How to check the gear train timing without taking the gear train cover? Detroit ser 60 14L DDEC V.

Is it possible to check the timing between the crankshaft and camshaft without taking off the gear train cover with this tool ? http://www.apexinds.com/mm5/merchant.mvc?Screen=PROD&Product_code=M30138

 

The truck starts right up and runs well on flat, but doesn't have the full power on hills. Before removing the head this truck was climbing better on grades. After putting reman injectors, new inj. harness, new check valve on the back of the head, new fuel pump. Checked the fuel pressure.

The last two things I suspect are: Timing is off maybe 1 tooth or the injectors and valves are not done correctly.

Some mechanics are not making difference between 14 L Detroits. There are 14L with N2 injectors DDEC IV and 14L with N3 injectors DDEC V also 12.7 DDEC V with the same cam and injectors.

Here is the file with the spec. For this engine should be:

14 L , DDEC V , model HV_E, camshaft 23532935, year 2004, between 6.655 mm (0.262 in.) and 7.214 mm (0.284 in.)

 

I was wondering, why Detroit Diesel (W.W.Williams) charges 8 hours to check the timing. Why? With this tool will be a lot less. I don't want to spend $668 for a tool that will be used once.

I am getting 40 psi turbo bust, but the truck still will not run like before.

 

Ok, then. I am thinking to do the overhead again. This time I will measure the injector lobe at TDC. If it is right in the spec, the only thing left are the injectors. I put rebuilt injectors, but not from Detroit, some shop in California. If they rebuilt them with wrong parts... maybe this is the problem. The part number is correct.

0 414 703 002 - this is for DDEC V - 12.7L motor 7.7 flow
0 414 703 003 - these are on my truck - 8.8 flow
0 414 703 005 - industrial - more flow
0 414 703 007 - industrial - highest flow

 

Yes I know the procedure. Some people even back off not 3/4 but full turn and saying, the engine runs smoother. I have seen engines with bull gear marks aligned and the injector lobe not in spec.
