The document discusses a modification to the rod head assembly which improves force distribution at the rocker arms, enhancing performance and reducing the risk of breakage. Loesche offers a conversion kit that allows for in-situ installation, promising a return on investment of less than one year. The modification features a new rod head bearing design that optimizes grease flow and load positioning for better efficiency and longevity.

ROD HEAD ASSEMBLY MODIFICATION
BETTER DISTRIBUTION OF FORCES AT ROCKER ARMS

2. Key features rod head bearing modification
The new rod head bearing design allows a better distribution of the loads as well as a
reduction of dynamic forces experienced by the bearing, thus almost eliminating the risk
of a breakage of the rod head. The grease flows by gravity in the contact area where the
movement takes place and the loadzone is situated.
Loesche offers a conversion kit as a complete modification for the rod head assembly.

• Rod head
• Pin
• Set of installation parts
• Set turned components for easy and quick installation in-situ
• Spherical roller bearings in the rod head replaced and not in use any more
(Pos. 3)
• 2 cylindrical roller bearings installed in side cheek of the fork of rocker arm
(Pos. 4)
• 1 plain spherical roller bearing for alignment implemented
• 2 cylindrical bearings installed at the fork of the rocker arm where the movement
takes place
• Loadzone with new rod head bearing kit has moved to the bottom where the
grease flows to
• Better distribution of the loads and bearings are greased where the loadzone
is located
N.B:
For a modification to the
original Module 30 it is
necessary to increase the
seating bore diameter in
the fork. This rework can
be accomplished with the
rocker arm in a workshop
or “in Situ” using a special
machine which can be
supplied by Loesche.
