ande84 Posted June 26, 2009 Share Posted June 26, 2009 Hi Have just put a 200 tdi in my td. If you are not going to change the gear box you can just take the engine out by undoing all the nuts on the bell housing. Then the two engine mounts amd pipes and electrics. You just have to drill and tap out 4 holes in the disco bell housing to get the td box to fit (smaller holes are allready there). You would not have to take the seat box out as the chassie crossmeber can be unbolted so the gear box drops down through the chassie if you were to take the engine and box out as one.

jcwcooper Posted June 26, 2009 Share Posted June 26, 2009 You can take the gearbox tunnel and front panel out to make the bell housing bolts really easy to get at, makes it a doddle! Dave. Quote Link to comment Share on other sites More sharing options...
western Posted June 26, 2009 Share Posted June 26, 2009 transfer box on a 2.5TD & 200Tdi 90 or 110 is exactly the same, no need to change it or the main gearbox, which means less work/headaches for you:D Quote Link to comment Share on other sites More sharing options...

reb78 Posted June 27, 2009 Share Posted June 27, 2009 I think the LT77 from a tdi has a slightly higher ratio on 5th and a better syncro. It might be worth using the tdi gearbox - if its from a defender (diso ones are more hassle to fit). My advice before you fot the engine is check the output shafts on both gearboxes and use the one with the least wear. I didn;t check this, used the newer box, which had a lot of wear on the splines and then had to change the box after doing the engine swap! Both the TD and the tdi gearbox will work with the engine though. Quote Link to comment Share on other sites More sharing options...

reb78 Posted June 28, 2009 Share Posted June 28, 2009 hi 'reb78' gear box is off disco, but would the output shaft be the same as td shaft, cheer's defender dinky Easier to stick with what you have then, otherwise your levers will be in the wrong place - its the input shaft that is a different length IIRC. It is possible though - 2 threads on LRO about this at the moment. If your old box is in bad nick, maybe consider it... http://www.lro.com/forum/viewtopic.php?t=22397 http://www.lro.com/forum/viewtopic.php?t=35742 To be honest, the increase ratio on 5th on the disco LT77 wasn;t that noticeable on mine. The tdi boxes are considered 'stronger' though. Ratios here: http://members.shaw.ca/red90/gears.html or check out www.ashcroft.co.uk for more technical information on the boxes. Are you fitting the disco transfer box? It is a higher ratio on the Hi gears than the old defender one. If you do a lot of motorway work, might be worth it, if you do a lot of towing it might not.. It should fit on your old gearbox if you decide to keep that (might have to check the input gears are the same number of teeth first).
