Leaks are never good. We could come up with a few places it would be worse to find one of these, other than a golf cart. Not to say that you want to find an issue with your caddie; we just think you would much rather have to replace the EZGO Clutch Side Crankshaft Seal than a leaky bolt on a submarine. Rebuilding an engine is tricky. We are not cutting it short at all. Buggies Unlimited would much rather do that over changing the o-ring on a torpedo tube at depth. It's all about perspective. When put on the correct scale, tearing down an engine feels like child's play.This golf cart oil seal is internally installed within the crankcase. Not to say that it is out of the league of the average golfer, but we do recommend an EZGO OEM service manual. Ask an expert at Buggies Unlimited to send you one today with your order.
