Muir Cheetah HR2500 Horizontal Windlass — Owner's Manual

Mounting

  • Centre the windlass fore and aft with a clear lead to the bow roller. Chain leads onto the top of the starboard gypsy, wraps about 100° and drops through the chain pipe.
  • The gypsy centre line must be in the same plane as the chain lead. On a cambered or angled deck, fit a shaped mounting block.
  • Mark from the template and drill 11 mm (7/16") holes for the 10 mm (3/8") deck bolts; mark the chain pipe at the same time.
  • Bed base and block in sealant. On aluminium or steel hulls insulate with a non-conductive gasket, including bolts, nuts and washers below.
  • Light or foam-sandwich decks: fit a plywood stiffener of at least 16 mm (5/8") with large washers.
  • Grease all moving parts on assembly with a lithium / Teflon based grease.

Chain Pipe & Locker

  • Align the stripper with the gypsy centre, wrap the chain through the pipe to position it, then drill and cut.
  • With the optional Rope/Chain Management System, the peeler sits under the gypsy centre and the spring finger on top; check the stripper clears the turning gypsy.
  • Minimum fall to the top of the stowed rode for HR 2500: 650 mm. Aim the chain at the centre of the locker.
  • If the chain falls in a bad spot, a redirect tube at least 1 ½ times the chain width, as near vertical as possible, can move it.

Deck Template

The deck template (second download) is drawn at 1:1 on two A3 sheets: join them at the "Align sheets here" arrows, with BOW pointing forward. It shows the stud holes and the cut-outs for wiring and for hydraulic lines. The current revision adds the extra pair of holes needed only with the composite housing. Print at 100% and check the printed dimensions before drilling.

Electrical

Battery to motor Cable size AWG Cable diameter
7 m (23') 25 mm² 3 8 mm (5/16")
9 – 17 m (30' – 55') 50 mm² 1/0 10 mm (3/8")
  • Motor in this manual: HR 2500, 1200 W, 3 pole.
  • A circuit breaker must be fitted to keep the warranty. It protects wiring and motor; do not use it as an isolator.
  • Fit a separate isolating switch close to the battery or switches.
  • Mount the solenoid upright, out of sea water and close to the motor.
  • Deck switches to port, starboard or behind the windlass, where you can see the anchor coming aboard.
  • Battery as close to the windlass as possible: undersized cable drops voltage and heats up.

Anchoring

  • Free-fall: handle on the clutch nut, turn anticlockwise to release; tighten clockwise to brake the chain.
  • Retrieving: tighten the clutch fully clockwise, remove the handle, then power up. If the anchor is buried, motor forward to break it out.
  • At anchor, take the load on a chain stopper, bridle or snubber. Never use the windlass as a bollard.
  • Mark the chain at 2 and 5 metres (6.5' and 16.5') from the anchor and ease the last two metres in.
  • Never run the windlass stalled or overloaded.

Capstan, MORS & RCMS

  • Capstan: secure the rode (chain lock, gypsy lock or snubber), release the clutch, and the capstan turns on its own.
  • Manual override: engage the locking pawl in the gypsy, ease the clutch anticlockwise, then work the handle; the MOR pawl drives the gypsy and the locking pawl holds the load.
  • Rope finger tension: check at least yearly. Loosen the grub screw on the chain pipe, turn the pin clockwise with a screwdriver to tension, and re-tighten the grub screw.

Servicing

Routine

  • The geardrive is factory-filled and sealed with long-life synthetic oil: no oil changes.
  • Rinse with fresh water after every trip.
  • Clean the clutch cones regularly and re-coat with a thin film of waterproof grease.
  • Strip and grease yearly on pleasure boats, more often on work and charter boats. Use marine lithium or Teflon grease; never soap-based grease.
  • Line: Muir runs 3-strand nylon treated with fabric softener; soak it in fresh water with fabric softener every 3 months.

Strip-Down

  • Tools: clutch / manual recovery handle, 14 mm (9/16") socket with 3" extension, lithium / Teflon marine grease.
  • Remove the hex screw, then the clutch nut (anticlockwise). Slide off the D-cone and gypsy.
  • Grease the exposed main shaft and cone, or continue: remove the capstan screw and capstan, keeping the drive key.
  • Slide the shaft part out and grease the bush bore and shaft.
  • Grease the shaft / cone and gypsy bore, then reassemble in reverse.

Rope-to-chain splice: seize the rope 400 mm (16") from the end, pass the strands through 20 mm (3/4") of heat-shrink and the last link, shrink it, then back-splice with tapered tucks.

Troubleshooting

Area Check
Electrical Breaker and isolator on; battery charged to 12 or 24 V; foot switch plunger contacting; solenoid clicking (low voltage, faulty solenoid or loose wire); wiring intact; then motor brushes.
Mechanical Clutch tightened to the gypsy with the handle; if line slips, increase finger spring tension.
Rope jam Slacken the clutch to free the line. Do not keep running with the anchor or chain jammed: line slipping in the gypsy damages it.
Hydraulic motor Refer to a Muir service agent.
