PPS FLANGE BUSHING REBUILD-YOUR-EXISTING-PARALLEL-ARMS KITS
The PPS Flange Bushing “Rebuild Your Existing Parallel Arms” kits for planters make your old and worn parallel linkage arms better than new!
All of the wear takes place on replaceable parts instead of on your planter’s parallel linkage arms.
Worn parallel linkage arms and bushings are a common problem with today’s planters. Since the implementation of down-pressure enhancing products, this problem has only gotten worse.
In the past, worn parallel linkage arms and bushings have always had to be replaced with new ones. With the PPS Flange Bushing “Rebuild Your Own Parallel Arms” Kits, there is no longer any wear on the parallel linkage arms. All of the wear is on the kit’s replaceable parts.
These parts include a hardened flange bushing and a threaded hex bushing that fits into the flange bushing. The installer reams out the existing worn hole in the arm a little larger for a more precise fit for the bushings.

Ordering Guide for PPS “Rebuild Your Existing Parallel Arms” Kits
- Find the row unit with the most movement.
- Remove a bushing from a couple locations on the parallel arms and measure wear at the widest point in the hole.
- Select kit based on measurement and planter/row unit model (1-1/16”, 1-1/8”, 1-3/16”).
- Determine if planter has any aftermarket attachments directly mounted to the parallel arm holes and note them below when order is placed (Examples: row cleaners or precision meters).
- After selecting the kit that you need, place an order with the information determined above.
Basic Installation Explanation:
- Read and understand instructions packaged with the kit before disassembly.
- Taking appropriate safety measures and wearing personal protective equipment begin disassembly of the row unit.
- Using reamer in drill press with plenty of cutting fluid, ream holes in parallel arms to size associated with kit.
- Set up template included in kit on parallel arm holes and drill 3/16” pilot hole.
- Drill pilot holes out to 25/64”, run drill bit perpendicular to the arm to ensure flange bushing pin fitment.
- Using wooden block and mallet, install flanged bushings into arm.
- On row unit and support plate use 11/16” bridge reamer to ream out the holes (shorter reamer and/or right-angle chuck may be necessary for clearance).
- Begin assembly of arms with row unit and support plate, hex bushing must seat tight against support plate and row unit. Spacer washers are provided to remove some slack between the flange bushing and hex bushing head (washers must not be drawn tight to arm).
- Torque to listed specifications and follow final assembly instructions.
