Part of the Kubota Parts Manuals.
Finding the exact factory part number for your tractor before calling the supplier is the primary focus of this 427-page Kubota L2800DT/HST Parts Catalog PDF. The manual contains 160 parts lists spanning 18 systems, covering everything from crankcase and injection pump internals to HST drivetrain components, hydraulic cylinder assemblies, front and rear axles, and electrical wiring. Every section pairs an exploded-view figure with a numbered reference table. Where Kubota revised the design mid-production, dedicated OLD PARTS figures cross-reference the superseded components so your serial number matches the right piece. If you are matching pistons, the factory oversize is +0.25mm, while injection pump shims run 0.20mm. Stop waiting on a dealer to look up numbers. Bookmarked by system and keyword-searchable, this file lets you jump straight to what you need and place your order with the correct part number in hand.

Kubota L2800DT/HST Common Problems This Manual Covers
No-crank or intermittent starting in cold weather leaves the tractor unable to turn over. p. 130
Review the electrical parts breakdown on page 130 to identify the main fuse block components. Replace any blown 5A fuses shown in the assembly list. Verify the correct relay part numbers for the starter circuit before ordering replacements for your machine.
Manual Section: Electrical SystemHydrostatic transmission drives weakly, hesitates under load, and completely loses forward motion on steep inclines. p. 148
Examine the HST input shaft exploded view on page 148 to find replacement part numbers for the drive components. Match your serial number to the correct assembly list. Cross-reference the hydraulic pump gear drive on page 275 to order the correct 18T replacement gear if the splines show wear.
Manual Section: Clutch/Transmission SystemRear implement lift is slow or nonresponsive when trying to raise the 3-point hitch attachment. p. 292
Consult the hydraulic outlet block diagram on page 290 to locate the correct pressure relief components. Order the required 0.4mm shims listed on page 292 to restore proper valve seating. Verify the lower link replacement pins match the linkage assembly drawings on page 321.
Manual Section: Hydraulic SystemEngine runs rough, produces excess white smoke, and lacks power during heavy PTO load operation. p. 35
Inspect the injection pump component breakdown on page 35 to identify the correct governor linkage parts. Order the exact 0.20mm shim thickness specified on page 37 to adjust the injection timing. Verify your engine serial number against the parts index before buying replacement delivery valves.
Manual Section: Engine SystemFrequently Asked Questions
What are the replacement specifications for fuses?
This catalog lists several fuses with specific current ratings for replacement. Options include 5A (Part No. T1060-30430), 10A (Part No. T1060-30440), 15A (Part No. T1060-30450), 30A (Part No. T1060-30510), and 40A (Part No. T1060-30520). These specifications appear in the Electrical Wiring sections for both HST and non-HST models.
What are the replacement specifications for relays?
The manual provides part numbers for specific relays. For instance, the 'RELAY STARTER' has Part No. T1060-33720, and the 'RELAY GLOW' has Part No. T1060-33710. However, detailed electrical specifications such as voltage or current ratings for these relays are not provided in this parts book.
What headlight bulb wattage does this Kubota L2800DT/HST use?
The parts catalog lists a 25W headlight bulb for the L2800DT/HST (page 97). Use this wattage when ordering a direct replacement so the bulb matches the original electrical load. The headlight assemblies are split into an old type and a new type by serial number, so confirm your serial range before buying.
My L2800 HST drives weakly or loses forward motion on hills, what does this manual cover to fix it?
This catalog covers the hydrostatic drive train so you can find and order the correct worn parts. Start with the HST input shaft exploded view on page 148 and match the assembly to your serial number. If the splines are worn, cross-reference the hydraulic pump gear drive on page 275 to order the correct 18T replacement gear.
The 3-point hitch lifts slowly or won't raise an implement, what parts does this catalog show?
For a slow or nonresponsive rear lift, the catalog shows the hydraulic outlet block diagram on page 290 to locate the pressure relief components. It also lists the 0.4mm hydraulic outlet block shims on page 292 used to restore proper valve seating. The lower-link replacement pins for the 3-point linkage are detailed on page 321.
My engine runs rough and smokes white under PTO load, which parts does this catalog identify?
The catalog breaks down the injection pump on page 35 so you can identify the governor linkage parts involved. It specifies a 0.20mm injection pump shim thickness on page 37 used to set the injection timing. Verify your engine serial number against the parts index before ordering replacement components.
