I'm sorry sir but T-5300-1 is not one of our model numbers and we are not associated with TSC, which I assume to be Tractor Supply Company. As such, we are not familiar with the product you're looking to repair as it surely belongs to one of our competitors. This is the unfortunate truth of buying from folks like Northern Tool, Tractor Supply and Harbor Freight. Those competitors do not generally support their jacks and lifts with replacement parts after the sale and thus, we commonly get requests from folks who own their products and are looking for a last-ditch solution before they throw away a lift that no longer works. We'd love to help, but I apologize as we only carry replacement parts for Redline brand jacks and lifts.
