Introduction
There are reports of damaged connecting rod bearings on 3024 engines that are installed in Skid Steer Loaders and Multi Terrain Loaders.Problem
The connecting rod bearings have been reported as being seized, rotated or loose. The big end bearings on the 3024 engines that are installed in Skid Steer Loaders have been caused by inadequate lubrication. The cause of the inadequate lubrication is a low engine oil level. The oil pump inlet can momentarily suck in air when the machine is on a steep grade with a minimum oil level in a dynamic state.Solution
Illustration 1 g01240993
In order to minimize the potential for this occurrence, the minimum mark (1) on the dipstick should be moved to a point (2) that is 22.5 mm (0.89 inch) higher than the original minimum mark (1). In order to avoid confusion, the dipstick should be cut off at the original minimum mark (1). Ensure that the end of the dipstick (1) is deburred and ensure that the dipstick is cleaned before use. Note: Do not overfill the oil pan as the crankshaft will be immersed in the oil, which will cause aeration of the oil and loss of oil pressure.Note: The modifications to the dipstick have already taken place on all production engines.
