1955 Allis-Chalmers WD-45 Diesel

Allis-Chalmers followed the trend to diesel power in October of 1954 when they introduced the WD-45 diesel tractor. The WD line started in 1948 and, with significant upgrades, morphed into the WD-45 range late in 1953. It started with gasoline-, distillate-, and LPG-fueled engines late in 1953 and, about a year later, the diesels followed.

Allis-Chalmers acquired the Buda Engine Company in November of 1953. Buda had many diesel engines in production at the time, and Allis-Chalmers chose the Buda-Lanova 6BD-230 for the WD-45. This engine was part of a family that originated toward the end of World War II. The first ag versions debuted in 1946 Cockshutt tractors. They had a wet-sleeved 3.44-inch bore and a 4.12-inch, seven main-bearing stroke. Buda had licensed the Lanova combustion system in 1934 after having used a MAN system. The 6BD-230 was considerably downsized compared to the earlier 6DT-278 it replaced.

The WD-45 diesel began production in October of 1954 with a starting serial number of 181341. By then, the WD-45 platform was well proven. The diesel variant proved one of the more powerful diesels in its size range. Its first Nebraska test on October 11, 1955, rated it at 45.42 hp on the belt and 40.42 hp on the drawbar. At a ballasted weight of 8,305 pounds, it delivered 5,908 pounds of pull, which was in the top tier of its weight range.

The WD-45 diesel could be configured as a wide-front tractor with an adjustable wheel track front and rear, a dual narrow-front or and single-front wheel, plus a high-clearance model was an option. A-C’s snap coupling system was highly regarded by users for the ease of coupling matching A-C implements. The A-C draft control was equally well regarded. The WD-45 could also use a conventional three-point system. Power steering became an option in 1956.

A total of 90,352 WD-45s were built from 1953 to 1957. Of those, 6,509 were diesels. Generally speaking, the WD-45 is considered one of A-C’s best and most-successful tractors. Today, it’s highly regarded as a great antique pulling tractor or as a collectible. It has just the right balance and combination of features to do well in its pulling class. When A-C did a complete makeover of the tractor line for 1957, the WD-45’s place was taken by the equally popular and successful D-17.

Why do some WD45 diesel tractors have 262 gas engines, and what does this imply about their reliability?

Why Do Some WD45 Diesel Tractors Have 262 Gas Engines?

The Engine Swap Trend

It’s not uncommon to find some WD45 diesel tractors retrofitted with 262 gas engines. This trend primarily stems from a combination of factors related to the original engine’s performance and reliability.

Reliability Challenges

1. Maintenance Costs: Originally, these tractors were outfitted with diesel engines known for their costly and complex maintenance requirements. Overhauling these engines could set you back a few thousand dollars, making them a pricey option for many owners.
2. Historical Performance: Even when they were brand new, these diesel engines were notorious for being less reliable compared to their gasoline counterparts. This spurred owners to seek a more dependable alternative.

Appeal of the 262 Gas Engine

Switching to a 262 gas engine offers several advantages:

• Improved Reliability: The 262 gas engines have a reputation for being more dependable, thus ensuring users experience fewer disruptions.
• Ease of Maintenance: With simpler mechanics, the gas engines are often easier and cheaper to maintain, reducing the overall cost of ownership.
• Enhanced Availability: As these gasoline engines are more readily accessible, finding parts and service providers becomes far less challenging.

Implications for Owners

The decision to retrofit with a 262 gas engine underscores a desire for a more trustworthy and economically viable tractor. While the initial diesel engine might have had its merits, the switch to gas suggests a preference for long-term reliability and cost efficiency over the complexities of diesel maintenance. This choice reflects the practical needs of farmers and agricultural professionals who prioritize uninterrupted performance in their equipment.

What are some potential issues to consider when buying a WD45 diesel tractor?

Nothing too different from other tractors from the era. The controls were well-sited, with the hydraulic control up by the steering wheel.
A full complement of gauges, with an ammeter located near the battery box.

The WD-45 diesel could be configured as a wide-front tractor with an adjustable wheel track front and rear, a dual narrow-front or a single-front wheel, plus a high-clearance model was an option. The snap coupling system was highly regarded by users for the ease of coupling matching implements. The draft control was equally well regarded. The WD-45 could also use a conventional three-point system. Power steering became an option in 1956.

A total of 90,352 WD-45s were built from 1953 to 1957. Of those, 6,509 were diesels. Generally speaking, the WD-45 is considered one of the best and most successful tractors. Today, it’s highly regarded as a great antique pulling tractor or as a collectible. It has just the right balance and combination of features to do well in its pulling class. When a complete makeover of the tractor line was done for 1957, the WD-45’s place was taken by the equally popular and successful D-17.

The WD-45 diesel came standard with a swinging drawbar. The snap hitch was an option. It was not a three-point system, but the end result was pretty much the same. The snap hitch fit only specific implements, allowed for very easy hookups, and worked well. A traction booster system was included that worked as a draft control. Because not everyone had or wanted to buy those specific implements, a standard three-point system was available. The power-adjusted rear wheels were also standard on the diesel, and the Peltons have a pair of the optional 142-pound rear wheel weights installed.

The 6BD-230 displaced 230 ci and made 55 flywheel horsepower and 166 lbs-ft of torque. It was one of the first tractors to offer a spin-on oil filter (in this case, dual spin-ons). They were different than the type we see today and they have a very wide male-threaded base. These are reproduced cans. The crankshaft was supported by seven main bearings and the engine was wet sleeved. Like many diesels of this era, it used a Lanova power cell combustion chamber, which offered a quiet, efficient, low-pressure combustion event. It reduced the impact on the engine so that structure could be downsized. It also limited power potential, so as technology allowed direct-injected engines to match smaller dimensions, the Lanova system passed into history. The power-steering system used a pump driven off the generator, with a spool valve and servo on the steering column. According to our sources, PS was not available until ’56, so either that is an error or it was added to this ’55 later.

Potential Issues to Consider

When evaluating a WD-45 diesel tractor, it’s important to be aware of potential issues that could turn a dream purchase into a costly project. Start by examining the engine for signs of trouble. Pull the dipstick to check not just the oil level but also to look for rust, water droplets, or white frothy goo, which could indicate internal problems.

If none of these signs are apparent, remove the breather cap and inspect further. Should you encounter moisture, it’s possible that it results from frequent start-stop operations. For absolute certainty, perform a simple but effective test: if antifreeze is suspected, wipe a damp spot with your finger, remove most of it but not all, and touch it to your tongue. A sweet taste suggests antifreeze contamination, a red flag that necessitates walking away from the purchase.

Consider the brakes as well, which could present a substantial challenge if rusted tight. These inspections are key, as neglecting them could lead to unexpected expenses ranging from $6,000 to $8,000. Such diligence ensures that you invest wisely in a tractor known for its balance and pulling prowess.
