U992 ZK6800 Universal Joint 68x89x165.5 mm for SHACMAN F3000

Description

U992 Universal Joint 68x89x165.5 mm

U992 universal joint is a heavy-duty propeller-shaft cross kit in the distinctive 68x89x165.5 mm dimensional family. The configuration uses 68 mm bearing cups, large 89 mm slotted retaining components and a 165.5 mm overall span. The photographed kit contains one forged cross with four installed bearing cups, four separate black slotted external retaining rings and one 90-degree elbow grease fitting.

U992 and ZK6800 are the strongest catalog search references for this configuration. The product is commonly marketed for SHACMAN or SHAANXI F3000 heavy trucks. Some regional listings shorten the size to 68×165.5 mm or round the span to 68×166 mm; keep the full 68x89x165.5 mm specification as the primary identification.

Product Features

• Large forged cross body engineered for heavy commercial driveline loads.
• Nominal 68 mm bearing cup diameter and 165.5 mm overall span.
• Four polished bearing cups with visible grooves and yellow-green seals.
• Four large external retaining rings with a distinctive elongated slot.
• Greaseable center-port design with a separate 90-degree elbow fitting.
• Search coverage for U992, ZK6800, U462 and the 5-12018X catalog family.

Installation quality directly affects the life of a U992 universal joint. Clean the yoke bores and all cup-retaining surfaces before pressing. Keep each cup square, support the opposite yoke ear and prevent needle rollers from falling beneath a trunnion. Fit every slotted ring completely into its intended position, install the elbow fitting where it clears the yoke and verify free articulation without axial looseness, binding or uneven seal compression.

Cross References and Identification

Verified searches for the U992 universal joint should prioritize ZK6800 and the complete 68x89x165.5 mm size. U462 and 5-12018X appear beside the same 68 mm and 89 mm dimensional group in some catalogs, but their exact span, ring profile and groove position must be confirmed before interchange. Treat these as useful inquiry references rather than unconditional substitutes.

SHACMAN-market listings may also use seller numbers such as 20004740 or 5412733. These can be included in a compatibility inquiry, but dimensions and photographs remain more reliable than a retailer number used outside its original system. The number 1903611080 is intentionally excluded because public catalogs also assign it to a different 57×144 mm joint.

Before approving a replacement of U992 universal joint, compare cup outside diameter, full over-cup span, retaining-ring outside dimension, cup groove position, ring thickness, seal profile, lubrication-port location and yoke condition. A product described only as 68×166 can look similar while using another retention design. Clear images of the removed cross, rings and yoke reduce expensive identification errors.

Photographed Supply Configuration

The photographed U992 universal joint kit is supplied with one cross, four installed polished bearing cups, four visible yellow-green seal rings, four large open slotted retaining rings and one loose 90-degree grease fitting. This exact component count separates it from plate-retained joints, ordinary eyelet-circlip kits and maintenance-free versions without an accessible grease port.

Typical Applications

The U992 universal joint is mainly researched for SHACMAN or SHAANXI F3000 heavy-truck propeller shafts and related commercial driveline repairs. Replacement markets in Central Asia, Russia and parts of Africa commonly identify it by vehicle family plus size. Exact fitment can still change with axle type, shaft manufacturer, chassis configuration and earlier driveline replacement.

For compatibility checking, send MR Driveline the old model number, measured cup diameter, overall span, ring dimension, ring thickness and clear photographs of both yokes. Also state whether the vehicle uses an AC16/MAN-type or STEYR-type axle and whether the shaft is original. This information is more dependable than confirming only the truck badge or production year.

Why Choose MR Driveline

MR Driveline organizes every U992 universal joint inquiry around verified dimensions, retention geometry, application evidence and photographed supply configuration. This avoids merging ordinary 68×165.5 mm joints with the special 68x89x165.5 mm slotted-ring version. We support distributors and repair workshops with sample checking, private-label packaging, batch control and repeat-order identification.

FAQ

Are U992 and ZK6800 the same product?

They are widely paired with the 68x89x165.5 mm configuration. Confirm the ring profile, cup grooves and overall span before approving a substitute from another manufacturer.

Can 68×166 replace 68x89x165.5 mm?

Not automatically. The rounded span is close, but the 89 mm retaining-ring dimension and groove arrangement must also match the original yoke.

Is it suitable for SHACMAN F3000?

It is commonly sold for F3000 driveline service, including heavy 6×4 and 8×4 applications. Confirm axle, shaft and yoke measurements for each vehicle.

What is included in the kit?

This U992 universal joint kit includes one cross with four installed cups and seals, four slotted retaining rings and one separate 90-degree grease fitting.

What measurements are required before ordering?

Measure the 68 mm cup diameter, 165.5 mm overall span, 89 mm retaining dimension, groove position and ring thickness. Confirm clearance for the elbow grease fitting.
