How to replace the crank on your recumbent bike 

Here is a quick guide instructing you on the proper procedure to successfully replace the crank arm on the recumbent bike. 

STEP 1: Using the Spanner Tool provided in the hardware package, remove the pedal. 

STEP 2: Using a flathead Screwdriver or another flat tool, pry the end cap off of the crank arm.

STEP 3: Using the 22mm Crank Puller Tool and a crescent wrench, remove the bolt from the crank arm.

STEP 4: Insert the crank puller tool with your fingers as much as possible and then tighten it with a crescent wrench. After, insert the shaft with your fingers all the way until it stops, and use the wrench to finish screwing it in. You will feel when the crank is loose enough to be removed with your hand.
