Fabco TC-33 transfer case parts
Gears, shafts, shift parts and overhaul kits for the two-speed TC-33, with the Fabco parts manual to look up item numbers.
The Fabco TC-33 or TC33 is a two-speed transfer case that was built with either one rear output or two, and with either a manual or an air shift. Those two choices change the shafts, the shift parts and the overhaul kits, so start by checking how many rear outputs your case has and how it shifts.
The manual also lists the parking brake mounting brackets used on some cases, and separate parts for early single rear output cases whose input shaft carries a bearing locknut.
The TC-33 parts manual
Open or download the Fabco book below. Find the part on the drawing, note the item number and the part number, and send us both with the serial number from the nameplate on the housing.
Groups in this book:
- Transfer case housing and related parts
- Shafts, dual rear output version
- Shafts, single rear output version
- Shift shafts for the manual shift
- Shift shafts for the air shift
- Overhaul kits
The last eight pages of this PDF are PTO and air shift pages from the TC-35 manual, not TC-33 pages. Use the TC-35 page for those parts.
