It's a Datsun thrust bearing on a machined celica carrier. Then datsun clutch/pressure plate with celica splines. Best thing I ever did what just have the datsun flywheel drilled to suit the 200mm celica pressure plate. Now its just all off the shelf toyota with much better clamping force than the other setup.

Spark is strong when its there. Hold the lead back from the plug and you can see it jumping and you can also see it stop jumping as it stutters.

I've got a S2 bluebird electronic distributor in the A15 and of late when starting from cold it just loses spark even if holding idle at 2000rpm it just dies. I was watching the spark today with the lead pulled back and as it stutters you can see there is no spark. Soon as it warms up this problem seems to disappear. Also you can see the tacho bounce when its playing up.

Im wondering is it possibly the ignition module is dodgy or the guts of the distributor?

I had a similar issue with my celica 5 speed behind an A-series although cable clutch. Pedal take up point came out further and further but still was not slipping. Adjusted the cable lasted a day or to before it pretty much let go all together. Slipping badly. Pulled it out to find the diaphram buggered.

Awesome. Cheers Steve

Just wondering if anybody has come across a 90 speedo drive adapter that suits datsun/toyota boxes. If so any idea which models would be worth chasing at the wreckers or even and repco or the likes.

Cheers

Pulled it all back out again today expecting to find something obvious, but no, all looks good. Throwout bearing feels good. Spigot is good and the wear on the pressure plate fingers shows no signs of rubbing.

Anyone got anymore ideas? Im going to call the clutch place tomorrow to see if they have experienced this before. Possible faulty pressure plate? Im at a loss.

Greased. Brand new everything + machined and definitely adjusted properly.

Just installed a new clutch in front of the celica 5 speed. I sent the flywheel, old 180mm clutch + pressure plate and carrier with the throwout bearing to the clutch shop to be redrilled to suit a full toyota 200mm unit. It came back to me with a new throwout bearing which I was suprised to see was the same as the old one to suit the smaller clutch. Also installed a new spigot bearing from dellow. I also measured the heights and the new p/plate is the same height as the old.

Anyway, for the last 300kms the clucth has felt great. All of a sudden the pedal became slighty stiffer and you can hear a little whirr with the clutch engaged. No vibration and the clutch still engages/disengages fine, albeit stiff, but certaily doesn't feel right. Turn the engine off and the pedal goes back to feeling completely normal.

Any ideas guys? Possibly incorrect throwout, all though first 300kms were 100% normal or could the spigot be binding slightly?

I'd be keen in a month or so.
