What is torque specification of zd30 2007 main bearing conrod headbolt

The torque specifications for the main bearings and connecting rod bearings in a Ford WL/WLT 2.5L Turbo engine may vary depending on the specific model year and engine configuration. However, as a general guideline, here are the torque specifications for the main bearings and connecting rod bearings in this engine:
Main bearings:

1. Torque the main bearing cap bolts in three stages in the following sequence:Stage 1: 30 Nm (22 lb-ft)
   Stage 2: 80 Nm (59 lb-ft)
   Stage 3: 90 degrees
2. After the final torque of 90 degrees, check the bolt stretch with a torque angle gauge. The stretch should be between 0.15mm and 0.30mm.

Connecting rod bearings:

1. Torque the connecting rod cap bolts in two stages in the following sequence:Stage 1: 30 Nm (22 lb-ft)
   Stage 2: 90 degrees
2. After the final torque of 90 degrees, check the bolt stretch with a torque angle gauge. The stretch should be between 0.15mm and 0.30mm.

It is important to note that these torque specifications are general guidelines and may vary based on the specific model year and engine configuration. Always refer to the manufacturer's service manual or consult a certified mechanic for the exact torque specifications for your specific vehicle

The conrod torque specification for the MR20 engine in the Nissan X-Trail T31 is 27-31 Nm (20-23 lb-ft) for the connecting rod bolts.
It's important to follow the correct torque sequence and use a torque wrench to ensure the bolts are tightened to the correct specification. Always refer to the manufacturer's service manual or consult a qualified mechanic if you're not comfortable performing engine work yourself.

If you've got it that far apart why haven't you invested in a shop manual? Looks like you need it. Haynes or Chiltons, or possibly an online download.

Napa has them. Haynes manuals r sold at partstore
