Description
Husqvarna LT 5005 / LT 6005 Honda GXR 120 Engine — OEM Part 594 17 70-01
This is the complete Honda GXR 120 four-stroke engine that powers standard Husqvarna LT 5005 and LT 6005 jumping jack rammers. Genuine Husqvarna OEM, supplied as a Honda assembly with the carburetor, recoil starter mounting, and crankshaft ready for installation onto your rammer's existing crankcase flange. When the engine on a healthy rammer is shot — seized crank, holed piston, snapped rod, scored cylinder, or simply too many hours to keep rebuilding — a complete engine swap costs a fraction of replacing the whole machine and lets you keep the rammer leg, spring unit, frame, and shoe you've already broken in.
Replace the Engine vs. Buy a New Rammer — Decision Framework
A complete engine replacement is the right call when:
- The rammer leg, spring unit, and shoe are still in serviceable condition. If the bottom end of the rammer is worn out too, the math shifts toward a new machine.
- The frame, fuel tank, and handle are intact. A bent safety frame or cracked tank changes the calculation.
- The engine has a hard failure — seized, hydrolocked, broken connecting rod, holed piston, scored cylinder. These are not economical to rebuild.
- The rammer has documented service history and you know what's been replaced and what hasn't. Don't drop a new engine on a machine of unknown condition.
- You're running a fleet and crews are already trained on this exact rammer. A rebuild keeps your training, parts inventory, and SOPs intact.
If two or more of those conditions don't fit your machine, get in touch before ordering — sometimes a partial rebuild kit (transmission 594 65 51-01, spring unit 594 65 71-01 or 594 65 52-01, plus a service kit) makes more sense than a full engine.

Installation Overview
Engine replacement on the LT 5005 / LT 6005 follows workshop manual section 7.4.5 — engine removal and installation. Plan for:
- Disassembly: bottom cover (8 bolts), 2 side covers (12 bolts), air filter hoses, fuel hose, carburetor hose, throttle cable, muffler, rear cover, and the 4 engine flange nuts
- Crank surface prep: the surfaces between the engine flange and the crankcase must be cleaned of all old gasket residue and debris before mounting the new engine
- Centrifugal clutch: transfer or replace the clutch (594 16 17-01) — make sure the key is seated correctly on the crankshaft before sliding the clutch on
- Engine mount torque: 45 Nm on the four flange bolts
- Other torques: centrifugal clutch nut 24 Nm, exhaust flange 26 Nm, throttle bracket 23 Nm, muffler screw 8 Nm
- Initial fluid fill: 0.3 L SAE 10W-30 API SJ engine oil, 3.0 L unleaded (max 10% ethanol)
- Break-in service: change engine oil after the first 20 hours, replace air filter and fuel filter, re-torque rammer shoe bolts
Plan for 3–4 hours of bench time on a first attempt, less if you've done one before. A torque wrench and snap-ring pliers are required.
Pair These Parts in the Same Service
While the engine is out, the following are inexpensive to replace and a pain to revisit later:
- 594 16 17-01 — Centrifugal clutch
- 594 21 56-01 — Recoil starter assembly (if the existing one is worn)
- 594 21 45-02 — One-year service kit (air filter, fuel filter, spark plug)
- 594 19 03-01 — Starter rope (if reusing the existing recoil)
- 590 32 46-03 — Fuel tank cap (replace if seal is hardened)
- Crankcase flange gasket (inspect and replace if damaged)
