LFIC (Removable Core) Cylinders
Installation Notes
The 6300 series LFIC (Removable Core) uses a control key whose bittings match
the Top Master Key of the key system in positions 1, 2, 5 and 6. The control
bittings in positions 3 and 4 are selected from the Key Bitting Array of the
master key system.
This method signifi cantly reduces the bittings available in the Key Bitting
Array of any Top Master Key. Increasing the levels in the master keying system
and cross keying also has a signifi cant impact on the yield of keys at each
selected level.
The chamber stack value for the 6300 series LFIC (removable core) is normally
calculated by using a stack value of 15 in positions 1, 2, 5, and 6. This is
the total value of the bottom pins, master splits and driver pins that would
be required to pin the core (based on the keying levels).
In chambers 3 and 4 of the 6300 series LFIC (removable core), the stack value
is 20. This is done to allow the control key to achieve a shear line in
chambers 3 and 4 of the control sleeve.
Important: Cylinders master keyed at the factory use hollow drivers and
SARGENT recommends their continued use. Hollow drivers must be used in
chambers 3 and 4. A different spring is used in conjunction with the hollow
drivers.
These special drivers and springs are included in a special pinning kit 437
RC. The drivers and springs can also be ordered individually. The machined or
hollow end of the hollow driver faces towards thespring.
- 65-6300 or 1 bitted cylinders are supplied for fi eld keying and are provided with 2 key blanks
- 65-6300 cylinders are shipped without pins and springs
- 1 bitted cylinders supplied for fi eld keying have pins loaded only in chambers 3 and 4
- 111111 bitted cylinders utilize a control key cut 113511
Installation Instructions
A Remove the retaining ring, then remove the barrel from the cylinder body and
sleeve or load from the top using the Top Loading Kit (P/N 436-1).
b With sleeve positioned correctly in cylinder body (as shown above), load
barrel and cylinder body. Use the template on page 4 to determine pinning.
Note: The SARGENT rekeying kit 437 RC contains the hollow drivers and
springs that must be used in chambers 3 and 4 for factory keyed cores prior to
January 2009.
c Finish assembling by installing the retaining ring to barrel. The barrel is designed to hold the ring in position.
Important: The retaining ring must clear keyway.
Template
The following is an example showing how to select the pin segments for each chamber of the SARGENT 6300 series LFIC (removable core). Use this as a template for calculating the correct pin loads.
List of Operating Keys
| List of Operating Keys | Sample KEY SYMBOLS |
|---|---|
| List Day Changes/MK’s GM’s etc | GM “A” |
| Do Not list bitting of | MK “AA” |
| the Control key in this area. | CK “AA1” |
2 Calculate Bottom Pins and Master Splits
Find correct size for Bottom and Master Splits from operating key’s list
(a) BOTTOM PINS
(Smallest number in each chamber)
(b) MASTER SPLITS *
(Difference in smallest and largest number in each chamber)
3 Calculate Value of Control Splits
3.3 CONTROL KEY BITTING
(3.1) A number 8 appears on this line in positions 3 and 4
(3.2) Insert bitting of positions 3 and 4 of control key.
and add to number 8’s in positions 3 and 4
3.3 CONTROL PIN FACTOR
(3.4) Subtract largest number in positions 3 and 4 from list of operating keys
from control pin factor
(c) CONTROL SPLITS 
4 Calculate Top or Driver Pin
(Total Stack Value)
(4.1) Add value of: (a) Bottom Pins, + (b) Master Splits + (c) Control
Splits).Enter total here.
(4.2) Subtract total from TOTAL STACK VALUE above.
(d) (4.3) Enter values on this line. DRIVER SPLITS (Master Splits)
