Installation notes
The bellhousing is fixed to the transmission with 4 bolts. All 4 bolts are 7/16-14 NC x 1¼". Always use new bolts during restoration. Torque to correct specification in a cross pattern for even face contact. Always verify bellhousing alignment on transmission before final tightening.
Compatibility
Fits all Willys L-134 and F-134 bellhousings in combination with T84 (WWII) or T90 (civilian) transmissions. Note: these are bellhousing-to-transmission bolts — NOT the engine-to-bellhousing bolts, which are 3/8-24 NF.
Historical context
Standard bolt specification for WWII Willys MB and Ford GPW jeeps, continued unchanged in civilian CJ-2A, CJ-3A, CJ-3B and military M38 variants. These 7/16" coarse thread bolts were robust enough for heavy military service.
