    HJ61 24v alternator replacements?

    I expect that is the HXA004 that’s available on one or two OZ eBay sites. The specs match up.

    HJ61 24v alternator replacements?

    That’s a fair option if you can find someone to do it. Also the knowledge to increase the output of the the standard alternator from 30A to 60A by using a stator from a 12v unit seems to have been lost. Once the carrot of 60A plus gets dangled it’s hard to resist. Power needs have changed...

    I hope these are useful. They come from the The NAPA catalogue

    HJ61 24v alternator replacements?

    Other options if you are okay with grinding and cutting the foot length. Need to add an external vacuum pump with these ones.

    HJ61 24v alternator replacements?

    The HXA041 has a foot to foot length of 81mm compared to the 12HT 105mm. Other measurements such at the Adjustment hole to Pivot hole is correct at 175mm and a shaft diameter of 17mm meaning the 12HT pulley will swap over. https://www.ebay.com.au/itm/254624247731? Internal regulator.

    HJ61 24v alternator replacements?

    The HXA004 is also from an old vehicle (Nissan SD22) and may be difficult to obtain. Be careful in choosing to make sure you get the 50cc vacuum pump, not the 30cc vacuum pump in other similar models. New OEX Alternator Regulator 24V - External To Suit Hitachi #RGX4026 | eBay -...

    HJ61 24v alternator replacements?

    Resurrecting this discussion to keep it all together. Assuming the 12HT runs the same alternator as a 2H, the OEX HXA027 contains the physical specs we need to match. This is the 12v version, but it gives us the specs we can match 24v units Foot to foot 105mm Adj hole to pivot hole...

    A few 12ht dyno graphs

    Thanks for posting it too. I’ve had a similar journey of performance improvements (exhaust GTurbo and PDI) but haven’t yet gone with the plus 30’s and pump reworked. That was by ADS in Mareeba I guess? it’s nice to see the data and it matches the seat of the pants feel.

    RTH: GTurbo got lazy after highway drive, slow to build boost, lower boost levels than normal

    Did you hear the waste gate disc clack shut when you released the air? Your own curiosity won't be satisfied until you remove the dump pipe and check things, but it would seem to me that the waste gate is working as expected if boost did not creep up to 22psi after you reconnected the actuator...

    RTH: GTurbo got lazy after highway drive, slow to build boost, lower boost levels than normal

    Might be nothing to do with the turbo. What about changing the fuel filter? Less fuel will affect performance a great deal.

    Builds building a landcruiser for overland expedition

    New Year good wishes to you. It's been a while since I've checked out how your project is going. I cannot recall if you fitted a GTurbo along the way. I'm just thinking that if you haven't it could resolve your power situation without having to go to the expense of changing gear ratios. You'd...

    12HT Engine noise after overhauling and its checklist

    Direct injection, 12ht, is always noisier than indirect injection, 2h. But yes, what was the outcome?

    12ht overboost light intermittent

    The over boost light is set to come on at 1 bar, 14.5psi. There is good reason for this; the compressor wheels break at much over this
