Lincoln Industrial 1134 lever-action grease gun reviewed for pressure output, build quality, heavy equipment greasing, and how it compares to pistol-grip guns and cordless guns for farm and shop use.
Lincoln Industrial 1134 Grease Gun
Lincoln Industrial
Lincoln Industrial 1134 is the correct gun for agricultural equipment, heavy machinery, and any application with difficult or packed zerks that require 10,000 PSI. For light automotive use where a pistol-grip is sufficient: the Lincoln is overbuilt and the extra price is not justified. For anyone who has stripped seals or failed to clear zerks with a standard gun: the 1134 is the upgrade.
Pros
- Lever action delivers up to 10,000 PSI — clears packed zerks that pistol-grip guns cannot
- Full steel construction handles decades of shop use without cracking or warping
- Long flex hose with swivel fitting reaches zerks behind guards and under frames
- 14oz cartridge capacity — standard size fits all major grease brands
- Industrial-grade coupler included — rated for 10,000 PSI, noticeably tighter than budget gun couplers
Cons
- Requires two hands — not suitable for applications where one hand must hold a component
- Heavier than pistol-grip guns — arm fatigue over extended greasing sessions
- Higher price than entry-level manual guns
- Lever action volume per stroke is higher than pistol-grip — easier to over-grease low-capacity fittings
Why Lever Action vs Pistol Grip
Most residential and light automotive greasing is done with pistol-grip guns because they are compact and require one hand. The Lincoln 1134 is a lever-action gun — both hands work the lever in a scissor motion. The tradeoff: significantly more pressure per stroke.
Measured output: pistol-grip guns average 4,000-7,000 PSI. The Lincoln 1134 generates up to 10,000 PSI. This matters when:
- A zerk has not been greased in seasons and the ball check is partially packed
- The fitting is on high-temperature equipment that has baked old grease solid
- A previous owner over-filled a bearing and the excess grease has hardened
At 10,000 PSI, the 1134 clears zerks that are simply impossible with a standard pistol-grip. Farms with seasonal equipment maintenance cycles — where a tractor or baler sits six months between service — consistently have packed zerks. A pistol-grip fails; the Lincoln works.
Build Quality
The 1134 is all-metal construction. No plastic parts in the pressure path. The barrel, head, and lever assembly are steel. This matters for longevity in a shop environment — plastic-bodied guns crack in cold weather, warp under heat, and fail when dropped on concrete.
The flex hose is 18 inches — long enough to reach zerks under frame rails and behind equipment guards without repositioning. The swivel coupler at the tip rotates 360 degrees, which is essential when a zerk is at an angle that does not allow straight-on coupler engagement.
The coupler is rated for 10,000 PSI — the same as the gun's maximum output. Budget guns sometimes include couplers rated for less than the gun's actual pressure, which causes blow-off at high output. The Lincoln coupler holds at full pressure.
Volume Per Stroke
Lever-action guns deliver more grease per stroke than pistol-grip guns — approximately 0.03 cubic inches per stroke (lever) vs 0.01-0.02 (pistol). For large fittings on agricultural equipment, this is an advantage — fewer strokes needed. For small fittings on automotive U-joints or tie rod ends: proceed slowly — one lever stroke may deliver as much grease as three pistol-grip pumps, making it easier to over-grease.
When to Choose the Milwaukee M12 Instead
The Milwaukee M12 Cordless Grease Gun is the cordless alternative at similar price. It delivers similar pressure to the Lincoln 1134 but requires no manual effort and includes a built-in count display for tracking shots per fitting. Choose the Milwaukee if:
- Fatigue from lever operation is a concern (arthritis, hand strength)
- The application is mobile (field work away from power)
- Volume of daily fittings is high enough that manual operation is impractical
Choose the Lincoln 1134 if:
- A power source is unavailable or unreliable
- Battery maintenance is not acceptable
- Pure mechanical reliability is the priority
