1950–1979 Lower Engine Mount Studs – 10x85mm Equal Ends – N145251 - OEM Number(s) (N145251)
Replace those missing or mangled case studs the right way. These 10mm x 85mm Lower Engine Mount Studs are OEM-style replacements that thread directly into the lower case mount bosses on your Type 1 engine. Designed with equal threads on both ends (1.5 pitch), they match factory fit and function—whether you're refreshing a 36hp or sealing up a dual-port 1600cc.
These are the studs you need to connect your engine to the transaxle—without worrying about stripped threads, hacksawed bolts, or misalignment that leads to clutch chatter. If you’re working on a 25hp, 36hp, 40hp, 1200cc, 1300cc, 1500cc, or 1600cc engine (non-091 transmission), this is the correct pair.

Because Details Matter
Even small hardware like case studs can make or break your build. Cross-threaded or mismatched fasteners lead to leaks, broken bell housings, and expensive headaches. These are the correct studs for your Type 1 engine. Get ‘em in—torqued right—and drive with confidence.
