Re: preload on the bearings

The only spec I've found, and that was in the Model T Service Bulletins, was for the "TT" worm drive. It said the worm drive shaft should not be assembled unless there is from .006 to .015 clearance between the washer and bearing. I'd probably install the rear cap and check the front-back end play a...

Re: Tire recommendations?

I just bought a set of Lucas because they had a nice "truck tire" look to them. Unfortunately they are just available in the 6.00X20 size. That's OK, but single rear wheeled trucks should use 6.50X20 on the rear. Dual rear wheeled trucks are OK with the 6.00X20 all the way around. Maybe if enough pe...

Re: What oil to use in the worm drive rear

I'd double check with the vendor and ask him for the specs on the oil he is repackaging. It must say that it is compatible with brass and bronze components. Many modern automotive gear lubes have anti-wear additives that are not. It's easier to find the correct lube for worm drive applications in th...

Re: BB 5:17 gears fit in 31 AA low speed axle?

Dave, first the 30-31 low speed gearing is a 6.6 ratio for the bevel gear rear. I believe physically the BB 5.17 gearing will fit in the AA housing, but the pinion shaft has larger spline diameter and won't fit the AA driveshaft coupling. Like Bob said, changes would have to be done to the driveshaf...

Re: early 28 worm drive

According to the Indianapolis Service Letters, there seemed to be a lot of trouble with the worm drive thrust bearings. In October 5, 1928 letter it mentions the changeover from the TT style worm thrust bearing, retainer, and collar (part numbers TT-114 and TT-123) as used on the "TT" trucks to the ...

Re: Tires

Originally the '28 AA's came with 30X5 high pressure tires in the front and 32X6 high pressure tires on the rear. In July 1929 6.00X20 balloon tires became standard on the front, but 32X6 high pressure were still used on the rears. Beginning January 1930 6.00X20 balloon tires were used for dual rear...

Re: 4 speed in 1929 aa

On the Warner produced 4-speed the casting date on the case is on the drivers side a little bit behind the clutch/brake pedal shaft area. The top transmission cover has a date on the passenger side behind the hand brake mount area, viewed from the top. There is also a date stamped on the transmissio...

Re: Front end caster

Have you checked the radius rod ball fit at the flywheel housing? Make sure the ball is round, fits tight in the cap, and that the cap is assembled correctly. If the ball is loose it can cause a front end problem. Also, I worked on a fellows truck that one of the rear spring center bolts were bent. ...

Re: Cast iron drums and other brake questions

The rule was to use woven lining on the steel drums and the molded lining on the cast drums, although the woven could be used on the cast drums also, but not visa versa. The molded lining sends the heat out to the drums, but the cast drums don't expand like a steel drum would. The woven lining usual...

Re: Part # or Plug?

It's not a big job to remove the six bolts that hold the coupling shaft outer cover to the back of the transmission, and then slide the cover back. The coupling shaft has a female cup with teeth on the inside. The transmission output shaft has a male gear on it that has teeth on the outside. These s...

Re: Part # or Plug?

I'd remove the bolts and slide the front coupling shaft cover back to inspect the coupling shaft to transmission output shaft gear connection (shown in your bottom picture). Often these get very worn out and can cause the backlash you feel. If it completely fails, it could leave you sitting along th...

Re: 4 speed Transmission counter shaft question

I'm looking at having a batch of these made, because I haven't been able to find any of these either. I'm waiting for the machine shop to get back to me with a price to see if the project is do-able. I forget what the Rockwell hardness the shaft has to be to withstand the use of needle bearings on i...

Re: New to the Forum

Some "BB" parts do interchange, but the majority of them do not. For instance, the internal transmissions gears are the same, but the case is different. The wheel bearings, brake shoes, front drum/hub assembly are the same, but the rear hub/drum assembly is different. The driveshaft, torque tube, an...
