Fiatallis FD5, FD5LT 1989 Parts Catalog

I’ve been wrenching long enough to know that chasing a part number through aftermarket catalogs is how you end up with the wrong sprocket or a brake piston that doesn’t seat. You order by description, get something that sort-of fits, and waste a day swapping parts that don’t belong. This 1989 Fiatallis FD5, FD5LT 1989 Parts Catalog stops that. It’s the same book the dealer used when these machines were new – 76 pages of OEM part numbers, exploded views, and grid coordinates that tell you exactly which group and section to look in. No guesswork. No “cross-reference” that crosses you up.

Alphabetical Index and Grid System

Every catalog that matters starts the same way: an alphabetical index. Page A-1 lists every assembly from Alternator Mounting to Track Roller Guards. Each entry gives you a Group code (like C101 for Brake Foot Control) and a Grid location (A-16). That grid system is what saves you from flipping through all 76 pages blind. You want the brake foot control – turn to grid A-16. Hand brake control? That’s C135 on grid B-15. The index also includes a Numerical Index starting on page A-2, so if you only have a part number or a previous group reference, you can cross-check quickly. This is not a PDF that dumps you into a random scan. It’s organized shop-floor logic.

What Brake System Parts Are Listed?

Brake assemblies are where I’ve seen the most mix-ups. The FD5 uses a foot-operated brake (C101) and a separate hand brake (C135). The catalog breaks them into separate grids: foot brake on page A-16, hand brake on B-15. Each grid shows the exploded diagram with callouts, then the part number, description, and quantity per machine. If you’re overhauling the final drive or track frame, the brake control linkage is tied into the steering clutch release system (D222). Having the correct part number for the brake pedal shaft, seal, and return spring means you don’t have to wait three days for a mis-shipped item. This catalog gives you that.

7 Major Systems for Undercarriage and Drivetrain

The undercarriage is what makes these crawlers work or stop working. This catalog covers seven heavy sections:

• Track (D340) – chains, pads, pins, bushings
• Track Frame (D330) – main frame with idler mounts
• Track Idler (D334) – including adjustment components
• Track Roller (D337) – single and double flange rollers
• Sprocket (D303, D333) – two variations with separate grids B-2 through B-4
• Track Release Guards (L311) – page E-14
• Track Roller Guards (L311) – same group

Each entry lists the OEM fastener size and grade. Aftermarket catalogs often consolidate these into one part number that doesn’t match the factory spline or bushing ID. You’ll burn out a sprocket fast with the wrong tooth profile. The FD5LT (long-track variant) uses different track frame dimensions – this catalog separates them correctly.

Get the Right Part Numbers for Hydraulics

Hydraulic system parts are scattered across several groups because the FD5 has separate steering, implement, and PTO circuits. For the hand steering hydraulic system (D223(1A)), the catalog shows the pump, control valve, and piping routing. Steering control valve (220(1-3A)) spans grids B-6 through B-10 – includes the relief valve, spool, and spring kits. Hydraulic control valve piping (E302) covers the lines from the pump to the blade and ripper circuits on grids C-10 to C-13. If you’re replacing a leaky hose or a pilot line, the grid reference tells you exactly which diagram to look at. No need to measure an old hose and hope it matches – the part number is there, and it’s the same one Fiatallis stamped in the 1989 bill of materials.

Moldboard and Ripper Assembly: Factory Part References

The moldboard (E313) is a complex assembly with multiple throw-away sections. This catalog splits it into four sub-variants (A, B, C, D) covering pages C-16, C-17, D-15, D-16, and D-17. If you’re running an FD5 with the heavy-duty ripper, the ripper mounting frame (E305) lives on grid C-14. The part numbers for shanks, pins, and the tip are listed with quantities – no guessing whether you need four or six bolts per pocket. I’ve seen jobs where a tech ordered the wrong blade end because the aftermarket book listed one part for all moldboards. That doesn’t happen with this catalog.

Frequently Asked Questions

Does this catalog cover the FD5LT variant?

Yes – the FD5LT is explicitly listed in the title and appears in the track frame and brake sections.

How do I find a part number for the brake foot control if I only have a grid reference?

The grid reference for brake foot control is C101 on page A-16. That page shows the exploded diagram with numbered callouts and a table with OEM part numbers, description, and quantity. If you have the grid from a previous repair (like B-15 for hand brake), you can flip directly there. The numerical index at the front also lets you look up by the group code (e.g., C101) if the grid isn’t handy. Since this is an original 1989 print, the part numbers match the factory parts system exactly – no aftermarket revisions that change fastener grades or skip seal sizes. That’s why shops that rely on it see fewer comebacks.

You don’t have to gamble on aftermarket part numbers or squint at fuzzy scans. This is the same 76-page catalog Fiatallis issued in 1989, with the same grids, callouts, and indexing that let you order the right brake seal, sprocket segment, or hydraulic fitting the first time. Access the Factory Manual and put it on your tablet or print the pages you need for the job.
