New 1000 Series
To assemble Operation 4-10
1 Clean the bore of the small end bush and lubricate it with clean engine lubricating oil.
2 Fit a new circlip in the circlip groove of one of the gudgeon pin bosses. Ensure that it fits correctly in the
groove.
3 With the piston upside down, put the connecting rod in position with the recess for the location of the big end
bearing (B1) on the same side as the recess in the gudgeon pin boss (B2). If the original piston is used, ensure
that it is assembled to the correct connecting rod and is used in the original cylinder. If a new connecting rod
is fitted, ensure that it is of the correct length grade, see Operation 4-11.
4 Lubricate the gudgeon pin bosses with clean engine lubricating oil and push in the gudgeon pin towards the
circlip. If the gudgeon pin is a tight fit in the piston, heat the piston to 40/50 °C (100/120 °F) before the gudgeon
pin is fitted.
5 Fit a new circlip in the groove in the other gudgeon pin boss. Ensure that it fits correctly in the groove.
6 Fit the piston rings, see Operation 4-8.
