| UNIT SUPPLIED. CONDITION OF BEARINGS. Hand brake shaft. Ample lubrication - bearings.good. Clutch and foot brake shaft. Well lubricated. Front brake shaft. Well lubricated - bearings good. Clutch trunnion. Joint well lubricated - no signs of wear. Water pump spindle. Oiled O.K. Bearing surfaces O.K. Gland packing surfaces worn considerably. Rotor XX worn (end thrust). Pendulum lever. Oiled generously - ball pads in excellent condition. Clutch operating shaft. Well lubricated - bearings O.K. Front axle units. Pivots O.S. Plenty of oil - brgs. in good condition. N.S. Oil moderate - bearings O.K. Brake operating shaft - O.S. The bearing was soaked in oil, and oil poured out on removing shaft. Both ends O.K. - N.S. Oil supply scanty and far bearing only just lubricated. We should say that in joints such as this it is advisable to fill the brg. which is fairly oil-retaining when assembling the pieces. Otherwise the 1/8" drip plugs will not meter enough oil to reach the end bearing. Brake toggle shafts - N.S. O.S. Plentiful supply of oil - bearings well lubricated. Cross steering tube. N.S. Ball end and contacts well lubricated. Spring loaded contact badly scored by grit. O.S. Ball end and contacts well lubricated, spring loaded contact scored by grit. Side steering tube. Slight rust - water in joint. Oil present. Contacts and ball good. | ||
