QUICK TACH 6.1 Preventative Maintenance Grease lock pin assembly (L & R) To keep the quick - tach locking pins and mechanism working freely, and to prevent pin and bushing wear, the quick tack must be lubricated every 8 hours of operations. More often in dirty applications. Lubricate the quick - tach as follows: 1 Remove any attachment from the loader, raise the boom arms, engage the boom supports, engage the park- ing brake and shut off the engine. 2 Clean any dirt build up around the linkages. 3 Lubricate the grease fittings on each of the lock pin bushings with a good quality multi purpose lithium based grease until excess shows. (fig. C4306) 4 Lubricate the tilt cylinder pivot pins.

QUICK - TACH 6.1 Removal Extend tilt cylinders 1 Remove any attachment and lower the boom arms. 2 Start the engine and extend the hydraulic tilt cylin- ders approximately 12 inches. (fig. C3880) 3 Shut off the engine and engage the parking brake. 4 Remove the bolts retaining the upper pivot pins to the quick - tach frame. (fig. C3881) 5 If this repair is being performed in a proper work shop, a portable floor jack works excellent for this next step. Place the floor jack under the quick - attach. (fig.C3881) 6 The floor jack is used to relieve the weight on the 2 (two) lower pivot pins. Remove the upper pivot pins.

7 Remove the nuts and or bolts retaining the 2 (two) lower quick - tach pivot pins to the quick - tack or boom arms. (There are two different types). (fig. C3881) 8 Remove the pivot pins using a brass drift punch and hammer. 9 Remove the quick - tach from the loader boom arms. C3880 Remove bolts C3881 Remove nut Installation Upon installing the quick - tach to the loader boom arms: 1 Make sure all pivot pins and bushings are good con- dition. Do not reuse worn parts. Replace pins and hard- ened bushings as required. 2 Use the floor jack to assist installing the quick - tach to the loader boom arms. (Or lay it down on your piece of wood. (fig.

C3881) 3 Raise the bottom of the quick - tach up to align the boom arm pivot holes and the lower quick - tach pivot bushings. Install the 2 lower pivot pins, retaining bolts and or lock nuts. 4 Swing the quick - tach up and align the 2 tilt cylinder pivot bushings with the quick - tach bushings and install the pins and retaining bolts and lock nuts. 5 Lubricate all pivots until excess grease can be seen flowing out around the bushings and pins. 6 C3882 C4214 6-4
