Hi

Here's the story of changing the timing belt on a 1986 VW Vanagon (T3) 1.6 diesel engine. It was a bit of a fight with the hex bolts of the waterpump and crankshaft pulley. A welding machine was needed to get stuff done;

It took about 6 hours to get the job done.

The Vanagon is known as the VW Transporter in Europe.
