Default NGK Glow Plug Replacment for 1772 1782 D640
What is the NGK replacement part number for the D640 engine in a 1772 or 1782? Per 1711Cub and his 782D thread the D600 engine takes a Y103V plug.

D600 KB-15951-65510
D640 KB-15694-65510 subs to 65512

Not familiar with the Kubota parts system, are these the same?

Has anyone "upgraded" their 1772 or 1782 with a "hotter" plug? Is the startability of the D640 improved and no need for upgrade?

Thanks for any information.

P.S. I don't own a 1772 or 1782 but plan to search and buy one. Doing my research.

Get a 1572 or a 1772. The plastic is a pain on the 1782.

The best Upgrade I’ve made to my 1782 was replacing the starter. I used the gear reduction starter and that was better than the glow plugs which didn’t make difference. Also I changed out the radiator fan with a six blade from a John Deere 322 that made a world of difference in cooling.

I need to dig into mine. I had the head off and went through that but still can barely get it to start. Wet test doesn't make a difference, so I don't know where else I could be losing compression unless the cam is shot.

This my yanmar fan on the d640. Makes a significant difference in cooling. I don’t have any pictures of my glow plug set up. I wired in a relay so they get direct voltage from the battery instead of through the key switch.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
