I nerd to know how to find tdc aldo need torque for jake brake assembly and sequence

Anything ?
Technician: Daniel Wilson,

On the flywheel housing, there is a plate with two 13mm bolts in it, you take that plate off and use a CAT pinion turning tool, looks like a starter bendix with a 1/2" ratchet hole like in a socket. The turning tool will engage the flywheel. Remove the plug on the right side of the engine behind the exhaust pipe and turbo that install a pin when the hole lines up when barring the engine with the barring tool and a ratchet. You will be on Cylinder 1 or 6 depending on which cylinder both rockers are loose. You can use a 3/8 bolt to Pin it or Cat makes a spring loaded timing pin you can buy.

I was asking for rocker arm.shaft
Technician: Daniel Wilson,
 replied 2 years ago

It is not showing up in my sis either for the SDP as I don't have the full version of sis and seems to be limited on some information. I reached out to a colleague of mine to see if they can get this information for us. I will also do some more checking in the meantime to see if I can find it as well.

Engine:

C-15 (S/N: EGH1-UP; MBN1-UP; 6NZ1-UP; 9NZ1-UP)

C-16 (S/N: W1A1-UP; 7CZ1-UP)

C-18 (S/N: CJP1-UP; MDP1-UP; MEP1-UP)

C15 (S/N: KRA1-UP; TRB1-UP; JEP1-UP; SDP1-UP; B5R1-UP; BXS1-UP; MXS1-UP; NXS1-UP; RKS1-UP)

Truck Engine News SEBD6896, 10 April 2015, "Updated Torque Requirements for Reman Rocker Arm Adjusting Screw Lock Nuts on Certain C15, C16, and C18 Truck Engines". Disregard the previous article, rocker arm part numbers have been removed.

Certain remanufactured rocker arms are shipped with larger diameter adjusting screws and lock nuts. Increased torque is required on the larger diameter lock nuts to maintain preload in the adjusting screw.

Note: Depending on core return part numbers, not all rocker arms for an affected Reman part number are built with the larger diameter adjusting screw.

The torque specifications for the original adjusting screws and lock nuts are listed in Table 1.

Table 1

Rocker Arm Reman Part Number Original Screw Part Number Screw Diameter Lock Nut Torque

20R-3317 274-4491 9.525 mm (0.375 inch)
30 ± 7 N·m (22 ± 5 lb ft)

20R-3328 274-4491
9.525 mm (0.375 inch)
30 ± 7 N·m (22 ± 5 lb ft)

The torque specifications for the new adjusting screws and lock nuts are listed in Table 2.
