Hello,
Since in this area of the engine I really don't know proper English names for things, I will use a picture (see below). After some consultance and looking into the matter, I think the o-ring in the diff leaks (as you can see on the picutre, it's a bit messy - and this is after cleaning up). The o-ring I talk about is marked with A and a red line (although probably it actuall sits a bit deeper). Now two questions:
1. What size is this o-ring? Does this have to be a special one from fiat, or a standard one (properly sized) will do?
2. Can I replace it without taking the gearbox out? My plan of attack would be the following (but I am not sure I interpreted everything correctly in the service manual).
(a) I drain the gearbox
(b) I take the drive shaft out (yes, I know, it only sounds simple) and take the exhaust out of the way.
(c) I take element B (what's this damn thing called) out. According to my understanding it should just slide out, or am I totally wrong?
(d) I replace the o-ring (that I guess will be tricky and brige will be needed for good access).
(e) I put everything back together, not forgetting to put new gearbox oil in
Or am I absolutely off... Any help on this would be greatly appreciated.
