I've been reading about and locating a replacement Quartz clock for my 1968/69 Rally Tic Toc Tach. What I've found is that a S 3105 should be the right replacement if the original is a "Borg".

Before I try next how to continue disassembly can someone tell me if this unit is a "Borg"? and how do you remove the clock hands?

Any help is appreciated, I'd like to do this myself rather than put it back together and send it away, but I'll send it off if it's too hard to continue.

 

I found another thread here with a link to good info. The hands pull off, but boy does it take some pressure. I see nothing that tells me that it's a borg, but doesn't it almost have to be? - Steven

 

My std clock was stamped Borg on the back of the case

 

My clock case isn't. It only has the number 0958.
I'd like to confirm it's a borg before I order the Quartz replacement.

 

The two major (only) suppliers of clocks were Borg and Westclox. You might try to see if yours matches with anything you can find on the net re: Westclox?

 

The net isn't helping me so far, I tried the only number located on the back of the clock (0958) along with Westclox and with Borg and come up with nothing, but thank you Dave for the Westclox lead and confirmation that there was more than just Borg manufacturing the clocks. - Steven

here is a pic of the back of my std clock (not TTT)

there is also a ink stamp that says 2879

Mine doesn't have any kind of marking. One seller of the S-3105 Quartz Clock says it fits 1968 Tic Toc Tachs and the one I own was certainly built in April of 68 so it should work. I'm thinking I better go ahead and order the clock and install it while I still remember how it goes together!

Thank you for the picture.

I bought a replacement NOS clock to go in my 72 tic toc tach mostly because I like the sweep feature, which the quartz ones don't have. So I'll be doing that in the summer. It'll be nice to have a clock with a working second hand. Personally I really don't care if it keeps time or not, just so long as it works. BTW, there is a procedure for speeding up the clock and slowing it down. Check your owners manual or CSM, I think you advance the clock to increase speed, and wind it backwards to slow it down. ???

re: how to take off the hands. I think I'm right on this, but see if anyone else can confirm. This past summer I took apart the speedo on a 71 CS and it has the needle pressed on pretty much like your clock hands. I remembered reading somewhere that they were just pressed onto the center shaft so I pulled straight up on the center of the needle hub and it came right off. After playing with the speedo, I reassembled it just to see how it would go together and putting the needle on was a simple press on. Hope it's the same for your clock. I realize how nervous it can be when you don't want to screw it up, so maybe find a spare old clock or speedo at the boneyard to 'feel' the kind of upward pressure you need. It's not a lot, but it's not overly delicate either.

 

Thanks Alan,
The hands did pull off. The second hand was super tight on mine, the minutes and hours were easy. Drain on the battery while sitting and accuracy pushes me towards the Quartz. I recall my grandfather saying that any quartz watch is a good watch.

 

I agree that the quartz will be more accurate and less voltage draw. But the clock draws so little voltage it's hardly parasitic enough to sneeze at. If you're worried about during storage? Disconnect the battery or use a battery tender.

Good luck on the rebuild, be sure to keep the thread updated on the progress?

 

Do not know if it has been mentioned, or is a concern for you, but a quartz replacement is immediately noticeable to even the untrained eye.

That is because the second hand moves in a continuous smooth motion. The old clock has a second hand that moves in discernable, discrete ticks.

 

Where can you get the kit ? In another clock thread I posted a link to a you tube vid I'll see if I can find it

 

I have always bought my quartz movements from Instrument Services. They can probably help identify the clock also. www.instrumentservices.com

 

I sent in two clocks for my Corvette, had one restored and one converted to quartz. The quartz clock has been in the car now for about 8-9 years, keeps perfect time. I love it, its not an all original car so i dont care if the second hand is incremental or not. Im saving the restored one.

 

here it is nother clock thread w rebuild link

 

I had one converted to quartz. I never had the car when it worked, so I don't miss the ticking movement. It does drain the battery, so I disconnect it when I park it for a while and reset the clock when going to shows. Other times, I just let it run at the wrong time.

 

Most of the time the clock stops running because the gear lubrication becomes to thick. Sort of like the power window grease - it needs to be cleaned out and renewed. Clocks don't need grease though - they use light machine oil. So a good cleaning to get rid of the accumulated crud and a light coating of machine oil you should be good to go.

 

This is an e-bay listing by Instrument Services.
It might be cheaper to contact them directly so there aren't e-bay/paypal fees. - Steven

I bought one of the S-3015 Quartz kits. I'll post my experience here regarding how it goes together. - Steven

 

There was one modification I had to perform to switch out to the quartz clock that the parts were not included in the kit. The power post on the clock was larger on the replacement and wouldn't accept the original ring terminal. The solderless ring terminal and new nut to fit the post amount to less than a dollar at the hardware store.

 

In Summary the kit was easy to put together. It came with a DVD showing the steps and it required a minimum of common tools. - Steven
