What are the torqe srecs for a 2006 yzf250 head bolt?

Main bearings--31 ft lbs then turn 70 degrees.
rod bearings--38 ft lbs.
First step--Cylinder head-- short bolts-- 43 ft lbs
long bolts--46 ft lbs ,--
2nd step--turn all bolts 90 degrees.

This is the info for the 2.8d CRDI 2008-11 engine code ENS (51C)

1 Replace Head Bolts
2 Stage 1 Tighten to15 Nm
3 Stage 2 Tighten to 30 Nm
4 Stage 3 Tighten to 85deg
5 Stage 4 Tighten to 85 deg
6 Stage 5 Tighten to 85 deg

Sequence


If it is the 01-08 model 2.8 CRD engine code R2816K4 then it is this one
Stage 1 - Bolts 1 -18 = 30 Nm
Stage 2 - Bolts 1 -10 = 75 deg
Stage 3 - Bolts 11 - 18 = 50 deg
Stage 4 - Bolts 1 - 18 - 75 deg

Sequence


If it is the Grand Cherokee then they fit 3.0 CRD, 4.7, 5.7 and the 6.1 SRT-8 engines. I can supply the details if needed. I hope that helps you.

2.4L is not right, you mean the V6 2.5L ?

Long Bolts 46 Foot pounds Short bolts 43 foot pounds plus an extra 90 degree turn on all bolts. Tighten in sequence so you don't warp the head.

Get hold of your nerest bearing suppler or machin shop or a nut and bolt suppler they should have a torqe chart for all size,s of bolts
