Stripped Sump ... What to do..

[Cameron_Def]

I went to replace the oil in my Defender (TD5) today, and found I must have been in a hurry or something last time and stripped the sump thread..

Seeing its Alu, I can not weld on a new nut, so I can see i have two options

A. Helicoil
B. Second hand sump
C. A Champaign Cork :)

Anyone got any other suggestions ?

Also, what thread size is the sump bolt ?

Everytime I go to give my baby something, it comes around and kicks me ... she really does not like TLC !


Thanks in advance, I hate seeing my Defender bleeding in the backyard ...

[Cameron_Def]

No one got any suggestions ?

Helicoil.
Best things out for aluminium.

[harry]

helicoil.
repco sell things called recoil, same thing different name.
aluminium lesson- don't pull too hard on the spanner,
but you knew that already!!
second hand sump as a last resort. see hoe you go with re threading it and follow the directions, it's not too hard.

[Cameron_Def]

Thanks guys,

How about the thread size ?

Does anyone know what size I should get ?

[disco_thrasher]

go the champagne cork means every time you change your oil you gotta drink another bottle or 2:D:banana::woot::wallbash:

Sorry can't remember. I know that buying a sump bolt from Land Rover is $34. I had specialty fastners find me a replacement after I dumped the oil all over the super cheap car park. Mate towed me round to have a bolt measured up to replace the sump bolt I had just lost.

[rovercare]

I'd be removing it to rethread it and loc tighting the helicoil in;)

Yeah, and while you're there, remove and locktite the oil pump bolt:o

sorry mate i have looked through all my td5 engine spec books/catalagoue and can't find the sump bolt diameter ,i can find the torque wrench setting for tighnening up a sump drain bolt 15lb/ft

[HangOver]

cant you get stiff like putty specifically for threaded nuts/bolts?

basically paint it on, thread a correct bolt into the hole, leave to dry.
remove the bolt and your done.

I forgot what it's called but you can get it from supercheap for about $15

[97discotdi]

I am not sure of what the sump on a td5 looks like but if there is enough meat around the sump hole and you are not confident with helicoils. sometimes it is easier to take the hole out to the next size thread. Just when you are drilling take care and put grease in the flutes to catch the swarth.:D.
As they always say measure 50 times drill once

[Cameron_Def]

Thanks for all your replys

I can not find a helicoil unless I know the thread size and pitch ... and it seems they are hard to find these days, less and less people are stocking them for some reason!

I will have to scour the net and see if I can find it!! :(

Can you take the sump plug to a bolt place? Those guys are experts at working out what you need.

It might be wise to remove the sump as you have to drill and tap the hole which might spray some swarf around :o

yep, it's easy enough. Measure the OD then use a screw pitch gauge to measure the pitch. Handy little tool, and one a bolt supplier will have.

FWIW I've had one forever, and you'd be amazed how often it gets used.

[Cameron_Def]

Yeah the sump has been removed and the bolt is on my desk..

I will see how I got today if I get time to get to a bolt place!

[Pedro_The_Swift]

You may have trouble with a sump plug as it is so short but FWIW...
the easiest way (edit/if you don't have an guage) to get an accurate pitch measurement is to count ten threads (or more for that matter if you can) and take your measurement, then divide the meaurement by the thread count. So if ten threads measure 17.5mm it's a 1.75mm pitch, geddit?
Takes most of the guesswork out of measuring fractions of a millimeter (or inch) and A LOT easier on your eyes (yes I'm just hitting that age now:mad:)

[Rovernaut]

after I dumped the oil all over the super cheap car park. :o
I normally wait to do my oil changes at home:D

[QSDT]

Could look at something called "Seal-lock thread repair" much cheaper than recoil. All you need is a drill and a spanner. Work well I've used them a few times.

[HAK]

wouldnt it be easier to replace the samp rather then redrilling and getting shaving in side the motor :eek:

[rick130]

errr, it's a cast alloy sump so isn't cheap, and he's already removed it so if it's cleaned afterwards, no swarf in the engine. ;)

I have removed the sump .. so there is no issue with shavings etc.

Helicoil KIT from CBC = 118 plus gst ... no one else but CBC has it, or would get it, I tried over 15 places today, plus 5 phone calls.

Second hand Sump from TR Spares was $220

Its a tuff call with the spare sump vrs Helicoil .. but with the Helicoil I get a thread that will be HARDER to strip again ... and a tool I will put on here for lend for others who 'Stuff' it up like I did.. thus saving other people dollars !!

[ciapek]

I had the same problem on mine, my solution was a little easier on the wallet as we have a Helicoil kit at work, so I did a loaner, and only had to buy the actual coil from a local bolt place..Cheap from memory, only a couple of dollars at best.....
I still have to use a little gasket sealant on the thread between oil changes as it used to weep a few drops of oil, especially after going to Synthetic Oil....
Perhaps try one of the Hire places, like Coates, you should be able to hire a kit rather than buy it......
Worst case scenario try a LR workshop seeing that you have the sump off allready, it would not amount to much labour to get the coil fitted in.....and if and it probably will weep oil, you can hit them up for dodgy work......:eek:

[PLR]

G`day Cameron

If you`ve not found the size , my parts CD says all TD5 Def/Disc have the same plug . if that helps .

Also try an engineering workshop for a helicoil fitting

The coils themselves are cheap it`s the tap and tool that cost and maybe 15 or 20 minutes labour if they take there time .

Just an option .

Cheers

Seal lock Australia Ph:1300 880 304. Most likely would be less than $30 and easy to use.

If you have the sump off, what is the problem? Just drill and tap the outlet hole oversize and use a cap screw with a nylon washer for a gasket and loctite sealant on the thread. You could possibly, depending on accessibility, have done this with the sump in place by smearing the drill and tap liberally with grease to hold the swarf, and with a depth stop on the drill so it just penetrated and no more.

Yeah or you could just dump the tcpip stack to stop BSOD and disallow all external UMC packets to eth01 making sure that all external traffic is restricted, then adding a non response marker to the IP stack allows external hosts no longer to see if anything on that external IP address.

You see .. we all have our own skills, I know how to design, maintain and secure firewalls, do you ?

Technically I am good and messing with mechanical things, but its not my skill set... thus why asking for advice on here!

Thats 'the problem' ;-)


Sorry if it sounds rude... its not meant to be!!!, but not all of us on here are mechanically minded, and live in grease, some are even new to LR ... its sometimes a tad scarey!

That is what you got. The advice.

Mate, having striped the odd sump-plug in my time (ah the heady days of apprenticeship!) the best bet is to go to another size plug. I've used HT bolts as sump-plugs on holdens when nothing else was available, no worries! If you use a bolt your problem is going to be getting a washer to fit - if in doubt use teflon tape - when you get to the bolt head, twist the tape a couple of times (into like a cord) then do a few laps under the bolt head - this effectively makes a "gasket" under the head and works fine. Having said all that, I would only do it to get out of trouble - if you've got the sump off you might as well do it properly!

Take your current plug to a bolt & nut guy and get them to give you 1/2 a size up (if possible), if not then go one full size. Get the drill and tap from the same place - just make sure when you drill you follow the same angle as the old hole. Finding the right size fibre washer will be tougher, but any good repco should have an assortment of sizes.

Option 2 is to take it to your local workshop and get them to do it for you - should't cost more that 100 bucks for the whole shebang.

Use this stuff.

It's absolutly brill for stripped threads in aluminium castings like sumps, water pumps etc.
You'd have to remove the sump and block the hole from the inside....fill the sump plug hole with the weld...insert the original sump bolt and the jobs a goodun'.
I've been using that stuff for the past two years to do just that.

It's also much stronger/harder than aluminium so the chances of stripping it again are much less.
