Description
When you’re pulling the head on your old Massey to replace a blown gasket, those original cylinder head studs have been through decades of heating and cooling cycles. They might look fine, but stretched or weakened studs are just asking for trouble down the road. This 5-3/4″ long cylinder head stud gives you the proper clamping force you need to keep that head gasket sealed tight through years of hard work.
What You’re Getting
- Full 5-3/4″ length with precise 7/16″ UNF threading for exact fitment
- High-tensile steel construction that won’t stretch under clamping loads
- Heat-treated for the right balance of strength and fatigue resistance
- Longer design provides proper thread engagement in deeper block locations
- Roll-formed threads that are stronger than cut threads
Built for Real Farm Work
These studs are specifically designed for Massey Ferguson 35, 65, 135, 148, and 165 series tractors with Perkins A3.152 and AD3.152 three-cylinder engines. These reliable agricultural workhorses are commonly used for crop production, hay operations, and general farm maintenance, excelling at field cultivation, implement operation, and utility work on small to medium-sized farms.
Made to Last
These aren’t hardware store all-thread rods – they’re purpose-built engine studs designed specifically for your engine’s requirements. The steel is heat-treated for the right balance of strength and stretch resistance, and the threads are roll-formed rather than cut, making them stronger where it counts.
Good to Know
Professional installation is essential as proper torque sequence and specifications are critical for engine reliability. Always replace cylinder head studs as part of complete cylinder head service to ensure uniform clamping force distribution, and use appropriate thread sealant while following manufacturer specifications for torque values. Clean the block threads thoroughly with a thread chaser (not a tap), and apply a small amount of engine oil to the threads before torquing.
