What is the torque of a head bolt?
Tighten bolt (27) through bolt (33) in a numerical sequence to a torque of 28 ± 7 N·m (20 ± 5 lb ft). Install the head bolt spacers on the three head bolt studs. Tighten the three head bolt studs to a torque of 100 ± 20 N·m (75 ± 15 lb ft).

How to calculate torque on a 2K engine?
Apply clean engine oil on the surface of the lower half of connecting rod bearing (5) . Install connecting rod cap (2) on the corresponding connecting rod. Ensure that the numbers are on the same side. Install connecting rod cap bolts (1). Tighten the bolts to a torque of 130 ± 7 N·m (95 ± 5 lb ft). Place an index mark on each bolt head.
What is the torque of a compression brake?
Tighten the bolt to a torque of 35 ± 3 N·m (26 ± 2 lb ft). Position compression brake housing (4) on the studs. Install nuts (1) and tighten to a torque of 80 ± 15 N·m (60 ± 11 lb ft). Install bolt (3) and tighten to a torque of 55 ± 10 N·m (41 ± 7 lb ft).
The first pass would be a torque of 36 foot pounds. This is the elastic deformation point. The second pass would be a 90 degree angle or a quarter turn. At this point the bolt is going into plastic deformation. The third pass would be another 90 degree angle.
What happens when torque is applied to a fastener?
On any fastener, when a torque is applied to a bolt to create a given clamp load, friction is created. Let’s use a head bolt as our example. The bolt manufacturer tests its bolts to create the given clamp load that will allow the head gasket to seal properly.
Are there torque to yield bolts on Subaru?
These head bolts are torque to yield bolts, but with my experience I have Never replaced Subaru head bolts during head gasket replacement. The same goes with Toyota engines unless I get one of those Toyota Camry’s that pull the threads out of the block.
How to measure torque when ratcheting a bolt?
This is commonly used to ensure bolts are torqued during assembly. If you don’t have access to a torque angle gauge (as rpmerf recommends) or space is tight, here is one possible way estimate the angle with a ratchet: Without any socket on the ratchet, rotate the square drive head 180° by hand while counting the number of clicks felt.
