@Stig,
thank for the info about topcase colors, here you see a wide variety of different mix at LIKEs.
And yes, there are a lot of LIKE 200i around here in Italy, particularely in southerly regions, since most used 200th come from ROMA or even more south.
Now to pics from oil seal and bearing surgery.
Sorry not to have more in detail, but during tinkerin'
gear oil and pics, ...
Anyway:
bearings are standard int. numbered and oil seals are in millimeter, inner diam./outer diam./hight
A) crank shaft seal 19.8-30-6 (behind this shim)
could not get a 19.8, so I took a 20mm inner diam.
B) oil seal between gear and clutch 20-32-6 mm
C) motorside gear with this 20-32-6 and 6204 bearing
D) gearbell with 27-42-7 oilseal and 6004 LU bearing
E) gearbell with new 6004 LU bearing in it
F) airfilter "brandnew"
G) separating gearbell
Taking out an oilseal is simply done by taking a spiky tool and a hammer, drive with some common sense this tool trough the seal without harming the outer or inner surface, pry it out.
Renewing ball bearings works like always, when cast aluminium and steel bonds:
Heat up the alu part by heat gun, set a puller and voilĂ ..
Setting the bearing , reverse, heat up the alu, put the bearing in the frezzer for awhile and drop it into those sizzling hot seat.
And btw, (pls see pic, this was the LXs airfilter) never ever believe if somebody tells you an vehicle was regularely maintained by dealership, has a new MOT and all filters and oils were changed recently.
