My HL135 input pinion bearing gave up. Shocked by the £135 for 3 new pinion bearings!   So had a go fixing them.  
Removed all three pinion bearings with heat and various ways to pull them.   I found an electric paint gun better than a blowtorch which heated the case to much.   None came out with a “tap on a block of wood” as the pdf describes!  Once out dismantled the pinions with a suitable sized punch and heat.   Measured the bearings and ordered them from “simply bearings”.   (Excellent service as usual).  (4 bearings of size

id 12* od 28* width 8mm, 2 bearings of size id 9 od 24 width 7mm).  All metal shielded.   Total £16.       Easy to instal new bearings and rebuild pinions.  Then reseat pinions in gearbox and cutter head.    All worked fine.   Took several hours, mainly getting the pinions out without breaking anything.
