Bolens HT20, 2087 1977 Parts Catalog – Factory Parts List for the HT20 and Model 2087

You’re hunting for a specific washer or bracket on a 1977 Bolens HT20 or the 2087 model. You don’t want to play guess-and-check with aftermarket diagrams. That’s how you end up with a part that doesn’t fit and a wasted Saturday. This is the factory parts catalog – the same book the dealership used to order parts when these tractors were new. 23 pages, OEM numbers, exploded views, and the exact quantities you need.

Factory Parts List for the Bolens HT20 and 2087

This catalog covers both the HT20 tractor and the Model 2087, serial numbers 0200101 through 0499999. It’s not a service manual – it’s a parts identification book. You get reference numbers, part numbers, descriptions, and quantities. The exploded views show exactly where each part goes. Page 2 shows the Trim Assembly Figure 1 with callouts from 1 to 70. Page 3 starts the parts table with ref no. 1 (grille and hood assembly part 1722555).

What Does This 23-Page Catalog Include?

23 pages of part numbers organized by assembly. You get the grille and hood, instrument panel, foot pedals, fenders, seat, pivot shafts, springs, decals, fasteners, and more. Each part has a Bolens OEM number. No aftermarket cross-references – these are the original numbers you need to order from a dealer or supplier. The catalog notes serial number breaks where parts changed, like the hood stop assembly or the seat stop.

Part Numbers: Why OEM Specs Matter

When you’re reassembling a 19.5 HP HT20, using the wrong capscrew or washer can cause a vibration failure or a loose panel. The catalog lists the correct thread size, length, and quantity. For example, ref no. 7 is a capscrew 5/16-18 x 5/8 – three needed. Ref no. 8 is a flat washer 5/16 – six needed. You get that kind of detail for every fastener. That matters when you’re trying to avoid stripping threads or losing a load path.

Use the Exploded Views to Confirm Part Fitment

Page 2 is a good example: the Trim Assembly drawing shows the position of each part relative to the others. You see seat springs, pivot shafts, and the seat stop. The reference numbers on the drawing correspond to the table. If you’re not sure which foot pedal goes where, the drawing separates left and right. That prevents ordering two of the same side.

1977 Serial Number Range Coverage

Covers model 2087 from serial 0200101 to 0499999. If your HT20 falls outside that range, you may need a different catalog. The catalog itself shows sub-assembly “Serial No. 02-03” notes, meaning some parts only fit later units. Check your serial plate before ordering.

Frequently Asked Questions

Does this catalog cover the engine block?

No. This is a parts list for the tractor chassis and body components. Engine parts are listed in the engine service manual.

Can I use this to order parts online?

Yes, each part number is the OEM Bolens number. Take reference number, cross-check with supplier. But verify with serial number range first.

How are the exploded views organized?

Each figure shows a sub-assembly like the trim or fender. Part numbers are listed in a table with description, quantity, and reference number. For example, page 2 shows the Trim Assembly Figure 1 with callouts 1-70. The table on page 3 lists each part with its OEM number, description, and required count. This catalog is specific to the serial range 0200101-0499999, so if your tractor’s serial falls there, you’re covered. Some parts changed mid-production, and the catalog notes those breaks with “Serial No. 02-03” or “Serial No. 01” in the figure. Without that note, you might order a part that doesn’t match your tractor’s build. The exploded view on page 2 shows the seat assembly with springs and pivot shafts, so you can see how parts interconnect – that helps when you’re ordering a replacement and want to confirm it will bolt up without mods.

What serial numbers are covered?

Model 2087 serial 0200101 through 0499999.
