687.35 Slip Assembly for 42×119.4 mm Universal Joint | 2035 Series

Description

687.35 Slip Assembly Product Overview

The 687.35 slip assembly is a matched sliding-spline component for heavy-duty driveshafts using a 42×119.4 mm universal joint. It combines the yoke-side spline shaft with the mating sleeve so the driveline can change effective length as the suspension and axle move. Bearing bores, fork geometry, spline fit and assembly length are manufactured from the approved drawing.

MR Driveline supplies this 687.35 slip assembly for new shaft production, maintenance programs and drawing-based replacement. The complete matched pair helps reduce the risk of combining spline parts with different tooth forms, fits or working lengths.

Why the Sliding Spline Interface Matters

A driveshaft slip unit must transmit torque while moving axially without binding or excessive clearance. Spline tooth form, major and minor diameters, effective engagement, lubrication arrangement and surface treatment all influence service performance. The 687.35 slip assembly should therefore be selected by drawing and mating dimensions, not by the series reference alone.

Technical Specifications

Fit, Travel and Lubrication Review

Correct travel depends on the shaft’s installed length and suspension movement. Before production, the closed length, normal operating position, maximum extension and minimum spline engagement should be defined. Lubrication method and sealing must also suit the working environment. These checks allow the sliding assembly to move through its required range while maintaining safe spline engagement.

OEM / Equivalent Models

Common identification references include 687.35 and 2035 series. They identify a general component family, but equivalent status must be confirmed by joint size, spline geometry, working length, fork dimensions and lubrication details. A visual match is not sufficient for a torque-transmitting sliding assembly.

What Must Be Verified Before Ordering

• 42×119.4 mm universal-joint size and Ø42 mm bearing bores
• Spline tooth count, tooth form, major diameter and minor diameter
• Closed length, operating length, travel and minimum engagement
• Fork width, bearing-retention details and assembly orientation
• Lubrication, sealing, material, heat treatment and surface protection

Please send a drawing or a measured sample with the required quantity. MR Driveline will use this information to verify the 687.35 slip assembly before confirming production.

Manufacturing and Quality Control

Key controls include bearing-seat position, fork symmetry, spline accuracy, mating fit, sliding movement, concentricity and runout. Depending on the order, material certificates, heat-treatment records and dimensional inspection reports can be discussed. The matched components should be kept together through inspection, packing and final shaft assembly.

Ordering Checklist

For a fast quotation, provide quantity, application, drawing, joint size, spline data, required lengths, operating travel and any inspection requirements. If only a sample is available, mark the normal working position before shipment. This gives the engineering team a clear basis for reviewing the 687.35 slip assembly.

FAQ

Does the series number define the complete spline?

No. Tooth count, form, diameters, fit and engagement still require confirmation.

Is the sleeve included?

Yes. This product is presented as a matched spline shaft and sleeve assembly, subject to the final approved drawing.

Can working length and travel be customized?

Yes. Drawing-based production can be reviewed after the operating lengths, travel and spline-engagement requirements are provided.
