The JDG1923A is the precision-engineered service tool for John Deere 4045 and 6068 engines—designed to extract unitized front seals and wear sleeves without prying, scoring, or damaging the crankshaft nose.

The High Stakes of Unitized Seal Removal

Modern John Deere 4045 and 6068 engines use a "unitized" seal design where the oil seal and wear sleeve are a single, press-fit assembly. Removing these without the proper JDG1923A puller is one of the most common ways technicians accidentally ruin a crankshaft.

• Crankshaft Scoring – Using a chisel or pry bar to pop the sleeve often results in deep gouges on the crankshaft nose ($3,000+ crankshaft replacement).
• Seal Path Distortion – Even a minor burr left on the crank will prevent the new unitized seal from seating, causing immediate oil leaks.
• Linear Extraction Force – The JDG1923A applies perfectly even pressure around the circumference of the sleeve, sliding it off axially rather than prying it at an angle.
• Time-Saving Efficiency – What usually takes an hour of "careful" chiseling takes 5 minutes with the correct puller.
• Professional Shop Grade — Precision-machined from high-strength steel to withstand the high-torque removal of corrosion-bound sleeves.

What is the JDG1923A Remover?

The JDG1923A Crankshaft Seal & Sleeve Remover is an application-specific tool tailored for John Deere mid-range engines. It securely engages the integrated wear sleeve, allowing for damage-free extraction during front cover service or full engine overhauls.
