Drive and Driven Clutch Pullers
After years of being mounted, many drive and driven clutch often do not want to release easily when a replacement is needed. This problem could happen with any golf cart brand, including Club Car, EZGO, Yamaha, or others, and can be due to a variety of reasons. In such cases, a clutch puller may be required to remove the clutch.
Regarding the drive clutch, the issue is often due to the fact that the crankshaft out of the engine is a tapered fit. Therefore, once the retainer bolt is tightened, the clutch pulls onto the tapered shaft and may require some persuasion to remove. Rust and corrosion could also be other possible causes.
Regarding the driven clutch, they are often mounted onto a splined or keyed input shaft which has to taper to contend with. In this case, when they do not release, the issue is often corrosion and/or rust. Use a puller and some penetrating oil to remove.
