I'm replacing a water pump seal and, unfortunately, need to first remove the
timing belt on my 93 Vigor (manual transmission). It's my first time.
I found an excellent and detail step by step instruction from the internet. It suggested that I use a crankshaft pulley tool to hold the pulley still while
losening the crankshaft bolt.
However, no one carry that tool around here. Well, can I hold it by putting the car in gear and let someone step on the brake instead of using this tool?

The bolt was tighten to 250 N m. My weight is about 650 N, much less than
the baby Vigor.

Is there anything I misunderstood about the design of
how and what this bolt is holding.

Can anyone help me understand this?, so that I can have peace b4 I get to
that pain-in-the-butt part.
