SOLAR SPRING : MAINTENANCE
How to replace the piston bearings
Tools and materials required : Suggested piston support (901).Suggested spindle driver (904), vice, wooden or plastic mallet, liquid silicon or non toxic grease.
Introductory note
Bearings part 347 and axis rods 348 seldom require replacement. NEVER replace
part 347 without replacing part 348. As it is rather difficult to replace parts
347 and 348 without risk of damage to the piston (350) itself, replacement
of the whole piston group (346) is recommended.
Step one
Place the piston group in a vice with the axis rod (348) vertical with respect to the vice.
Step two
Use the spindle driver (904) and a mallet to knock the axis rod (348) as gently as possible through the piston body so as to release the axis rod (348) itself, the two bearing rings (349) and the vertical bearing (347)
(Drawing of bearing removal operation)
Step three
Rub a small amount of non toxic silicon grease on to the (eventually new) axis rod (348)
Step four
Place the axis rod (349) on the piston spindle driver tool (904) as shown in drawing fig. ###
(photo 04-0162)
Step five
Approach the rod (348) and spindle driver tool (904) to the piston (350) and place in vice as shown in drawing fig. ###
Step six
Make sure the rod (348) and the centre line of the piston (350) are in line with each other:
This is good :
Drawing showing correct alignment
This is NOT good
Drawing showing erroneous alignment
IMPORTANT : You will note that the axis rod (348) is curved at its extremities, so that when assembled its ends will be flush with the curved/rounded surface of the piston :

Step seven
Screw the vice until the free end of the axis rod (348) protrudes approximately one centimeter beyond the inner face of the piston (350).

Step eight
Insert the first space ring (349) on the protruding end of the axis rod (348)

Step nine
Insert the bearing (347) in line with the axis (348) and continue gently closing the vice, contemporaneously turning the bearing (347) with the fingers to enhance progress, until the axis (348) protrudes very slightly (a few millimeters is enough) from the free end of the bearing (347).
Note : The bearing should be turning freely at all moments.
Step ten
Hold the second spacer ring (349) with the free hand in line with the axis (348) and the piston (350)
(Drawing)
Step eleven
Continue turning the vice with one hand and the bearing (347) with the other hand, until the axis (348) is fully and correctly seated in the piston (350) and the external surfaces of the axis (348) and the piston (350) are flush with one another.
Step twelve
Check and make sure the bearing (347) is turning freely on its axis (348) inside the piston (350)
