TC Adjustable 3/8 OD tube, 0.134 wall thickness, set of 4 pushrods

  • TC Quick Install Adjustable pushrods, 3/8 OD tube, 0.134 wall thickness, set of 4 pushrods. Individual length Exhaust and Intake pushrods, Install WITHOUT the removal of rocker covers, requires quick install tubes - see Feuling #4095 for tubes only or Feuling #4097 for pushrod + tube kit

    This is the strongest Quick install pushrod on the market! The strength and rigidity of this quick install pushrod is second only to heavy duty one piece pushrods. Our tube material starts out as 7/16 rod OD, it then gets turned down to 3/8 OD leaving heavy duty 7/16 - 20 threads for the base and jam nut. The jam nut slides up the pushrod, the base then loosens up into the pushrod to allow quick install access.

    *This part # supersedes Feuling #4090


    CORRECT PUSHROD/LIFTER ADJUSTMENT REQUIRES STARTING WITH FULLY PUMPED UP LIFTERS!

    QUICK INSTALL PUSHRODS HAVE 7/16-20 THREADS PER INCH, 0.050 ADJUSTMENT PER TURN. 2 TURNS = 0.100

    TROUBLE SHOOTING NOISY VALVE-TRAIN
    1. Lifter adjustment - Starting with a fully pumped up lifter, from zero lash put 0.90 - 0.100 of pre-load on Feuling® hydraulic lifters
    2. Lifter to lifter bore clearance out of spec, Feuling® recommends a clearance of 0.001 - 0.0015 for proper oil psi at lifter
    3. Pushrods flexing and hitting pushrod tubes - look for a shiny ring witness mark around pushrod normally seen up towards the cylinder head
    4. Low oil pressure - inspect pressure relief valve in camplate, oil pump/camplate wear
    5. Pushrod center oil hole plugged
    6. Clearance for roller rocker arms on under side of rocker box covers
    7. Steep ramped camshafts, valves closing so fast the valves bounce off valve seats - see Feuling® Beehive® valve springs
    8. Excessive crankshaft runout
    9. Gear drive camshafts, excessive gear drive backlash or excessive crankshaft runout
    10. Rocker arms/bushings out of tolerance
    11. Valve spring clearance to lower rocker box housing
    12. Valve spring coil bind and or valve spring harmonics - match up valve spring open height with camshaft peak lift
    13. Leaky/broken piston cooling jets
