I wrapped up the floating chassis component tasks by reassembling the tangential arm assembly.
During the reassembly I performed some key lubrication tasks like new PMX - 200 silicone fluid in the lowering damper and a mixture of Rocol MTS 2000 grease with Mobile NUTO H32 oil.
More modern lubricants are available today but I have plenty of the original lubricants called for in the Beogram 4004 service manual so I like to use those.
I applied some Molykote DX paste (grease) to the two tangential arm assembly rails first.
Then I opened the tonearm lowering damper to clean it and apply some PMX - 200 silicone fluid.
Next I mixed some Nuto H32 oil with Rocol MTS grease for the lubrication mixture on the tangential arm assembly spindle.
The parts are easy to get to so it is a good place to calibrate the tracking force.
