Hydraulic Lifter Update On
GM 4.1L (252 CID) HT-4100 Engines
A revised hydraulic lifter assembly has been released by General
Motors for the 4.1L (252 CID) HT-4100 engine used exclusively in
Cadillac automobiles.
The revised lifter assembly carries part #5234360 and features a
revised foot radius for improved service life. It replaces
lifter #5234235 for this engine only. The former lifter should
be used for the current 6.0L (368 CID) engine and all past model
V-8 gasoline engines used after 1968. Whenever lifter
replacement is called for on 4.1L (252 CID) engines, the new part
number should be substituted.
Aftermarket manufacturers have followed suit and offer the
revised component under the following part numbers.
Dana 213-1685
Pioneer Barnes VT-969
Sealed Power HT-969
TRW VL-73
Check with your aftermarket parts warehouse or distributor for
additional part numbers.
The illustrations below feature a representative aftermarket design of
the lifter. However, the ribs are simply used for identification and
may appear in different locations depending on manufacturer.
