4170 x 1 . XK120 Late  / XK140 / XK150 & C-Type etc. Lower Ball Pin Rebuild Kit with a equivalent modern nylon cup ( Ferrobestos deep cup shape) to replace either type of ball cup fitted.

This Kit includes our part numbers : 4110 & 4140 & 4150 & 4160)

NOTE : For earlier type with brass seat and steel spigot see kit : 4170B

To be fitted to correct Jauar Workshop Manual instruction. SEE : 9000

NOTE : The early O.E. type ball pin seat design was made from a 'newly' developed brass based material, known in the day as 'Morganite' ( made by Morgan Crucible Co. of Swansea) and a steel spigot locating ring that was factory fitted to XK120 and also late run XK150 (exact recorded data is vague). In the period between they used a deeper cup (with integral spigot) made of a compressed asbestos fibre material known as "Ferobestos" (made by Tenmat of Manchester) which we now replace with the nylon cup listed here which is a superior, modern alternative .

This may explain some original XK caps not having a grease nipple fitted, as it was not in the Ferrobestos materials design to require re-greasing. This differs from the earlier  design as a Morganite insert WILL require a grease nipple fitting to the securing cap if it is blank, SEE :  4313
