COUNTERSUNK SQUARE HOLES FOR CUTTING EDGES AND END BITS

1986-07-01
HISTORICAL
J740_198607
To be used on cutting edges and end bits in conjunction with No. 3 head plow bolts (Ref. ANSI B18.9) typically used on off-road self-propelled work machines as described in SAE J1116. Cutting edges are further defined in SAE J737, J739 and J1304. End bits are further defined in SAE J63. 1 When section thickness exceeds A in drawing 1 (Figure 2) (countersunk one side) or B in drawing 4 (countersunk both sides), use counterbore with diameter D, as shown in cross section drawings 2, 5 and 6, or extended countersink C, as shown in cross section drawings 3 and 7. 2 The inscribed circle of the square holes shall be concentric with countersink or counterbore within 0.03 in (0.8 mm).

CUTTING EDGE - CROSS SECTIONS LOADER STRAIGHT

1985-02-01
HISTORICAL
J1303_198502
For cutting edges used on buckets for loaders defined in SAE J1057a. The dimensions are applicable to rolled, cast, forged, flame cut, and machined cutting edge sections. Straight cutting edges are defined as those whose leading edge and rear edge are parallel and, thus, are of constant cross section. For "straight cutting edge sections with bolt holes," see SAE J1304 FEB85.

CUTTING EDGE—CROSS SECTIONS LOADER STRAIGHT WITH BOLT HOLES

1985-02-01
HISTORICAL
J1304_198502
For cutting edges used on buckets for loaders defined in SAE J1057a. The dimensions are applicable to rolled and machined sections only. Cutting edge cross section thickness is limited to a maximum of 35 mm. Bolt-on tooth adapters are rarely used on loader buckets with cutting edge thicknesses in excess of 35 mm. This recommended practice applies only to straight cutting edges defined as those whose leading edge and rear edge are parallel and thus are of constant cross section. Overall cross sections to which bolt holes were added as indicated by this recommended practice were selected from those indicated per "Cutting Edge—Cross Sections Loader Straight," SAE J1303 FEB85. Selection was based on minimum section width requirements to accommodate bolt-on tooth adapters.

CUTTING EDGE—OPTIONAL CROSS-SECTIONS AND DIMENSIONS LOADER STRAIGHT

1989-09-01
HISTORICAL
J1581_198909
The purpose of this SAE Recommended Practice is to specify dimensions for loader straight cutting edge cross sections without holes and with bolt holes for mounting bolt-on teeth and tooth adaptors on loader buckets described by SAE J731. This recommended practice is intended to supplement SAE J1303 and SAE J1304 with cross sections for heavier duty applications, by identifying larger blunts, greater bevel angles, larger bolt holes, and greater bolt spacing.
