So far so good, nothing has stripped or broken yet!

This will be an interesting thread, thanks for posting!

Hello !

3- ready for field test

back-up whasher( rubber) top
o-ring bottom
(make sure they are not twisted)

Image

back-up whasher( rubber) top
o-ring bottom
(make sure they are not twisted)


Image
Image

cylinder wiper

Image

rod-guide back on shaft

Image

back-up whasher towards threads
then o-ring
(make sure they are not twisted)

Image
Image


Image
Image
Image

large seal first V shape toward flange
the last seal has a flat back shape (so it seals when we put back the piston) opposing to the others that has a groved shape so they fit togehter

Image
Image
Image
Image
Image
Image

rod-guide back on the shaft

Image

O-ring (make sure it is not twisted)

Image
Image

piston

Image
Image

nut back on ( torque according to whish cylinder you do)

Image
Image


rod and rod-guide back into the cylinder


Image

push down the rod-guide far enough to be able to insert the snap ring ( not too far cause you need to put back the lock nut and you need threads on the ro-guide head to do so )

Image
Image
Image

you are then ready to test an then re-install !!
