Re: Tire circumference with the illusion of speed and handling

Robert, if you recall the problem getting the standard Model A tires (475/500 x 19)on the rear axle, you will remember the difficulty was the getting thickest part of the tire past the gap between hub and lowest part of rear fender. Deflating the tire will sometimes do the trick. The firestones you ...

Re: Tire circumference with the illusion of speed and handling

Those Goodriches are meant to be installed on a 3.0-3.5 inch rim. Standard TC rim is 2.5 inch. Though the actual outside width of an original TC wheel is 3.7 inch, that is not how it is measured. Doubtful anybody would suggest it OK to put such fat tires on 2.5" rims. Or have you already got 3" rims...

Re: Tire circumference with the illusion of speed and handling

What size and brand tire is 31.4 inches? Such a tire would give you the equivalent of a 4.5:1 rear end. Interesting to note that circumference is not a stat tire makers ever mention.

Re: Tire circumference with the illusion of speed and handling

There are online calculators where you plug in tire diameter, rpm, mph and rear end ratio. Leave one field blank and it will calculate it for you. http://www.advanced-ev.com/Calculators/TireSize/ 4.75/5.00 x 19 tires these days commonly sold for Model A's run about 30 inches diameter. There is some ...

Re: TC9849 EXU Restoration

The casting date on my engine (10536) is "8 D9" or 8 April '49. Interesting 2 month spread for cars likely on the assembly line at the same time or one day apart.

Re: Brake light switch options?

Brake switch arcing can be greatly reduced by using a LED type bulb, which draws much less current.

Re: Brake light switch options?

I ended up using the original switch again, after a good cleaning and greasing. Works fine. Franz, on the TC the spring or link is attached directly to the pedal assembly, underneath the car.

Re: New springs alter TC rear axle location.

But Ray, are you not concerned about upsetting the delicate TC suspension geometry? Just kidding. But seriously, if you are going to use those springs you may want to confirm they were indeed intended (spring rate) for the TC, or real close. That link Steve S supplied tells how much weight standing ...

Not much to it. Those Silentbloc's come as a unit. Pointless to try and rebuild it. They run about $20 ea from the usual suspects

Re: New TC after driving cooling water boiling

New? If you overfill the radiator it will boil some out after it warms up and you shut off the engine, the first time. Quite often XPAG overheating caused by distributor advance not working right. Easy to check with a timing light. ;)

Re: TC Front springs.

For a bit different perspective on preserving leaf springs, see the first article here-- http://ttypes.org/ttt2/?s=leaf+springs&submit=Search An old hot-rodder trick to keep the grease in and weather out is to wrap the leaf spring assembly in Denso tape. Same effect as a leather gaiter. If you wrap ...

Re: more on rear leaf springs.

SteveW's idea of mixing graphite with grease is popular. Some prefer silicone grease. More than a few people think the whole notion of the teflon sheets is rubbish, as they do nothing to repel/displace water and dirt.

Re: Pinion diff bearing #18

Not sure where the incorrect size of 62 x 25 x 17 is coming from. #18 is a double row angular contact bearing of dimensions 62mm x 25mm x 1" (25.4mm).

Here is a couple pics of the known original R&M bearing. It had a single piece inner 2X race, and split outer race.
