Model T Ford Forum: Forum 2016: Gearing.....
Top of pagePrevious messageNext messageBottom of page Link to this message  By Chris Otto on Wednesday, June 15, 2016 - 02:52 pm:

The rundown:
TT closed cab on a T chassis with 21" wire wheels. A Warford will be in use. Only upgrades to engine are a distributor and aluminum head.
Yes, lots of hills in my adventures.
What rear gear would most of you run?
I was thinking of going to the 3.00:1.
With the use of the Warford, would is be wiser to stay with the 3.63:1?
Any one running a Warford tell me what gear you are running and your experience?
I only want to build the rear-end once if I can help it.

Thanks

If you are referring to a new Warford which provides a high and low gear, stay with the 3.63:1.
If you are referring to an original style, it will depend on what ratios it provides. I will advise the unless heavily modified the original warfords can be very noisy with an enclosed vehicle.

Based on your description I would go with 4-1 gears. The Warford in OD will give you a decent "road gear". As you plan to drive lots of hills, this way you won't always be using low pedal and you will get better engine braking
Remember the old truckers rule, same gear down hill as you would use going up!!

I actually have 2. Both of them are the cast iron housing Warfords. From what I understand, 1st gear (underdrive) ratio of 1.37:1, 2nd (Direct) was 1:1 and 3rd (overdrive) was 1:1.363.

Les, I'm all trucker. I've had my CDL for 23 years now.

I run an aluminum case Warford with a 4 to 1. I wouldn't go to a 3.63 to 1 with what you have described. I agree with Les. Your motor will work pretty hard with the 4 to 1.

3:1 would not be the way to go. That cab is heavy and presents a lot of vertical square footage and wind resistance. With your Warford you have overdrive for higher speeds. They have a rather deep underdrive so I think the stock 3.63 gears would be good, you would easily be capable of over 50 mph. 4:1 would be more reduction than you need.

I use a 3:63 rear with a 3 speed repo warford. Works perfect. Would not suggest a 3:00 rear unless it's match with a u/d. Just my thoughts. J.

One of the speedsters I used to have had a Universal (the brand name, made strictly for a model T) three speed progressive shift with a really tall overdrive. It was intended for use with 4 to 1 rear end gears. Now, this was a light weight and low wind resistance car. It did just fine around town in direct, with the 4 to 1 gears. The overdrive gave it really good highway gears. For a closed-cab pickup? That should be perfect with a Warford overdrive.
Drive carefully, and enjoy, W2

Thanks guys for your input. With the suggestions here and chatting with a fellow T friend, it looks like I'm going to go with the 4:1.

That warford is going to drive you out of your mind in that closed cab. I speak from experience.

A good pair of ear plugs helps!!

Yea, I agree that it should be interesting. I haven't heard one in person, only in a couple of videos

I would be interested to see (hear) what differences a T chassis and running gear would make for
the colossal "drum" that is a TT closed cab, as opposed to the usual TT chassis/drivetrain.

I would also submit that the closed cab has all the aerodynamic qualities of a parachute, which
exponentially increases wind resistance as speeds increase. This should be a consideration when
calculating power/gearing formulas.

I cut my interior "roar" by 50% when I made some soft foam door bumpers to replace the originals
that had shriveled to "rocks", that the doors were rattling against. I suspect with my new balanced
drivetrain vibration-related noise will be further reduced, but that install is still a little way out.

Is a disturbutor an upgrade? :-)

My cab isn't in the best of shape. Which is good for me as I plan to modify it a bit. But I agree, it has the aerodynamics of a brick.

Anyone know what a closed cab weighs?
