300tdi Manual to Auto conversion

tottot · Jun 20, 2023

If it is just oil leaks that are your problem going for a conversion to sort seems OTT to me as every thing is otherwise working normal. Do not understand "I thought it would be better to make it look and work like original 300tdi" There were NO original 300tdi Auto Landy's.
Most leaks on the LT77 and 280 transfer box are straight forward to sort, like the output shaft seals.
The one that is often left to leak in the one one the intermediate transfer shaft seal which lets oil out between gear and transfer box. Usual to remove transfer box to sort. as the shaft has to come forward to renew seal [ just an O ring]
I did mine by fitting two long bolts in two of the fixing points, removed the rest of the bolts then slid the transfer back about two inches, just enough space to push intermediate shaft forward to expose the seal O ring and replace it.

Hi just a quick advice, I was feeling knee and thigh pains while pressing the clutch. Then I replaced the front seats with BMW seats and the LOF cylinder. Seat height were raised by around 4-5 inches and surprisingly it took away the pressure from my knees and thighs. You may try some front seat raisers to see if that would help

Hi thanks for your advice, I have no experience how to remove and replace the o ring. I can try but god give me some will power

existing LT77 gearbox and transfer box has an oil leak, Craddock said labour cost will be a lot to fix. Then 300tdi Engine is sitting away from the front end, engine oil hoses and power steering hoses always has a bit of leak. So instead of spending lots of money to fix the existing stuff, I thought it would be better to make it look and work like original 300tdi.

^^ this one, if you are doing the conversion to rectify leaks you will be disappointed when your conversion leaks as well. I am not going to say all land rovers leak but all land rovers leak. The difference between them is if people bother to fix or reduce the leaks. as @tottot says most gearbox and engine leaks are fairly easy to rectify. I will also point out (although possibly not helpful at this point) that one of the first pieces of advice I give anyone looking at a defender or series is that they are eye wateringly expensive to maintain if you pay a garage rather than doing it yourself. There is always something to do and if every time there is you get a 4 figure garage labour bill the shine and joy very quickly wears off.

Why do you need to make it an auto?
There are lots out there to make the clutch a LOT lighter, or to add servo assistance to the clutch which makes it a lot easier to drive. I was going to auto my 200tdi because of arthritic knees but in the end went with a LOF power master cylinder and assisted spring which lightened the clutch considerably.
Next step for me would be servo assistance (google red booster) if my knees get worse, and if that doesn’t work then will sell!

If you have already done the lof conversion, and it has improved thing why are you still looking for an auto? I am not anti auto conversion but as mentioned on this thread it is far easier to get it wrong that right. If the reason is to try and make is feel like a modern car to drive then that will never be the case, if the issue is medical with using the clutch I would treat an auto as a last resort after trying the remote servo (red booster). There is a thread on here about fitting one but I cannot remember who posted it.

I agree with this argument, but Mrs only have an Auto driving licence. Is there any step by step manual to fix the things on my own?

Yep loads, available on tinternet for free, But Landyzone manual of brains is not bad either

. But because you have a bit of a mix you may need a couple that will cover mechanics and engine.

As for the missus only having an auto licence, you were gonna let her drive it/ she wants to drive it?

.

That was :vb-tongue-in-cheek:

mine loves getting dirty in the “mudball”

That don’t sound quite right does it :vb-groan2:

Here, you tube, google, there are genuine Land Rover workshop manualS available to download, and an old (I mean old as I. Second hand) Haynes manual. If your is a tdi get the one that only goes up to ‘95. It is far more informative than the modern one you can buy new.

Other things to consider are starting small and working up. Diving straight in with a gearbox swap is probably not a good learning job. But replacing some of the leaking seals is a nice easy start. First job I ever did was a wheel bearing and I have just complete rebuilt my 110 after a fire. Similarly with tools get a Halfords socket set and buy more tools as you need them rather than trying to get everything at once, and buy good tools otherwise poor tools make jobs harder especially when learning. By the time you have bought the tools it may not be cheaper than a garage the first time. But next time you will have them. First time I did the timing belt it cost me more in special tools than the garage quoted. But since then I have done mine 5 times and done a couple of others for friends at just the cost of parts.

Although said in jest (I am sure) this is a serious consideration. My wife will be a passenger but won’t even consider getting behind the wheel to drive my 110. And it is not a size thing she wouldn’t drive the 90 either. So just make sure you aren’t doing all this work for her to still not want to drive it.

That’s sounds like a great plan, I have a good socket set from Halfords. I have done the galvanised bulkhead on my D90 previously. I can try to find out the oils leaks to replace the seals. thanks for your precious time.

Morning sir I appreciate your concern and it’s a valid point. But we see all the time lots of female drives D90 in Dudley, Birmingham area. Anyway she will be second driver so far she has spent 12 years with me it’s going good. And she says one W from three won’t betray

I am not saying there are not lots of girls driving defenders it is whether your particular girl will

. I had the land rovers before my wife and 15 years later she still wont drive one! If she is keen to drive it then it may be easier and cheaper to give her some lessons and get a full license rather than just an automatic. If she can already drive the hard part is done, and a defender is fairly forgiving while learning clutch control. Heavy duty clutch so wont be destroyed by a learner and a fairly long travel pedal to get used to the bite point. and if you find a field/carpark she could have a go in low range where you get lots of gear changes without actually going very fast. Also back to my original point if she has not driven one before it may also change her mind about wanting to drive it at all!

Could you please count me as a volunteer on your next timing belt job?

I taught my three daughters to drive in my Ninety. Later when having got the basics in the Landy and went on to have some lessons to pass the test all three said driving a car as a piece of pi-- err cake

We took delivery of our 90 when I was working away, M sent me pics after she tried it out

Guess it was ok

.

For the OP actually getting the missus to do the full license would not be a bad idea anyway, Then if it really came to it at least the conversion could be planned and saved for.

Hi do you have any idea if gearbox or transfer box seals would need replacing then do I have to take them out?

It depends which seals need replacing. The transfer box output seals can be done without dropping the box. The access panel gaskets can be replaced wothout dropping the box’s. But transfer input, and gearbox input and output both require the box to be removed.
