Says brand new. Send them a question about dimensions. I dont know how they compare with the BD supplied unit.

If they are the same length, getting hold of winnies unit or perhaps any of the TD42 alternator/pumps should tell you if it will fit. Going off your shots previously you seem to have a fair bit of room

Might still have to take @Winnie up on his kind offer to borrow his old one for mock up fitting tests. When my truck was up at Millweld we held an old rusty one over the top and found the mounts pictured below were same. The issue appears to be the vac pump pictured below being very close to cylinder #1 intake manifold as from memory the Nissan one looked closer than the existing Mitsubishi in now.

No worries mate. I need to come up your way at some stage to grab some doors off Rossco, I'll let you know when I'll be around

Hey markie, I've got my old standard alternator in the shed. If it's any help it's yours.

That alternator looks like an absolute beast BTW . .

Cheers Rossco, is it a GQ TD42 with vac pump rear mounted mate?

[Rossco]

Yep that the one. .

Are you still thinking of the 170a unit as an aux. or replacement? If replacement then cable size and maybe the front mount plates might be all you need to play with - BD absolutely dont use the nissan unit, they told me that and I think its a mistake to be honest. This upgraded unit has capacity upgrades in amps and vac, so win win. The monster one is a beauty and certainly will benefit when winching.

Yep, replacement mate. Then look at an aux down the track as backup. Reckon even the 170a will be working hard with 6hp motor + twin 19a thermos + lights etc.... 170a is a lot to ask of a TD42 alt :-)

I bought a Uniwelder many years ago and it was rated at 200a 100% duty cycle as it was powering a welder as well as the vehicle alternator. i was told that automotive alternators are duty rated at max amps for corca 5%, so its understandable why they struggle under the load of a winch. The 200a unit I have is 100% duty rated for just that reason.
