Fabco TC-1702 Transfer Case Parts List — Every Part Number, In Stock Online

This is the complete factory parts list for the Fabco TC-1702 transfer case — a two-speed, two-shaft, air-shift case with vertical mounting, built in seven assembly variations (873-0060-001 through -007) that differ by high ratio (0.85:1 or 1.00:1), speedometer type (mechanical or electronic) and, on -007, the absence of the front declutch group. All 135 part numbers and every one of the 111 numbered items are listed below exactly as the factory prints them, with the quantity for each of the seven assemblies side by side. Every Fabco part number links to that exact part at Pro Gear & Transmission, Fabco’s authorized distributor. Parts marked NLA are no longer available new; superseded numbers link straight to the current replacement. If you are not sure which assembly you have, check the nameplate or call 877-776-4600.

TC-1702 service & parts manual (PDF)

The TC-1702 book is a combined service and parts manual — alongside the parts list it carries the full service section: recommended lubricants and oil-change intervals, cleaning and inspection, removal and installation, assembly precautions and the torque-specification drawings. Download the free interactive TC-1702 Service & Parts Manual (PDF) — the whole 56-page book, with every part number in the parts section clickable and buyable, a blue Add-to-Cart arrow on each in-stock row, and the numbered balloons on both exploded-view sheets wired to jump straight to that item’s row in the list. The original factory book is also free. More models on our Fabco parts & service manuals page, and full model information on the TC-1702 model guide.
