You check this by using a dial indicator on the face of the cam, and the tool capturing the lobe in the center of the bore. Zero the indicator, remove the tool, and push the cam back against the thrust face. The reading is the set-back of the lobe for that cylinder. You can check and record each if needed.

Or lap the thrust face of the cam gear, but that's already been suggested. If you decide to change the dimensions of anything, first use a straightedge to check the alignment of the cam gear to the crank gear.Then see if moving the gear forward (using shim stock) or moving it rearward (lapping the cam gear thrust face or lapping the retainer plate) brings the alignment …

Checking Bearing Alignment Written by MT Staff Monday, 31 January 2000 08:15 Premature bearing failure is often caused by misalignment. Here is how to check bearing position. n anti-friction bearing is considered aligned when the faces of the outer race and inner race are parallel (Fig. 1). Alternately, the races of aligned bearings are coaxial.

Misalignment in bearings occurs when the shaft and bearing centerlines are not properly aligned, causing angular, parallel, or combined deviations. This misalignment disrupts the optimal functioning of bearings, leading to increased friction, wear, and potential failure. Addressing misalignment aims to ensure smooth operation, reduce maintenance costs, and …

4. A "full thrust kiln" is simply one fitted with static thrust rollers that are large enough to fully support the kiln with the carrying rollers neutral. Sometimes with larger and longer kilns there are thrust roller assemblies on two or even more piers. There are kilns that have been built with as many as twelve (12) sets of support rollers.
