• Timing AAZ with adjustable IP sprocket out of car---no flywheel by wpinnix on 07 Jul, 2010 01:07
• I've got a 1997 AAZ with the adjustable Injection Pump sprocket. I'm replacing timing belt, water pump, tensioners, etc. I have 2 issues at the moment.
  
  1) I have no flywheel on the engine at the moment (I purchased it without); AND since no transmission is attached....How do I find TDC for the crank?
  
  2) when the engine is at TDC (judging by cam timing and cam lobes for #1 pointing up) the timing hole for the Injection Pump is off by about 1/4". Do I simply loosen the sprocket and turn the 19mm IP nut until the holes line up?
  
  Thanks,
  Bill

• You require a flywheel to time this engine with or without the transmission.  The cheapest is use the transmission, no special tools required.

• The flywheel and transmission are in the car with another engine attached. The engine I need to time is on the engine stand. I need to remove the rear timing belt cover to cut out a notch for my engine mount......thus necessitating the removal of the timing belt and IP sprocket cam sprocket and intermediate shaft pulley.
  
  there has got to be a way of knowing that the crank is at TDC without having it mated to a transmission.....just need some input on how to do it.

• Vw makes a specific tool to find TDC with no tranny but it is rare and spendy... Otherwise you can jury-rig a dial indicator down injector 1 or 4.

• Or post a WTB for the top chunk of a transmission with the timing hole. That's what I did to my old blown up 5 speed.
