You should shoot the idiots who converted it. In the meantime you may be able to access the grease nipple from beneath, it will be difficult and will be easier if you remove the sound baffle from under the cab floor in the offside wheel arch. The nipple is situated in the linkage relay pivot which is just a little aft of the injection pump. I suggest you obtain a spray can of chain lube or open gear lube and spray around the detent ball at the relay, you wiil see three holes adjacent the pivot, and spray the joint at the forward end of the linkage. The gearstick pivot may be accessed by removing the boot in the cab, engine oil is best here working the gearstick as you do it. When you have dealt with the imbeciles who built over the cab you need to bury them at least 20 feet deep to ensure they dont do it again. For your next horsebox, insist the cab can be tipped for maintenance. Good luck and dont take any prisonsers!!
