Title: Tractor Glow Plugs
Post by: Pitchfork on 25 January 2008, 15:01:16
a) How can you test them?
b) If they need replacing should it be genuine Bosch or are pattrn ones just as good?
c) Should all 6 be replaced at the same time?
d) Where is a good source of them?

Not worked on the Omega Diesel, but used the following link
to check out my Merc Diesel plugs. Although your system
won't be the same, the principle should be the same. So just
identify your components and use the link as your starter
for ten.

In answer to your other questions, I would use original manufacturers
equipment and replace all 6. If 1 has gone, the others won't be far
behind, so you don't want to keep repeating the work 6 times until
they're all changed.

Hope this helps.

Hiya, I replaced all 6 of mine last year after it used to take ages to start in the winter - not sure about testing them, i just bit the bullet and went for it.

Got them through Halfords Trade, Genuine Bosch ones, worked out at about £30 iirc.

Unless there is a way of testing them and identifying just 1 faulty one to replace, I would replace the lot considering what little they cost.

Anyone in my vicinity with the ability to purchase 'Trade' or do I have to pay full price? :'(

I think my Halfords TC card has just expired, sadly :'(

Lent it to a mate in about June too, IIRC, and forgot ::)

If you have any sort of mechanical knowledge you should be able to blag one out of them. They ask for a engineering qualification or evidence of being in the trade - but it was never really enforced when i worked there.

IIRC they don't expire... I have had mine since they first introduced it, never been rejected yet  :y

They might have changed this since the early days though? :-/

OK. I'll ask for it back and try it then. :y

Back in the mid 60's I worked for Halfords in Southampton (Saturdays & Holidays) - the days of staff wearing green nylon jackets!
Don't suppose that qualifies me for any concessions now though? ::)

You should be able to test them.........tho i believe on a TD is a pita..........if you have a multimeter......they should read 3 to 4 ohms...connect to one end on the glow plug and other to earth......if they read open circuit.....they are knackered  :y

Just shove 12v across them whilst holding the element. If your eyes water, they're working ;D ;D

all i do is grip the body of the glowplug with a jump lead connected to the neg terminal, and touch the pos terminal with the "wire"end of the glowplug. it should glow red hot within 5,6 seconds or so.

much the same as james's reply but wthout the pain.

iirc, should measure a shade under 1 ohm.

change all 6, as they are a bugger to change, as in true BMW style, all the bloody inlet has to come off. Officially, that means you should change the 6 inlet gaskets as well, though every time I've ordered them, its taken dealer weeks to get them, as have to come from beemer.

As most diesels really, don't break them off in the head removing or you'll be knackered. Perhaps a good bit of penetrating fluid first  :y

Sounds a bit low to me.........dunno on omega tractors......but under an ohm...is a massive current for the battery to maintain all 6 glow plugs........even for 5 secs or so  :-/

Remember you are testing them cold. Resistance rises as they heat up. 1 ohm gives 12 amps ish peak current which then tails off as they heat up. I reckon that's not far off.

Either way, best to check on a battery in case they go open circuit when they get hot.

I didn't know you were supposed to take the inlet off? I did mine with it still on, was very tight, but do-able.

Suprised you managed to get a spanner around the injectors and fuel pipes.  I reckon even a Tunnie would struggle with that one...

If its alot better with the manifold off, then I would recommend that! If you leave it on, it involves a deep socket and alot of knuckle joints and extensions from a 1/4" set. Took me a morning to do - the central 2 were horrendous. :(

Takes me about 30mins to do all 6...

Oh ok... my way was defiantely the hard way then...
Shouldn't have to do them again for a while though - hopefully.
