You are watching: Chevy 350 rocker arm torque specs


Hi I need to recognize the talk specs for the rocker eight on a little block Chevy 350. Is there a particular pattern? I"ve watched specs ~ above the rocker studs yet nothing top top the rocker eight nuts. I"ve also heard something around tightening them until there is no more play in the press rod, and also then 3/4 turn. In what direction ns dont know.
Good ar to inspect out:http://www.boxwrench.net/specs/chevy_sb.htm__________________Best vehicle Insurance | Auto protection Today | cost-free Trade-In Quote
Rocker arm adjustmentYou can change hydraulic lifters with the motor running or not running. Youwill need some type of oil control maker to do it with the engine running. Themost accurate way with the motor turn off is one cylinder at a time through the cylinder on the compression stroke. Over there is also a method to do part of the valves then turn the engine 360 degrees and do the rest. The methodescapes me. (Can anyone refresh me?) The convey is the exact same in every cases. Find zero lash and also tighten 1/2 to one full turn more.http://www.picturetrail.com/yelrah_dave

If you do a search in the expertise base or using the search role on adjusting rocker arms, you"ll find all you require to know on it. If you still have actually questions, come back and ask .Dylan.

Hey dude, it has been years because i operated in chevy dealership however i prefered engine job-related when ns was there. Ns did it so lot i obtained lazy and would run the seed down about a fifty percent inch in every stud. Regaurdless of i beg your pardon pistion to be up, understanding that about half thread is what itis walk to finish up with anyway. From that allude the valves to be tight enough to permit the engine come run yet i had chatter on all the rockers. Then ns would rotate then gradually crank down until the engine began missing, At the time back off just a little and leaving it there. Move on to the next. (this just works if you have actually hydrolic lifters that have actually been pumped up) this is the fasted way i found.
Are you a technological writer because that Haynes or Chiltern ? ain:
For HUH?, set the number one cylinder at TDC firing place and set the exhaust valves on cylinders,1, 3, 4, 8 and also the intakes on,1, 2, 5, 7.Rotate the crank 360º and collection the exhaust valves ~ above cylinders, 2, 5, 6, 7 and the intakes on, 3, 4, 6, 8.According to Chiltern, Haynes left the end number 1 cylinder in theirs.BTW for Chevy.Edit: Preload, Chiltern says 1 1/2 transforms in and also Haynes reckons 1.
Thanks malc
malc,Thanks for her reply on setting valve lash. Your technique is quick andplenty accurate sufficient for hydraulic lifters. When you pass fifty year of ageyou lose countless things. Memory is usually the second, ns can"t yes, really remember the first!Dave
Obvioiusly most world are concentrating ~ above lash adjustment.The rocker eight nut still needs TORQUE.If the self-locking nut has insufficient torque the adjustment will not continue to be constant.Look for about 10-15 lb/ft torque on the nut-to-thread drag.

ns think he"s talkin" about the nuts. If the torque is less, replace the nut together the self locking feature has to be compromised.
