i think itd due to the power or my gearbox was on its way anyway , i have me 200 tweeked with a td5 intercooler  help needed please

Can you not mate a lt77 up to it? i dont know series so maybe they have them fitted?.

Have a look on the series 1 club forum thers a few good threads  on 200tdi conversions there.

Also try the Series2club forum, loads of info on there about the conversion and gearboxes, not just series 2's but 3's too. 200TDi do seem to eat series gearboxes if not driven sympathetically. This is probably due to the power delivery when the turbo winds up and the power kicks in, especially on a worn gearbox on an old series.

I went down the 200Di route, keeps the installation simple, less to go wrong and the power is just fine for an old 2a with standard brakes. There are plenty gone for the full install and some done alot of miles on them with no problem.

Ashcroft Transmissions offer a number of solutions for mating more modern and power-capable Land Rover gearboxes to Series vehicles but all involve plenty of green-folding stuff and work on prop-shafts or mountings. They used to do a kit for turning the permanent four-wheel drive LT77 or R380 to selective 2 or 4 wheel drive like the Series transmission. This came with free-wheeling front hubs which were useless for a Series but they refused to sell the solution without them which was annoying. I decided to try not planting the right foot so enthusiastically instead and kept Series transmission!

Regards.

yeah i am one for planting the right foot to but i think the best thing is to just take it easy  i heard the  series 2 boxes are stronger ,?

i am fitting free wheeling hubs to cut down the resistance on the road and save a tad fuel

Common generalisation people assume S2 boxes are stronger. The earlier S3 boxes are weaker than the last 2's, but the last of the S3 boxes were much better and perfectly strong enough.

DWB is right, the relentless surge torque from the turbo doesn't work well with the boxes. V8's are just as torquey and more powerful but deliver power more progressively so the boxes are ok.

Having a tweaked tdi with a big intercooler was never going to work for long with a series transmission.

thanks , i have just bought a series 3 old x reg gearbo with only 42k so is that the better box  when did the change happen ?

Don't think there was a "change" date, they just kept improving them all the time.

TBH you will blow up any standard series box with that engine setup, especially if you plant the right pedal a lot.

well i drive her smooth lost of the time but yeah i know ur should not but you got have fun its a landy

Is there a modern synthetic oil that could be used in series boxes, is it a case of the boxes wear out super fast when v8 or modified 200 tdi are fitted or do the boxes fail mechanicly?
It could be that the "normal oil" in series boxes is taken well past its limits where a modern oil would actualy make a huge difference.
just a thought.

You need to be careful with modern gear oil, definitely for a 2a box and probably with a series 3 too. The additives in modern spec oils promote leaching of copper in the old bearings leading to premature wear and hence gearbox failure. Use EP90 GL4 oils not GL5.

Go speak to Alex, who does CCVs in Boghopper: a '56 series 1 with a 200tdi in it.

Having done a couple of these conversions, it is quite possible to fit the LT77 and transfer box from a defender to a SWB series.
The big issue is clearance behind the handbrake drum, making removal of the drum "almost" impossible without modifying the main crossmember.....

The reason for fitting FWH to the front of a series is that the old UJ drive joints in a ser ft axle will give "serious" torque steer as they try to self centre under power which is why defenders, disco's etc all used CV joints (even the Stage 1 V8 Ser 3 LWB used CV's)

Eh...... no its not.

with drive to the rear (normal) there cant be any torque steer
with 4wd selected its like there are no FWH's fitted
and you wouldnt drive in 4wd with the FWH's disconected.

FWH are to stop the front axle internals n prop spinning needlessly when in rear wheel drive.
