Basically spent the whole day wrestling with my gearbox, now have badly bruised shoulders and my pride a little dented lol.
I have an R33 GTR, I've upgraded to a HKS triple plate (pull type) clutch, I can get the box spline into the plates but no further, it's just won't go.
As it is, I have it with ring on the release bearing towards the gearbox/pressure plate hence only one plate between pressure plate and ring on the release bearing. The other two plates are below the ring.
Hope that makes sense.
I will take it off again tomorrow and get some pics.
Ron do you mean the thrust bearing? If so This can only go on one way.
The plates are aligned, although these don't require to be done individually as the centre spline is one that lines up the plate and slides onto the gearbox spline us actually one piece.
Will get done pics up.
The thing is, the box lines up, slips on to the dowls, but the tip of the gearbox spline just won't go far enough (into crank spigot bearing), and there is a gap between the bell housing and block, about a cm.
If I try to bolt it up, the engine locks, I can only assume the spline is off centre and is catching, hence lock up.
Have you had a good measure up to make sure there's nothing you need to chop down on the gearbox front cover etc? If it's locking up surely it's got to be fouling on something static? ( otherwise the gearbox first motion shaft would move with the engine)
The thing is, it's the same box which fits no problem without the clutch on, so nothing on that side should need to be trimmed down.
The issue in my opinion is the clutch. I've aligned the plates, gearbox shaft/spline slips through the plates, but then won't go any further. It's literally a cm away.
The release thrust bearing, which is obviously fitted to the fork prior (pull type) lines up and slots in.
Looking through the box, there doesn't seem to be any space for the fork to operate correctly.
It's a big clutch and just getting the box on/off is a horrid task.
He said at the top it's a hks triple pull type.
If everything lines up and it all goes together it should go in. Mine was a bugger last time. I had it ever so slightly out of line and wouldn't go in that last bit. To be honest though I knew it was slightly out and just wound a bolt in and it closed up fine.
Some clarity on the subject would be good.
Going of the earlier post, a user asked if I was sure it wasn't an R34 clutch, which usually means it should be r33 specific.
So is were the problem is?
I know the flywheel bolts are different between the r33/34.
Easy way would be to remove the fork and bearing and offer the box up and see what happens. If it engages fully then you could at least confirm that it is a bearing issue and not something physically wrong with the spigot or misalignment.
Once thats confirmed then its a case of identifying what is exactly wrong with the release bearing assembly. I appreciate that getting the box on/off aint exactly a breeze but best to eliminate the obvious rather than think too far into the problem!!!
Well I can officially confirm that an R34 clutch will not fit an R33.
What a horrid lesson to learn lol
The clutch sits far to tall, which causes for it to catch the fork mounting bracket, not allowing any further travel.
I now need another clutch, this is a step backwards and halts progress.
Did I mention my shoulders now replicate the volcanic rock look lol.
Let the pics do the talking.
Fork removed to give a better view
Clearly catching here
That 1cm gap between block/box,,'I've been fighting with.
fork mount
