[Mgs] Poly Bushings

[Paul Hunt]

If the bushes are a snug fit over the pin then no, as the shoulder on the 
pin acts as the 'distance tube'.  Neither the Workshop Manual or the Parts 
Catalogue show a tube separate to the bushes, unlike the distance tube for 
the bottom trunnion.  So if the poly bushes need one it should have been 
supplied.  In my experience the tube rusts solidly onto the pin, which needs 
cutting through inside both arms of the damper, and even then some force to 
get the remains out of the trunnion, which then needs a fitting-kit for 
reassembly.  Watch these, as for many years the special pin was supplied 
with a Nyloc nut, which is totally wrong for the application as the end of 
the pin doesn't even reach the end of the nut, let alone have the required 
three threads minimum sticking through.  It needs a castellated nut, and a 
low-profile one at that.
