In this episode we will be covering the install of my hybrid 2JZ to T56 FX300 clutch. This will include running a new line from the master cylinder to the hydraulic throw out bearing, as well as getting the air gap correct between the clutch fingers and the throwout bearing.
Air gap is of utmost importance. Too little gap and your bearing will be riding the clutch at all times... This can lead to clutch slippage and premature bearing failure. Too much gap can be just as bad! If there is too much gap, you can over-throw the maximum length of your hydraulic bearing and blow out the seal. When you do this, you will have to rebuild the bearing, and you'll be removing the transmission to do that.
So, measure twice and install once! The video will cover how to measure the block to clutch finger distance as well as the quicktime bellhousing to bearing distance. Then you will add 3mm of distance to the finger measurements, in this case I had a measurement of 61.5mm from block to clutch fingers. Add 3mm for an ideal bellhousing depth measurement of 64.5mm
For the clutch line, I wanted to eliminate any extra adapters and old fittings and ran a new line direct from the master down to the hydraulic bearing. I sell this clutch line kit on my site, which will work with any 10x1.0mm threaded master cylinder (is300, sc300, MKIV supra). The kit includes a 48" -3an braided line, a 10mm banjo bolt, and a banjo to -3an adapter fitting.
