How to grease a truck. Thrust bearing and cross shaft. This is a grease nipple for our thrust bearing it’s located on the bell housing which is the front of the gearbox. I’ve removed this plate so we can have a closer look. Be careful not to over grease the bearing. Excess grease can find its way to the clutch lining and can make your clutch slip. A couple of pumps is all you need.
Moving on to the cross shaft, grease nipples are located either side of the bell housing. A few pumps of grease and you’ll see it starting to come out of the bush. Moving across to the other side of the bell housing, pretty self-explanatory. While your greasing the cross shaft you should check the clutch free travel. Pull against the spring. There needs to be a small amount of free travel. Without any movement this means the thrust bearing is constantly slightly engaged leading to premature failure.
