Torque Specs

[JDT]

I know there are quite a bit of threads with people asking for torque specs but half of them have invalid links and the other half just say "get a service manual". My problem is I'm replacing a head gasket and I need the Head Torque Specs for my 420A. If someone can just point me in the right direction that would be very helpful

1. TORQUE ALL CENTER BOLTS TO 34 NM (25 FT LBS.), TORQUE THE 4 CORNER BOLTS TO 27 NM (20 FT LBS.).

2. TORQUE ALL CENTER BOLTS TO 68 NM (50 FT LBS.), TORQUE THE 4 CORNER BOLTS TO 47 NM (35 FT LBS.).

3. RE-TORQUE ALL CENTER BOLTS TO 68 NM (50 FT LBS.), TORQUE THE 4 CORNER BOLTS TO 47 NM (35 FT LBS.).

4. TIGHTEN ALL BOLTS IN THE SPECIFIED SEQUENCE AN ADDITIONAL 1/4 TURN.

Make sure you use the correct sequence. The center two bolts are 1&2, the ones to the right of them are 3&4, the pair to the left of center are 5&6, bounce to the other side, 7&8, etc, etc. Torque sequence is 1-10, in that pattern.

Hope this helps.
