I couldn`t resist to share my happiness with you guys. My 56a dogleg gearbox arrived. I`m a little worried about using it behind the a14 but i would be gentle with her...

"but i would be gentle with her..."

non-sense smash that puppy through the gears, its what datsuns were built for..

Ahhh not the 56a behind an A14! That won't last if you abuse it.

Well done Bandit. Did you manage to find a GX head?

I had 2 GX heads but i sold them, but i got one in mind complete with carbs and manifolds.

Bandit,

Was this a complete gear unit you bought or was it a new gear set?

Reason I ask is that on Peter Zekert's (he is a member here but unsure of his forum name) website he mentions the following:

"Core 5-speed close ratio 56A transmissions, with broken gears, for use in areas where aftermarket gear sets are readily available (Spain, Portugal) from $500 usd"

Do you know anything about these gear sets? Availability? Price?
Is this what your gearbox was made from?

It was a complete gearbox i bought. I`m not sure but i`m prety sure that this gearbox is almost unique in Portugal, and 5 speeds here are rare as kangaroos. I didn`t bought from Peter Zekert`s but i receive a mail from him telling me about the prices.

I wish 5 speeds were rare as kangaroos in australia too!

Lololol me too in Portugal, cause even so i think there`s more kangaroos in the zoo than 5 speeds in the country.

Bandit, I ran a 56a 5 speed behind an A14 that made 100 hp at the rear wheels, through 8 inch wide slicks with sticky rubber at the drags in the mid 80's. It survived the abuse, but what killed it was my ignorance. I didn't recognise the sound the input shaft bearing makes when it's worn, so it eventually locked up & destroyed the input shaft, the cluster gear & the 3rd gear. This bearing only really gets splash lubrication, so when the oil level dropped a little, the bearing wore out. If I'd simply put new bearings in, I'd have been fine. So from experience here are some things I'd recommend. First, a good transmission fluid, I used Castrol Syntrans 80-90w, but any good synthetic should work. Secondly, overfill the box a bit, so theres some oil getting into that bearing.Thirdly, as soon as you here noises from the box, put new bearings in it. Any bearing dealer should be able to get you new ones, just get the numbers off the old bearings. Thats all I did when I needed to rebuild a gearbox. I ran one of these boxes in my 1000 hillclimb car behind an A12, with the Syntrans, for 2 years without breaking it, though I did get new bearings fitted over the off season. Also, there's some little screws in the sandwich plate. These control the shifter feel. I'd recommend screwing them in a little, or you'll be grabbing 4th gear when you're going for 2nd, or 1st when you're going for 3rd. Enjoy your new gearbox, & remember, 1st to 2nd is now Push forward,relax, then Push Forward again, letting the spring loading take the gear stick across the gate. Works every time.

Thanks for the tips B310gx, i will follow those recomendations for sure and i will be very gentle with her!! By the way this gearbox is overdrive or non-overdrive?
