Just a couple of clarifications needed,
should I use the datsun or the toyota thrust bearing?
I have an a14 flywheel on an a12, should I be using the long or the short bearing carrier?
Are there any known clutch issues associated with this conversion?

My problem is this: When in nuetral with the engine running. gears cannot be selected, I have to turn off the engine and select a gear. Once in a gear, it slips real bad. But the gear selectin issue seems to only be an issue when the gearbox warms up?
Also only when its been going for a while, it will drive foreward with the clutch all the way in.
I've tried adjusting the clutch cable but cannot find a happy medium.

If anyone can read that an know what the problem is, that'd be sweet, but any advice would be helpful.

Next week I'm going to change the clutch, but i think it may be more than just a clutch issue

sorry about the long post,

I once had a problem with one and I rang Dellow,I spoke to the guy who designed the conversion and he talked me through the problem ,very helpful.

I used the datsun carrier and bearing
Is it possible the input shaft is too long and fouling in the back of the crank ?
I found this when I fitted a box once and didn't put in the sandwich plate.
Make sure you fit the supplied brass spigot bush into the flywheel so the input shaft has something to centralise it
Otherwise the box will jump out of gears and eventually fail. Usually worn brg or broken input shaft.

cheers guys,

nah its not fouling on the crank, I'm pretty sure of that. The brass bush, however, had been put in on an angle and has worn an oval-shaped hole, I put it back in rather than ordering a new one (will order a new one this time).
I think I'll get another gearbox (this one noisy etc) and change gearbox and clutch over easter break. If I find anything I cant figure out I'll be right back here asking ;)

t-50 as in a toyota t-50?? a ae86 box? that is awsome i have never heard of anyone doing that sort of thing. when you get it working properly let us know. did you now you can buy TRD cross gear sets that are next to imposible to brake... they also cost around 15 grand, i think but the posabilities.....

AE86 T50 I think has a bigger input shaft?

but yeah toyota T50, quite a few member have them working well, I'm getting there :)

oh sorry abuot my ignorence. i have seem people mention things about 5 speeds before but i never knew what they got them from. what did you get that particuar t50 from if you don't mind me asking? i have drove my mates ae86 levin and that has a nice shift.

you don't want to buy a short shifter do you? the same mate is going to remove his because his mates (me and others) complane about the shortness. he said once he got used to it he cut down his shift times heaps. i can give you his number if you are intrested.

Is there any particular reason why you are using the heavy A14 flywheel on an A12 engine? This would reduce your acceleration times.

Would it be possible to use an A12 flywheel on an A15 with the same gearbox conversion. The motor has a 31-71? cam, twin 40mm DCOE webbers, has a 40 thou over bore and has extracters with 2 1/4 inch exhaust.

If not, should i just get the A15 flywheel machined?

Dodgeman, I only used the a14 flywheel because the ring gear looked better. I had ~5kg taken off it anyway...
