EW Code PETROL ENGINES – Update Tools

EW 10 & EW12 Twin Camshaft Petrol Engines

– New engine variants – New tools required

- Refer to Application Chart for model usage / engine codes

PSA changed the method of 'locking' the ﬂ ywheel/crankshaft and ﬁ tted a different belt tensioner to some of the "EW Code" petrol engines from around 2002.

These engines tend to have only one bolt for the crankshaft pulley in place of the 4 x pulley bolts on previous engines. Locking the ﬂ ywheel requires NEW Pin

DT.4825P19 and the belt tensioner procedure demands New Tools DT4826-1 and DT.4826-2.

DT.4825P19 Flywheel Locking Pin

Turn the crankshaft to 'timed' position and insert New DT.4825P19 Locking Pin through the 'datum hole' in bell housing and in to the ﬂ ywheel.

NOTE: Previously, EW engines used DT.4575P11 Crankshaft Locking Pin from DT.PSA Kit, through the crankshaft pulley ﬂ ange to 'lock' the crankshaft.

IMPORTANT: DT4825P19 Locking Pin will not enter as deep in to the hole on Automatic Transmissions as it does on Manual Transmissions.–see diagram 22

– "A" = Manual Transmission / "B" = Automatic Transmission

Use existing Camshaft Locking Pins from DT.PSA Kit - DT.4575P10 (pair), (or 1 x DT.4575P10 and DT.4575P14 for HPi), to 'lock camshafts and slacken

tensioner bolt to remove belt.

DT.4826-1 Belt Tensioner Turning Tool & DT.4826-2 Belt Tensioner Locking Tool

Place DT.4826-1 Turning Tool over the tensioner roller and locate on to the pointer. Turn DT.4826-1 clockwise until the 'pointer passes both the 'notch' and the

'slot' on the tensioner back plate.

Fit DT.4826-2 Locking Tool in to the 'slot' in the back plate to 'lock' the pointer in place,

and remove DT.4826-1 Tool.

Whilst retaining a new belt on to crankshaft gear using DT.4569 Belt Clip (from DT.PSA Kit), continue to ﬁ t the belt in anti-clockwise direction.

Fit crankshaft pulley and remove Locking Pin from Exhaust sprocket, DT.4569 Clip and DT.4826-2 Tensioner Tool.

Tensioner position

Using an Allen Key turn tensioner anti-clockwise at Hex. "A" until pointer achieves position "B" - POINTER MUST PASS 'NOTCH' BY T LEAST 10° – or replace

tensioner.

Turn tensioner clockwise to align the pointer with the 'notch' "C" – DO NOT TO PASS 'NOTCH' "C"

Tighten tensioner bolt – DO NOT allow tensioner to turn whilst tightening the bolt.

The Allen Key Hex "A" position – MUST BE 15° BELOW CYLINDER HEAD GASKET LINE – or replace tensioner.

Remove remaining Timing tools and turn crankshaft 10 turns, by hand, clockwise, returning to 'timing' position.

Check Tensioner Position

Insert Locking Pin into Inlet Camshaft sprocket – check that the tensioner pointer is aligned with the 'notch' – If pointer passes 'notch' "C" – repeat the

tensioning procedure.
