Am just overhauling my gearbox (late series 2a / suffix A series 3) and setting up the mainshaft gear endfloats on the distance sleeve,
There's a lot of discussion on this on the forum and some useful videos online.
There are 3 endfloats to set:
Nobody has mentioned anywhere (that I am aware of) that you can get a massive variation in the endfloat by using different brands of snap ring. I always try and buy decent quality, but I was amazed that the thickness of different snap rings. Two OEM brands ranged for 80 thou to 93 thou (the latter being what I think it shoiuld be and the former being probably metric 2mm). In my selection of RTC1957 mainshaft snap rings (I am a connoisseur), I have a range from 0.079" to 0.096". When you are aware of this, it can be pretty useful for taking out endfloat instead of buying thrust washer (which is the traditional way).
This is really important, because if you are not conscious of it, and you set you sleeve endfloat using a sacrifical snap ring (as intructed to do), then when you come to final assemply, you could be introducing a huge amount of endfloat that takes it way out of spec. I could added an extra 17 thou of endfloat if I had randomly selected the thickest and thinnest snap rings, when the spec is 0.001" to 0.008" !!!
So am i missing something? I guess all the manauls were written in the days when you could only get Land Rover Genuine parts made by men in thick denim, so the snap rings were relatively consistent, But with so many global suppliers now, and OEM being a totally mis-used term, this is really worth highlighting. Although I used an old school micrometer (highly recommend one - my new toy) the cheapo digital ones that most of us have is perfectly good - particularly for comparing like with like.
Interested to hear any feedback!

- second gear
- third gear
- the distance sleeve itself
