Downgrading of engines in construction machinery, DPF removal
How can we downgrade an engine to a lower Emission status i.e. from TIER V to TIER II ? Can we remove the DPF? Can we disable the Ad-Blue injection system? What happens if we remove the particle filter? Read here more about DPF removal from engines in construction machinery.
How to evaluate swing bearing play of an excavator?
Hydraulic excavators have a slewing ring. This is a large roller bearing with teeth attached to it. The upper carriage of the excavator can rotate endlessly on this bearing. This rotation is caused by a slewing gear. The slewing ring of the excavator is subject to normal wear and tear. Depending on how the machine is treated and maintained, the service life of a slewing ring is between 8,000 and 20,000 operating hours. The wear on a slewing ring can be measured to determine its condition. This measurement can be used to establish whether the values are still within the tolerance range or if the slewing ring will soon need replacing. This repair is extensive and expensive.
