Carillo "H" replacement rod bolts
Material: L19
L19: This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260,000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels – L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.
Tensile strength: 260,000 psi
Installation Instructions
Part Number: 200-6203 & 200-6223
Application: CARILLO-REPL. FOR H-BOLT
Cap Screw without Washer - Rod Bolt Installation
[1]
Please check the part-number(s) for your application
against the part-number(s) listed on the instruction sheet.
[2]
Make sure there is an adequate chamfer around the bolt
hole on the connecting rod cap to clear the radius under
the head of the bolt.
[3]
Use ARP Ultra-Torque Fastener Assembly Lubricant
to lubricate the threads of the bolt and the under head of
the bolt. Then install the bolts and tighten them hand
tight.
[4]
ARP recommends using the STRETCH METHOD when
tightening rod bolts. Following the instructions for using a
stretch gauge, Stretch the bolts to . 0065 - . 0070 .
[5]
If you do not have a stretch gauge, torque the bolts to
_ 80 ft-lbs (108.5 Nm) using ARP Ultra-Torque Fastener
Assembly Lubricant.
[6]
The connecting rods should always be re-sized after new
rod bolts are installed.
[7]
A log should be kept on the original non-torqued length
of each bolt. Bolts that have any permanent deformation
or have increased in non-torqued length by more than
.001 in. should be replaced.
