A worn hammer in the mill cylinder or a stretched drive chain puts your mixer down until the right part shows up, and this 76-page Gehl MIX-ALL 100, MX100 parts catalog PDF (Form No. 903477) is how you order it. Exploded views break the machine down assembly by assembly, from the transmission, frame and tank through the discharge conveyor, mill frame, blower and universal drives, with every callout tied to a Gehl part number. Hydraulics cover both the self-contained and tractor-powered systems, while options and accessories (SAF trough, feed roll feeder, molasses attachment) take up much of the back half. Check your serial number first: the unloading conveyor changes at SN8107, the conveyor winch at SN7607, and the conveyor and mixer drive at SN3506. Order from the wrong breakdown and you pay freight twice. Bookmarks and a numerical index take you straight to the assembly or part number you're chasing.

Gehl 100, MIX-ALL 100, MX100 Common Problems This Manual Covers
Gehl MX100 Mix-All mill cylinder bearing housing and oil seal part numbers differ before and after SN7607
Check the Mill Cylinder parts list on page 30 and confirm your serial number first. Order the 073681 bearing kit, which includes one 073680 oil seal and one 073679 housing. On units before SN7607, remove the pipe nipple and use the 570002 grease fitting when you fit the new housing.
Manual Section: Mill Cylinder p. 30Self-contained hydraulic reservoir or oil filter element part number unclear on older serial number units
Check the self-contained hydraulics list on page 35 against your serial plate. Reservoir 064649 was used before SN10126 and 076861 after SN10125; the parts note says to order 076861 as the replacement. For the 064654 oil filter, order the 048959 element. Match the footnote letters before you place the order.
Manual Section: Hydraulics (Self-Contained System) p. 35Hydraulic pump seal kit part number unclear between the Webster and Hydreco pumps on the mixer
Check the pump callouts on page 37. Units after SN6706 use the 070864 Webster hydraulic pump, and units before SN6707 use the 064642 Hydreco pump. The service notes list two seal kits, 069248 and 077721. Order the kit whose D or E footnote letter matches the one printed beside your pump's part number.
Manual Section: Hydraulics (Self-Contained System) p. 37Unloading conveyor winch cable and drum part numbers differ on units built before SN7607
Check the Conveyor Winch section on page 18 for units before SN7607. Order the 074148 winch conversion kit. It includes the 069634 cable, 074143 winch drum, 074141 winch shaft, 073561 cable retainer, 074145 guide, 056061 clamp, 056336 spring, attaching hardware and mounting instructions. On later units, the list starting on page 20 shows a 50 link #41 chain.
Manual Section: Conveyor Winch (Used Before SN7607) p. 18PTO telescoping drive cross kit and complete driveline replacement numbers unclear for the 35 series drive
Read the tag on the drive, then check Universal Drives on page 32. The 35 series 540 RPM drive 801475 uses the 045327 cross kit. To replace the entire drive, the parts note says to order the 801476 55 series drive. The 55 series parts follow on the next page, including the 510197 cross kit and the 801477 1000 RPM assembly.
Manual Section: Universal Drives p. 32Transmission drive gear or driven gear part number no longer matches the machined gear originally fitted
Check the Transmission parts list on page 7. The gear entries are superseded by 076073 and 076074 cast gears, and the bearing collar is superseded by 520153. Match each footnote letter to its reference number before ordering. The oil seal is 064474, and the complete transmission assembly is listed as 064466.
Manual Section: Transmission p. 7Frequently Asked Questions
What are the torque specifications for standard machine hardware on the Gehl 100?
Torque specifications vary by bolt size and grade. For example, a 1/4-20 Grade 5 bolt requires 9 ft-lbs of torque when dry, while a 1/2-13 Grade 5 bolt requires 75 ft-lbs. Refer to the table on page 75 for a complete list of dry and lubricated torque values for various bolt sizes and grades. p. 75
What is the procedure for replacing the mill hammers on the Gehl 100?
The mill cylinder assembly uses 66 hammers (part 2E4D) and 65 hammer spacers (part 064706). When replacing, ensure the hammer shaft (part 064707) is properly secured with the cylinder shaft nut (part 064710). p. 30
What is the correct replacement part for the hydraulic motor on the SAF attachment of the Gehl 100, MIX-ALL 100, MX100?
The hydraulic motor for the Swinging Auger Feeder (SAF) is part number 048961 (Charlynn) or 056202 (Ross). Ensure you select the correct motor based on your specific attachment type. p. 41
How do I identify the correct replacement tire for the Gehl 100?
The company policy prohibits the sale of replacement tires for original Gehl machinery. You must purchase all replacement tires locally, using the tire size information provided with the replacement Wheel Sets. p. 2
What is the part number for the main drive shear bolt instruction decal on the Gehl 100, MIX-ALL 100, MX100 mixer?
The decal for the main drive shear bolt instruction is part number 069081. This decal should be applied to the machine to ensure proper maintenance instructions are visible. p. 4
