RAMSEY WINCH MODEL HDG-350 PLEASE READ THIS MANUAL CAREFULLY. This manual contains useful ideas in obtaining the most efficient operation from your Ramsey Winch, and safety procedures one needs to know before operating a Ramsey Winch. WARRANTY INFORMATION Ramsey Winches are designed and built to exacting specifications. Great care and skill go into every winch we make. If the need should arise, warranty procedure is outlined on the back of your self-addressed postage paid warranty card.
TECHNIQUES OF OPERATION The best way to get acquainted with how your winch operates is to make test runs before you actually use it. Plan your test in advance. Remember, you hear your winch, as well as see it operate. Get to recognize the sounds of a light steady pull, a heavy pull, and sounds caused by load jerking or shifting. Gain confidence in operating your winch and its use will become second nature with you.
WINCH MAINTENANCE Adhering to the following maintenance schedule will keep your winch in top condition and performing as it should with a minimum of repair. A. WEEKLY 1. Check the oil level and maintain it to the oil level plug. If oil is leaking out, determine location and repair. 2. Check the pressure relief plug in top of the gear housing. Be sure that it is in good operating condition so that hot oil gasses may escape. 3. Lubricate cable with light oil. B. MONTHLY 1.
HYDRAULIC SYSTEMS Refer to performance charts, below, to properly match your hydraulic system to the HDG350 winch performance. The charts consist of: 1. Line pull (lbs.) first layer vs. working pressure (P.S.I.). STATIC refers to lifting a suspended load from rest; DYNAMIC refers to maintaining the motion of a moving load. 2. Line speed, first layer (F.P.M.) vs. gallons per minute (G.P.M.). Performance based on a motor displacement of 3.6 cubic inches with 15 GPM maximum flow rate.
TROUBLE SHOOTING GUIDE CONDITION POSSIBLE CAUSE Clutch inoperaƟve or binds up. CORRECTION 1. Dry or rusted shaŌ. 2. Bent yoke or linkage. 3. Clutch jaws are in contact. Oil leaks from housing 1. Seal damaged or worn. 2. Too much oil. 3. Damaged gasket. 1. Clean and lubricate. 2. Replace yoke or shaŌ assembly. 3. See Techniques of OperaƟon 1. Replace seal. 2. Drain excess oil. Refer to Techniques of OperaƟon. 3. Replace gasket. Winch runs too slow 1. Hydraulic motor worn out. 2. Low Ňow rate. 1.
2. 3. Slide clutch housing #7 from end of drum shaft. Remove setscrew #28, spring #45, and poppet ball #18 from jaw clutch #2. Slide jaw clutch from end of drum shaft. Remove two keys #35 from keyways. A screwdriver can be used, at notch, to aid in the removal of keys. Once keys have been removed, drum #5 and thrust washer # 48 can be removed from drum shaft. Remove motor and coupling #3 from #1 adapter by unscrewing two #27 capscrews with lockwasher. Remove keys #11 from worm shaft.
6. Check for signs of wear on gear teeth. If replacement of gear is necessary, replace as follows: a) Press gear #6 from shaft #14. b) Examine shaft keys and keyways. If distortion of keys and/or keyways is evident, shaft and keys should be replaced. c) Use a soft hammer to gently tap keys #36 into keyways. Press gear #6 over shaft and keys. Gear must be centered over keys. 7. Remove seal #44 from back of #8 gear housing. Press bushing #21 from gear housing. Press new bushing and seal back into place.
RE-ASSEMBLY 11. Apply grease to end of shaft, opposite gear. Apply grease to bushing in gear housing #8. Place greased end of shaft through thrust washer #48 and bushing in gear housing #8. Place gasket #34 onto gear housing cover #4. Apply grease to gear end of shaft and cover bushing. Place cover onto shaft and secure to housing with ten #23 capscrews. Tighten capscrews to 8 ft. lbs. (10.8 Nm) each. 12. Press bearing #19 onto worm #16.
15. Slide spacer #48 over end of drum shaft. Press drum downward to compress drag brake springs in gear housing. Insert keys #35 into keyways with sharp edge of keys pointing outward and notched end of keys upward. A rubber or brass mallet will be needed to gently tap keys into position. Apply grease to keys and end of shaft. Place jaw clutch #2 over end of shaft and slide jaw clutch over keys. NOTE: Be sure that tapped hole on side of jaw clutch is on same side of shaft as the ball detents.
ADJUSTING THE OIL COOLED WORM BRAKE The oil-cooled, fully adjustable, automatic brake operates in the worm housing lubricant, all parts being submerged in oil. When the brake wears to the point that the load begins to drift, the brake can be adjusted as follows: 1. Loosen the lock nut on the adjusting screw. 2. Tighten the brake by turning the adjusting screw clockwise. CAUTION: Only ¼ turn is usually required to adjust the brake. Over-tightening can cause overheating, and damage to the brake parts.
SERVICING OF THE OIL COOLED BRAKE 1. Back off the lock nut, then the adjusting screw, both two turns or more by turning them counter-clockwise. 2. Remove the cover mounting screws. 3. Remove the cover along with coil spring and leaf spring. 4. Remove the retainer plate, composition brake disc, cam plate and balls. 5. Inspect parts as follows: a. Composition brake discs are 1/8” thick when new. Replace if thinner than 0.080” or if surfaces are glazed or burnt. b.
RE-ASSEMBLING AND CHECKING THE BRAKE 1. Press brake hub into place over worm shaft and key. 2. Assemble balls into #1 slots of cam. Use stiff grease to hold balls into place and slide cam over end of worm. Be sure that balls are secure, between cam slots and hub slots. 3. Install brake disc. 4. Install retainer plate, smooth side toward brake disc. 5 Install the gasket on the cover with a small amount of grease or sealer 6. The coil spring goes over the adjusting screw on the inside of the cover.
