MyFishFinder.com Just like iceshanty but warmer
Other spring is probably wore out too.should replace both.
Looks like a Jiffy 30. Remove the shoe assembly, make sure the spring is a Jiffy 30 spring, hook up the new spring (not easy to do) I use a heavy duty hose clamp to compress the 2 shoes to the driver shaft assembly, reinstall the shoe assembly making sure spacing of both shoes to the auger outer drum drive is equal.
I had the same problem with my StrikeMaster "Lazer Mag" last year, it would continue to turn slowly at idle speed same as your Jiffy (dangerous). I did not know what was wrong and couldn't find a repair shop near me so I left it as is. Now that I know what might be wrong I will pull the transmission apart and check the springs. I hear D-Rock Ice Center 175 Old Hwy 8 SW New Brighton, MN 55112 tel: 651-639-0446 maybe able to supply the springs or complete clutch assembly. Anyone know of a shop closer to Western New York?
This spring looks EXACTLY like the one that came out of my jiffy 30 transmission. Earthquake is owned by jiffy. Jiffy won’t sell just the spring, they make you buy the entire assembly. $60! This might be worth a try, be leery of previously used springs!https://www.ebay.com/itm/293510000778
