Welll....
unfortunately they are not compatible.... two different PN:
the 205 uses two different pn for the two bearings:
3723020200 and 3723020210 for the 205 1994/10 and later
3723020150 and 3723020160 for the 205 1994/02 to 1994/10
the 165 uses same pn for the two bearings:
3723020120 for the 165 1988/04 to 1989/08
3723020110 for the 165 1987/10 to 1988/04
double unfortunately, the 165 one (3723020120) has been discontinued long time ago......
However, I remember looking at this problem quite few years back (just after I found out the 165 one is discontinued...) and came to the conclusion that with a bit of engineering skills the 3723020200 (205 one which can still be found) can be made to fit in the 165 application. Fortunately for me I didn't need to go that route as I could locate a pair of the correct 165 ones and got them ...that was quite few years back....
