Fixing a vintage Martin Automatic Mohawk fly reel requires patience, a clean workspace, and an understanding of its internal clockwork spring mechanism. Unlike modern disc-drag fly reels, automatic reels rely on a powerful internal mainspring that winds when you pull line out and retrieves it automatically when you press the trigger lever. When these vintage pieces stop retrieving smoothly, jam, or lose tension, diving into the housing can feel intimidating.
This guide walks you through the exact process of safely opening, cleaning, diagnosing, and reassembling your Martin Automatic Mohawk. You'll learn how to handle the mainspring without causing injury, how to clean out decades of hardened grease, and how to tune the trigger mechanism for reliable performance on the water.
Understanding the Mohawk Mechanism
Before you turn a single screw, it helps to understand what makes these reels tick. Martin Automatic reels, including the Mohawk and popular sibling models like the 8A and 49A, use a clock-type mainspring housed within the main drum. When you pull fly line against the tension, you wind this spring tight. Depressing the trigger lever releases a stop-pawl, allowing the spring to spin the spool and take up the slack line.
Over decades of use, factory lubricants oxidize into a sticky varnish. Dirt, sand, and old moisture find their way through the housing slots, binding the gear teeth and dampening the spring. If your reel fails to retrieve, stutters halfway through winding, or makes a grinding noise, the internal gear train needs a thorough overhaul.

Required Tools and Workspace Prep
Working on automatic fly reels requires a controlled environment because tiny components have a habit of disappearing. Clear off a sturdy table and lay down a light-colored silicone mat or an old cotton towel. A light background ensures that loose screws, clips, or tiny springs stand out if they roll away.
Gather the following items before you begin:
- Flathead screwdrivers (various small precision sizes)
- Needle-nose pliers or tweezers
- Cotton swabs (Q-tips)
- A small container or parts tray
- Mineral spirits or a dedicated reel-cleaning solvent
- Lightweight reel oil and synthetic reel grease
- A clean microfiber cloth
Step-by-Step Disassembly
Taking apart a Martin Automatic Mohawk must be done sequentially. Rushing through the teardown can cause the mainspring to uncoil violently or result in lost fasteners.
Removing the Spool and Line Guard
Start by stripping any old fly line off the spool to prevent tangles, or secure the tag end so it doesn't whip around.
- Locate the center drag retaining screw or cap on the front face of the spool.
- Unscrew this center fastener counterclockwise using a properly sized flathead screwdriver or a coin. Keep track of any washers, clicker plates, or tension springs that lift off first.
- Gently pull the spool straight off the center main shaft. Set it aside in your parts tray.
- Inspect the exposed main shaft and the rear frame housing for accumulated grit, old line bits, or corrosion.
Accessing the Mainspring and Gear Train
With the spool removed, you are facing the heart of the automatic mechanism. The mainspring is contained beneath a cover plate secured by small screws.
- Carefully note the position of the internal gears, levers, and any spring retainers before touching them. Taking clear photos with your phone at each step provides a reliable reference during reassembly.
- Remove the small screws holding the inner cover plate or bridge. Loosen them in a diagonal pattern a little bit at a time to relieve internal pressure evenly.
- Lift the cover plate away slowly. If the mainspring is still under tension, hold the gear assembly firmly so it doesn't spin wildly.
- Allow the mainspring to safely unwind completely before removing it from its housing. Never force a spring out while it is tightly wound.
Cleaning and Inspecting Internal Parts
Once the components are laid out, you need to strip away the old, congealed grease that hinders performance.
Soak metal gears, shafts, and plates in mineral spirits or a safe solvent for ten to fifteen minutes to break down old petroleum residue. Use a soft-bristled toothbrush to scrub stubborn grime out of the gear teeth and corners. Wipe down plastic or painted exterior frame pieces with mild dish soap and warm water, avoiding harsh chemical thinners that can degrade vintage finishes or plastic components.
Inspect every part closely under bright light:
- Check the gear teeth for chips, rounding, or excessive wear.
- Examine the trigger mechanism and stop-pawl to ensure the edges are crisp and engage securely with the gear teeth.
- Look closely at the mainspring coils for kinks, rust patches, or stress fractures. A cracked spring cannot be repaired reliably and must be replaced.
Lubrication and Reassembly
Proper lubrication dictates whether your restored Mohawk operates smoothly or catches midway through a retrieve. The golden rule of vintage reel service is moderation: too much grease attracts dirt, while too little causes metal-on-metal friction.
- Apply a thin, uniform film of synthetic reel grease to the main gear teeth, internal sliding surfaces, and the mainspring coils. You can use a cotton swab to spread it evenly without laying it on too thick.
- Place a single drop of lightweight reel oil onto pivot points, bearing surfaces, and the main shaft. Keep oils away from friction brakes or surfaces where slipping is undesirable.
- Reinstall the mainspring into its housing, ensuring the outer hook seats securely into its anchor slot.
- Carefully wind the spring a few turns to preload tension before replacing the inner cover plate. Secure the cover screws snugly, but avoid over-tightening them into vintage threaded holes.
- Slide the spool back onto the main shaft, replace any washers or click plates in their original order, and thread the center cap down until finger-tight.
Testing and Tuning Your Reel
Once reassembled, do not immediately take the reel to the river. Clamp it to an old fly rod or hold it firmly in your hand to test the mechanism through several cycles.
Pull three to four yards of backing off the spool. The line should strip smoothly against light resistance. Press the trigger lever; the spool should spin rapidly and retrieve all the slack line cleanly without stuttering or hesitation.
If the reel hesitates, you likely applied too much heavy grease to the pawl or gear teeth, dampening the spring action. Strip the housing down, wipe away excess lubricant, and reapply a lighter coat. For additional historic context on classic tackle maintenance, review resources provided by organizations like the American Museum of Fly Fishing for preservation standards, or consult manufacturing overviews on Wikipedia's Fly Fishing page to understand how automatic reels fit into angling history.
Common Mistakes to Avoid
Working on vintage gear is rewarding, but small errors can turn a simple tune-up into a frustrating puzzle. Keep these common pitfalls in mind:
- Using WD-40 as a lubricant: WD-40 is a water displacer and solvent, not a long-term lubricant. It strips away remaining protective oils and leaves a gummy residue that ruins smooth operation.
- Over-tightening screws: Vintage metal alloys strip easily. Snug screws down gently rather than cranking them hard.
- Disassembling without photos: Forgetting the exact orientation of pawl springs or levers makes reassembly an exercise in trial and error. Always snap reference photos as you peel back layers.
Frequently Asked Questions
Can I use modern synthetic grease on my vintage Martin Mohawk?
Yes, modern synthetic reel greases and oils work exceptionally well on vintage metal components. They resist temperature changes better than original factory lubricants and do not break down into a sticky varnish as quickly.
What should I do if the mainspring snaps during disassembly?
A snapped mainspring means the reel cannot store retrieval energy. Replacement springs for vintage Martin reels are rarely manufactured new today, so your best option is sourcing a donor reel from an online marketplace or a used tackle dealer to harvest internal parts.
Why does my automatic reel stop retrieving halfway through?
This usually happens because old grease and dirt have packed into the inner coils of the mainspring, or because the gear teeth are fouled. A complete teardown, solvent soak, and fresh re-lubrication almost always resolve this issue.
Is the Martin Mohawk suitable for saltwater fly fishing?
No. Classic Martin automatic reels are constructed from aluminum alloys and steel components that lack modern corrosion-resistant coatings. Exposure to saltwater will quickly cause rust on internal springs and pitting on the frame.
