Bolens 1656 Parts Catalog – OEM Fastener and Decal Identification for 16 HP Tractor

Description

If you’re chasing parts for a Bolens 1656 tractor and guessing which capscrew matches that fender bracket, you’re wasting time and money. I’ve seen guys grab a 5/16-18 x 5/8 screw from the bin and wonder why the thread strips. That’s not a mystery – it’s skipping the spec sheet. This Bolens 1656 Parts Catalog is the factory document, 15 pages of part numbers, descriptions, and quantities that the assembly line used. No aftermarket reprints, no third-party guesswork. If you need the exact # 1101072 flat washer or the right lock nut for the heat shield, it’s here.

Decal Placement and Part Numbers

The first thing you notice in this catalog is how much detail Bolens put into decals. Page 1 alone lists nine different decal part numbers: engine cover (1727239), hood (1727240), instrument panel (1727419 and 1727420), two identification decals (1725542, 1725543), a trademark decal (1735814), and the hydro lift decal (1727410). Each one has a quantity and location. If your 1656 is missing a decal or you’re restoring the trim, you order the exact factory part – not a generic sticker. The catalog even shows left-hand and right-hand variants. That matters when the dealer asks which side.

Fastener Sizes and Types: Why OEM Specs Matter

Look at the reference numbers on page 2. Bolens didn’t just say “screw” – they specified 5/16-18 x 5/8 capscrews (1185672), 5/16 lockwashers (1185675), self-locking nuts (1101108), and Tinnerman nuts (1185456). Mixing up a 5/16-18 with a 3/8-16 in a fender support bracket will get you a stripped hole or a broken bolt. This catalog gives you the exact part number to order. Need to know the torque for those capscrews? That’s not in a parts catalog – you’d grab the service manual – but the fastener type tells you the grade. Don’t substitute.

3 Key Sections: Trim Assembly, Seat, and Fender Supports

The catalog is organized by assemblies. The trim assembly (Figure 1) covers the hood, decals, instrument panel, and side panels – that’s references 1 through 40. Then the seat section (refs 60, 35, 34, 36-39) gives the spring, latch, and stop rivet. The fender and support group (refs 69-78) includes left and right fenders (1721925, 1721924), fender supports (1721900, 1721902), and the mounting plate (1714576). Each part number ties to a quantity-on-hand count. If you’re rebuilding a 1656 from a basket case, you use this list to order every nut, bolt, and decal in one shot.

What This Parts Catalog Does Not Cover

This is a parts list, not a service manual. You won’t find torque specs, repair procedures, or wiring diagrams. For engine overhaul or transmission work, you need the factory service manual. But if you’re stuck on “what size capscrew goes in the side panel bracket?” – this catalog answers it. The 1656 uses a mix of 1/4-20, 5/16-18, and 3/8-16 fasteners. The part numbers direct you to the correct bolt length and thread pitch. No guessing, no return trips to the hardware store.

How to Use the Reference Number System

Each assembly page lists a REF. NO. and a REF. (the exploded view bubble number). You match the reference number to the part number. For example, reference 15 on the trim assembly points to a shoulder screw (1185872). The catalog tells you it’s a 5/16-18 x 3/4 screw, and you order that exact P/N. Some items have a plus sign (+) next to them – those are sub-assemblies that include multiple parts. The quantity column shows how many you need. For the hood decal, reference 2 calls out part 1727240, quantity 1. If you’ve got a Bolens 1656 with a cracked fender, look up reference 69 (left fender, part 1721925) and order it.

FAQ – Bolens 1656 Parts Catalog

Does this catalog include repair procedures?

No. This is a parts catalog – it lists part numbers, not how to install them.

How do I identify the correct part number for my Bolens 1656?

Locate the assembly or system you’re working on (trim, seat, fender, etc.) in the catalog. Each exploded view has reference numbers. Match the reference number to the part number in the table. Verify the description – for example, if you need a capscrew for the side panel, look at reference 75: hex head screw 5/16-18 x 1-1/4, part 1185894. Order that exact part from a Bolens dealer or supplier. If you’re unsure, check the quantity – a single part may appear in multiple assemblies, but the part number stays the same.

Is this catalog compatible with the Bolens 1666 or 1660 models?

It is not. Those models have different parts lists. Use the dedicated 1666 or 1660 parts catalog to avoid mismatches.

Can I use this catalog for a Bolens 1656 with a different engine?

Possibly, if the tractor chassis is the same. The catalog covers the 16 HP tractor platform – engine-specific parts (like decals) are listed. Verify your engine decal part number against the list.

You don’t need to second-guess every bolt on a Bolens 1656. This 15-page factory parts catalog puts the original assembly spec in your hands. Buy the part number listed, and it fits. Access the Factory Manual from AutoRepairManuals and keep it on your bench or tablet – it’s the difference between ordering the right capscrew and making a third trip to the hardware store.
