According to the manual M51000 / M51100

'Maintenance Procedure', dismantle the fuel injection

pump from engine block, and disassemble the plunger

and barrel.

lnstallation of Teflon Ring

1. Check the installation tool of teflon ring of each

part [Rg.1l.

2. Heat up the teflon ring to 80-9011 for having

flexibility, if possible

3. Put the barrel on the protection jig not to fall

down during inserting teflon ring. lfig.2]

Fig 2

4. Set in the long sleeve on the barrel, [fig.3] and

insert the teflon ring on the sleeve. [fi9.4] The

direction of spring should be upside.

confimed.

5. lnput the expanding sleeve on the long sleeve,

and push the teflon ring to the lower groove on

the barrel. lfig.5,6l

6. After assembling the short sleeve on the barrel

lfig 7], input the teflon ring on the sleeve. [fig.g]

The direction of spring must be positioned

downward.

7. lnput the expanding sleeve on the short sleeve,

and push the teflon ring to the upper groove on

the barrel.

Be careful not to push the teflon ng with

the excessive force.

Holding the adjusting tools by hand lfig 12],

press the tools both sides to shrink the teflon

ring. lfig 13] Press the adjusting tools turning the

direction to fit the teflon ring on the groove.

L On the upper groove, do the same method of

shrinking the teflon ring.ffig.141

10. Assemble the adjusting shell for barrel with 4EA

of M12 bolts. Ighten the bolts by turns not to be

unbiased. (Reference : the clearance of adjusting

shell : 1mm)

11. After disassemble the adjusting shell, the

deformation of teflon ring can be occurred

lfig.18] lfig.19] Then repeat the 8-9 step to make

even surface on teflon ring.
