Quick update on the 6.5NA 'V-belt 13A' Mitsubishi Pajero alternator swap over to the 170a Nissan GQTD42 kindly Ebay found by @PeeBee ! A special thanks to @matfew and his after hours elecy skills and time too! Mounts all fit perfectly with only one thin washer needed below to align the pulley square. The fun began when we finally realised the new GQTD4.2 oil drain was now hitting the rocker cover. Turned out to be that the vacuum pump castings and bolts are some say 10 degrees rotationally different. Thanks to the kind help also of 'Scooter' at 'Pirtek-Wodonga' on our way through home we have customised a 45 degree M16/1.5T ('JIS -Japanese Hydraulic') new drain to clear the rocker cover finally. The next little challenge became the existing vacuum pump oil feed Banjo bolt would not fit the new M10/1.5T again ('JIS- Japanese Hydraulic') thread. 'Ultimate Fastners' next door kindly gave us a suitable bolt then the lathe and drill press at Pirtek went to work on more customisation. Good news is that they do fit with a bit of tweaking and it's only now needing a descent charge wire and fuse to gain its full potential.
Ooh, and a double special thanks to @matfew for kindly wiring up my revamped winch tonight whilst waiting too ;-)

So you made up two of everything required for modification Mark, 'ol mate????

Was the original drain banjo a different thread?

[matfew]

The patero alt had some imperial threads and gq alt is metric. The vacuum fit straight on oil supply was the m10 and the drain was m16. Not sure on sizing of the pajero one.

Very strange for a pajero (japanese) to be imperial. Unless the conversion company has done some customising.

Noticed the new alternator has 4 mount bolts as well, the mitsu only has 3 so you can swivel the pot orientation 120 deg without issue, but the 4th snookers you, plus the 10 deg thing is a bugger. Anyway, its done, charging ok?

Yep, as Matfew mentioned vac banjo up high fitted no probs, drain banjo on the Nissan was smaller and the new rotation unfortunately wouldn't of allowed it even it was same. The oil feed banjo as you say Matt was very strange for Jap to Jap so maybe was tapped before possibly? Both vac pumps were 3 bolt mounts Phil, it might be the vac case screws seen in the picture. It's running great so far and back up to 14.5/.6 on the multi and Matfew is kindly helping install the additional chunky charge wire with 150amp fuse next week ready for some winching. Matfew has a clamp meter thingo for amp testing so we'll load her up with everything that has a switch and see how it goes.

Alternator rated at 170a, winch will draw more than that, where is the 150a fuse going? Assuming its all running at 12V supply, no doubt less with 24V if you are considering this dual system?
