D553 Diesel Injection Pump Remover/Installer and
Sprocket Retainer
D553 Pump Remover/Installer & Sprocket Retaining
Tool covers 'Distributor Type' injection and HP pump
removal and installation on BMW models with
M47/M47TU and M57/M57TU engines.
The main purpose of this tool is to retain the position
of the pump sprocket in-situ, whilst the pump is
removed and off the engine. This allows the front
sprockets/timing chain configuration to remain
undisturbed and under tension, thus reducing the level
of engine dis-assembly required.
High Pressure (Common Rail) Pump
If a HP pump is fitted the position of the pump does
not affect the valve timing.
M47 with 'Distributor Type' Injection Pump
It will be necessary to lock the crankshaft at TDC No.1
cylinder using D146-2 Pin. Check that the lug on the
inlet camshaft, at No. 1 cylinder, points upwards, when
viewed through the oil filler hole. The injection pump
must be 'locked' with its locking screw to secure the
pump shaft before removing the pump.
NOTE: For this configuration of M47 with 'Distribution
Type' pumps, the Support Sleeve of D553 will not be
required.
The 'Distributor Type' pump will require timing when it
is re-fitted.
Remove the large blanking plug in the timing cover to
provide access to the pump sprocket centre nut.
Release and remove the sprocket centre nut
Screw in the D553 Support Sleeve in to the blanking
plug thread in the timing cover (not applicable to M47
engines with 'Distributor Type' pumps).
Slide the D553 Adaptor (without the Force Screw
fitted), through the Support Sleeve and screw it on to
the pump sprocket.
Screw in the Force Screw to release the sprocket from
the tapered shaft.
WARNING: The D553 Tool MUST now remain in
situ in order to maintain the pump sprocket
position with the pump removed.
