About Us

Ritchmen (S) Pte Ltd is a well-established company in Singapore, supplying Genuine Cummins diesel engine spare parts and Genuine Bosch Fuel Pumps and Injectors around the world since 1976.

Our competitive advantage is our team’s fast response time and specialized knowledge in Cummins Diesel Engine parts and Bosch Fuel Injection parts.

Ritchmen (S) Pte Ltd is helmed by Mr. C.M. Quek, who has been in the Cummins spare parts trade for more than 50 years (and counting!!) and winged by his son, Jesse Guo, who also has been in the trade for more than 20 years. Both of them have extensive hands-on experience and very sound product knowledge to provide sound advice for any Cummins engine parts requirements. From identifying spare parts without part numbers to recommending alternative solutions for obsolete spares, the father and son duo has done it all before.

100% of our inventory are Genuine and sourced directly from Cummins’s Depot and Bosch’s Factory so you won’t have to worry about the authenticity and quality standards of our product! Ritchmen also realizes the cruciality of down time to our customers therefore our warehouse capacity and inventory levels are well-positioned and monitored everyday to tackle long and dreary lead times.

Ritchmen never rests on its laurels and is always on the lookout for strategic partners to collaborate with in order to serve our customers better.

Since 2019, Bosch has appointed Ritchmen as its authorised  parts distributor and dealer for the South-East Asian region.

Our collaboration with Bosch was purposefully tailored to complement and enhance our Cummins engine parts business.

Through years of successful collaboration with Bosch, Ritchmen has built up its inventory of Bosch’s High Pressure CR Fuel pumps and Injectors used across these Cummins Engine Models: QSB7 / QSC8.3 / QSL9 / QSK19 / QST30 / QSK38 / QSK45 / QSK50 and QSK60.
