Hi guys,

When replacing the waterpump on the M110 280 (W123) - how do you get to the fifth bolt!? Four are fine but the fifth is obstructed by the harmonic balancer wheel.

On the older ones like my W108 there is an access hole for the ratchet but there is no hole and it seems to be much more difficult on this one??

does the harmonic balancer wheel and all have to come off???

help please!
