Thread: What happened to your D3/D4 today?

Tuesday it finally cried enough. New unit sourced (Denso) and the install will take place tonight.

All done and dusted. Didn’t have the fan tool so it took a little bit to get that bigger off!

Whilst I had it apart I fitted the bling water outlet for good measure

It’s so it doesn’t need bleeding.

Unlucky about the short alt life, I got closer to 220k's on mine. That's one pretty peice of alloy

Common failure point is 120-140k. I was shy 200km

Mind you, I charge 3 batteries, run some serious lighting and spend a lot of time driving at night.

It certainly works for it living.

For a 2 hour job I don’t mind at all.

I got 240k+ (I changed mine preemptively before failure). Mine has no other batteries so I presume the additional load does influence the life of the unit.

HiTombie

Is that water outlet for a D3 or a D4 I know you can get the bling one for A D3 but didn’t think you can get them for the 3 litre sdv6

Same outlet.

Sooo...what gives up on the alt?

I have rebuilt many alts over the years usually for the cost of a couple brushes n bearings and occasionally seals. The electrical side of things are usually good to go albeit I've also replaced regs and diodes on some.

Is it that the flood of chinese units makes it easier to install a newbie rather than refurb like we used to do in the past?

I know my sons just buy the cheapies which seem to go for a while until mud n dust gets them. But I then repair the gen units which cost a k new and keep them for when the cheapies give up ☺

So what fails and why not repair them?
