Timing Belt Change Pointers
I started my 2015 HSE D4 timing belt change which is progressing nicely.
Just wanted to share a couple of points here to maybe help others facing this task.
1. The timing pins do not go into the receiving holes the same amount, the right hand one goes in less than the left hand one by about 4mm, see the images I screen grabbed from other YouTube videos.

2. To hold the crank pulley whist loosening and tightening the pulley bolt, I made a tool out of a redundant viscous fan spanner, see the image...

I watched a few but this one mainly because I was also changing the oil pump.

Be useful to see your tool close up

The only problem with this type of tool is that its not a set datum for bolts to line up, it will do one car, but the other's will not line up the holes, I found this out when I first used my prototype tool back when the cars first came out.
This is my two part tool I made for holding the crank pulley and have used for over 15 years without problems. It has variable geometry so that it can be moved to align the bolt holes.
This tool has done well over a thousand Oil pumps. As some members can testify from when I used to go down to Geoff's place for week end Cambelt changes.

Because you dont need to remove the starter motor with my tool to lock the flywheel.

By not locking the flywheel, you cannot be certain that the crank timing is 100% accurate
Yes, the crank shouldn't move once locked with the pulley locked, but the starter isn't difficult to remove, and rather safe than sorry, IMO My D3 Build Thread

I always locked the flywheel - but it's a lot easier to do with a hoist, taking the starter out on jack & stands isn't a job I'd want to do so I can see why people would chance locking the crank instead.

TBH, it's quicker to do it with a jack and axle stands

I agree with Mikey, I always lock flywheel. Then you know nothing has moved

In my case I had the flywheel locked with the 'Peg' tool, the crankshaft pulley locked with my home made tool and both camshaft timing pins still in place.
When I had finished the camshaft timing pins were still a 'slip' fit so I knew the tools had done there job successfully.Gone 2016 Landmark D4

I have had this quote over the years while using this tool, as I said its done over a thousand pump changes over the years, the most ever done on a week end was eight cars using this tool.
All customers reported after the change of the pump how smooth the car runs, this would not be the case if the timing was out.
