Caterpillar 630-0153 is the 24 volt electric linear actuator: the black motor and gearbox housing, the aluminium tube with the extending rod and rod end, and the cable with its sealed plug. It is used on Caterpillar 950M to 972XE wheel loaders. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.
The same part is also sold as Caterpillar 581-2664.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Function stops working
When the actuator motor or gearbox fails, the function it drives stops moving or moves only part of its stroke.
Slow or jerky travel
Worn gears and a tired motor make the rod move slowly or in steps, and the machine may log a position fault.
Water in the motor
A cracked housing or damaged cable lets water into the motor and it seizes. Replace the actuator rather than drying it out.
Fitting tips
Disconnect the battery, note the rod position, fit the new actuator with new pins and clips, then cycle it through its full stroke before work.
