Heh guys, what sources have people found for the P38 transfer box chain, at sensible money? 500quid is mental!

Have you tried Ashcroft Transmissions?

Their price is listed as £330 just for the part. This still seems extortionate to me, or maybe I'm out of touch.

Just out of curiosity, why do you need one, they rarely fail?

With enough KMs/miles, they all do eventually. It happens earlier to those vehicles driven with a 'binary throttle'...
I was pulling away with a trailer on the back today, and got the 'machine gun fire' as the chained skipped. This happened at 357,500KM (223,500miles), so it's had a good innings.
Not much help but I rebuilt mine around 3 years ago, and went with the Ashcroft chain, there were some cheaper options on the bay, and maybe rimmers? at that time, but although rebuilding the box is easy I wanted peace of mind it would last so decided it was worth the cost of the Ashcroft option.. mines probably getting more abuse than most due to the engine swap and so far it's been fine.

+1.
By the time you look at the morse chain, bearing, new visxous coupling (as that is probably toast by now) you might as well bite the bullet and get a fully refurbed unit off them. Maybe sure they've polished the flange on the output shaft though or it will chew through seals. Some lazy f*cker did a Friday afternoon job on the one I got off them! The rest of it was good though.

I'm not getting a transfer case sent UK>NZ, so if the chain alone doesn't sort it, it could well be end of the line.
NZ? Jeez. That's a hell of a lot of postage for that weight. I'd be looking for a scrapper.
Can you not source a morse chain closer? I don't know the specs but maybe they are online somewhere? Or rind the manufacturer if anyone knows who made the original?

Most transfer boxes seem to use a morse chain.
They do.. just not sure why

I believe 'morse chain' is also known as 'silent chain'. A google of silent chain brings up:
Silent Chain Drives compared with roller chain:
Higher speed and power capacity.
Reduced noise and vibration.
Greater efficiency.
Less velocity variation.
Higher efficiency (as high as 99%)
More uniform wear characteristics.
Longer sprocket life 8. Less affected by chordal action.
