Service Manual Information Model and Serial Number Information Most Ritchie comes built after 1974 were supplied with a model & serial number sticker which can be found on the com bowl or the bottom of the housing. The serial number is key to determining what year a com was built, which in turn helps you determine what parts to order in this manual. The serial number will take one of three forms. 1. A code number stamped in the bezel designated the model # and year of manufacture. Ritchie with this number for model and year information. 2. A code that consists of a letter (A, B, C, or D) and a slash /, followed by a 2 digit number. 3. A 10-digit number in which the first 2 numbers represent the year of manufacture and the second two indicate any mid year model changes. These changes are referred to as Rev numbers. (00 indicates no changes) (01 would indicate Rev 1) Note: Some comes have a –R in the serial number. This indicates that a Globemaster has been upgraded to a bladder style diaphragm and bowl. Examples of serial numbers A/87 A/87-R 94.000123 94.010124

Built in 1987; any parts ordered will be for a 1987 model com. Built in 1987 but upgraded to a bladder style diaphragm and bowl, order accordingly. Built in 1994; consider it a 1994 in this manual Built in 1994: consider it a 1994 Rev 1 in this manual.

Zone Sticker & Dial Balance For the ultimate in accuracy Ritchie Com Dials are balanced to accommodate for magnetic inclination in the Northern Hemisphere. By special request Southern Hemisphere dials are available. To determine if a dial has been balanced for Zones 2 through 7 check the bottom of the dial for a scribed number. (Models made after 1997 will also have a zone label on the bowl. Please indicate zone when ordering a dial for the Southern Hemisphere. Note: Dials in the Explorer models will function properly in all zones except 7. Fluid Labels (Isopar L) All Ritchie comes (except sealed capsule models) will have an ID label indicating that the com is filled with Isopar. Older models containing odorless Mineral Spirits will have no ID label. Using This Manual This manual is divided into seven sections arranged by com family. An Index is provided at the back of the manual for model number reference. Most even number pages have diagrams showing com breakdown. Each part is assigned a key number, which is used in conjunction with the parts list found on the next page. If there is more than one key number assigned to part, different colors or types are available. N/A indicates that the part is no longer available. In some cases a replacement part may be available and the part number is given.

Repair Tips Opening comments 1. Be careful not to disturb the compensators when performing a repair. If you do, re-compensation will be necessary. 2. Before beginning any service work, check the dial’s sensitivity. 3. Replace O-rings on all repairs. 4. Make sure you do not disturb the factory bend in the balance tab, unless re-balancing the gimbal ring & pan assembly is necessary. 5. When reassembling fully gimbaled units, make sure to install the gimbal with the correct side up. The flat surface should be on top and the gimbal pins and springs should not be visible. General Repair Tips Sticking dial 1. Before disassembly, follow these steps to test for a sticking dial. a) Allow dial to settle, and then take note of the reading. b) Deflect the dial 5o to port with a ferrous screwdriver or similar device. c) Check to see that the dial returns to the original reading. d) Repeat steps b and c, this time deflect the dial to starboard. 2. If the dial fails to return accurately the cause is usually a worn or defective pivot or jewel. The complete dial assembly must be replaced. The pivot and jewel are not field repairable. 3. Drain the com of fluid and remove the dome. 4. Do not disturb the factory bend in the balance tab, unless the gimbal system is off balance. If it is off balance, refer to the next section. 5. Replace the dial assembly and re-assemble the com with new O-ring seals. Gimbal system off balance 1. Drain the com of fluid and remove the dome. 2. Allow the dial/pan/gimbal assembly to dry thoroughly before attempting to balance them. 3. Check the pan to gimbal ring spacing. The pan should have just enough clearance to swing freely within the ring. Excess spacing will cause the pan to slide side to side and make accurate gimbal balance virtually impossible. 4. Set the bowl on the bench and using a small bubble level shim it until the top is level. 5. Place the dial/pan/gimbal assembly in the bowl and observe the relationship between the gimbal ring and the top of the bowl. If necessary, bend the balance tab to level the gimbal ring with the top of the bowl. 6. Observe the relationship of the pan to the gimbal ring. If necessary, bend the balance tab to level the pan with the gimbal ring. 7. Re-assemble the com with new O-ring seals.

Repair Tips & Fluid Requirements

Bubble in the fluid A bubble in the fluid usually indicates a leak or incomplete vacuuming of the fluid. The problem may be caused by inadequately bottomed bezel or diaphragm retaining screws, improperly installed fill plug screw, failed o-ring, diaphragm, bowl, or crazed dome. 1. Check to see if there is an O-ring or diaphragm leak by pressing on the diaphragm. 2. Replace the failed part. 3. Make sure the diaphragm retainer is completely bottomed out. 4. Re-assemble the com with new O-ring seals. Dome Replacement 1. Always replace the dome if any cracks or de-lamination is visible. 2. When re-assembling a flare type dome, the dome must be centered inside the bezel and the bezel screws must be tightened evenly in a torque pattern. There should be a space left between the bezel and clamping ring that is even all the way around. 3. When re-assembling a compression type dome, the dome and bezel will self-center. the bezel screws must be tightened evenly in a torque pattern. The bezel will bottom against the bowl (or clamping ring) when the screws are tight. Dampening Fluid Always use Ritchie com fluid. (Be sure to subject the fluid to a vacuum equivalent of 28 inches of mercury for a minimum of 15 minutes before sealing it in the com. This step prevents the formation of a bubble in the fluid due to temperature changes.) Ritchie began using Isopar L as dampening fluid during 2001. This fluid is a high-purity isoparaffinic solvent very similar to Odorless Mineral spirits. Ritchie changed to this fluid because it has a higher flash point and conforms to most of the world's shipping regulations. It is important to note that some other manufacturers use Isopar M as their dampening fluid. PLEASE NOTE: ISOPAR M CANNOT BE USED IN RITCHIE COMES. Replacing Odorless Mineral spirits with Isopar L Ritchie will no longer be providing Odorless Mineral Spirits. If you have a com that has odorless mineral spirits, you can replace it with Isopar L. It is recommended that you completely replace the old fluid with Isopar L. There is no harm to the com if a small amount of Odorless Mineral Sprits is mixed with the Isopar L.
