Hendrickson Leaf Spring
Assembly Inspecting
NOTE: See Fig. 7 for this procedure.
1. Inspect the spring hangers for wear of the spring
pin holes, cams, and the spring hanger legs.
2. If equipped with the "RTE" or "UE" series, the
gap between the rear (No. 2) spring hanger and
the top spring leaf should measure at least 3/8
inch (9.5 mm) in an unloaded condition.
If the measurement is less than 3/8 inch (9.5
mm), install new rear (No. 3) extension hangers.
Lubricate the bolt threads with SAE 20 oil.
Tighten the 1/2–13 locknuts with hardened
washers 85 lbf·ft (115 N·m).
3. Inspect the spring leaves for cracks, gouges,
wear, or abnormal bends. The no. 1 main and
no. 2 wrapper spring leaves (the top two spring
leaves) may be individually replaced. If equipped
with the "RTE" or "UE" series suspension, the
nos. 1, 2, and 3 spring leaves (the top three
spring leaves) may be individually replaced. If a
spring leaf is damaged below these numbers in a
pack, replace the spring assembly. In addition,
replace both spring assemblies to ensure even
spring deflection.
