Some torque specs on head bolts require an additional angle torque after the initial foot pounds (or Nm) has been completed. Example, torque the head bolt down to 70 ft lbs then an additional 90 degrees. The torque gauge measures that 90 degrees for you so you can be accurate.
A torque angle gauge is used mainly on torque to yield fasteners. T.Y. fasteners are 1 time use only. They usually have an initial torque setting and second torque setting and then an angle,(for example 30ft-lbs., 60 ft-lbs. then 90degrees). After the second torqueing you sent the angle gauge to 0 and turn to 90 or what every degree is required.
After torqueing I would use a regular ratchet with the angle gauge so you don't damage or through off the torque wrench calibration.
To torque to 70 degrees, tighten the fastener to the specified torque value, then use a torque-angle gauge or a torque wrench with angle indication to measure and turn an additional 70 degrees. This method ensures accurate and precise torque control on critical fasteners.
For this job you need an angle gauge to attach to your socket bar,they are available for about
18 lb/ft +70, +70, +30 Degrees using angle gauge,
Torque is a measure of the force that can cause an object to rotate around an axis. The angle through which the object rotates is proportional to the torque applied. As torque increases, the rotational angle also increases, assuming all other factors remain constant.
usually the veinipuncture is using a 21 or 22 gauge needle at about a 30 degree or less angle.
New bolts required,they are "use once"stretch bolt.Also,an angle gauge is required,or you can make one from card. Torque to 35Nm + 45 degrees + 15 degrees.
For this one you'll need a torque wrench and an angle gauge. Hope you are familiar with these. The values are 25Nm+600+600+600. These are from General Motors workshop manuals so I trust them 101%. G.Ikenye
You need to refer to the manual. But to partially answer the question, you will need to torque the head bolts in three stages. Two of those stages require a torque wrench and the third requires a torque angle measuring gauge. I ve dont this twice and you REALLY need a manual for this OR check some Volvo forums.
The stator inside the torque converter directs the fluid at an angle to trans. part of the torque converter amplifying the force on the vanes.
The purpose of measuring taper angle is to obtain taper angle
