Review 8 published standard models, key dimensions, reversible manganese jaw dies, pitmans, eccentric shafts, bearings, toggles, tension rods and discharge-setting spares.
Introduced in 1906, the McLanahan Universal is an overhead-eccentric, single-toggle jaw crusher. Current options include standard shim or hydraulic-shim adjustment and H-Series fully hydraulic adjustment while running. This page covers models, key dimensions, wear parts, drives and supports needed for spare-part identification. Before manufacture, check nameplate, serial number, general arrangement, drawings and used parts.
The 8 models and metric values below follow McLanahan's Universal Jaw Crusher brochure. CSS is the closed-side jaw opening measured tooth tip to tooth tip.

The numbers on the diagram correspond one to one with the rows below.
| No. | Component | Location | Applies to |
|---|---|---|---|
| 1 | Stationary jaw | Nearly vertical stationary jaw at the left of the side view | Universal Jaw |
| 2 | Movable jaw | Inclined movable jaw in the side view | Universal Jaw |
| 3 | Flywheel | Large circular flywheel in the upper side view | Universal Jaw |
| 4 | Base frame | Base frame beneath the jaw assembly | Universal Jaw |
Separate conditions at moving and fixed faces, upper side walls, lower discharge areas and frame protection. Material pages support initial selection. Confirm final material, tooth profile, thickness and heat treatment against model, ore, wear patterns and drawings.
Movable Jaw Die
Mounted on the pitman, reciprocating with the eccentric mechanism to compress feed. The image is generic, not a McLanahan part. Check Universal model, tooth profile, top/bottom orientation, effective thickness, clamping and the mating fixed jaw die.
View the common part page →
Stationary Jaw Die
Fixed to the frame to form the stationary crushing face. The image is generic, not a McLanahan part. Larger machines may use segmented fixed dies; check quantity, clamps, wedges and installation order.
View the common part page →
Upper Cheek Plate
Protect upper chamber walls from feed impact, lateral compression and uneven local wear. The image is generic, not a McLanahan part. Distinguish left and right, then check hole spacing, profile and adjacent jaw clearances.
View the common part page →
Lower Cheek Plate
Near the discharge end, these usually experience stronger sliding abrasion and local material trapping. The image is generic, not a McLanahan part. Check left/right and upper/lower positions, discharge range and jaw-die overlap.
View the common part page →
Pitman Toe & Barrel Liner
Protect the pitman toe and internal support area; these replaceable items formed part of the 2015 Universal maintenance improvements. The image is generic, not a McLanahan part. Confirm position and construction against the specific installation drawing.
View the common part page →
Clamp Plate, Wedge & Smash Plate
Fixed-die clamps, key wedges, heel wedges and frame smash plates retain the die and protect the frame. The image is generic, not a McLanahan part. Check holes, inclined faces and locking direction as a set for each position.
View the common part page →Confirm the four-bearing support, single-toggle motion and two adjustment arrangements against the specific Universal installation revision. Identical part names do not establish interchangeability across models or designs.
Pitman & Eccentric Shaft
The eccentric shaft drives the pitman's single-toggle crushing motion. The image is generic, not a McLanahan part. Check journals, eccentricity, bearing seats, keyways, end threads, flywheel side and pitman fit.
View the common part page →
Spherical Roller Bearings, Housings & Seals
Universal crushers use four bearing positions to support the eccentric shaft and pitman. The image is generic, not a McLanahan part. Enquiries require bearing designation, clearance, journals, housing bores, seals and lubrication configuration.
View the common part page →
Toggle Plate & Toggle Seats
The toggle transfers crushing load and provides mechanical protection when uncrushable material enters. The image is generic, not a McLanahan part. Check the plate, front and rear seats and contact faces as a matched set.
View the common part page →
Tension Rod, Spring & Retaining Assembly
Maintain toggle-system contact and stable pitman return. The image is generic, not a McLanahan part. McLanahan recommends stocking tension rod assemblies; check length, thread, springs and end connections.
View the common part page →Flywheel, Sheave & V-Belt Drive
Flywheels store energy and stabilize the crushing cycle; sheaves and V-belts transmit motor power to the eccentric shaft. Check Universal model, flywheel side, diameter, groove profile, keyway, bushing, speed, guards and motor configuration.

Shim or H-Series Hydraulic Adjustment
Universal offers standard shim or hydraulic-shim adjustment and H-Series fully hydraulic adjustment while running. The image is generic, not a McLanahan part. Keep these structures distinct; they are not interchangeable.
View the common part page →No. The model narrows the equipment range, but serial number, age, adjustment structure, jaw profile and site modifications may differ. At minimum provide nameplate, serial number, drawings, used parts and assembly dimensions.
Not directly. Standard machines use shim or hydraulic-shim adjustment; H-Series uses fully hydraulic adjustment while running. Confirm cylinders, wedges, guides, controls and interfaces for the specific revision.
No. Jaw dies rely on work hardening under impact and compression; cheek plates see a different balance of impact and sliding wear; toggles also provide overload protection. Confirm materials, sections and heat treatments separately.
Provide complete nameplate, serial number, model, feed opening, CSS, material and particle size, jaw profile and remaining thickness, left/right cheek plates, bearing designation, adjustment design, drawings and used-part dimensions. We use these for identification, material assessment, manufacturing coordination, quality control and delivery.
