QCC took over the manufacture of the Webster & CP pumps and motors product families using the original tooling, assembly and test procedures transferred to us from Danfoss the Original Equipment Manufacturer (OEM). These products are exact matches to the original equipment part numbers and have been in production for many years with QCC.

For more than 60 years, Webster has been synonymous with superior quality, high performance gear pumps and motors. QCC has been manufacturing the Webster B, YB and YC product lines since 2004. In 2010, QCC extended its gear pump and motor offering with the transfer of the CP product line from Danfoss to QCC. The Webster/QCC line of gear products ranges from 0.06 cubic inches per revolution to 9.89 cubic inches per revolution (1.80 to 162 cubic centimeters) with mounting flanges 4F17, SAE A, SAE B and SAE C mounts. Options include flow divider models and multi-section pumps. K Series hydraulic pumps and motors provide the ultimate in flexibility, with numerous displacements, features, and shaft/port options.

QCC now manufactures K Series (formerly Danfoss) Pumps and Motors which have an excellent reputation for rugged, dependable performance at continuous pressures to 3000 psi (207 bar) and speeds to 3000 rpm. Applications include in construction, agriculture, lawn/turf care, cement mixers, fan drives, power steering and more. We also have also resurrected many of the formerly “obsolete” models to support our customers’ needs including PTO hydraulic power supply systems for agricultural applications.

I have a 1960 M5 with weak hydraulics. Everything works Ok when cold, but after its warmed up (10 min) the hydraulics get very very weak. After changing the fluid and filter I now would like to rebuild the pump.

It is MM part no. 10A17561, Webster no. 3JDS4-1RT (98075 M71). I am hoping that just the "wear plates" need replacing and that there is not much other mechanical wear.

My repair catalog lists 6 different Webster pumps used on M5s and M504s. My pump is one of two that have "E" shaped rubber seals, "E" shaped wear plate seals(ivory), and an oval rubber wear plate seals, and oval shapped wear plates, all sandwiched together. There are 29 parts in total, 15 G.P.M.

My hydraulic preassure should be up around 1250psi. When cold it is about 700psi, after 15 minutes of warm up it drops very very low. The configuration of wear plates with 3 seals sandwiched on each side would provide alot of possibilities for leakage. And the varied pressure with fluid temp seems to indicate the pump needs rebuilding. All hydraulics get weak at the same, 3pt, remotes, and power stearing.

I could also use MM pump 10A11291 (webster 4XCS2-2R), it has the same base plate, and only 24 parts. No rubber and ivory seals, just two pump body shaped wear plates.
