Beogram 4002 bearing

[calman65]

Hello all, what are my options for replacing the spindle bearing on 4002 type 5513 . The platter seems to have to much side to side movement . The tt does play and I have recapped it .Thanks , James

Hi James, and welcome ?

This is absolutely normal for that bearing. It is a self-centering bearing with only one sintered ring at the top. It has a special thrust pad at the bottom.

Ok thanks ,   I don’t see the thrust pad . The spindle is convex and inside the main bearing is concave , there should also be a thrust pad ?

[chartz]

There is always one.

Do you know what the pad looks like, got a picture? The way the spindle fits into the bottom of the bearing on my 4002 seems to center it.

I was wrong about the inside of the main bearing. I got a better look, and it is flat with a small deep hole in the center. This small hole might center the spindle. I have not found any mention of the thrust pad yet. The spindle needs something to center it, or it will rub on the single sintered ring. Maybe the little hole?

I believe the confusion is due to the 4002 having two different bearings. The earlier 5503 types had the platter from the 4000 which had a ball and thrust pad. Yours is the later one which had a lighter but larger black subplatter  and only used a centered point. In any case, there does not appear to be anything missing.

Thanks Mark that explains it. I am working my way through Beolovers restored thread. I have yet to hear back from him on this.

Hi

Regarding to the confusion about the bearing maybe this gives a bit more light:

Kind regards

Christian, I’m afraid the 8002 had a different bearing yet again as it was a different drive system.

There is a special thrust pad with a hole and the spindle sits slightly over it. Late Beogram 4000´s had the same kind of bearing, only larger (12 mm if memory serves).

I’ve got two 4002 (not 4000’s) and I can’t see what the thrust pads are.

I want to add that one of the BG has a little play in the platter that do not impact playing records.

Can somebody say something relevant about these thrust pads that will not add more haze to the question?

[calman65]

matador read post#5604., My5513 type 4002 does not use the thrust pad and the “play” in the platter is normal. Its a self centering spindle.  During my pre-restore inspection I notice that the zero force balancing screw is loose , just as beolover said it would be .
