AL1 & AL3 ACTUATING LEVERS

ACTUATING LEVERS
Model AL1 and AL3
Light Duty and Heavy Duty Clamping Hub Styles

Light duty model AL1 and heavy duty AL3 clamping hub style actuating levers are used as intermediate levers between the main driving cam lever and the component to be activated. Their application is suitable when stroke amplification, reduction, or change in direction is required. CAD files are available.

PLEASE NOTE -- Our PT1 and PT2 pivot bearing dimensions have changed. They now have a slightly larger shaft. Therefore, if you are replacing an AL1 series lever with the older .375 bore, please be sure to note on the order: BORE= .375

Note: Limit for any AL1 X or Y value: Maximum = 4.000,[101.60], Minimum = 1.000,[24.40]

* - Typical Pivot Bearing and Bracket combinations.

Ordering Actuating Levers:
Please refer to above drawings for maximum and minimum X and Y values

Specify:	1.	Catalog Number AL1 or AL3	EXAMPLE: AL1-1-3.562-6 Indicates an AL1-1 single arm style actuating lever with a .250 diameter reamed hole located at 3.562 inches from the pivot bore.
	2.	Style of lever, 1, 2 or 3
	3.	"X" arm dimension. Please use 3 decimal places.
	4.	"X" Arm Hole "TA" ordering code per chart below:
	5.	"Y" arm dimension,(styles 2 & 3 only). Please use 3 decimal places.	EXAMPLE: AL3-3-3.362-1-4.000-6-A Indicates an AL3-3 90 degree style actuating lever painted OHSA yellow with a #10-24 tapped hole "TA" on the 'X' leg at 3.362 and a .250 reamed hole "TB" on the 'Y' leg at 4.000
	6.	"Y" Arm Hole "TB",(styles 2 & 3 only) ordering code per chart below:
	7.	Finish Code, for AL3 series only: A=Painted OHSA Yellow B=Un-painted

Note: Hole codes 04 and 08 not recommended for AL1 series.

Note: Should you require a keyway on an AL*-2, AL*-3, add "-K" to the order number. The added keyway will be parallel to the slot and of the same size as shown for style #1 of the same model.

Note: Though AL1-1 is shown with a non-metric woodruff key per the orginal .375 bore designed for the defunct XPT1 pivot, we ask that customers specify the key slot of their choice for this lever.
