I am a new guy to the Volkswagen Diesels, I read the write up and it seems very direct, I do not want to get the tool kit and find I need the other crank locking tool is the diesel geek kit for the BRM what I need for $120. I will buy the other one also I hate multiple use tools they never seem to work correctly on either. Just my opinion.
Great site and great articles.

You Don't really need the complete tool kit. Just the crank lock and you can lock the cam with a letter "A" sized drill.

You don't really need the tensioner lock either, even though some tensioners come with it.

What I do is to slide the tensioner away from the head and then put the belt on the crank, water pump and tensioner and then put the sprocket inside the belt.

Then put the sprocket in place and slide the tensioner to within about 1/4 inch away from the head. If the bolt holes are about in the middle of the slot, put 1 bolt in to hold the sprocket loosely in place, line up the tab and push the tensioner against the head and put the tensioner nut on finger tight.

Install the other 2 sprocket bolt and make sure all 3 are finger tight and then loosened about 1/8 of a turn. tension the belt and lock down the tensioner and tighten the 3 bolts snug but not torqued yet.

What I do next will set your timing very accurately.
  • Remove the cam and crank lock
  • Turn the engine 2 revolutions till the crank lock is a slip fit.
  • Loosen the 3 bolts on the cam
  • Turn the cam center bolt (slightly) for a slip fit on the cam lock
  • Re-adjust the belt tension if required. (it will be off)
  • Snug the 3 cam bolts
  • Make sure both locks still have a slip fit and remove them
  • Turn the engine 2 more revolutions till the crank tool is a slip fit.
  • If the cam tool is still a slip fit, remove the lock tools and torque the 3 cam bolts and the tensioner
What you just did was compensated for belt stretch. I did my BRM this way twice because the new cam seal leaked the first time and I got a Torsion (cam to crank timing) value of -1 the first time and zero the second time. Very accurate indeed........

Just to be clear for anyone else reading this, you are right, you only need the crank lock and any pin equivalent in diameter to the VW pin. The dimensions are listed in the writeup.

The technique is what is important and is listed in the writeup.

The write up will get you pretty close were my technique will get you spot on every time. I would consider my technique to be a refinement to an already excellent write up.

I have the purchased a once used timing belt tool kit off eBay. This kit included the T10050 crank lock; however, in my research it seams that this is 1 of 2 versions that i may need.

Which one will i need? I would like to have all tools and parts prior to tearing into this job.
ALSO
How do you use those long blue sprocket tensioning tool.

thank-you all inadvance for you time

You need T10100, 50 is for the older engines, they are different. the 50 sprocket is for a round crank sprocket, 100 is for an oval crank sprocket, and the arrows are in different locations.

Read the FAQ, it shows the blue sprocket tool in use. Technically you don't need it, you could sub it since its purpose is to take the slack out of the water pump side of the belt. I show its use because that's what the manual says to do.

putting sprocket back on

does anyone know how will I know for sure that I put the sprocket on correctly? I know it has to be precise otherwise it can do a damage to the engine. Are there any marks on the sprocket, in bentley manual says that the 3 bolts need to be centered how will I know that they're centered enough?
Thanks,
Rado

Look at the pictures. There are no marks on the sprocket, eyeball the ovaled bolt holes. The bolts should be in the middle. When you tension the belt, it should move so that tension is spread evenly, then you tighten the bolts.

I agree, great write up! Was reading some of the other posts, I completely agree with not having to purchase the locking pins, I use drill bits as well. I recomend wraping tape around the point of the bit to use as a handle and to protect yourslef from the sharp point. This way, you can also use the base of the bit to better fit into the hole.

98 Jetta Timing belt change

I just found you guys a few weeks ago. Wanted to let you know how much better info you have for changing timing belt than Bentley's. (Not to knock them. They have been helpful, but the finer points you have are so helpful, such as what bolts go where - even the lengths, details on the tensioner pulley. I couldn't figure out where it hooked. You showed it.) Thanks much!!
