 HOW TO SEND YOUR ENGINE PARTS FOR SERVICE

This is the procedure for packaging and shipping your engine parts for mail-order service;
     
1. Find a strong cardboard box. Select a box that allows 4 inches of space around the engine part.
2a. When sending in your cylinder for an overbore kit, please leave the head and power valve assembly intact, that way there are no lost parts or moveable parts that can damage your cylinder in shipping.
2b. For cylinder plating repair ONLY, please remove all spare parts.  We only need a bare cylinder.
3. The best packing material is 'bubble wrap'.  Take care to pack around the fragile parts of engine parts like the bottom skirt of the cylinder, the head's water fittings, or the crankshaft's threaded ends.
4. Enclose ORDER FORM. Print a Service/Repair or Big Bore Kit order form from your browser.
5. Regarding payment, you can pre-pay with a personal check or visa card. You can also have your parts returned shipped by pay prior to despatch by Visa/Mastercard.
6. Its best to send your parts by business post. Remember to insure your parts for at least £300 and get the tracking number. (This costs approx £3.60 per £1000.00 from Post Ofice). If there is any problem, you can track your package.
7. Send engine parts to: APTEC Ltd, Southbrook Road, Gloucester, GL4 3DN.
