Fabco TC-142 & TC-1421 Transfer Case Parts List — Every Part Number, In Stock Online

This is the complete factory parts manual for the Fabco TC-142 and TC-1421 transfer cases — all 139 numbered items from the book’s thirteen exploded-view figures (upper, intermediate and lower shafts for both models, front and PTO output shafts, hydraulic pump drive mounting, every air shift cylinder configuration, and the housing & filter group), plus the parts-not-illustrated and lubrication piping lists. Quantities differ between the two models, so both columns are shown exactly as printed. Every Fabco part number links to that exact part at Pro Gear & Transmission, Fabco’s authorized distributor. Check the nameplate on your transfer case before ordering, or call 877-776-4600 and we’ll identify what you need from the serial number. Parts marked NLA are no longer available new — superseded numbers link straight to the current replacement part.

TC-142 / TC-1421 parts manual (PDF)

Download the free interactive TC-142/TC-1421 Parts Manual (PDF) — every part number is clickable and buyable, the numbered balloons on all thirteen exploded-view figures jump to their row in the parts list, and each in-stock row has a blue Add-to-Cart arrow. The original factory book and the TC-1421 Service Manual are also free. More models on our Fabco manuals page, and full model info on the TC-142/TC-1421 model guide.
