Maintenance
 | In
Feb 2005 the rear axle needed replacing. Fortunately Polly model engineering still
use the original Clarke casting for the wheels & quartering of this old Polly
1, so I only had to replace the rear axle assembly. |  |
Now Then - Have a look at this, click picture to enlarge.
This is (was)
the rear axle assembly, thanks to Sim breaking it down for me we can now see what
was going on ! The axle end at the bottom of the picture shows heavy wear and
the axle box on the right was also an interesting egg shape. It is interesting
that the new axle box now comes with a much larger counterbored hole for the oil
reservoir on the axle box. |  |
In March 2005, Refurbished the cylinders, replaced the cylinder 'O' rings and
stripped down the motion to reduce slop. Re-timed the motion to cylinders and
hopefully sorted out the last of the niggles !! December 2005 - right hand
'O' Ring leaking. Replaced both 'O' Rings to main cylinders. Has been running
almost every weekend this year. | Polly
