MKIV SUPRA Auto to Manual Swap (version 2) - Part 5 - Index Bellhousing, Runout check

In part five of the auto to manual Magnum-F GR700 kit install we are covering how to check runout, and index the bellhousing.

This is one of the most important steps of this install, and I include this index plate with all of my kits now just because I want you guys to have the best possible experience with this transmission kit.

The quicktime bells are supposed to be in spec, but it is always good practice to check them to make sure you are not out. If you have ever had motor work done, like a line bore for billet main caps, it can shift the crank UP in the block, which alone can take you out of center from factory spec.

An off center or "out of index" bellhousing will cause premature wear on the input bearing, the input gear, and will shorten the life of your transmission. This can also cause shifting issues, extra noise, and you can make installing the transmission onto the clutch a real pain in the ass.

I tried to make this video as in-depth as possible, so it is a bit long... but I highly recommend following my procedures and recommendations. If you do need to use the offset dowels, i recommend soaking your OEM dowels in penetrating oil overnight and letting them sit before attempting to remove them.
