What type of lubricant do you used and put into those piviot points with the snap caps? On ours all those point has no residued of any kind of lubricant. Grease or gear oil?
Those little flip-top cans are called oilers because you put oil in them. Some folks use chain saw oil because it lasts longer than motor oil. The ones that have screw-on caps are called grease cups, and they take grease. On some old cars the oilers and grease cups need to have the old oil/dirt or grease/dirt cleaned out of them before they're usable. Some of the parts dealers sell a handy lubrication chart that shows all the lube points. It costs about $6.
I use the 600w oil sold for rear ends in the flip top oilers and have done it for many years. For what it is worth it clings like nothing else I have found but still will find its way into every area. Your mileage may vary.
This might help until you can buy a fancy one.
I use 140 gear oil. Same reasons that Paul uses the 600W. The 140 is a lot easier to find and I think works just as good for this purpose.
Notice that the chart that Ken posted has no lube for the rear outer wheel bearings.
I think Henry's book also called for oil on the brake rod hangers in back- every 200, I thnk?
I have to use the gallons of gas for lub. 5 gallons equall 100 mi. If something needs a change or add every 600 mi like the differental thats 30 gallons of gas.
