Head Bolt Tightening Sequence Pdf Cylinder head bolt tightening sequence free download as pdf file (.pdf), text file (.txt) or read online for free. the document provides instructions for tightening cylinder head bolts on different engine models. When tightening (torquing) the cylinder head bolts, the bolt force generates the so called surface pressure, which is essential for achieving a perfect seal. hereby, and in combination with the applied torquing method, the bolts have a strong effect on surface pressure quality.
Cylinder Head Bolt Tightening Sequence Pdf To achieve a new flange connection that is leak free, there are a number of different things to consider, one such being the bolt tightening procedure during installation. Refer to the 16v cylinder head and head gasket removal and installation procedure for the correct sequence. Advantage of stretch bolt: as opposed to a rolled shank bolt, it can be tightened beyond its elastic limit (yield point) into the plastic region – a guarantee for high and uniform bolt clamping forces. Tighten cylinder head bolt to 7.5 kgfm (hold for 3 seconds) in sequence as marked. turn the cylinder head bolt to 80° using the angle indexing tool in the same sequence as marked. hold for 3 seconds. (part number: 2576 5890 0204) or standard tool available in market.

After 1 hour, check the torque; it should remain at 220 lb·ft in the same sequence. before starting the engine, repeat the same procedure twice and verify that the torque remains consistent after the engine has settled. For proper ansi flange bolt tightening, follow a sequential “star” or criss cross pattern, tightening bolts in stages to ensure even gasket compression and a secure, leak free connection. Fel pro head bolt sets are available for many domestic and imported engines. the torque tables™ indicate which engines have bolt sets offered in the fel pro product line. the torque to yield procedure stretches the bolts into their elastic range.
