Morgen Mfg G-248 1987 Parts Catalog – Factory Reference

You’re staring at a busted concrete pump, the G-248. Hydraulic lines are weeping, the hopper is cracked, and the parts guy on the phone keeps reading you numbers that don’t match anything on the machine. That’s because he’s looking at a third-party cross-reference. Morgen Mfg G-248 1987 Parts Catalog is the only document that shows you what actually came on that unit when it left the factory in the late 80s. I’ve torqued head bolts on enough engines to know that guessing a part number costs you an afternoon and a return shipping label. This 21-page catalog kills that guesswork cold.

Every bolt, washer, seal, and subassembly in this PDF was drawn and numbered by Morgen’s own engineers. The OCR excerpt on page 1 alone lists 69 parts for the F-1 General Assembly – from the 50-gallon hydraulic oil reservoir (209-005) right down to the 3/8 flat washer (307-847). If you need to know which 5/16 lock washer goes on the engine cover, it’s right there: part 301-332. That level of specificity is what keeps a job moving. You don’t order a “5/16 flat washer” and hope it fits; you order 301-332 and it drops in.

F-1 General Assembly: What the Drawings Actually Show

The catalog’s main assembly section (pages 1 through 3) covers the complete G-248 unit – gas and electric hydraulic pump variants, the pumping cylinders, linkage guards, tire and wheel assemblies, and the control panel. It’s not a service manual; there are no step-by-step tear-down instructions. But if you’re rebuilding that machine, you need to know what part number the inner jack (055-077) carries before you call the dealer. Page 1 gives you that. The drawings are exploded-view style, so you can see where each piece lives relative to the others. For a concrete pump with dozens of hydraulic fittings and fasteners, that’s the difference between a one-day repair and a week of hunting.

21 Pages of Factory Parts Breakdown – No Missing Numbers

Twenty-one pages. That’s the entire document. It sounds thin compared to a full service manual, but every page is packed with part numbers, quantities, and parent assemblies. Look at page 2: the lunette eye assembly (201-931) breaks down into a castle nut, cotter pin, eye, and flat washer – each with its own factory number. If you need a replacement hitch or wheel hub, the hub assembly on page 3 (210-156) lists grease seal, inner bearing, inner race, idler, hub, outer race, outer bearing, spindle washer, spindle nut, cotter pin, grease cap, and wheel stud. That’s 13 line items for one hub. Try getting that from an aftermarket site.

Aftermarket Cross-Reference vs. OEM Part Numbers – A Shop Owner’s Perspective

I’ve had guys walk in with a “universal” part that sort of fits but takes two washers and a grinder to make work. That’s not a repair, that’s a field modification. This catalog gives you the exact Morgen Mfg number. When you call the dealer – or search online – you use that number. The 40B18 sprocket with 3/4 bore (305-168) is different from the 40B18 with 17/16 bore (305-169). An aftermarket list might call both “40B18 sprocket.” Then you get the wrong bore and your pump doesn’t drive. The 1987 publication date means this catalog matches the original build specs for the G-248. Revisions are noted (see Rev. 1/87 on page 3). You can trust that the 8-1/2 long #2 straight link chain (042-086) is the exact chain the factory used.

Fastener Specs and Hard-to-Find Hardware

Concrete pumps live a hard life. Bolts vibrate loose, threads strip, hydraulic fittings corrode. This catalog lists every fastener by size and type: 3/8 x 2-3/4 tension lock pin (209-982), 5/8 x 2 H.D. bolt (080-093), 3/4 nylon lock nut (200-105). If you’re rebuilding the linkage, you want that lock pin, not a substitute. The part numbers for specialty items like the 1-1/4 NPT coupler (200-168) or the double chain coupler (200-928) are critical to get right. One wrong thread pitch and you’re chasing a leak. This manual gives you the OEM number, and you order that number.

Audience Fit – Who Actually Needs This PDF

If you own a Morgen G-248 concrete pump – or you maintain a fleet of them – you need this catalog. It’s also useful for equipment restorers, salvage operators, and any mechanic who refuses to work without factory specs. DIYers who dabble in heavy equipment will appreciate the clarity: each part is drawn, numbered, and often grouped into assemblies. Beginners should pair this with the full service manual (torque values, hydraulic pressures, adjustment procedures) because this catalog won’t tell you how to rebuild the pumping cylinder – it’ll tell you which cylinder kit to order. Professional mechanics will use it to verify part numbers before placing orders, cutting down on returns and downtime.

The broader industrial equipment world uses similar documentation. Automotive Industry Overview shows how standardized parts numbering has evolved, but Morgen kept their own system. That’s why you need this specific catalog.

3 Reasons This OEM Parts Catalog Belongs on Your Bench

1. Every part number is from the original Morgen Mfg print – no re-interpretations, no “supersedes” that don’t fit.
2. The exploded views show spatial relationships: where the 095-496 hopper connects to the 209-005 reservoir, how the 051-150 pumping cylinder aligns with the 041-151 compensating cylinder.
3. Fastener callouts are complete with thread size, length, and finish (e.g., 5/16 flat washer, 3/8 NPT vented plug). You can order hardware that matches the factory assembly.

Where This Manual Fits in Your Library

It’s a parts catalog, not a service manual. That means you use it when ordering, not when wrenching. But if you’re rebuilding a G-248, you keep it open next to the service manual. The two work together: the service manual tells you steps and torque values; this catalog tells you exactly which part goes where. For example, the control panel (209-970) is shown as assembly item 19 on page 1. If you need a new control panel, you order 209-970 – not “a control panel for a Morgen pump.” That precision saves money and headaches.

One last thing: there are no torque values in this document. Don’t expect a spec sheet. It’s a parts catalog, and it does that job perfectly. If you need the charge pressure for the hydraulic system, you need the service manual. But if you need the part number for the hydraulic pump adapter (309-094) or the Woodruff key (305-664), this is your answer.

Does this catalog include repair procedures or torque specs?

No. It’s a parts catalog – assembly drawings and part numbers only. You need the separate service manual for procedures and torque values.

How many pages are in the PDF?

21 pages total, including the cover and revision notes. The main F-1 General Assembly takes the first three pages; remaining pages cover sub-assemblies and optional equipment.

What year was this catalog published? My G-248 is a 1988 model – will it match?

Published 1987, with a revision note Rev. 1/87. It covers unit numbers G-248 thru (the OCR cuts off). For an ’88 unit, it should be identical unless Morgen issued a later revision – but without a more recent catalog, this is the best factory source available.

Can I use this to order parts for other Morgen models?

No. This catalog is specific to the G-248. Part numbers for other models (e.g., G-300) will differ. There are cross-reference catalogs, but this one only covers the G-248 assembly.

This isn’t a fancy coffee-table book. It’s a 21-page slice of 1987 factory engineering that keeps your concrete pump running with the right parts. If you work on a G-248, Access the Factory Manual and stop running to the hardware store three times a day.
