CL-4 and CL-5 Cam Levers are designed to work with Dane size C4 and C5 cams respectively, (SPC or BC). The distance between the center lines of the cam shaft and the lever shaft is 4x4 inches or 5x5 inches respectively as shown below. CAD files are available.

Features:

1. Lever bores allow oscillation around any commercial standard turned ground and polished shaft, (TGP).
2. Lever bores are split for easy removal and machined on both sides to allow clamping collars and or adjacent levers to ride against each other.
3. Grease fittings ported into annular groove within hub bearing surface provide means for lubrication.

1. Use CL-4 cam levers for 12 to 24 inch dial machinery, model S4x4 Samson, Dane machine bases BHP-1, MBLP-1, and MBLD-1, and model ILC-U and ILC-UL In-Line Chassis.
2. Use CL-5 cam lever for 24-40 inch dial machinery, model S5-x5 Samson, Dane machine bases MBHP-2, MBLP-2 and MBLD-2 and model ILC-L and ILC-UL In-Line Chassis.
3. For plate cams, determine the desired direction for positive drive motion either up or down.
4. Select lever style and its' pivot position based upon best location for direct tool drive or intermediate crank arm connections per application.
5. The following are stroke limits for selected cam and lever combinations. The 'minor' dimension applies to the stroke deflection from an orthagonal orientation to a position that brings the follower toward the cam hub, the 'major' applies to that toward the perimeter of the cam. The values listed apply only at the lever length indicated,'L'. To calculate the actual limit for a specific design lever length other than that listed, multiply the design length by the listed limit value and then divide by the listed length.

LEVER STYLE	FOLLOWER DIAMETER	Length "L"	CAM BLANK	MINOR LIMIT	MAJOR LIMIT
CL-4	1.125 [28.58]	10.000 [254.00]	SPC-C4	2.125 [53.98]	1.625 [41.28]
			BC-C4	2.125 [53.98]	1.500 [38.10]
			BC-C4 HARDENED	2.125 [53.98]	1.000 [25.40]
CL-5	1.250 [31.75]	17.000 [431.80]	SPC-C5	3.312 [84.14]	3.000 [76.20]
			BC-C5	3.500 [88.90]	2.625 [66.68]
			BC-C5 HARDENED	3.500 [88.90]	2.000 [50.80]

Ordering Options:

1. At additional cost, extra holes may be specified by chaining additional length dimensions and hole codes to the order number. EXAMPLE: CL-4C-8.362-1-10.500-6 would indicate a #10-24 tapped hole at 8.362 inches plus an additional .250 reamed hole at 10.500 inches. (The largest "L" dimension defines the overall length unless it is specified to us to be otherwise.)
2. Standard size cam followers are available installed at additional cost. Include the letter "F" in front of the order number.
3. Bronze Bushing inserts are available at additional cost. Include the letter "B" in front of the order number.
4. Option Ordering Example: FBCL-4C-8.362-1-10.500-6 would indicate a CL-4C lever with #10-24 tapped hole at 8.362 inches, an additional .250 reamed hole at 10.500 inches, include a 1.125 cam follower and also be fitted with bronze bushing inserts.
