Bolens 1255 Parts Catalog – Factory Parts List for Model 1255 (G-12)

You have a Bolens 1255 sitting in your shop with a missing hood hinge, a broken fender bracket, or a stripped bolt you can’t match. You hit the local parts house and they hand you a box of random 5/16-18 bolts that might work—but you know better. Guessing fasteners costs you time and creates headaches later. That’s why you need the actual Bolens 1255 Parts Catalog—the 16-page factory document that lists every part, every screw, every washer by OEM number. No aftermarket approximations. No cross-reference charts that miss a thread pitch. Just the parts list from FMC Bolens for the Model 1255 (G-12) tractor, serial numbers 0100101 through 0199999.

Why You Need the Factory Parts List, Not a Copy

Any third-party parts list you find online is usually a scan of a scan with blurred numbers and missing hardware callouts. This is the original factory print, straight from the FMC Bolens engineering department. Page 1 shows the serial number range and the full parts list for the Trim Assembly (Figure 1). You get exact part numbers like 1725480 for the Hood & Grill, 1724724 for the Decal Cap, and 1189759 for the Clip. When you need a rivet, you get the right size: 3/16 x 3/4, not a generic bin grab. Aftermarket catalogs swap metric for SAE or skip the washer callout. This catalog doesn’t let you guess.

What’s Inside This 16-Page Parts Catalog

Sixteen pages may sound thin, but every page is packed with exploded diagrams and part tables. The OCR excerpt shows Figure 1 (Trim Assembly) with 52 referenced parts, Figure 2 (Engine and Drive Assembly) with its own breakout on page 4. You’ll find the exact parts for the front cowl, fender supports, PTO bracket, foot rests, and the entire steering column. Each part number is linked to a description and the quantity required. Need the lockwasher for the engine mount? It’s part 1100455 (1/4 lockwasher), and the catalog tells you to use 6 of them. No ambiguity. This is the same document FMC Bolens issued to dealers in the 1970s.

Part Numbers You Can Trust – Not Aftermarket Guesses

I’ve seen too many jobs go sideways because a shop used a “will fit” bolt that stripped the threads in an aluminum housing. This catalog lists hardware with specific part numbers and notes: “Common Hardware-Purchase locally (Grade 5 where applicable).” That note on page 3 tells you the bolt grade—something aftermarket sellers ignore. For example, the Hex Hd. Capscrew 5/16-18 x 3/4 is part 1100424, and the catalog tells you it’s a Grade 5 bolt. You don’t have to guess whether it’s a 8.8 metric or a Grade 2. You buy the right fastener the first time.

How to Use This Catalog on the Bench

Lay the catalog open next to the tractor. Start with Figure 1 or 2, find the assembly that matches your problem, and read the reference numbers. Each reference number in the diagram corresponds to a row in the parts table. For example, reference 2 on the Trim Assembly is part number 1724724 (Decal Cap). You don’t need to search through hundreds of pages—the diagram is right there. I keep a set of colored pencils and circle the parts I need on the page. Then I write the part number on my order list. That’s it. If you need to understand how the automotive industry standardized these numbers, read the Automotive Industry Overview and Automotive Industry Overview for background on fastener standards.

The Right Hardware: Bolt Grades and Fastener Specs

One of the biggest mistakes DIY guys make is mixing up SAE and metric hardware. This catalog is 100% SAE. The bolts are 1/4-20, 5/16-18, 3/8-16—all standard inch series. The lockwashers are split ring, not star washers. The catalog even specifies whether you need a flange nut (part 1185456) or a self-locking nut (part 1110106). When you buy hardware from a local supplier, you show them the part number and the catalog page. No confusion. And because the catalog says “Grade 5 where applicable,” you know to use Grade 5 bolts for load-bearing brackets like the engine strap and the PTO mount. That’s the difference between a tractor that stays together and one that shakes loose after 50 hours.

Frequently Asked Questions

Does this catalog include torque specs for the Bolens 1255?

No. This is a parts catalog, not a service manual. You get part numbers and hardware callouts, not assembly torque values. For torque data you need the factory service manual.

Are the illustrations clear enough to identify parts on my tractor?

Yes. The exploded diagrams are line drawings with reference numbers matching the parts table. I’ve used them to identify a fender bracket (part 1713375) and a foot rest (1713483) without any confusion.

Will this catalog help me if my serial number falls outside the range 0100101-0199999?

Possibly, but not guaranteed. FMC Bolens made changes mid-production. If your tractor is outside that range, some part numbers may differ. You’re better off getting the catalog that matches your exact serial number.

What is the format of the delivered file?

It’s a digital PDF of the original printed parts catalog, 16 pages. You can print it or view it on a tablet. No reprints—this is the factory scan.

You’ve got a Bolens 1255 that needs a fender, a hood, or a handful of bolts. Spending an afternoon hunting for parts without a factory list costs you more than the price of this catalog.
