I was changing the oil to the lower unit a Volvo Penta DP, but when I was ready to tighten down the dip stick on the top it just kept on spinning with out tightening then I unscrew it and the tread to the lower unit broke off, what are my options any help is appreciated, thanks.

Qualified mechanic or better a machine shop

extract the broken piece and install a tread repair insert.
Ask if they use Helicoils or Timecerts..................the Timecert is a way better way to go for thread reapirs.

Wish you best of luck that sucks

Which model of drive? I ask because a some of the volvo top caps are helicoiled from the factory. This is a common problem and easy to fix. A few of the coils are order-able from your local dealer.

well the best way to fill these volvo units iz

remove the shift cover

you will see a flat head screw on the unit on the right

remove it

now fill the fluid, when it comes out this hole, that is the bottom of the dip stick, one more pump fills it perfect

timsert is what ya need

i found out this procedure when i played with these untis for a few years

even master techs have no clue about it!!!
