Our Alaskan Bushwheel 3400 Tailwheel Assemblies are a FAA PMA direct replacement for the Scott 3400 tailwheel assembly.  They come standard black and completely lubed and ready for installation. 

We have all of the internal and individual parts available as well.

P/N: ABI-3400-00  $1475.00

     This assembly comes standard with the 8" fork.

P/N: ABI-3450-00 $1475.00

     This assembly comes standard with the 10" fork. When ordering please determine whether or not you want the ABI-3410-05 (turned up) or the ABI-3410-03 (straight) steering arm.

P/N: ABI-3450-23 $1475.00

     This assembly does not fit the tube spring type tailspring, but instead fits the 2-bolt, flat spring. It does have the option of 8" or 10" fork.

Something New:

The one thing that you will find different about our 3400 tailwheel assemblies is the fact that we have 1 part number for the tailwheel head/mounting bracket instead of 4 different ones like Scott. We have beefed up the tailwheel head for strength and longevity and it comes standard with a 1 1/8" tailwheel spring mounting hole and is the direct replacement for the McCauley/Cessna part number 0742155-7. To accomodate the 1", 15/16" & 7/8" tailspring we have spacers that are inserted inside the standard head.  These spacers are ONLY applicable to our ABI-3412-M tailwheel head and cannot be used with a Scott 3412.

When ordering, please, indicate which size tailspring that you have so that you get the right size for mounting.

ABI-3412-M - Direct replacement for the McCauley/Cessna 0742155-7.

Installation Instructions for the ABI-3400-00/ABI3450-00/ABI-3450-23 Tailwheel Assemblies

This ABI-3400-00/ABI-3450-00/ABI-3450-23 Assemblies are a FAA-PMA direct replacement for the equivalent Scott tailwheel Assembly. The installer is responsible for ensuring that the assembly is installed in accordance with the original equipment installation instructions.

Removal & Installation Instructions of 3400 series tailwheel assembly:
A) Following airframe manufacturers instructions, properly raise and support the tail of the aircraft off of the ground.
B) Disconnect & inspect the steering springs & chains from the tailwheel assembly.
C) Remove the old assembly from the tailspring, inspect the attach bolt and tail spring for correct arch. The center pivot spindle should angle back away from the airplane 5 to 7 degrees when un-loaded and be perpendicular to the ground at maximum gross weight. (Note: ABI recommends replacement of all attachment hardware.)
D) Re-install and adjust in reverse procedure, following the original airframe manufacturers installation instructions. (NOTE: Tension on connector spring is not required or advisable. Over tension will create binding of the steering arm causing it to bend and damage internal parts. Connector springs and connector chain should be just slack. ABI recommends connecting the connector springs to an eye-bolt, not to the rudder arm.
E) All ABI 3400 series assemblies are pre-lubed at the factory with Exxon-Mobile SCH-100 grease. Over greasing of the axle will force the wheel seals (PN: ABI-1863) out against the bearing pre-load spacer (PN: ABI-3227-00) causing premature wear on the seals.

PMA Notice:
The ABI-3400-00/ABI-3450-00/ABI-3450-23 assemblies carry a PMA marking (FAA-PMA # PQ1557NM), which identifies it as having been fully tested, inspected and qualified to meet the FAA specifications and requirements.
After final PMA approval, substitution of critical parts, change of process or materials is not permitted without re-qualification of parts and pieces and resubmitted to the FAA for approval. FAA regulations subject Alaskan Bushwheel Inc., PO Box 2380, 83496 E. Russell LN, Joseph, OR 97846 and the user to constant surveillance that all quality assurance materials and processes contents are maintained in order to provide replacement parts that are the same as the Original Equipment parts in the assembly.
