GU-4000 Universal Joint 47.62×134.9 mm Loose-Plate Kit

GU-4000 universal joint is a heavy-duty propeller shaft cross kit with 47.62 mm bearing cup diameter and 134.9 mm overall span. It is designed for driveline repair work where a loose retaining-plate installation is required. The complete kit shown includes the universal joint cross, four rounded bearing-cup retaining covers, two long locking plates, eight bolts and a grease fitting. This layout makes the product suitable for selected European commercial-vehicle and truck propeller shaft applications, subject to dimensional and mounting verification.

The size is also commonly written as 47.5×135 mm or 47.6×135 mm in aftermarket listings. For consistent technical identification, MR Driveline uses the catalog dimension 47.62×134.9 mm on this page. Before ordering, compare the bearing cup diameter, overall span, retaining plate shape, hole positions and bolt arrangement with the removed part.

Product Features

Heavy-duty cross and bearing-cup assembly for commercial driveline service.
47.62 mm cup diameter and 134.9 mm overall span.
Loose retaining-cover and locking-plate installation shown in the product image.
Greaseable design with a side-positioned grease fitting for scheduled lubrication.
Complete service kit with four retaining covers, two locking plates and eight bolts.

Cross Reference Numbers

Common catalog searches for the GU-4000 universal joint include GU4000, Hardy Spicer HS316, SKF UJ333, Meritor R279X, Moog 333, Rockwell CP16NS and WHX 5200AGF. Cross references are supplied for product identification only. Different catalogs can group dimensionally related joints even when the retaining system or supplied hardware differs, so the number alone is not a final fitment guarantee.

Some catalogs also associate the dimensional family with 5-279X-style references. However, welded-plate and loose-plate versions may not be directly interchangeable. Confirm the exact cover, locking plate and bolt configuration before using any alternative reference.

Typical Applications

This GU-4000 universal joint is typically searched for selected European truck, commercial vehicle and Leyland-type propeller shaft repairs. Because driveline assemblies can vary by chassis, axle, transmission and previous shaft replacement, application should be confirmed from the old joint or propeller shaft drawing. The most reliable checks are the 47.62 mm cup diameter, 134.9 mm span and the loose-plate retaining arrangement.

FAQ

Is 47.5×135 mm the same size as 47.62×134.9 mm?

47.5×135 mm and 47.6×135 mm are common rounded market descriptions. The more precise catalog size used for this GU-4000 universal joint is 47.62×134.9 mm. Always measure the old part before ordering.

Are GU-4000 and GU4000 the same reference?

Yes. The hyphen is often omitted in search results and catalogs. Both forms normally identify the same GU-4000 product family, but the supplied plate and hardware configuration must still be checked.

Can I order this part only by the HS316 or UJ333 number?

HS316 and SKF UJ333 are useful catalog references for the dimensional family. Please also verify 47.62×134.9 mm and send a photo of the retaining arrangement so MR Driveline can confirm the correct GU-4000 universal joint kit.

Is this automatically interchangeable with every 5-279X listing?

No. Dimensional overlap does not guarantee the same retaining plates or hardware. A loose-plate GU-4000 kit and a welded-plate version can require different yokes or installation parts.
