Kubota Cylinder Head Assembly 1G677-03028 | Genuine Loaded Head for the V1505-E4B

Kubota 1G677-03028 is the genuine loaded cylinder head assembly for the V1505-E4B, the 1.5 liter four cylinder indirect injection diesel found in Kubota compact excavators, front mowers, and a wide range of OEM equipment. Supplied as a loaded assembly with the valve components installed, it is the factory answer to a cracked head, burned valve, or overheating damage. No machine shop guesswork, no mixing worn parts with new. Shipping weight is approximately 28.5 lbs.

Valley Fuel Injection & Turbo is an authorized Kubota dealer and diesel fuel injection specialist in Woodland, California, serving working equipment since 1993. If you are weighing a machine shop rebuild against replacement, a genuine loaded head usually wins on total cost and downtime once you add up valve work, seats, guides, and machining. See our Kubota engine sales, parts, and service page for everything we stock for these engines.

Application & Fitment

• Kubota V1505-E4B (parts book V1505-E4B-KEA-1A), 1.5L four cylinder indirect injection diesel

Frequently Asked Questions

Is this a complete, ready to install cylinder head?

Yes. 1G677-03028 is a loaded assembly, meaning the valve components come installed in the head. Plan on a new head gasket set and any hardware your rebuild requires. When you call, we will put together the complete parts list so the job only stops once.

My V1505 is in a non Kubota machine. Will this head fit?

Verify first. Kubota builds the V1505 for many equipment brands, and the correct head depends on the engine version and emission tier, not the badge on the machine. Read the engine serial number off the block, call us at 530-668-0818, and we will help you confirm fitment before you order.

Do I actually need a head, or could it be gaskets or fuel system trouble?

White smoke, coolant loss, and hard starting can come from a failed head gasket, a cracked head, or tired injectors. A compression or leak-down test usually settles it. As injection specialists we can also test and rebuild your V1505 injectors, see our diesel fuel injection services, so the fresh head goes back on with a healthy fuel system.
