Woudn't start the other day. I pulled the connector. I have 3 failed plugs.
Anyone know which pin matches which cylinder.

Some are easier to change than others.

Last time I couldn't get the manifold off the studs.
Thanks

do you mean which pin from the wiring goes to each glowplug??

afaik they all just wire up the same - there is no specific order with the wiring

[platty]

I changed mine with the inlet still in place - had a few bad ones but changed them all for peace of mind.

Change all of them & avoid the cheap ones on e-bay
Beru are the OEM manufacturer circa £11 ea
Wired in parallel so any lead to any plug

[osealy]

Yes! there are six pins on the connector 3 are dead. Are you sure about the parrallel bit?
And I had already ordered some ebay ones . Wellman 20£

They are individually wired from glow plug to glow plug relay, where they are all joined in parallel, if that makes sense.

I have 5 out of 6 faulty glow plugs, but can't face changing them in this weather

I'm surprised you can start at all with 5 down. I had to crank for ages this pm 2Deg.
Do you know which pin is which plug. I'm hoping the dead ones are the easier. I also don't fancy changing 6 in this weather.

[ngrainqey]

get them all changed, you know you want to
saves time in the long run anyway as you'll have changed them all so none should go any time soon

[Pitchfork]

Once one goes the rest soon follow in sympathy!

[osealy]

The pin order is 123789 so now I need to find which are dead. I think 3 is the easiest to get at.

It's obviously that time of year. -3 deg when I left work this evening and the tractor just wouldn't start. I'm sure it's the glowplugs.
Anyone done this job? They appear to be very difficult to get at with a manifold above them. Do I need to remove this?

[osealy]

It's very awkward especially if they break. & see plattys post.

Yep - inlet manifold needs to come off .... !

Once it's removed, stuff some rags in the inlet ports on the cylinder head to prevent any foreign bodies entering the combustion chambers while your changing the plugs.
