Do you know the part number for a 1956 F40 water pump? Where to get a rebuilt one? October 21, 2016.
The original part number for the water pump is 830514M91 which was replaced by part number 830691M91. The pump is available from AGCO/MF dealers for around $100, Jack’s Small Engines, on online MF parts retailer sells it for $95.70 plus shipping, but I believe you can purchase it from a number of after-market parts suppliers like Steiner Tractor Parts which sells it as their part number MFS050 $49.95 plus shipping. Most of these come with a gasket, but make sure. The gasket is part number 1750079M2, and is available from AGCO/MF dealers for around $3.50. Steiner sells it as their part number MFS2127 for $1.50.
