Hi all, I have a 1983 HJ60 (2h engine with the 5 speed manual). Over the weekend whilst towing my 1 tonne boat I noticed the revs rise as I was accelerating up a hill and the car was slowing down (in fourth gear). Clutch slip I assume....
I had a similar problem happen on the way home from work while I wasn't towing..
I am now looking at clutch kits, and have seen them on eBay at about $260 delivered for an Excedy kit. They have also got Excedy heavy duty clutches, and Excedy Safari Tuff clutches for about $380 - over $400....
Would the standard Excedy be fine in a car with no mods, that tows rarely, and us used as a daily driver - I really don't want a horribly heavy clutch, but I don't want slip either!
What else should I do while I am there? Rear main engine seal, gearbox input shaft, oil pan gasket, clutch slave cylinder are all suggestions I have had so far...
Are there other clutch brands people would recommend, or is Excedy good????
Thanks heaps
Drew

Drew,
I had my 1Hzz clutch changed with the standard Exedy Clutch, it cost $340 from Superstop. The specialist differential, gearbox mechanic reckoned the std Exedy would have a better surface area grip than the original, and a heavy duty was not required. I had smoked up the original clutch a couple of times while towing and in heavy sand. It never slipped after that, but it was changed because the throwout bearing was squealing after 18yrs. (seized). They did the transfer case seals and machined the flywheel.
I have done a fair bit of heavy towing since, it works well and is not heavy.

Cheers,

Bill

Thanks Bill - that is what I am wanting to hear re the Exedy clutch.... Interestingly there was no smoke evident, or smell, when it did slip - hopefully it was the clutch, but I can't think of anything else that it could be!

With 77kw when it was new and most of them gone now, that doesn't even happen on the sand.....

The Exedy std clutch will be fine the heavy duty will be tough changing gears all the time

I've got the Exedy heavy duty in mine behind a 1HD-FT engine driving into a H150F gearbox. I tow a van of around 2800 kg. I don't do a lot of hard 4WDing these days but it gets a pretty good workout on the beach at times. No problems so far. Gear changes all good.
I wouldn't go for the ceramic disc extra heavy duty (Safari???) version unless you are thinking hill climbing gymkhana type use. Even the guy who sold it to me said they are a bit savage for every day use.
