You can use a wrench over the end of the filter and use a luggage or fish scale on the wrench when you think your close (1/2 a twist after contact) use the scale and pull until you get the 17Lbs.
I will look into the 3/4 twist next time I replace my filter- if its close enough to 17Lbs that is excellent method moving forward- a whole easier too.
If you use a scale, make sure either pull 12" up the wrench of the filter to get a direct reading of foot pounds r measure how far up you are pulling to convert the number of pounds needed to pull to get 17 ft lbs. For example, 17 lbs pull at 6 inches is 8.5 ft lbs, at 24" it is 34 ft lbs.
It may be obvious but wanted to make sure no one over or under torques the filter. Best bet is the 3/4 turn approach.
Hmm, wouldn't those numbers be reversed?
Thank you all, by the way, for the many great posts.
No, the mathematics is correct...
Torque is a very INEXACT measurement of how much compression is achieved on a gasket. The amount of lubricant and type of lubricant on the seal will greatly affect the torque.You can use a wrench over the end of the filter and use a luggage or fish scale on the wrench when you think your close (1/2 a twist after contact) use the scale and pull until you get the 17Lbs.
