Product Description

D 70629 Universal Joint Assembly is used on the drive shaft between the power shuttle transmission and the transaxle for CASE 580 backhoe loaders.

This universal joint allows the driveline to transmit torque smoothly while compensating for angular movement between the transmission and axle.
It is supplied as an assembly and replaces the original joint set shown in the driveline illustration.

This Precision unit is manufactured to match original fitment and operating angle, helping to maintain smooth power delivery and reduce vibration during machine travel.

Includes

• Universal joint cross

• Bearing cups and related components
  (Includes Ref. 2 – 5 as per parts illustration)

产品说明

D 70629 万向节总成 安装在
动力换挡变速箱（Power Shuttle）与后桥变速箱（Transaxle）之间的传动轴上。

此万向节用于在传递扭矩的同时，补偿传动轴角度变化，使机器在行走时保持平顺、稳定的动力输出，并有效减少震动。

本产品为完整万向节组件，结构尺寸与原厂一致，可直接替换原机零件。

组件包含

• 十字轴

• 轴承杯及相关配件
  （对应图中 Ref. 2 – 5）

零件替代说明

• 已被以下零件号取代：NH80715

• 新 CNH 号码：84512487

（D 70629 可作为上述零件号的替代件，订购前请以机器序列号确认。）

+P 产品特点

• 适用于 CASE 580 系列传动轴

• 用于 Power Shuttle 至 Transaxle 传动系统

• 精密加工十字轴与轴承

• 传动平顺、耐用度高

• 有效降低传动震动与异音

• 可直接安装

故障排查（何时需要更换万向节）

常见现象

• 前进与后退切换时出现“咔嗒”声

• 行走时明显震动

• 传动轴位置出现金属敲击声

• 万向节有明显间隙

• 轴承杯漏油或卡死

可能原因

• 长期缺乏润滑导致轴承磨损

• 进水或灰尘污染

• 长期重载工况

• 传动轴角度不良或安装偏差

安装注意事项

• 同时检查传动轴两端万向节

• 检查叉头是否磨损或变形

• 安装时注意传动轴相位（phasing）

• 安装后务必加注黄油（如有油嘴）
