JD did an upgrade to the bolt and washer that holds the steering arm on (hidden inside the clutch housing) There is a round metal cover key 27 that snaps off to access the bolt. These are key 13 & 14 in the drawing. The upgrade is the washer key 13 goes from .250" thick to .510" thick. The bolt length changes from 1 1/4" to 1 3/4". Just a common grade 8, 5/8" (5/8-11) bolt. The torque for the bolt changes from 170lb-ft to 240lb-ft. Have one of the strong young guys tighten the bolt! Believe it or not this made a big difference in the steering wander of my JD 2030 when driving on the road. I could not justify $30 for a "washer", so I bought a second $8 washer and welded them together, on the OD of both washers. If your serial number is 204416 or higher, you already have the upgrade. If you do, it's a good idea to check the torque of the bolt. 240lb-ft Rectangle Product Black Yellow Font Light Product Rectangle Yellow Font John Deere gasoline Inline Fuel Filter - Napa Equivilent Number 3032 3-cylinder liquid-cooled Displacement 164 ci 2.7 L Bore/Stroke 4.02x4.33 inches 102 x 110 mm Power (gross) 46 hp 34.3 kW Rated RPM 2500 Torque 110 lb-ft 149.2 Nm Torque RPM 1400 Oil capacity 6 qts - 5.7 L Oil Filter - T91044 Or Equivilent - Napa Part Number is 1243 Coolant capacity 12 qts 11.4 L Intake valve clearance 0.014 inches 0.356 mm Exhaust valve clearance 0.022 inches 0.559 mm
