I just realized that this may be the motor that came with the 60A 4 speed. Does it have a shorter main drive gear than the 60A 5 speed?

the input shafts are the same
cranks are the same
pilot bearings are the same

In the photo there is something looks like shouldn't be there

Look at the end of the crank from the side. It may still have the flexplate spacer attached. A lot of automatics came with A15

So check this out. The input shaft on the 4 speed was ground down! I posted the 5 speed input shaft to show the difference in length. This plug comes with an automatic and the PO didn't bother to remove it and altered the 4 speed when he swamped transmissions so it would fit? How do I dig this plug out? I also posted the crankshaft end on the motor I am rebuilding that shows no plug. Looks like the 4-speed will be parted out. Are gears 1-4 interchangeable with the 5 speed? I was told the bell housing is interchangeable. Thanks a bunch DD.

Pilot bush in "Crankshaft4" pic looks to be incorrect and has a step section at the bottom. This would not allow the input shaft to slide in all the way....

yeah kinda looks that way

Which picture is which?

To remove pilot bush, fill with grease, then drive in a tight-fitting dowl. The grease will force the bushing out. Maybe that will work for this "plug" whatever that is. A-series automatic as far as i know has nothing in the crank, but a large spacer fitted over the flange

F4W60L shares parts with FS5W60L. It was basicall a fifth gear added to the four speed which is why it is a dogleg

The 60A version is nearly all changed. The front case (transmission case with bell pattern) is not interchangeable i believe it has three shift rails vs two shift rails

Did a 60A 5spd come in a normal H-pattern ??

DD...no such luck. That plug is pressed in there. Will have to get a machine shop to drill it out. Not sure why this was put in there. Maybe there is a problem with the crankshaft end and they had to cap it?

So the drive gear that is ground down is the 60 series 4 speed. The other drive gear shown is the FS5W60A. The crankshaft end shown with the mirror is the engine being rebuilt and has no plug. A Spridget guy here in the US that rebuilds these transmissions said the bell housings for both 4 and 5 speed 60 series are interchangable??

Before I close out this thread there are a couple of other bolts that I am not sure of. Any idea?

I will start another thread on the 2 types of alternators I have.

60A 5-speed is H-pattern
60L is dogleg

Is the spridget guy Bill? He is the expert

These are the strut-to-steering-knuckle bolts. The washers are for something else

I have no idea why I would have those bolts. Must of just grabbed them from the ground when I pulled the engine. I was hoping these were the intake or exhaust bolts which I need to locate in my pile.

The 4 speed with the modified input shaft is attached. Smooth case transmission. Standard shift pattern. I have a pile of transmissions.....

And the Spridget guy is Will out of Tennessee. His brother may be Bill?? Great company to do business with and yes an expert in Datsun gearboxes.
