out.

Someone suggested to me to get the thread aluminium welded and tapped to fit the original plug.
I don't know enough about Al welding on alloys to comment on that.
good luck!
