Bottom Rotators
The current configuration of the ASET™ engine
uses a bottom valve rotator installed under the
valve springs. Removal of the bottom inlet and
the exhaust valve rotators requires the use of tool
J 29294-B.

(Current Design — Mid-2003 and Later)
Tip-End Rotators
ASET™ engines used a tip-end valve rotator
installed at the top of the valve springs until
approximately mid 2003 (Figure 243). Removal of
the “tip-end” inlet and the exhaust valve rotators
requires the use of tool J 43887.

Figure 243 — Valve Spring, Rotator and Valve Seats
(Non-Current Design — Prior to Mid-2003)
The inlet and exhaust valve rotators are different.
The rotators installed on the exhaust valves are
stepped to accommodate the dual-spring
arrangement used at the exhaust locations. The
exhaust rotator contains a second level which
supports the inner spring used on exhaust valves;
the inlet rotator contains only a single level. This
difference is shown in Figure 244.
