About 700429100000 - O-Ring
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
The catalog describes 700429100000 as a coolant-pump O-ring with marking A 100 X 5. It lists 614D15702/1, 11.32287-2006, and 700294100000 as earlier references. Confirm the dimensional convention, seal material, and pump position rather than assuming all rings of that size are equivalent.
Technical Notes: Gaskets and seals
Gaskets, O-rings, and sealing rings keep oil, coolant, fuel, charge air, and exhaust gas in their own circuits. On high-speed MTU engines they work against high combustion pressures and frequent thermal cycling, so a seal that looks intact can still have lost its elasticity or set to the shape of the old joint.
When This Type of Part Is Usually Replaced
- a joint has been opened for inspection or repair, even if the old seal looks usable
- oil or coolant weeping appears at a cover, pipe flange, or housing
- a coolant test shows oil contamination or combustion gas in the cooling system
Checks Before Ordering
- Material matters: fuel-system and coolant-system O-rings of the same size can use different elastomers
- Superseded gasket numbers often reflect a material or thickness change, so mixed old and new gaskets on one joint should be avoided
- Order the complete set for a joint rather than single pieces when the cover or head comes off
Technical Data Status
Published catalog details help identify this part, but they are not a controlled drawing for the item offered. Measurements that are not shown here still need confirmation before substitution or order.
- Confirm inside diameter, cross-section, material, and the exact coolant-pump sealing position.

Engine-series references do not confirm every installation. Final fitment of 700429100000 depends on the full engine serial number and assembly position.
Cross-Reference and Superseded Part Numbers
Catalog history distinguishes earlier and later numbers where documented. Reference-only entries do not establish replacement direction or interchangeability. Confirm the offered number against the engine serial number and installation.
| Part number | Catalog relationship |
|---|---|

Other Parts in the Same Assembly Group
Catalog descriptions for MTU 956 engines list these part numbers under the coolant pump. The grouping follows the catalog text; it is not a confirmed kit list or a drawing revision. Parts in the same group are often renewed together, but each reference still needs its own fitment check against the engine serial number.
| Part number | Description |
|---|---|
| 5802040801 | Spiral Housing |
| 5802040072 | Nut |
| 5802040806 | Impeller |

700429100000 FAQ
Can I replace 700429100000 with any 100 x 5 O-ring?
Matching nominal size is insufficient. Material, fluid compatibility, temperature, and installation requirements must also match.
Is 614D15702/1 replaced by 700429100000?
Catalog history lists 700429100000 as the later number for 614D15702/1, 11.32287-2006, 700294100000. Orders quoting those numbers are normally supplied as 700429100000; we confirm the change against the engine serial number, because a later number can come with related changes to mating parts.
Verification Notes
- Catalog references and engine-series listings require confirmation against the full engine serial number before order.
