Bolens 1668R, 1600H Parts Catalog – Factory OEM Parts List

You pulled a seat off a Bolens 1668R, and the mounting bracket is cracked. You need the correct part number so you don’t waste a week waiting for the wrong piece. This Bolens 1668R, 1600H Parts Catalog gives you exactly that – 13 pages of factory-issued breakdowns with reference numbers, OEM part numbers, and hardware callouts. No aftermarket guesswork. I’ve seen too many guys order a “universal” seat support for a 1600H and end up drilling new holes because the aftermarket catalog left out the 3/8 flat washers (ref. 3, item 1100256). This manual stops that before it starts.

13 Pages of Factory Part Numbers

Thirteen pages doesn’t sound like a lot until you realize each page packs a dense parts grid covering the entire tractor – from the steering wheel (ref. 1, part 1747804) down to the push nut (ref. 45, part 1728072). The catalog covers serial range B050100101-B050199999 for both the 1668R and 1600H. You get exploded diagrams for the hood and grille assembly (ref. 23), the foot rests (L.H. ref. 42, R.H. ref. 20), and the tunnel assembly (ref. 50). Each line shows the number of pieces required, so you know you’re ordering one pivot rod (ref. 27, part 1736341) and not four.

What Parts Are Covered for the 1668R and 1600H?

The table on page 2 alone lists 56 reference items. It starts with the seat and goes through decals, reflectors, hardware, and the light cluster housing. Page 3 continues with steering components and shim washers. Every part that Bolens designed for these models is here. You get the grille decal (ref. 24, part 1757223), the side panel decals (ref. 54 and 55), even the official spray paint – part 1757461 for white and 1754423 for red. If you’re restoring a 1600H, this is your bill of materials.

Hardware Specifications You Need

Pay attention to the common hardware notes. Items marked with a bullet (•) are grade 5 hardware you can buy locally. The catalog tells you the exact fastener spec: for example, item 12 is a hex screw 3/8-16 x 1, item 18 is a carriage bolt 3/8-16 x 1-1/4. When you’re reassembling the fender assembly (ref. 19, part 1748574 010), you don’t want to grab a random bolt from the drawer. Use the factory spec. The catalog also lists flange locknuts (ref. 41, 3/8-16) and push nuts (ref. 45) – small parts that cause big headaches when missing.

Why Use a Factory Parts Catalog Over Aftermarket?

Aftermarket parts books often redraw the diagrams and drop the OEM part numbers. They replace them with their own internal codes that don’t cross-reference with Bolens. That’s a problem when you call a dealer and the number they have doesn’t match yours. This catalog prints the original Bolens part numbers: 1756846 for the seat, 1734115 010 for the seat support. You can take that number straight to a parts counter or an online supplier and get the exact piece. No cross-referencing, no returns. The FMC Bolens 1666 Parts Catalog – 23 Page Factory Parts List follows the same logic, and FMC Bolens 1660 Parts Catalog – 23-Page Factory Parts List and FMC Bolens 1055 Parts Catalog – 16-Page Factory Parts List OEM round out the Bolens tractor family.

Decals and Paint: Small Details That Matter

Restorations live and die by decals. This catalog gives the part numbers for every decal – the hood decal L.H. (ref. 33, part 1757240), fender decals (ref. 28 and 29), and the instruction decal (ref. 52, part 1757206). If you’re aiming for a show finish or even just a tidy machine, ordering the correct decal saves you from peeling off a generic “Caution” sticker that looks wrong. The paint specs (12 oz. spray cans) let you color-match the original red and white without guessing.

Frequently Asked Questions

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. It lists part numbers and quantities. For torque values, you need the factory service manual.

Will it work for a Bolens 1668H or other variants?

The catalog is titled for 1668R and 1600H in serial range B050100101 to B050199999. Many chassis components may cross over, but verify your serial number. Aftermarket modifications are not covered.

What serial numbers are covered?

Both models list S/N B050100101 through B050199999. If your tractor falls outside that range, some part numbers may differ. Check the specific year or contact a Bolens dealer with your serial number.

Are there exploded diagrams or just tables?

Exploded diagrams with reference numbers that map to the part tables. You can see exactly where each fastener and decal goes. That’s far better than a flat list that leaves you guessing the assembly order.

Don’t waste billable hours chasing wrong parts. Whether you’re maintaining a 1668R or restoring a 1600H, this factory parts catalog puts the correct OEM numbers in your hand. Access the Factory Manual and keep it on your bench – right next to the torque wrench.
