Your name, return shipping address , phone number and brief description of the work to be done should be included inside the box. Using a printed copy of our Work Order Form is a great way to include this. The parts that are to be refurbished are the only other things that should be sent.

Cylinders: If sending cylinders in for refurbishing, we do not need the old pistons! For powervalve models, we recommend including the disassembled powervalve blades. Exhaust studs, head studs, etc can typically be left in.

Crankshafts: Remove any non-essential parts such as flywheel keys, PTO couplers, etc. If you struggle to get a PTO coupler off or do not have the right tool, that is OK. We can do that as part of your order.

Heads: For four stroke heads, depending on the work to be done, we suggest contacting us to determine the best prep parts.

Other parts: Rotary shafts, rotary covers, counterbalance shafts, and anything else that you would like serviced are pretty straight forward.

Choose a sturdy cardboard box or storage tote that can be zip tied shut. Box or tote should be large enough to allow room for padding material between the box and the contents and between individual parts if multiple things are shipped in the same box.

For smaller items like rotary covers and small single cylinders, USPS Medium Flat Rate boxes are an easy and cost effective way to get parts to us.

Mid-sized parts like twin jet ski models or larger single cylinders may , USPS Large Flat Rate boxes are still a good option.

When sending larger or heavier items, diaper boxes, moving boxes from a home improvement store or storage tote that can be zip tied shut are often the best option.

If you are sending components for an entire engine, it is often better to split it into several medium sized boxes as opposed to trying to fit everything into one box. Many carriers also charge a premium for shipments that weigh over 50 pounds.

Start by lining the box with crumpled old newspaper, bubble wrap, bath towels, or any other padding to separate the contents from the box. Wrap each part as well before placing them in the box multiple items are being shipped to prevent them from damaging each other.

Boxes are strongest and will hold their shape best when full so after all contents are in the box, be sure to fill all void space to prevent parts from moving!‍ ‍Heavy parts in boxes that are not completely filled can slide and punch through the side.

Packing peanuts or air packers can be used as a bulk filler but we recommend using these only in conjunction with one of the other methods listed above as the parts can more easily shift in packing peanuts and come into contact with the outside of the box.

Tape is cheap! Use ample packing tape (not duct tape) on all joints of the box. Create a grid pattern on the top and bottom to ensure there is adequate support.
