Brackets & Hardware

About Brackets & Hardware

Engine hardware holds the engine together and keeps it in the frame. This category lists cylinder stud and nut kits, engine fastener kits, a Polaris motor mount and engine lifting tools. The samples include Yamaha, Honda and Polaris machines, with fastener kits for the Banshee 350, the TRX450R and the Blaster 200.

Cylinder studs hold the cylinder and head down against the gasket, and they can corrode or strip on an older engine. Replace the studs and nuts as a set when you rebuild a top end, and tighten the nuts in the sequence and to the torque in your manual. An engine fastener kit bundles the bolts for a specific model, which helps when old bolts are rusted or have damaged threads. A worn motor mount can let the engine shake in the frame. The engine lifting tools are listed for particular engine types, so read the listing before ordering.

Brands in this category include Bolt, SDI, Kibblewhite and Cylinder Works. Pick your machine in the Ride Finder at the top of the page. Related parts are Gaskets, Seals & Kits, Complete Cylinders, Cylinder Heads and Engine Rebuild Kits & Components, all part of Engines & Engine Parts.

FAQs on engine studs, fasteners and mounts

Should I replace the cylinder studs when rebuilding the top end?

It is a good idea if the studs are corroded, bent or have damaged threads, or if the nuts do not tighten to the specified torque. Replace the studs and nuts together, since they work as a set and hold the cylinder and head against the gasket.

Why does the tightening order matter for cylinder nuts?

Tightening in a pattern clamps the cylinder and head evenly against the gasket. Tightening one side first can warp the parts or leave a leak. Use a torque wrench and follow the sequence and the figures in your service manual.

What does an engine fastener kit include?

It includes the bolts and screws for a particular engine, but the contents vary by listing. Compare the listing with your engine's parts diagram. Kits are made for specific models, so match your make, model and year.

Can I reuse old engine bolts?

Only if they are in good condition. Replace bolts that are rusted, stretched or have damaged threads. Some fasteners are made for one use, so follow your service manual, and use the torque value it gives.
