Case 651G Wheel Loader Service Parts Catalogue (531647651PC) (September 2025)

A 651G wheel loader usually lives a hard life—quarries, snow work, feed yards, pipe jobs—constantly chewing into piles and shuttling material. This parts catalogue is what you use before you spin a single wrench, so you can plan the job, line up seals, pins, hoses, and hardware, and not have the machine sitting dead while you wait on a $5 o‑ring. Say you’re tracing a hydraulic leak at the boom cylinder: you can match the rod-end gland in the diagram, verify the exact seal kit number, and order everything in one shot instead of guessing.

Applications & Use Cases

• Pre-job planning: trace the system you’re about to open up, then build a parts list so everything’s on the bench when you start.
• During teardown, match what’s in your hand to the exploded view to isolate odd spacers, shims, and bushings that usually get mixed up.
• When parts look almost the same, inspect the callouts and suffixes to avoid ordering the wrong bearing, snap ring, or hose routing bracket.
• Stock your shelf using the initial stocking lists so you typically won’t have to park the loader waiting on common wear parts.
• After a repair, use it to verify you didn’t skip washers, mis-route lines, or mis-align linkages before you button everything up.

FAQ

Q: Is this catalogue searchable, or am I scrolling page by page?

A: It’s generally a digital PDF, so you can search by part number or description, then jump to the right section fast.

Q: Can I print pages and throw them in the service truck?

A: Yeah, most folks print the sections they use most, stick them in plastic sleeves, and keep the original file clean on the shop computer.

Safety Note

Always bleed off hydraulic pressure and chock the machine securely before you start pulling lines or pins you’ve traced in the catalogue.
