COLD WEATHER LUBRICATION
REMINDER! Now is the time to change oil to prevent engine damage from heavy summer oil.
Cold heavy oil will not flow from the oil tank through the oil lines to the oil pump. The bearings, pistons, bushings, etc., will not be lubricated if the oil does not reach the oil pump. The results will be, in most cases, scuffed pistons on the Chief models and burned out connecting rod bearings on the Arrow and Scout models, because these are the first parts to be affected by the lack of lubrication. To prevent this damaging condition, there are three precautions to be taken:
- The proper brand of oil must be used (Indian).
- The oil in the engine and transmission must be changed at this time of the year because of the changes in temperature.
- The engine must be idled long enough to warm up the oil in the tank so that it will flow down the oil lines freely and circulate through the oiling system before starting off.
THE RECOMMENDED GRADES OF OIL FOR MOTORCYCLE USE:
ENGINE: ARROW – VERTICAL SCOUTS – CHIEFS – 45″ SCOUTS – 74l MODELS
| Below 0°F. | Use S.A.E. #10-W |
| Between 0°F. and 32°F. | Use S.A.E. #20-W |
| Between 32°F. and 60°F. | Use S.A.E. #30 |
| Above 60°F. | Use S.A.E. #50 |
Use the same grade of oil in the Arrow and Vertical Scout model transmission as recommended for the engine.
Recommendation for breaking in: Use one grade lighter than indicated by temperature own to #10-W.
PRIMARY DRIVE AND CLUTCH: ARROWS – VERTICAL SCOUTS
| All Temperatures | Use S.A.E. #10-W |
TRANSMISSION – PRIMARY DRIVE – CLUTCH: 74″ CHIEFS – 45″ SCOUTS – 741 MODELS
| Below 0°F. | Use S.A.E. #10-W |
| Between °F. and 32°F. | Use S.A.E. #10-W |
| Above 32°F. | Use S.A.E. #30 |
