Diesel Engine Setting/Locking Tool Set Instructions
VS123.V2 Tool Set comprises the timing pins and specialised tensioner adjustment tools required for timing belt replacement on all the variants of the Rover 2.0 diesel engine fitted in MG-Rover, Land Rover and Honda models.
FLYWHEEL LOCKING PIN - VS170/1
VS170/1 Locking Pin is used to lock the crankshaft in its timed position. The pin is inserted through a hole in the gearbox mounting back plate and engages a corresponding hole in the flywheel.
INJECTION PUMP LOCKING PIN - VS120/1
VS120/1 Pin locates through a hole in the injection pump sprocket into a recess in the pump mounting flange to lock the injection pump in its timed position.
TENSIONER TOOL - TIMING BELT AUTOMATIC TENSIONER - VS1201
These ‘L Series’ engines require VS1201 to retract the automatic tensioner assembly during timing belt replacement applications. When removing the belt the tensioner nut is slackened and tensioner access plug removed to allow VS1201 to be fitted to pull back/retract the tensioner plunger.
TENSIONER ADJUSTER - INJECTION PUMP BELT AUTOMATIC TENSIONER - VS4739
On Rover 25 and 45 and MG ZR and ZS models the automatic tensioner on the injection pump drive belt requires VS4739 Adjuster to correctly set the tensioner position.
Note: Correct tensioner position varies and depends upon model.
Rover 25/45 up to 2001 usually set the tensioner pointer in line with the notch, whereas after 2001 and on MG models the requirement may be to position the pointer aligned to the lower edge of the tensioner backplate. Check workshop manual for the tensioner position of the specific model being worked on.
