CptCurl,

It appears your Lucas product has good Timken O.K. load numbers as well as good 4-ball test numbers. I think you will be fine with it.

Clean throughly and lightly re-lube often. Even light oils will carry abrasives where they are not wanted........ So clean and lube everytime the barrels are off or everytime the double sees dusty conditions is my opinion. With the small amount of grease (or elbow grease) needed it is cheap insurance over the long haul and can be done anywhere.

Best, BigRx
