small diameter dial test indicator to allow access to pumps that are obstructed by
the vacuum housing and fuel pipes.

• Dial test indicator: 41 x 8mm.

1. Unscrew the standard tip from the dial test
indicator and fix the correct extension in its
place.

2. The short extension (F) is used with the short
M8 adaptor (E), and the long extension (C) is
used with the long M8 adapter (A).

3. Select the correct length M8 adaptor and
attach the dial test indicator with extension.

4. Tighten the adaptor to the dial test indicator
shank by using the nut and secure. Some fuel
pumps have a M12 threaded port.

5. Item D can be fitted to either adaptor and
converts the M8 thread to M12 (see Fig 1).

6. Clean the fuel injection pump around the
service port.

7. Remove the plug and attach the adapter and
dial test indicator. You can turn the dial test
indicator to make it easy to read (see Fig 2).

8. Loosen the nut on the adapter to enable you
to bring the dial test indicator and extension
into contact with the pump plunger. This will
pre-load the dial test indicator by
approximately 1mm.

9. Tighten the nut to prevent the indicator
sliding within the adapter.

10. Zero the dial test indicator bezel and lock it in
position with the thumbscrew.

11. Turn the crankshaft backwards until the
pointer on the dial test indicator stops
moving. Check that the small scale on the
face of the dial test indicator shows a 1mm
pre-load and re-zero the bezel.

12. Turn the crankshaft forward to the static
timing point and compare the reading on the
dial test indicator with the manufacturer’s
specified timing data.

13. When the reading is correct, remove the dial
test indicator, adapter and any extensions.
