Given the "PERFORMANCE" in the casting they could well be an old discontinued model from Performance Alloy Wheels in Australia. 

100% aussie performance wheel - my wagon came with exactly the same wheels.

Anyone here removed/replaced a ring gear on a flexplate before?

Mines got fucked teeth, I bought a replacement that's not quite right for the trans, wondering about heating/ flipping the original ring round to the 'fresh' side. Next option is repair shop, but too impatient to wait till next year etc

Why heating? Is it not welded to the flex plate?

Should be ok as long as you get it in the same position relative to the starter. Check if there are any tapers in the edge if the teeth that help starter engagement, but usually they would be on the starter, not the ring gear.

Chur. Heat to swell the ring gear and loosen death grip. Yeah this old one isn't welded or riveted, but I'm a little sus as I can only find worthwhile info on flywheel ring removal, not flexplate

You might even try dry ice on the flexplate while you heat up the ring gear. Normally you would cut a worn one off, and idk I feel a flex plate would be more prone to warping if you heat it too much too.

Yep I've done that before. 

I'm not sure what the "correct" procedure is but just made it up and it worked. 

Grind off any welds and hose it down to cool. 

Get the oxy torch out on hot af and do a few hot laps of the ring. 

Tappy Tappy it off with the flex plate sitting on a block or similar. 

Plate in freezer overnight. 

Get the ring warm with oxy again, slide it onto the flex plate and live the smooth starting dream.

...so long as you get it square . 

 

Weeble wobble occasional crank for different reasons otherwise. 

I'm sure that won't be a issue given Steelies is a bleedin engineer innit but just thought I'd voice it as a consideration.

I've done one on a flex.plate. but I've flipped them on flywheels before. No heat required to get them Off. Just a fat pin punch and a heavy hammer. They go back on easier with a bit of encouragement from the hissing spanner.

Dayum, ring gear would not budge. Some dimensions changed lol, but zero slip. Some evidence suggests presence of hidden magic.. No factory rivets or external welds, but wee globules that look like friction weld type scenario, or something. Anyway, project stall till flywheel place opens

Any one here know how to connect motorised gates. I installed gates here last year but get a bit lost trying to get the 3 different wiring diagrams to work to gather.

Hit up @shizzl

I did a little while back. He used a contractor to do the electrical work. 

@shizzl could you give me the number of the guy you used in auckland?

@Mr Vapour, the guy I was using at my last job turned out to be a useless prick..Wouldn't turn up etc.

 

Are they all connected to power and you just need them to work off a single remote?

My last job I did in auckland was 3 automated gates on one property..I installed all the automation myself and had them running off a single remote (6 remotes in total for the household).

Pm me if you need any help

Post the wiring diagrams? And what you are wanting to achieve? Could be a house DIY topic, but keen to see what is involved.

Any idea where I can get something like these in NZ that are rated for a die grinder speed (1/4 shank) and the sanding drums?

@Truenotch?

 

 

PPS industries bring in the best ones (Pferd) and they sell direct. You could also try Tradezone or Twiggs in Welly. 

I personally rate rolled cones way above the cylindrical versions. They last way longer as there’s loads of layers to get through and they’re smaller diameter, so won’t fly apart as easily.
