Aisin's site does not list a part number for the 60 series, only the 62 3F, not 3FE series, I assume for the 62 series non-autos in other parts of the world. I wonder, would a clutch listed for a 62 3F fit behind a 62 with 3FE with a 60 series flywheel? What standard transmissions were sold behind the 62 series in other parts of the world? H55, H42.
This would be an option, but I wonder at what cost and if it is much better than Marvin's.
What can people tell me about pressure plate pressure? I assume more is better, up to a point.
Marvin Crawlers is a Heavy Duty kit that features a 1,200 ft-lb pressure plate, which is a step up from the stock clutch, which is rated 900 ft-lb.

That chart is for Aussie or General European models.
USA part # cross to '84 - 87 Aussie FJ62s MTMs which should be the 5 spd w/3F engine.
USA OE part # 31210-60070 (60071 sub) PP
and 31250-36340 for the disc.

Dunno .
Google turns up zilch.
May have to contact Aisin/Asco to see if it's distributed in the USA yet... Or SOR might know, they sell a lot of Aisin aftermarket.

I have not heard Centerforce mentioned. Is there a reason for that. The one below is off Man-a-Fre's site.

Would also like to hear opinions on the centerforce clutches...

No, the rubber dampers are far better. They do not fail. The steel springs will fatigue over time (esp. w/ heavy use), then they shatter and the shards of spring are slung outwards into the workings of the PP.

Sorry, no opinion.
Centerforce clutches are CF assisted, so the harder they are revved, the tighter they grip. Behind a turbocharged engine, or a staged nitrous system they are ideal, because as the RPM climbs, the crankshaft tork climbs and the clamping force climbs. A 2F makes peak torque at 2000RPM, while theCF assist doesn't do much until higher RPM.

That is what I thought about the Centerforce, not enough RPM to take advantage of the centrifical forces from a low RPM Landcruiser I6. And they're not cheap...
Interesting take on the rubber dampers vs the spring ones. Anyone else have an opinion of this? Has anyone ever experienced a spring failing?

Wouldn't the rubber harden and crack over time? I too would have figured the springs would last longer in a clutch for our applications.

Again, not an opinion, just a statistic. Never seen a rubber damped disc fail on any stock vehicle, seen plenty of sprung hubs fail, shedding the springs which lock the release fingers on the diaphragm.

Maybe a little, but it doesn't seem to effect function.
Cool. This was the first time I'd ever heard about using rubber dampers in a clutch. I'll have to keep that in mind.
Good to know. Learn something new everyday! I was thinking of ordering one because I have heard good things about the company but that information helped me understand that it is not worth the extra coin! ThanksSorry, no opinion.
