None, they represent the same unit. Original King Radio part numbers were 9 digits. For example, 066-3056-01. During the Bendix and King merger (i.e. Bendix/King), a new part numbering system was created that converted these 9 digit part numbers to 12 digits. Therefore, 066-3056-01 became 066-03056-0001. Despite this numbering change, units that were originally from the King Radio design still have the 9 digit part number format on the unit dataplate. The 12 digit format for King units appears to be used for catalog and internal Honeywell purposes only. Therefore, any unit that has a zero in its third to last number (i.e. XXX-XXXX-X0XX) has a 9 digit part number (i.e. XXX-XXXX-XXX) on its dataplate / ID Plate.
For the most part, the system wiring and connections are the same. The only wiring change needed pertains to the HSI unit. The KI-525 contained a Power flag instead of the standard Heading (HDG) flag as with the KI-525A. Therefore, pin P must be added to the existing KI-525 harness for the HDG flag in the KI-525A.

If the HSI is being upgraded to the -07 version of the KI-525A, then there is another pin that must be jumpered. Please see the KI-525A FAQ for more information on this matter.

The original KCS-55 system contained the KA-51A slaving accessory. This still can be utilized in the KCS-55A however it is recommended to upgrade to the KA-51B due to the age and lack of availability of service parts for the KA-51A. If the KA-51B is added, then a connector change would be required.

Mod 1 for the KG-102A gyro capsule (P/N 060-0016-00) incorporates mechanical locking devices on the spin motor assembly and bearing end play adjustments. Quite simply, this modification should be incorporated when the gyro requires maintenance since service parts for gyros not containing this mod are no longer available.

The modification itself consists of installing a redesigned outer gimbals assembly and housing cap with a new bearing retainer and lock nut. The old style had glued in bearings.

The parts kit for installing this Mod is not cost prohibitive. However, due to the labor required to install the kit, the parts and labor cost exceed the gyro value in most cases.

Gyro capsules with serial numbers above 21390, KG-102A assemblies S/N 17698+, and KSG-105 assemblies S/N 3642+ should have had Mod 1 incorporated during original manufacturing. On such units, please note that Mod 1 is not marked on the dataplate(s).

In any case, to determine if a KG-102A gyro capsule has Mod 1 incorporated, inspect the gyro can mod chart either on top of the can (if available) or the gyro capsule dataplate underneath the can (3 screws must be removed). Please reference these pictures.

The maximum drift rate for the KG-102A and KSG-105 directional gyro is 1 degree per minute.
In January 1989 Bendix/King changed from a nine digit to a twelve digit part numbering system. The new, larger 12 digit numbers allowed for the inclusion of software version into the last two digits of the part number for certain units in which software changed frequently such as EFIS and TCAS processors. Therefore, the two digits immediately preceding the software version indicate the hardware version of the unit.

Different software versions imply different operational features and/or interface capabilities and software modifications imply software repairs (bug fixes) to insure proper operation of these features and interfaces. Software version upgrades frequently require hardware modifications to the unit. Such hardware modifications accompanying software version upgrades do not necessarily change the hardware version of the unit.

The Century NSD-360A is vacuum driven while the KCS-55A is electrically driven.

Southeast Aerospace exchanges are based on the return of an undamaged, economically repairable core unit with identical part number as the unit shipped to the customer. An "economically repairable" core is defined as one where the cost to repair/overhaul (or Repair Cap) does not exceed 80% of the original SV/OH exchange price billed. Should the Repair Cap exceed 80%, the customer will be billed the additional amount. In the event this amount exceeds the Outright Price for the unit, the customer would only be billed the difference between the Outright Price and SV/OH Exchange Price with the core returned as-is to the customer.

Here is an example of such a transaction:

$1000 Exchange Price charged to customer
$1000 x .8 = $800 Maximum Allowable core repair charge or Repair Cap

$2000 Cost to repair core unit
- $800 Less Core repair cap
---------
$1200 Additional billing amount.

2200.00 Total Cost of transaction

Please Note:
SEA offers exchange on new items as well. However, repair cap as indicated above is still based on SV/OH exchange price.
It is possible to purchase the shock mounts separately. However, due to the high cost of the shock mounts, it is more economical to purchase the complete KG-102A installation kit (P/N 050-01410-0002).

Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 80% of the original exchange price. That is, it cannot cost SEA more than 80% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.

The KG-102A can supply 400 Hz power and eliminate the need for an additional inverter. Pins little p and t on the KG-102A provide the output. Please note that the KG-102A has a 5 VA maximum of 26VAC 400Hz power available. If more than 5VA is required, then an external inverter would be necessary.
KG-102A gyros above serial number 34591 have Mod 6 incorporated during original manufacturing. Mod or SB 6 improves power supply board reliability for the KG-102A unit. Some original KG-102A units have experienced complete power failures as a result of the original board used in production. The updated power supply board related to SB 6 provides a more reliable, robust power supply board for the unit.
