Replace pitch control belts on BIC 914C

Picked up this 914C with ADC cart for $5. Got it up and running except the pitch control. It has 2 rubber belts that are broke, running from the front thumb wheel to a 2 pulley shaft to a pulley at the bottom of the motor. One of the motor mounting bolts runs through the belt. Anyone familiar how to take it apart to replace the belts. I managed to reach a finger in and adjust the motor pitch. Seems to be a decent table. Removable tone arm shaft. Nice heavy platter and not bad sound. :scratch2:

My first thought was "cheap made". I had the 960 & 980 and liked them. But 914C does have a removable arm tube, adjustable head shell angle, fairly hefty platter. Not bad. When took the top of and was surprised that it looked fairly substantial under the skin. The 2 belts for the pitch control were broke and laying on the bottom pan. Was able to adjust the pitch pulley with my finger. Re-greased the platter bearing. Only had the stacker spindle, would a short spindle from another BIC table work. Got it working. Popped a Grado on and it doesn't sound bad at all. Now the question, If I get new belts, how do you raise the top pan to get clearance to install the new belts? Also the top plinth begs for a re-do. I could ether paint it or give it a wood veneer. Cool. :thmbsp:

I have to get to bed to get up for work at 4 am so I will write more tomorrow but the base plate with the platter/changer mechanism on it lifts from the bottom pan after you remove the four clips which look kind of like cotter keys from the four posts which extend up through the plate from the bottom.

You have to detach the ground lead attached to the motor mount and maybe some other things. It's been a while since I had my 912C apart. You will see what else needs to be detached or whatever as you raise the plate.

The motor stays with the bottom pan and be careful of the strobe mirror/adjustment knob assembly as you remove the plate.

Thanks Doug. Looking at it I thought that might be were I needed to start but was not sure what else might have to be unhooked or moved.
 
OK, here's the real way to remove the chassis from the bottom pan after the top cover is off. :D

If the unit is an earlier one, the green grouind wire I mentioned above will be there and must be disconnected. Later units have the ground wire attached to the terminal strip underneath.

Since the speed change cam is mounted on the motor mount which stays with the bottom pan, the speed change lever must be disconnected which is done by slightly raising the cam and pulling the lever off from the bottom.

The four clips holding the chassis onto the bottom pan are not like cotter keys or anything like that at all. They are "E" clips or are sometimes called "C" clips. So much for my memory. :D Remove these and the chassis will lift up.

As you lift the chassis, on earlier units, there are three spade plugs which must be disconnected from the terminal strip. Note where they connect. I believe later units have a keyed plug inline which just needs to be unplugged instead of the three separate spades.

The chassis should now be free from the bottom pan.

Gary, yours looks like a later unit going by the cue lever but who knows exactly when BIC made the changes. In the PM, I mentioned I thought the pitch change belts are round but the long one is toothed. A flat one tight enough may work OK.

Also, my last instruction about being careful of the strobe mirror/adjustment knob assemblies is nuts too. That is during the top removal which you, obviously have already done. :D

Just received the 2 pitch belts from South Street Service Inc. There are 4 e-clips that need to be removed so you can lift the top plate to get at the motor. Not hard at all. Just take care. Did it in about 1/2 hr. I also repainted the plinth (hated the plastic gun metal look). Having a new cover made. Installed a Pickering VSP-3003 cart. I think it's not a bad table at all. I'll have to remove the top again, I forgot to feed the arm lift lever through, DUH!

OK, I'm finally able to reply after getting back online after a month-and-a-half!

Good deal and it's looking good too!

What you said about the cue lever. I did that once too. :D
