As an authorised main dealer of Cummins Onan products we are able to supply a wide range of genuine service and general engine parts for all Cummins Onan generators.

Because of the large variety and complexity of parts for this manufacturer it is not always possible to order every single part on-line, however we are extending the range all the time. Please navigate to ‘RV Onan’ or ‘Onan Marine’ to select type of set you required product. If you are unsure, please contact us either by telephone or email and we will give expert advice.

To help us identity the correct part please supply as many details as you have:

Engine Size / type
Engine or Serial Number
Part Number
V-Belts – it is important to know whether the vessel is 12v or 24v and whether it is negative or isolated ground.

NB. Marine Sets – If you own an older set your model may well appear as MDKB’X’ and not MDKDK (for example), the set will be the same, the latter D simply means it meets new emission standards regulatory in the US.
