Fabco TC-170 & TC-170PD Transfer Case — Parts, PTO Units & Manuals
The Fabco TC-170 series is a single-speed transfer case; the TC-170PD version adds a proportional differential for full-time all-wheel-drive chassis. The differential lock is air actuated — run it unlocked in normal driving and engage it in poor traction conditions, at a standstill or at any speed provided the axles are not spinning out. The factory service manual below covers both the TC-170 and the TC-170PD.
