John Deere 325, 328 Common Problems This Manual Covers
John Deere 325 328 hydraulic pump loses power after warm-up, loader arms move sluggishly under load
Check the hydraulic pump drive gear splines and gear shaft on page 240; the shaft should measure 19 mm with the bushing bore at 19.2 mm. Inspect the wear plate and pump body gear pockets for scoring, then torque the flange cap screws to 60–65 N·m per page 237. Drain and replace the hydraulic oil filter before reinstalling.
Manual Section: Loader p. 240Engine stalls immediately or won't restart when loader arms are raised under a heavy load
Check the park brake disk pack height on page 119; disks should measure 30.4–30.6 mm before they're considered worn. If the brake drags and won't fully release, the engine bogs down and stalls when the boom loads the hydrostatic system. Inspect the shuttle valve spool and brake piston for sticking before condemning the motor.
Manual Section: Hydrostatic Motor and Park Brake—Two-Speed Disassemble and Assemble p. 119Axle bearings feel loose or grind, machine tracks unevenly and pulls to one side during turns
Measure axle bearing rolling drag torque on page 70; specification is 4.52–13.56 N·m. Readings outside this range point to worn or damaged bearings that let the axle shift under load, causing uneven tracking and side pull. Remove the axle housing, weighing roughly 33 kg, and inspect bearing races and seals for scoring or pitting before replacing.
Manual Section: Axles and Suspension Systems p. 70Loader arm pivot pins and bushings show excessive play, boom sags at full extension
Torque the upper pin cap screws on page 221 to 320 N·m; the lower pin cap screws share the same 320 N·m spec. If the boom still sags after retorquing, check the taper pin cap screws on page 301, torqued to 620 N·m, and the lower pivot pin cap screw at 73 N·m. Replace worn bushings rather than shimming the pins.
Manual Section: Loader p. 221Hydraulic oil filter clogs within days of replacement, restriction warning light stays on
Torque the hydraulic oil filter manifold cap screws on page 303 to 37 N·m and verify the restriction switch is torqued to 2.7–5.4 N·m; an over- or under-torqued switch triggers false warnings. If clogging is real, check upstream for contamination and drain the hydraulic oil tank before installing a new filter element.
Manual Section: Loader p. 303Frequently Asked Questions
How to reset hydraulic system on John Deere 325 328 skid steer?
The manual describes a "Hydrostatic and Hydraulic Start-Up Procedure" to remove air from the system. After connecting hydraulic lines, start the engine at half idle and operate steering, boom, and arm functions for 3 minutes. Stop the engine, check the hydraulic oil tank level, and repeat the operation for another 3 minutes to ensure air removal. p. 88
What are the replacement specifications for Hydraulic pump?
The High Flow Hydraulic Pump has no serviceable components and must be replaced as an assembly if any parts are worn or damaged. p. 248
What are the general torque values for unified inch bolts and cap screws on the John Deere 325 and 328 Skid Steer?
General torque values for unified inch bolts and cap screws vary by thread size and grade, and whether they are lubricated or dry. For example, a 1/4 inch Grade 5, 5.1 or 5.2 bolt requires 9.5 N·m (7 lb-ft) when lubricated and 12 N·m (9 lb-ft) when dry. Always refer to the detailed chart on page 40 for specific values, noting a ±10% tolerance unless otherwise specified. p. 40
What are the R134a refrigerant and oil capacities for the air conditioning system?
The total system volume for oil is 232 mL (7.85 fl oz), with a compressor precharge volume of 220 mL (7.43 fl oz). The R134a refrigerant weight is 1475 g (3.25 lb). If any section of hose is removed and flushed or replaced, add 3 mL of oil per 30 cm (0.1 fl oz per ft) of hose. p. 183
What is the specified charge pressure during the hydrostatic and hydraulic start-up procedure?
During the hydrostatic and hydraulic start-up procedure, the charge pressure should reach 1965 kPa (19.6 bar, 285 psi) within 5 to 10 seconds after starting the engine at slow idle with steering levers in neutral. If the charge pressure remains below 350 kPa (3.5 bar, 50 psi) for more than 10 seconds, stop the engine to prevent pump and motor damage.
