Evolution of Scott Tailwheels.doc Evolution of Scott Tailwheels The earliest known Scott Tailwheels were the CST-12 and 3-21. Nothing is known about them except they were replaced by the 3000 Series Scott Tailwheels. It is possible the 3-21 was a steerable, non-swiveling tailwheel. 3000-A1 - Double arm fork, solid rubber tire, and Steerable. 3000-B2-Same as above except full-swivel. There is one major distinguishing feature between the 3000-A1 and -B2 tailwheels. The 2077 style casting which mounts the 3000-B2 assembly to the leaf springs has two quarter round protrusions pointing up on the forward end of the casting. These protrusions will engage the steering arm when the tailwheel is turned beyond about 45° left or right of center. Having engaged the steering arm, it will allow the tailwheel to caster and go into full-swivel. The earlier 3000-A1 series lack these protrusions, thus making a non-swiveling assembly. 3-24B - Single arm fork, solid rubber tire, Steerable and full-swivel. Used on many older Pipers, Cessnas, Taylorcrafts and other light aircraft. Bracket was 1 ½" wide. A spacer was required for use with 1 1/4" springs. 3-24BS Same tailwheel as 3-24B but bracket was 1 3/4" wide for use on Stinson 108 Series aircraft. - 2000 This is a later designation for the 3-24B & 3-24B-1 tailwheels. The 3-24B and the 2000 are identical in appearance. 3200 - 8 inch double arm fork, Steerable, full-swivel tailwheel with an 8" pneumatic tire. Replacement for the earlier 3000 series tailwheels. Machined for 1 3/4" leaf springs. Spacers required for 1 ¼” and 1 ½” leaf springs. 3200 3200-1 3200-3 | 3200-5 1 hole attach bracket X X 2 hole attach bracket X No wheel and tire X X No wheel/tire/axle 3250 Same as 3200 except has an "A" frame bracket used to attach the tailwheel on the Swift series aircraft 3400-1 Same as 3200 except attach bracket is configured to use a 7/8” tubular spring mount as used on Cessna 180 series aircraft. 3400 Same as the 3400-1 except less wheel, tire and tube. The 3425 Series tailwheels are a steerable heavy duty tailwheel for tubular mount for either 15/16" or 1" tube spring mount. They may or may not have a locking mechanism. The steering are is straight. This series uses either an 8" or 10" wheel. The forks are different on these assemblies depending on tire size. These tailwheels are used most commonly on the Cessna 180/185 series aircraft. 3425-1 3425-3 3425-5 3425-7 3425-13 3425-15 3425-17 8" tire/wheel fork X X X ✗ 10" tire/wheel fork X X X Locking type X X X X ✗ 15/16" mount X X X X 1" mount X X X No wheel/tire/axle X 3450 Series tailwheels are similar in design to the 3400 and 3425 tailwheels. Steerable, full- swivel tailwheel that has no provision for locking. They use only the 10” pneumatic tire. They are to be used with a 15/16" or 1" tubular tailspring. The exception is the 3450-23 which has a bracket for leaf springs. The steering arms are also available in straight type or bent upwards. 3450-1 3450-3 3450-5 3450-7 3450-17 3450-23 Straight steering arm X X Χ X Bent up steering arm X Χ 15/16" mount X X 1" mount X Leaf spring mount X No wheel/tire/axle X 'X Manufacturers and Distributors INSTALLATION KITS FOR 3-24B TAIL WHEEL ASSEMBLIES Installation kits listed below include all the necessary parts for installing the Scott 3-24B Tail Wheel Assembly on the aircraft models indicated.

SECTION INTRODUCTION This Handbook is issued as the basic technical instructions for the Models 3-24B, 3-24BB and 3-24BS Automatic, Full-Swivel & Steer- able Tail Wheel Assemblies. This Handbook contains descriptive data and instructions for the installation, operation, maintenanco and overhaul of the above-mentioned equipment. 2. A group assembly parts' list and an exploded view of each model is included to facilitate procurement of spare parts. . · SECTION II DESCRIPTION 1. The subject models are all of the steerable type, with an automatic full-swivel feature for ease in ground handling. . 2. Figure 1 is an assembly view of the model 3-24B and the model' 3-24BB; those two assemblies are identical except that the model 3-24B has needle swivel bearings while the model 3-24BB has a bronze Bushing for a swivel bearing. The model 3-24BB is recommended for . airplanes having a normal static load of 150 pounds or over on the tall wheel. 3. Figure 2 is an assembly view of the model 3-24BS. This model is identical with the model 3-24BB except that the bracket is de- signed for a tail leaf spring 1 3/4 inclips wide. 4. Figure 6 page 13 shows a typical installation for model 3-24B. or model 3-24BB tail wheel assemblies. SECTION III. INSTALLATION 2002 1. MODEL, 3-24B & 3-24BB. a. Both models are designed for use on specific aircraft having a tail leaf spring 1 1/2 inches wide. bi For installations on a tall leaf spring 1.1/4 inches wide, spring spacer assembly (#1478) is available to take up the clearance between the tail leaf spring and the tail wheel assembly bračket. c. For installations on tail leaf springs with a-3/8 inch dirimeter bolt hole, a bolt hole adapter (#1306) is available. to take up the . clearance between the 7/16 inch diameter bracket, hole and the 3/8 Inch diameter mounting bolt. 07/27/98 MON 10:28 FAX 716 886 1597 SCOTT AVIATION SALES 2003 8. MODEL 3-24BS. 8. This model is designed for use, on specific aircraft having call leaf spring 1 3/4 inches wide with a 1/2 inch diameter bolt hole. 3. GENERAL. An a. The subject assemblies should be fastened to the tail leaf spring with the mounting bolt inserted from bottom to top. 310 nut is recommended and must be cottered securely. b. The spring connector assemblies should be installed, each with a tension of approximately 25 to 30 pounds. This tension can be obtained by stretching each spring approximately one inch on in- stallation'. C. It is recomended that steering leverage be provided on in- stallation to accomplish 45° of tail wheel travel or steering either right or left from neutral position to the extreme stop position of the rudder. d. For those installations utilizing a rudder arm, care mist de taken that the steering horns, or arms are perpendicular to the rudder surface. This is necosmary so that the tall wheel will be in line with the rudder in neutral position, and sp that an equal amount of tail wheel steering performance will be obtained either to right or to loft. 0. For best performance and life of the subject assemblies, the tail wheel spindle bearing should be as nearly perpendicular to the ground line as possible with the airplane at normal static load. condition. 5. ' Installation kits are available for special installations where, the tail le:f spring location and/or angle makes it nécessary. SECTION IV OPERATION 1. The subject tail wheel assemblies provide directional control throughout full ruddor travel of the aircraft while the tail wheel in in contact with the ground. The assemblies will autom tically full-swivel only well after the maximum point of air rudder control is reached in either direction. 2. The tail wheel steering and release mechanism is so designed that 650 of tail wheel turn (or travel) is provided either right or left from neutral steering position before the mechanism begins to release. : SALM OF THEEL ASSY ~00-08-08 CONSIST OF PARTS AS SHOWN ON, EXCEPT THERE WITED ABSPTION.
