During manual repack, you may encounter common issues that can affect the instrument's performance. Here are some solutions to common problems:
A Complete Guide to Repacking a Hilger & Watts Theodolite for Safe Transport and Storage
For detailed diagrams of specific components like the micrometer drums or the MK II elevation circle drive, you can refer to the Hilger & Watts Microptic Manual .
For cleaning out blind screw holes and delicate internal threads without leaving fibers behind. Consumables
A dedicated lens cleaner or a 50/50 mix of reagent-grade isopropyl alcohol and distilled water. 2. Documenting and Witness Marking hilger watts theodolite manual repack
Position the telescope so it points directly down through the standards, or lock it horizontally if your specific case features a fitted wooden yoke for the telescope barrel.
Multi-compartment pillboxes or ice cube trays to organize parts sequentially by disassembly step. Solvents and Lubricants
The main vertical axis (the center) must spin with zero wobble and perfect uniformity.
Repack the threads with a thin film of medium grease and re-thread them evenly back into the lower tribrach casting. 3. Disassembling and Repacking the Horizontal Axis During manual repack, you may encounter common issues

Clean the fine-thread tangent screws thoroughly until no grey or black residue remains in the threads.
By taking the time to properly maintain and calibrate your Hilger Watts theodolite, you can ensure that it continues to provide accurate and reliable results, helping you to achieve your goals in surveying, engineering, or geology.

: Allow all parts to air dry completely or use low-pressure compressed air. 3. Lubrication and Reassembly
Anti-seize compound/medium grease for the exposed foot-screws on the leveling head.
