Asbestos Free, Fit Dry
NOTE
The cylinder head tightening procedure for the AQ model engine remains the same as previous 1000
Series engines. However, the tightening procedure for Model AS (103mm Naturally Aspirated Engine)
varies, the following procedure must be followed.
1. Prior to re-use, all bolts must be checked for a reduction in the diameter of the bolt, usually noticeable in
the unengaged portion of the thread.
2. All Bolts should have light lubrication on the threads and underside of the bolt head.
3. All M10 bolts should be tightened to 45Nm and the 4.5-inch UNF bolts to 110Nm following the sequence in
section 12 of the Perkins Workshop Manual.
Following the same sequence, all fixings should be tightened a further angle depending on their size, see
below.
The short and medium M10 bolts should be tightened by 120 degrees.
The long M10 bolts should tighten by 150 degrees.
The 0.50-inch UNF bolts should be tightened by 180 degrees.
Exhaust Manifold
If a new exhaust manifold is fitted to the cylinder head it must be aligned using two nylon bushes. The bushed
must be fitted to the bolts indicated below.
