Thread: gearbox identification help

ok ive done some more net research and it looks like my series 3 has a 2A suffix A or B gearbox due to the split sirclip and lay shaft layout..

but come on guys, I need some experienced input to assure me that Im about buy the correct 1st gear and main shaft 1st gear for my old girl, the rear layshaft bearing seems to fit all the gearboxes..

i also need a complete gasket kit so the correct box version is needed


cheers

Hi Madmax,

Can't help with the actual suffix of the gearbox but if you had a 2a gearbox then you would have no synchro on 1st and 2nd gears. A very noticeable difference between the two gearboxes when driving them and should be easy to pick also since you have the box apart.

G'day Madmax,

I think the ID number you need is here



Then you might find this link helpful

see now this makes me more confused, I have synchro's on first and second gear...

this box has the dual cogged reverse idler gear, and the idler shaft can be dismantled completely (all gears come off shaft like series 2 boxes)

'76swb:

I have checked there and there is no number stamped there.. i can just find the 2 shown in the above pics

early series 3 perhaps, but as far as i can tell the series 3 all had the single reverse idler gear, not the dual i have and the idler shaft was one piece,

not sure now, ive got next week off, so was hoping to get the old girl back on the road for the first time in 5 yrs

finaly found the vin number on the chassis, left hand rear (passenger side) on the rear spring support bracket.. 34709667C

according to Land Rover Series Resources

347:
Model: Land Rover, Series IIA
Body type: Basic
Wheel base: 109in
Engine: 6-cylinder
Model years: 1966-1971
Destination: Completely knocked down (CKD), right-hand drive (RHD)

09667:
Serial number

C:
Design: Two significant design modifications
Suffix used from April 1966 till April 1967

so its a 66-67 series 2a chassis with a series 3 cab on it, and it registered as a 1971 series 3 with holden modofication, this explains the the series 2a gearbox....

btw whats a 'basic' body type?, atm it is a cab chassis

looks like a vehicle built in UK dis-assembled then sent here and re-assembled, I dont have any vin plates or manufactuer plates anywhere on the cab or chassis to id the re-assembler.

that was originally, now its like a bit of a patch up vehicle, virtually every panel was different colors, on a different series chassis with a 186 motor, at least the chassis and gearbox look matching, but then there is no suffix on the box just the number above...

but this is what makes these cars special, you never really know what your getting

To add to your confusion, this image shows your gearbox number, which is a 1958 series 1 number. The top cover is easy to change though.

Why do you have a SIII body? By 1967 the wipers had moved to the single wiper assembly in the firewall, and in 1968 the lights moved to the guards. Beyond that the only body changes until SIII were hinges, grille panel, firewall/dash and doors - but most of these happened gradually.
I have seen SIIIs that have had the firewall replaced with a IIA type and vice versa.

The thing to do now is check:
1. Remove the t-case intermediate shaft to see if you have the early or late type
2. Check the gearbox ratios to see if you have SI/II or IIA ratios.

here she is, on stands with the box out getting the above bearing replaced, a bit hard to see, but the head lights are on the front guards, not next to the grill



what do you recon, 2,2a or 3?

as for the syncro, its got a syncro hub, from what the net displays its a 2-2a, ill get a pic up of the main shaft tomorrow... it also has the 15 tooth first gear, and the lay shaft can be stripped and has the 2 piece circlip

are the gear ratios marked on the gears them selves?

as you can see Ive got a little way to go before im happy with it, a new paint job, mechanical repairs and checks, get both front and rear tanks linked up together but to get to box repaired and get it moving is priority

and fit my new purchase, front PTO

Well the grille is 3 and the door hinges are 3. Is the top of the dash padded and the speedo behind the steering wheel (series 3) or is the dash all metal with the speedo in the middle of the car (Series 2)?
