Need a tip. 220d belt tightening
 

I need help in tightening the ps belt on the 73 220d. All I have is a floor jack. I am having trouble putting on enough leverage on the pump while tightening the bolts. I can't raise the car high enough to do it.

Does anyone have any tips on how I can do this with just a floor jack? Is there a tool to push the pulleys apart? That would be a great tool idea.

This job makes me wish these old cars had the spring loaded pulley for serpentines.

Addendum question-

a 73 220d takes 6 quarts of oil? Thanks in advance!

My 68 220d will hold 6 quarts with a filter change.
