We’re back with another handy resource detailing the proper lubrication procedures for 5 areas of a CM Lodestar. Maintaining hoists will greatly improve the operation and longevity of your equipment—make sure you’re taking the steps necessary to get the most out of your hoists. This is a quick reference guide, but if you need more information or assistance, we’re only a phone call away. Enjoy!
GEARBOX
The Gearbox is packed at assembly with grease and should not need to be renewed, UNLESS the gears have been removed and degreased.
DIRECTIONS
- Remove gears from housing
- Wipe excess grease off with a soft cloth, and degrease gears and housings
- Add grease to gear teeth and housing using the following chart:
| MODEL | AMOUNT | TYPE | PART NO. |
|---|---|---|---|
| A-H | 7 fl. oz. | Grease (Special) | 28605 |
| J-RR | 15 fl. oz. | Grease (Special) | 28617 |
| RRS | 22 fl. oz. | Grease (Special) | (1) each of 28605 and 28617 |
*DO NOT overfill. This will cause seepage.
LIMIT SWITCH SHAFT
The limit switch shaft must be lubricated properly, but the limit switch gears are made of molded nylon and DO NOT require lubrication
DIRECTIONS
- Apply a light coating of machine oil to the limit switch shaft threads AT LEAST ONCE A YEAR
| TYPE |
|---|
| “3-in-1” or Light Machine Oil |
*CM does not directly stock specific packaged quantities of this oil. When ordering, specify the type of lubricant required and the package quantity you require. Oil can also be obtained locally.
LOAD CHAIN
The lifespan of load chain is greatly increased with proper lubrication. A squeaking sound originating at the liftwheel or sheave wheel areas is an indication of dry chain.
DIRECTIONS
- Keep load chain clean
- Lubricate at regular intervals with Lubriplate Bar and Chain Oil 10-R
- There are several methods to lubricating chain. CM recommends soaking chain, and then hanging chain overnight once saturated. We use a small oil can to run a line of oil as the chain is moving during the process of setting limits to avoid over-saturation
- Use a clean, dry rag to remove excessive oil that remains. This should leave a film protecting the outer surfaces against the elements, but maintaining a sufficient amount to protect the inter-link area
| TYPE | PART NO. |
|---|---|
| Lubriplate Bar and Chain Oil 10-R | 28608 (1 Pint) |
| 28619 (1 Gallon) |
*Normal conditions require weekly lubrication and cleaning. In extreme conditions, clean chain once a day and lubricate several times between cleanings.
LOWER HOOK THRUST BEARING
All bearings and bushings are pre-lubricated and require no lubrication EXCEPT the lower hook thrust bearing.
DIRECTIONS
- Lubricate lower hook thrust bearing
- Ensure bearing is free to rotate and that the oil has successfully penetrated the bearing
| TYPE |
|---|
| Heavy Machine Oil |
*CM does not directly stock specific packaged quantities of this oil. When ordering, specify the type of lubricant required and the package quantity you require. Oil can also be obtained locally.
CHAIN GUIDES, LIFTWHEEL, LOWER SHEAVE WHEEL
When the CM Lodestar is disassembled for inspection/repair, the chain guides, lower sheave wheel (double-chained units), and liftwheel MUST be lubricated.
DIRECTIONS
- Disassemble hoist for inspection/repair
- Apply Lubriplate Bar and Chain Oil 10-R in sufficient quantity to obtain natural runoff and full coverage of chain guide, liftwheel, and lower sheave wheel
| TYPE | PART NO. |
|---|---|
| Lubriplate Bar and Chain Oil 10-R | 28608 (1 Pint) |
| 28619 (1 Gallon) |
