Beogram 4002 (5513): Another Beogram from Houston

The Beogram 4002 Type 5513 is turning out to be a popular Beogram in Houston.
Here is the initial assessment of another one in need of restoration.

The dust cover is functional and can be kept for now as the supply of newly manufactured Beogram 400x dust covers have become scarce for the moment.

Cosmetically this Beogram clearly has a problem with the condition of the keypad buttons.

On the bright side...the wood trim on this unit is in great condition.
The deck panels, platter and tangential arm assembly also look good.

This keypad though, will need replacing.

The rim of the sub-platter has some sort of residue on it.  I will try to clean that off.

Inside the Beogram 4002 cabinet is pretty typical.
There is debris from the disintegrated transport lock bushings everywhere.

The photo shows the DC platter motor already removed.  I already extracted the platter motor and sent it to Beolover for restoration.

Here is a picture of the Beogram 4002 cabinet with most of the components removed.
I will vacuum the cabinet base out to get rid of all of the loose debris.

Here are the removed components.

The floating turntable chassis, boards, control panel and display panel.

The two boards (main board and output audio signal board) look normal...and ready for restoration.

I opened up the servo motor case to check what the damping material looked like.  Often the foam padding is deteriorated and crumbling into little pieces.
This one is still intact and fine.

I removed the arm lowering damper for cleaning.  It also looks it good shape.

Here is the tangential arm tracking detection sensor opened up.  It will be replaced with a Beolover replacement part.

The SO (stop) and ES (end stop) switches look to be in good physical condition.  They will be functionally tested later along with the arm position sensor and infrared lamp.

The tangential arm assembly itself appears to be in good condition too.

While I have everything apart I will clean and lubricate where necessary and perform some early service manual adjustments.

Other restoration tasks will be electronic restoration work on the two circuit boards, switch contact cleaning.
