You are watching: Rocker arm torque specs for chevy 350


Hi I need to recognize the torque specs for the rocker eight on a small block Chevy 350. Is there a specific pattern? I"ve checked out specs ~ above the rocker studs yet nothing on the rocker arm nuts. I"ve also heard something about tightening them till there is no more play in the push rod, and then 3/4 turn. In what direction ns dont know.
Good ar to examine out:http://www.boxwrench.net/specs/chevy_sb.htm__________________Best car Insurance | Auto security Today | free Trade-In Quote
Rocker arm adjustmentYou can adjust hydraulic lifters v the motor running or no running. Youwill require some type of oil control machine to execute it with the motor running. Themost accurate way with the motor turn off is one cylinder in ~ a time with the cylinder on the compression stroke. There is also a means to do part of the valves then revolve the engine 360 degrees and also do the rest. The methodescapes me. (Can anyone refresh me?) The adjustment is the very same in all cases. Find zero lash and also tighten 1/2 to one full turn more.http://www.picturetrail.com/yelrah_dave

small block chevy
Hey dude, it has actually been years since i functioned in chevy dealership but i prefered engine occupational when i was there. I did it so lot i acquired lazy and would run the seed down about a half inch in each stud. Regaurdless of i beg your pardon pistion to be up, understanding that about half thread is what itis walk to finish up through anyway. Indigenous that point the valves to be tight enough to allow the engine to run however i had actually chatter on all the rockers. Then i would turn then slowly crank down till the engine started missing, At that time earlier off simply a tiny and leaving it there. Move on come the next. (this only works if you have actually hydrolic lifters that have been pumped up) this is the fasted method i found.
Are girlfriend a technological writer for Haynes or Chiltern ? ain:
For HUH?, collection the number one cylinder in ~ TDC firing place and set the exhaust valves top top cylinders,1, 3, 4, 8 and the join on,1, 2, 5, 7.Rotate the crank 360º and set the exhaust valves on 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 because that Chevy.Edit: Preload, Chiltern claims 1 1/2 turns in and also Haynes reckons 1.
Thanks malc
malc,Thanks for your reply on setup valve lash. Your technique is rapid andplenty accurate sufficient for hydraulic lifters. As soon as you happen fifty year of ageyou lose countless things. Storage is normally the second, ns can"t really remember the first!Dave
Obvioiusly most people are concentrating top top lash adjustment.The rocker eight nut still calls for TORQUE.If the self-locking nut has insufficient speak the adjustment will certainly not remain constant.Look for around 10-15 lb/ft speak on the nut-to-thread drag.
ns think he"s talkin" about the nuts. If the speak is less, change the nut together the self locking attribute has been compromised.
