5 Timing chain and sprockets - removal and refitting
1 Remove the air cleaner (Chapter 3).
2 Disconnect the battery negative lead.
3 Remove the radiator, drivebelt and fan (Chapter 2), and the spark
plugs (Chapter 4).
4 Remove the power steering and air conditioning compressor drivebelts
(Chapters 10 and 11) as applicable.
5 Pivot the alternator away from the engine.
6 Position the crankshaft with No 1 piston (rearmost) at TDC on the
compression stroke.
7 Release the wiring harness from the clips on the timing cover.
8 The crankshaft must now be locked, in order to unscrew the crankshaft
pulley nut. If the engine is in the vehicle, remove the gearbox front
cover, and use a wide-bladed screwdriver to lock the starter ring gear.
If the engine is removed, the starter ring gear may be locked using a
bolt and bent piece of metal (photo). If the sump is removed, use a block
of wood to jam the crankshaft.
9 Unscrew the crankshaft pulley nut, and slide the pulley from the nose
of the crankshaft (photos).
10 Unscrew the nuts and bolts, and remove the timing cover and
gasket (photos).
11 Remove the oil thrower from the crankshaft (photo).
12 Push the timing chain tensioner plunger fully into the body, then lock
it by inserting a small screwdriver in the hole. and turning the pawl
anti-clockwise (photo).
13 Unbolt and remove the timing chain tensioner, and extract the
tensioner oil filter from the block (photos).
14 Flatten the lockwasher and unscrew the bolts securing the camshaft
sprocket to the camshaft (photo).
15 Remove the camshaft sprocket, and release the timing chain from both
sprockets (photo).
16 Slide the crankshaft sprocket off, and remove the Woodruff key
(photos).
17 Clean the components, and check them for wear and damage. Wear in the
timing chain is indicated if it is deeply bowed when held horizontally.
Wear of the sprocket teeth is indicated if they are deeply undercut.
18 Commence refitting by pressing the Woodruff key squarely into the
crankshaft nose (photo).
19 Slide the sprocket fully onto the crankshaft and over the key. 20
Check that the crankshaft and camshaft are aligned as shown in Fig. 1.5.
Both the crankshaft sprocket mark and the camshaft bolt hole indicated
must be on the centre-line (photo). Reposition the camshaft and
crankshaft if necessary.
20 Check that the crankshaft and camshaft are aligned as shown in Fig.
1.5. Both the crankshaft sproket mark and the camshat bolt hole indicated
must be on the centre line (photo). Reposition the camshaft and
crankshaft if necessary.
21 Fit the timing chain to the camshaft sprocket, with the double white
reference marks either side of the mark on the sprocket (photo)
22 Engage the timing chain with the crankshaft sprocket, so that the
white reference mark is aligned with the mark on the sprocket (photo).
23 Fit the camshaft sprocket to the camshaft. then fit the lockwasher and
bolts. Tighten the bolts to the specified torque, and lock them by
bending the lockwasher onto the bolt flats (photos).
24 Insert the timing chain tensioner oil filter in the block.
25 Refit the timing chain tensioner, and tighten the bolts.
26 Check that the reference marks are correctly aligned. Release the
tensioner plunger by turning the pawl clockwise (photo).
27 Locate the oil thrower, and the Woodruff key for the crankshaft
pulley, on the crankshaft.
28 Position the gasket on the engine front plate. Refit the timing cover.
and hand-tighten the nuts and bolts.
29 The timing cover must now be centralised before refitting the
crankshaft pulley. Peugeot garages use a special tool for this purpose.
but the pulley may be used by wrapping adhesive tape around it (photo).
If the cover is not centralised correctly, oil may leak past the pulley,
or the pulley may emit noise.
30 Slide the pulley (taped) OntO the crankshaft (engaging the Woodruff
key) and into the timing cover, so that it holds the cover firmly.
31 Tighten the timing cover nuts and bolts to the specified torque
(photo).
32 Remove the pulley, peel off the tape, then refit it, taking care to
engage the Woodruff key in the pulley slot.
33 Fit the crankshaft pulley nut, and tighten to the specified torque
with the crankshaft locked as described in paragraph 8 (photo).
34 Clip the wiring harness to the timing cover.
35 Refit the power steering and air conditioning compressor drivebelts
(Chapters 10 and 11).
36 Refit the spark plugs (Chapter 4), and the drivebelt, fan, and
radiator (Chapter 2).
37 Reconnect the battery negative lead.
38 Refit the air cleaner (Chapter 3).

Hi
I'm sure this car has drum brakes all around. If they are way out of
adjustment, they have to travel too far before hitting the drum, using up
all the volume of brake fluid that the master cyl can deliver in one stroke.
I have had to replace faulty master cylinders to correct the same problem, I
guess they can leak internally and never generate enough pressure.
Be sure to get this fixed soon!
