aloha
my mechanic removed seized smog pump.
his solution is to put a dummy pulley in it's place.
other threads never suggest a pulley substitution.
his original dilemma was finding the correct belt size to use without the smog pump in place.
i do not know if this is a double over head cam or earlier motor.
any help
please?

The belt from a pre-1990 300E or 260E will fit. They did not have the smog pump. It is exactly the right amount shorter.

thank you for the reply.

he said he tried earlier belt but is too snug /
alternator on right ?

I can double check my belt tomorrow... my 300sel is handy and the air pump fell off one day.

thanks for the help.
guess the redheads are mine.

The belt tension is adjusted with the tensioner once the belt is in place....perhaps he is just not making the adjustment properly?
