So, I tried a search for this and after 6 pages i really came up with nothing.
 
I am swapping a 60A trans into my 1200 and almost all of the questions have been answered but one.  On the A14 motor that this trans came off of, there is a plate that goes inbetween the block and trans and it is about "1/8 thick.  On the 1200, there is just a thin dust plate that attaches to the front of the bellhousing and covers below where the block meets the bellhousing/ trans.  Both transmissions measure out to be the same length.  Once I had the original trans out of the 1200 i was thinking about using the thin dustshield that was matched to the 56 trans because it appears that some of the holes have been made larger in order for it to mount to the 60A.
 
Anyone have any ideas about this or possibly have run across this before?

The plate on the left side matches to the 56 4spd and the one on the right matches to the 60A 5spd.

As long as that bottom dust shield does not interfere with the 1/8" engine/trans plate it should be fine.

so, looks like use the thin dust plate, A12 flywheel, and short t/o collar.....Thanks.

 

 

 

Which is good because I didn't want to change ALL that shit around.  Also could not remember what it all looked like when I took it apart back in '11 or '12.

sometimes you have to massage the side of the tranny tunnel for a sender clearance 

and you have to modify or make a trans cross member

Both of my coupes started life as autotrajics (at least that is my story and I'm sticking to it) so larger tunnel. The 60 series trans has a mounting point farther back on the tail case that I think is for a different type bracket

(stabilizer of sorts if you will) and this lines up very well with the body mount points.  The 56 series trans was installed by PO and pretty much had a U bolt over the top or the case and into the bracket that

holds the mount.  It was quite redneckian if I do say so myself.  Forgot to take an oic of it, so maybe later.  Trans was stabbed this morning and now just putting everything back together.

Excellent info! I'm about to do this upgrade and I had no clue about the flex plate or what T/O bearing was used :thumbup:

Had to leave for a couple days and was not able to complete this.  Hoping to button it up in the next few days and will post the results (success or failure).

I'm hoping for success.

 

Are you using the stock 1200 clutch or A14 or ??

Stock 1200 clutch.

 

Here is some curious info....from a Nissan quick reference book that I used in the late '80's.

1200 clutch disc: 30100-H8900

B210 clutch disc:

4spd 30100-H8900

5spd 30100-K0500

210 clutch disc: 30100-H8900

I did not look in the actual catalog that I have to verify, but I think something is screwy with the 210 listing.  It seems they should list a 4 and a 5spd clutch like the B210.

 

FWIW, the 5 spd I am using is out of a 210.

Kelmo,

Right now I have a stock 60A 5 speed (non dog-leg) in my race coupe. When I went to the A15 I was still using the 56 series close ratio 4 speeds but as is well documented they have issues behind the larger engine. The motor uses a 14lb A12 flywheel, I'm using a standard A12 clutch disc with a 550kg pressure plate. I mix and match clutch discs based on thickness, over the last 30 years I've simply gone though my box of used clutch discs and install the best one. While I'll admit it's a bit hillbilly I've also never had a failure. Granted it's a race car the miles are low and I take off from a standstill very gently.

This summer (off season here in Vegas) I'll be going through the tranny as it's got quite a few miles on it (came out of a 140,000 mile street car). The rear seal is barely leaking so the flywheel needs to come off, at that time I may remove the engine plate to shed the few extra pounds fortunately I have both style of throughout bearings.

Tom

So, life finally slowed down a bit so that I could continue this project.  Almost all buttoned up, got the clutch hydraulics bled this AM and adjusted the slave push rod.  Have good freeplay on the clutch pedal but no freeplay on the clutch operating arm that is pushed by the slave and in turn presses the release bearing onto the pressure plate.  It seems to me that I should have a bit of freeplay there.  Not having a little movement where the arm meets the slave push rod makes me think the release bearing is resting on the pressure plate tines.  I have left a slight amount of freeplay between the slave push rod and the sport where it (push rod) connects to the operating arm.

 

Here is me hoping I don't have to take this apart again.

If you pull the clutch slave cylinder and you can't wiggle the clutch fork at all it will need to come apart. You don't need a lot,of play but there should be at least a millimeter or so. It may take a little effort to move the fork but you should be able to wiggle it. If not you'll need to pull it apart. It'll need the shorter throw out carrier or the engine plate that spaces the tranny back a few millimeters.

Well poop, pretty sure I used the shorter t/o carrier so it sounds like I will need the plate that goes between block and trans.

 

 

 

 

05/12/17 edit: Took the lock nuts loose on the slave cyl push rod and am able to get movement. Pretty effing happy about that as I REALLY don't have the time to take it apart and reassemble again.

 

Thanks for the help ya'll.

I've had to readjust the slave push rod a couple of times. Sometimes as little as half a turn on the adjuster nut is all it takes.

So I adjusted the slave cylinder and have no friction point when depressing/releasing the clutch pedal.......in other words, the clutch is not engaging.  I am thinking I need to use the long T/O collar to make this work properly.

 

Current setup:

A12 clutch and flywheel

short T/O collar

210 slave cyl

60A trans

 

Pulled 3 transmissions off the rack yesterday, not a one had the T/O collar.....what the hell did I do with em.

Dang. Sorry Kelmo. Apparently that long bearing collar is uber rare. One way to fix it is shim the pivot point for the fork out a bit. I'll edit my post to include the long bearing collar.

Well, I am sure I have at least 2 of them somewhere in the shop.........somewhere.

 

Going to take another swing at this and see what happens.  At the very least I can get the process down with a step by step recording of what I do. And maybe I will do a write up here.

 

 

 

 

 

But don't hold your breath.

 

 

 

4 Datsuns and not a one of them I can drive :poop:.
