Starter Replacement Cord

by Had Robinson

Miniplane USA stocks a 1.25m x 3.0mm 100% Dyneema starter cord which is of superior quality to the Miniplane OEM cord.  It is ordinarily used in the rigging of sailboats and is designed for extreme strength and durability.  It is also 0.25m longer than the original cord.  Taking an engine off the frame and disassembling the starter is not particularly easy and you want to do it as infrequently as possible.

Remember to thoroughly clean the insides of your starter if you are going to replace the cord.  I have tried using pure graphite powder to lubricate the internal parts of the starter but it does not have the staying power of ordinary grease.  This part of the engine is a powerful vacuum cleaner (the cooling fan) and graphite powder just gets sucked away by the air moving over the starter.  Grease will stay inside the starter but dust gets mixed in with the grease.  Eventually, everything becomes a gummy mess, especially the starter spring.  This greatly increases the wear on these parts and why routine maintenance of the starter (removing, cleaning, and re-greasing) is important.  If this is not done, the grease becomes ineffective.  It is a nuisance to do this but it is part of the routine maintenance that must be done on all paramotors.

Because the cord is a bit thinner, the extra length will fit on the spool and pilots will not engage the end of the cord as easily when starting their engines.  Not pulling the cord to the very end saves a great amount of wear and tear on the starter assembly.  If you have worn out your stock cord, this is the cord to use as a replacement.

For the "how-to" on replacing your cord, go here.  There is a notch in the spool which allows you to wind the spring without removing the cord.

When examining the starter, pilots will often find that the pulley(s) has failed or is about to.  Do not waste money on the OEM replacements.  Instead, install a quality Harken block that is available worldwide.  For info and the stock number of the Harken, go to this page and see item #4.
