TD5 oil drain plug thread

[fraser130]

Does anybody know the size and pitch of the oil drain plug thread on the TD5?
I want to get one of those drain taps for it......

I'd be interested.

But I thought the "taps" hang down so I was always concerned it would be subject to getting hit. Thought its tucked up heigh.

I wouldn't mind one of the magnetic ones but (sorry if this is a little off topic).

[fraser130]

They do stick down a little bit (the one I'm looking at sticks out 20mm), and considering how high the sump is, I'm not too concerned, and I rarely do serious off road.
They look pretty strong too.

Are these what you are looking at:
4x4 Store (http://shop.difflock.com/defender-drainplug-p-40.html)

They are very good, direct replacement for the standard Landy plu, but they do hang down a bit. For that reason I havent got one fitted to my Defender.

Excellent if your Defender doesnt often get into the serious stuff, but I dont like the prospect of catching it and dropping 11 Litres of oil!

Certainly make changing oil MUCH easier and cleaner!

[fraser130]

Same Idea, but I think this one (http://www.fumoto.com.au/) looks a little more robust. they also show one fitted with a hoseclip to further prevent accidental opening (flying debris etc).

Any experience with these anyone?

I like the idea of being able to drain a little oil, or to do it into 2 litre milk containers (being able to start and stop).

Usual disclaimers apply: I have no affiliation.....etc...

Hi Fraser

I just looked at the Fumoto site for there drain plugs they only had Discovery listed in in the Land Rove models but I think they be the same size as the Defender, it's 14mm x 1.5 pitch drain plug is F-106 and coast $41 plus $8 deliviery...

Hope this helps

Well, I ordered 2 (one for me, one for Dad)using the website's (and Ashley's) recommendation, I went for the nippled version, I'll let everyone know what I think when they arrive and are fitted.

Mate I went the "un" nippled version.

My next oil change is December 09 so by then I'll know if I should screw it in or not. Looking forward to your feed back

[scott oz]

I just went out and checked and the 110 Def TD5 has a collar around the sump plug. A quick measure shows the inside diameter collar to be 24 mm. measuring the Fumoto shows seating base diameter of 25mm.

I'm not sure if you turned down the base diameter of the fumoto valve you would get enough clearance for the valve to seat properly, The alterntive would be to "pack" be base up with washers. Or grind the collar off the sump to allow the fumoto valve seat.

I note fumoto say they have some adaptors so I'll give them a call on Monday. Otherwise I think it may be the UK one?

Fraser130 how did you go

Note my measurements were rough and with the sump loug in

[fraser130]

Scott, they had no nippled ones in stock, so he's sending them next week when they come in. Hold on with the UK one, I have a mate who is an amazing machinist, if they need changed, I'm sure he can do it, and you could post me yours and I'll get him to do yours too.
I'll let you know as soon as mine arrives.

Thanks

If you are playing thread games PM me. I can supply taps and dies in virtually any metric thread you can think of and some you would not believe exist.

[fraser130]

Thanks Brian, but I think the thread is fine, but we may need to turn down the shoulder on the taps to match the shoulder on the original plug.

Fraser

[scott oz]

Fraser130,

I don’t think turning the shoulder down is going to be the full solution.

While I didn’t measure the depth of the collar around the sump plug I’d estimate it’d be 5mm from the top of the collar to the bottom of the sump.

So even if you turn the shoulder of the valve down, the leaver housing (on/off) I think will foul the collar when you attempt to screw it down.

So you would either need to pack the valve up say 3mmm allowing 2mm for the standard washer. Or grind the colour completely down or a couple mm off so it doesn’t foul the on/off leaver housing after reducing the shoulder of the valve.

As I haven’t removed the sump plug I’ll be interested in the possible solution.

All good fun

[fraser130]

Ahhhh, I see what you mean, Mine haven't arrived yet, but I want to change my oil as soon as it does, so I'll check it out as soon as it arrives, I guess it all comes down to the thread length in the sump, it woul db nice to have the valves' thread level with the inside of the sump (if it's long enough) and use a spacer to drop it down so the valve lever works.
maybe?
I can take my car off the road for a little while to sort it, if I need a spacer, I'll get my mate to make 3.

I guess we'll see.....

Fraser

[fraser130]

Well Scott I'm not impressed!
Not only is the shoulder in the way, but the thread is WAY off!
I've emailed him to see what he can do, Has your plug (on the car) got anything written on it?
Mine says "UNC 4.8"
The thread on the new valve is significantly smaller, I'm guessing here that his sizes are for the V8 maybe???

Fraser:wallbash:

Edit:
Jack at fumoto has been very nice, he's sending me another valve and an adaptor and a postage paid envelope to return the other 2 I bought.
I'll take photos of it installed once it's done so others can see how they fit/protrude.

[reeksyofoz]

So did anyone get anywhere with fumoto drain valves?

I'm thinking of getting one because it looks like i've just pulled all the thread out of a previously bodged sump... :wasntme:the hole that's left behind is 15.7mm :confused:
Pitch on the plug is 1.5

So i'm looking to re-tap the sump and fit a larger size plug, but was going to get one of these valves so I never have a problem with a bloody aluminium sump again!!!!

[scott oz]

I've ground the skirt down on mine but as yet have not attempted to fit it. So I don't know that it will clear the skirt on the sump without the skirt being reduced in height.

The fact that the supplier sent an "extension" which effectively dropped the drain plug down abut 3" which to me makes it unusable for offroad says it all. Also from memory the flats on the extension wouldn't clear the sumps skirt in any event.

Given the above and Fraser130 comments I'd go for the English one as you know it would fit.

[reeksyofoz]

Cheers for that Scott, but the damage means I'm going to be drilling and tapping ... and definitely with a larger pitch so it doesn't happen again ;)

That shoulder on the sump is a pain in the backside though so I'll be looking for an allen head bolt to suit.

If your measurement of 15.7 is correct then your options are to use M18 x 1.5, tap drill 16.5mm; or, use M18 x 2.0, tap drill 16.0mm. I would prefer to stay with the finer pitch.

Yes, that's what I'd worked out, but decided to go for the coarser pitch for a meatier thread... and possibly mill a groove on the bolt for an o-ring.

Finer thread is better if your not heavy handed doing it up :cool:

Course pitch will stress the alloy more and more likely to loosen up...

Listen the Brian! ;)

Just replace the copper washer with a Bonded Washer (also known by brand name "Dowty Washer")

[reeksyofoz]

Turned out that I could only get an M18 X 1.5 anyway :D

[fraser130]

I STILL haven't fitted mine, as I'm waiting for my next oil change!
And Scott is correct, the extension is WAY too long to be of any use..
I might get back to the manufacturer and see if I can get my hands on a valve that hasn't been threaded yet, and if there is enough "meat" on it, get a mate to cut the right thread and shoulder on it, then send Jack a drawing of it so he can offer them specifically for Td5's.
.....one day when I have time!
