About 5849900851 - Nut
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
5849900851 is a nut from the coolant pump group of MTU 956 engines. It is the later number for 5842040050, 5842040072, so lists quoting those numbers are normally supplied as 5849900851. The catalog unit weight is 0.115 kg, which we use to estimate freight before quoting.
Technical Notes: Drive components
Gears, shafts, couplings, belts, fasteners, and locking parts transmit drive to pumps, camshafts, and auxiliaries and hold assemblies together. Many of these items are inexpensive but critical: a missing tab washer or a reused stretch bolt can cause a far larger failure.
When This Type of Part Is Usually Replaced
- locking elements such as tab washers or self-locking nuts have been removed
- gear teeth, splines, or keyways show wear or pitting
- belts show cracks, glazing, or incorrect tension after adjustment
Checks Before Ordering
- Use new fasteners where the maintenance documentation specifies single use
- Order belts as matched sets on multi-belt drives
- Check slotted nuts, washers, and pins together with the component they secure
