To replace a PD60 conveyor gearmotor, you’ll only need a 10 mm wrench.

Loosen the four bolts around the face of the gearmotor, then gently slide the gearmotor off the shaft.

To replace the gearmotor, line up the shaft and keys and gently slide the new gearmotor into place. Then, simply snug down the bolts and tighten with the 10 mm wrench, ensuring the gearmotor is snugly in place.

Tools required:

• 5/32″ punch
• Channel lock pliers
• Pry-bar or long flat screw driver
• 3/4″ wrench

To begin breaking a PD60 Conveyor Chain, you will start by loosening the end of the hyperend of the conveyor. Ensure the chain is loose and is able to be freed from the track. Pins will come out easier on one side. Gently tap to knock the pin loose. You can then remove the chain and pull it out of the conveyor. To rejoin the chain, pull it back together and press the pin back in the same direction that it came out. Hold it in place and use a pair of channel lock pliers to push it in the rest of the way and ensure it sits down all the way in the track. To retention the chain, use a screwdriver and pull out and tighten the nut.

Tools Required:

• 10 mm Wrench

Start by loosening the four bolts around the face of the gearmotor. Once the bolts have been removed, gently slide the motor off the shaft. To replace the gearmotor, line up and slide the motor on the shaft. Snap down on all four bolts with your fingers. Using a 10 mm wrench, tighten all four bolts to ensure the motor is secured.

Tools Required:

• 3/4″ Wrench
• 9/16″ Wrench
• 1/2″ Wrench
• Level

First, using a 1/2″ wrench, remove the four 5/16″ bolts to remove the guarding panels. Next, carefully count the number of links between sprockets; the front, left, and right side should all have the same number of links. Position your level across the conveyor, then use a 3/4″ wrench to loosen the bolts on all four corners of the lifts, just a half turn to allow the sprocket to slide. Start at the back of the lift and adjust the leveling to raise and lower the back end of the lift until the conveyor becomes level. Make sure that you are not leaving the sprocket too loose or too tight when leveling.

After the back is tensioned and level you will move on to the front and begin tightening the sprocket until it is level front to back. Then, check the tension on the bottom chain and tighten the bottom sprocket as needed. Adjust both the top and bottom to keep them level. Use a 9/16″ wrench to tighten the jam nuts on all of the leveling bolts. Next, use a 3/4″ wrench to tighten all of the locking nuts on the sprockets to keep them in place. Place your level back on your conveyor to do one final check to ensure it is level in all positions and directions. Lastly, re-install the side guards on all sides of the lift and tighten the four 5/16″ hex bolts.

Tools Required:

• 15/16 wrench
• 15/16 flat wrench
• 7/16 wrench

To adjust an overly tight endstop, use a 7/16 wrench to ensure the nuts have enough room to pivot. Then, take your 15/16 wrench and 15/16 flat wrench and place them on the 5/8 nylock nut on the pivot shaft to ensure they can also pivot. There are two pivot shafts on both the left and right side of the stops. Adjusting the pivot shafts so that they are able to pivot will allow the stop to run smoothly.

Tools Required:

• 1/2 in. wrench

Begin by placing the endstop on the side of the conveyor, center of where the pallet be stopping. Place one bolt in each side by hand to hold the endstop in place. When each bolt is in, tighten each 5/16th bolt with a 1/2 in. wrench. Do not tighten them too tight so that they have room for adjustment. Start by cycling the stop in and out while tightening one side. When one side is tight, move to the adjacent side and repeat this step. This is to ensure that everything is straight and in line when tightened.

Tools Required:

• 1/8 allen wrench
• 3/8 wrench
• 7/16 wrench

With an 1/8 allen wrench and 3/8 wrench, loosen the shoulder bolt through the shock end and remove. Then with a 7/16 wrench, loosen quarter 28 nylock nut on shock clevis, then remove shock. Installing a new shock is just as easy. Slip shock clevis over the stud, replace nut, swing shock end into place, and replace shoulder bolt. Then replace the nuts. When tightening the nylock nuts, do not over tighten to eliminate travel with the stop.

This procedure is the same for 2040, 2060, and 2060 wide conveyors. This demonstration is on a 2060 conveyor.

Tools Required:

• Masterlink
• Needle-nosed pliers
• Paint marker
• 1/2″ Wrench or socket

Chain length is very important. If it’s too long for the conveyor, it can cause negative side effects. The chain should be no longer than 1.5 inches from the bottom of the drive for standard conveyors. If your conveyor has a center drive or a chain access section, the chain should be pulled as tight as possible, joining those sections. If you cannot get the chain within an inch and a half, we offer half links that can be installed to shorten the chain.

To install the masterlink, start by putting the link in the outside plate on the far side of the chain. Then put the pin pushing over the ends of the pins. Next, install the roller sets on each side, putting the chain clips in between the rollers as you go. Finally, push the masterlink through into the side plates closest to you. Next, install the side plate over the two pins. Insert the coder pins through the holes in the masterlink, ensure each coder pin is pushed all the way through and bent back on both sides around the pin. If the coder pin is not fully bent back, it may drag or scrap the conveyor as the chain travels. Finally, to ensure you can easily spot the masterlink in the future, color the outside links with a paint marker on both sides. Afterward, be sure to reinstall the catenary guard and return the conveyor power to full service.

Tools Required:

• Masterlink
• Fish tape
• Crank handle

At Tekno, we provide different varieties of conveyors, including standard drive, bottom access, and center drive. The video demonstration features a center drive conveyor on a wide beam. The procedure is the same on all types of conveyors, however, the difference is where you will break the chain on each type. Start by installing a bare masterlink at the end of your chain, this will help you with pulling the chain through and give you something to hook your fish tape to.

Feed your fish tape through the idler end of the conveyor. If you have a center drive, you will need to feed the fish tape in through the bottom of the center drive instead. Once the fish tape comes out, hook it onto your masterlink on your chain and carefully feed the chain through while someone on the other end pulls the fish tape back. Be sure to keep your hands clear at all times.

Once you get to the center drive, you will want to engage the chain in the sprocket. Then, you can disconnect your fish tape and use your crank handle to turn. Continue turning the handle until your chain comes out the side. If you don’t have a center drive, then just continue turning until it gets to the end of the drive side. Once your chain comes out, get it onto the sprocket and pull it around the top, and then pull the chain all the way down to the opposite end of the conveyor. Once your chain comes out on the opposite side, follow the procedure for installing a masterlink according to your conveyor type.

Tools/Materials Required:

• 5/32″ Allen wrench
• Nord Communication Cable
• Serial to USB Adapter
• Computer

If your computer doesn’t have a serial port, you will need a serial to USB adapter hooked up to your computer.

First, you need to know which communication port your computer will be using. Go to the “start menu”, then “computer”, right-click and select “properties.” Go the “device manager” in the upper-left corner and find “communication ports” down the list. Expand that and locate which communication port you will be using. Remember which communication port it is so you can set it to the software.

Remove the cover over the programming access port. Plug one end of the cable into the VFD and the other into your computer.

Start with the Nord Con Software. Go to the “extras” menu at the top and select “communication settings.” Select the proper communication port under the “dialogue” box. Then, close out the “dialogue” box. Now go to “device” and then “bus scan” to scan for devices. If it finds a device, it will pop up after the scan is complete. Now go to “device” and “parameterize”, select “search for all parameters.” This will load in all of the parameters from the current drive. Now save the file by going to “file” and “save as” and select a name for it. Now you will have the settings saved from the VFD and you can switch it out with the new VFD. Remove the programming cable from the old VFD, as well as the four bolts on each side. Be sure all power is disconnected from the VFD and no cables are coming into it.

Remove the VFD from the base. Place the new VFD back on the base and tighten the bolts in place. The system will need a minimum 24-volt power to operate, so you can download the new program and reconnect all of the power supplies. Plug the programming cable back into the VFD and go to your Nord Con software. Select “device” and then “bus scan” to scan for the new drive. Once you find it, it will ask if you want to read the parameter, select “yes.” Select “device” and then “download parameters to device.” Select the file that you saved earlier and now it will download the settings to your new drive. When you’re done, select “ok,” then do another bus scan. You’ll want to check some of the parameters to make sure everything has transferred over properly and it has the new settings for your drive.
