Mid - Late Model Style Bolts with 12 point heads.

**BOLTS ARE SOLD INDIVIDUALLY**

Two different connecting rod and cap mating surface finishes were used and identification can be made by visual inspection. Early style connecting rods have a serrated mating surface between the cap and the rod. Middle and Late style connecting rods can be identified by smooth/machined surfaces between the cap and the rod.

Allis-Chalmers engine models: 2000 series, 3.3 and 4.9-liter series (2200, 2800, 2900, 433 & 649 types, etc.)

  1. Early style rods use hex-head capscrew with washer. The rod cap bolt holes have a 30 degree chamfer. Capscrew size used is .375" 24 x 2.00" long, grade 8, tighten those capscrews to 50 ft/lbs.
  2. Later style rods have the rod cap chamfer deleted and a new 12-point capscrew introduced. Capscrew size used is .375" - 24 x 2.00" long, grade 100, tighten those capscrews to 45 ft/lbs.

Allis-Chalmers engine models: 3000 Series, 7.0 liter series (3400, 3500, 3700, 3750 & 670 types, etc.)
  1. Early style rods use serrated rod caps with hexhead capscrews and washers. Capscrew size .437" 20 x 2.25" grade 8, tighten those capscrews to 85 ft/lbs.
  2. Middle style rods use smooth machined rod and cap mating surfaces. Socket head capscrew size .437" 20 x 2.156" long, grade 100, tighten those capscrews to 70 ft/lbs.
  3. Later style rods use smooth machined rod and cap mating surfaces. 12-point capscrew size .437" 20 x 2.156" long, grade 100, tighten those capscrews to 70 ft/lbs

ALL MODELS
When installing, use a light amount of engine oil on capscrew threads and on the underside of the capscrew head at the mating surface. Tighten hardware using a minimum of two incremental torque steps, three on higher torque hardware (7.0L). Non-serrated connecting rod caps MUST be aligned with the rod during installation. To do so, install hardware finger tight, use two feeler gauges between the rod/cap assembly and the side of journal to hold assembly snug to one side of journal. Tighten hardware in multiple steps and then remove feeler gauges.

Note: Do not use 12 point (mid - late) type hardware in early-serrated connecting rods with chamfered holes. Loosening of capscrews will occur. Early rods may be machined and balanced to accept later capscrews.
