Removal and Re-installation sequence for bolt removal and tightening.

If yours is an Xu series engine, you need to use a torque wrench and an angle dial wrench. Tightening is in 3 stages.

• Stage 1: Tighten up to 60Nm (44 lb/ft) then fully loosen
• Stage 2: Tighten up to 20Nm (15lb/ft) change to angle dial wrench
• Stage 3: Angle tighten to 300 deg.

To avoid confusion, do stage 3 in 3 steps, tighten 100 deg each round and repeating the cycle until 3 rounds.

take all slack out of cable . take derby cover off loosin lock nut in center if pack tighten addj screw turn in till seats back out 1/2 to 1 turn tighten lock nut . take slack out of cable . hatleytalking.con ...good luck

I think you will like this.

1998 Hyundai Lantra "G4GM" engine 1795cc.there are two heads or blocks, one is called the M10, other is the M12, figure out which one you have cause the torque is different for stage one by 5nm........... Dont get confused theres 2 different engines so 2 different torques for stage1---------
heres the full details: Stage 1 - m10 = 30nm / m12 = 35nm-------------------------- -------- Stage 2 - tighten by 60-65 degrees ------------ stage 3 - tighten by 60-65 degrees. no sequence is given in the data book for tightening so go off what you thinks right, it doesn't matter on this engine.

Tightening torque
With used parts (head bolt, cylinder head cylinder block) : 20Nm (200 kg.cm, 14 lb.ft) + 90° + 90° With new parts (even if only one thing is replaced) : 64Nm (640 kg.cm, 46 lb.ft) + release+20Nm (200 kg.cm, 14 lb.ft) + 90° + 90°

This procedure is for the SOHC only.

E: INSTALLATION
1. CYLINDER HEAD

1. Install cylinder head and gaskets on cylinder block. CAUTION: Use new cylinder head gaskets.
2. Tighten cylinder head bolts.

1. Apply a coat of engine oil to washers and bolt threads.
2. Tighten all bolts to 29 Nm (3.0 kg-m, 22 ft. lbs.) in alphabetical sequence. Then tighten all bolts to 69 Nm (7.0 kg-m, 51 ft. lbs.) in alphabetical sequence.
3. Back off all bolts by 180° first; back them off by 180° again.
4. Tighten bolts (a) and (b) to 34 Nm (3.5 kg-m, 25 ft. lbs.) .
5. Tighten bolts (c), (d), (e) and (f) to 15 Nm (1.5 kg-m, 11 ft. lbs.) .
6. Tighten all bolts by 80 to 90° in alphabetical sequence. CAUTION: Do not tighten bolts more than 90°.

1. Further tighten all bolts by 80 to 90° in alphabetical sequence shown in figure provided. CAUTION: Ensure that the total "re-tightening angle" [in the former two steps], do not exceed 180°.
