Default Timing belt replacement 300 TDI

I recently broke the bolt holding one of the tensioners for the Cam belt. I have a service manual which generally address the replacement of this belt as a routine service item. not as oops I broke my belt. A few questions about order of operations

Here is where I sit

1. Belt is gone and old sheered bolt is removed

2. Pump pulley is aligned and locked in place with pin

3 middle pulley is aligned with hash mark.

4 Cam is still sitting in random position awaiting the tool to lock this into the TDC position.

5 Rocker removed and push rods inspected. 1 slightly bent. .. replaced all of them

6 Polished and oiled Rocker assembly


Do I need to rotate the cam into TDC before re installing the rocker assembly and adjusting valves?

Any pointers or comments on what has been done so far?

Thanks for your help and any ridicule you may have for me LOL

There are some great videos on YouTube you should consider watching too. For me watching makes a big difference.

I would have posted this a few minutes sooner, but I got distracted by cats and cucumbers.

Yes, turn the cam and injection pump to the mark for the timing belt and the crank to TDC, then install belt. You can put the rocker shaft back on last.

Make sure you carefully look at the rockers for cracks.
