Filler plugs on gear and transfer box.

[siweb]

They wont bloody move even with a 2 foot breaker bar, daren't get a bigger bar on it in case something gives other than then plug 8O

Any ideas before a find another way to fill em up :?:

SPRAY ALOT OF WD40 OR TRY SOME HEAT

 

[ronypony]

yeh if you can get some directed heat on the plug (one of those cheap butane blow lamps from B&Q should do the job...They will be off in jig time. Heat em up good !

I had the same problem i just drove around for half an hour to warm the gear box up and they came out OK.
good luck.

 

[(RIP) PLANK]

sprokit has good advice make sure the oild is up to temperature.

look on the bright side, aren't you glad you didn't take the drain plug out first :wink:

 

[siweb]

Ty guys,, forgot to say did try the heat job it not worked, (maybe didn't get it hot enough)

I did do the dran plugs 1st :lol: as the car is sat in the garage having a full fettle ready for june 1st...

Filled gearbox up through gear stick and transfer through one of the switches on the side :wink:

 

[(RIP) PLANK]

well there's nothing like experience, :lol: :wink:

at least the boxes had a good draining time!

filler plugs

have you heard of that freeze release made by comma,apparantly you give any seized nut or bolt a good spray and it shrinks the nut and bolt away from the rust that holds it and bobs your uncle it comes loose.well thats what it says on the can,just need an excuse to try some.got a new exhaust system to fit so i might give it a go :smile:

i have used the pipe freezing stuff a few times for plumbing, gives you a 15 minute plug of ice to do a quick fix. 15 mins unless some tool runs the hot tap in the room next door, yes thats what happened to me :lol:

After looking through the PDF manaul thats listed on here somewhere is says Oil capacity is 3.6L and thats for a 2002 model but after reading on the forums is say after 98 it's 5L :?

I had another go today at the filler plug, heated up with blow gun for 2 mins (not sure really hot enough) put the breaker on and a bar on that and still the plug not move and the bar was starting to flex 8O why the ******* is it so stuck :?:

(to add comma oils website says 3.5L)

Hmmmm that is suspect..I have loosened completely rusted on spring hanger bolts etc using 'heat'..never had one that did not give eventually..theres no way that a filler plug should be giving you so much grief...is it the same for both the gear and trans boxes ?

I dont want to patronise but you are trying to loosen the nut and not inadvertantly tightening it by mistake...I have done this myself in the past..

Sometimes I actually attempt to tighten a stubborn nut/bolt before attempting to loosen it. Give the breaker bar a few sharp hits with a heavy hammer..sometimes this can shock the nut /bolt breaking any corrosion that might be the cause of stubborness..

I'll second that a sudden shock often breaks the rust far more effectively than swinging on it with a long bar, much like an impact gun really.

I suspect foul play! many manufacturers now specify a sealant for the threads of the plugs, when you buy the 'real thing' from the dealer it turns out to be a sort of coppaslip stuff, but many people without reference just thread lock them in, and many modern thred locking compounds are awsome, they virtualy weld the metal in place. I have some that we tsted by sticking two 12mm nuts together with and they wouldnt come a part without a hammer! im trying to remember the name of it, it is often sent in a little blitsr pack with some parts you order. 'tough lock' or soething like that.

maybe this is the case at its last service? I could be a strippped thread having been chemical metaled back as i have also come across that, but with both plugs so tight i suspect the thread lock , having said all that, if you have drained and refilled, do you really need to get them out? the oil in the boxes doesnt need changing very often and you may do more harm than good keep trying.

sounds lazy i know, but maybe they are best left?

Hi PLANK, I just don't like been beat :lol: :lol:
But :!: after close inspection a can see what looks like a sealant of some sort around the edges of the plugs (yes both boxes are the same)
I had a go at the hammer but as you know not much room around the gearbox to swing owt :lol:

But your probably right m8 it's not like they need new oil often, I just wanted to check I got the right amount of oil in it :roll:

 

[(RIP) PLANK]

if you read a few threads here i has been recomended to add a little extra oil to the gear box to save wear in one of the bearings, look up our molyslip supplier its good stufff and might make you feel better knowing you have done your best!

Just to add siweb, if your filler level plug in the gearbox is on the near side (left hand) then the oil capacity is 3.5ltrs, although I would suggest fitting 4ltrs, if its on the off side (right hand) then it will be 5ltrs.

If a thread lock has been used on the plugs heat will normally break it down making it soft.

 

[(RIP) PLANK]

some of thes new thread lock compunds are more like super glue and take some shifting once they are stuck! on the bright side they are good for all sorts of tricks :wink: like gluing plugs back in when you have stripped the threads :lol:

With reference to sealant, I often use calor-tite, a sealing compound for gas pipes, but it is also suitable for sump plugs, etc and water pipes (not drinking water connections).
It is similar to red hematite, and never goes hard and cleans off with meths.
You can buy it from caravan dealers or boat chandleries.
All the joints I have used it on come apart cleanly with no corrosion as it also keeps the damp out.
Worth keeping in your tool box.
This product is not a locking agent so don't use it for that, it is only a sealant.
