The Willys CJ-5 was a popular post-WWII Jeep. In fact, these Jeeps were consistently in production for nearly thirty years. Although it’s not as old as some Jeeps, restoring a CJ-5 requires the same amount of care and preparation. One of the components of your CJ-5 that might require some attention is the cutlas selective drive hubs.
To help you tackle this process the right way, read through a guide to rebuilding cutlas selective drive hubs beforehand. As you’ll see below, rebuilding these parts isn’t quite as hard as you might expect, as long as you have the right information and instructions.
A Bit of History
Although these cutlas selective drive hubs have usability outside of CJ-5’s, since it’s the vehicle we’re using as the example today, we’ll breakdown the history of this classic before getting into the rebuilding process. The CJ-5 officially began production in 1954 and remained so until 1983.
Although it wasn’t a vehicle for war purposes, this Jeep took quite a bit of inspiration from a wartime Jeep—the M38A1, which was prominently used in the Korean War. The purpose of the CJ-5 was to be an effective upgrade of the CJ-3B, the current “Civilian Jeep” model. Specifically, the CJ-5 was an attempt at appealing to U.S. civilians who were seeking out a suitable means of off-roading.
From the larger wheelbase to the more comfortable user experience, the CJ-5 introduced quite a few differences from its predecessors. One of the biggest and most innovative differences, however, was the “Dauntless” V6 engine. Although the Dauntless engine wasn’t available at the launch of the CJ-5, it officially became available for customers in 1965. This new engine offered drivers almost double the power previously provided by other Jeep models of the past.
What’s even more fascinating is that since the CJ-5 had such a long production life, it saw another upgrade eight years later. All CJ models that were officially released after 1973 had the available option of the even more powerful V8 engines.
Not only have there been upgrades to the CJ-5’s engine over the years, but there have also been quite a few special editions of the vehicle along the way. For instance, there was the “Tuxedo Park” series, which was in production between 1964 and 1967, with an aim at supplying a wide range of customers with a comfortable means of transportation.
The target audience of the Tuxedo Park Mark IV differed slightly, with the manufacturer trying to appeal to sports car enthusiasts specifically. Other special editions of the CJ-5 over the years include the Renegade series, the Golden Hawk, the Golden Eagle, and the Super Jeep.
The Renegade series can get a bit confusing because the Renegade was initially produced in 1972, whereas the Renegade I and Renegade II hit the market in 1970 and 1971 respectively. Suffice it to say, after nearly 70 years, the CJ-5 is still one of the most interesting and versatile members of the Jeep family.
Rebuilding a Classic
With the history lesson over, let’s dive into the titular rebuild. There are two distinct areas of the cutlas selective drive hubs: the hub caps and the hub bases. To begin, we’ll breakdown how to disassemble and rebuild your Jeep’s hub cap.
First, identify the coupling inside your hub cap, which is always connected to the designated chrome cap. It’s a circular component that has a collection of square chunks that stem upward.
In order to remove this coupling, you must first line it up with the corresponding grooves that will allow it to smoothly slip right out of the hub cap. Once lined up, press down on the coupling and begin spinning it. After doing this, you should be able to swiftly remove the coupling without any trouble.
Now that the coupling is out of the way, there are some additional components that should be clearly exposed. These components include the coupling spring, the coupling cam pins, and the coupling cam spring. Carefully remove these parts and set them aside.
This only leaves the central control knob in place. In order to remove the control knob, turn over the hub cap, and identify the retaining ring inside. After detaching the retaining ring from inside the hub, the control knob, the control knob seal, and the bonnet seal should also detach with ease.
At this point, the hub cap is officially disassembled. Theoretically, you can begin replacing, repairing, painting, and greasing the components inside. However, there’s one more section of the cutlas selective drive you’ll probably have to rebuild too—the hub base.
Thankfully, the hub base is very easy to take apart. Now that you’ve already disassembled the hub cap, you should be able to pop out the components of the hub base pretty easily. That being said, remember to be careful when doing so. Although many of these hub components are quite durable, there’s one that isn’t so lucky. When taking apart your hub base, you’ll find a white plastic ring inside. This ring can be easily broken if you don’t be careful when handling it.
With each part carefully removed and set to the side, the cutlas selective drive hubs are officially disassembled. Since you’re finally ready for the rebuilding process, it’s time to look at what parts need to be simply cleaned up and repainted, as well as what parts need a full replacement.
When it comes to finding replacement parts online, it’s important to do it from reputable suppliers. By choosing a quality replacement parts provider, you can expect their products to reflect that level of quality. When it comes to wartime Jeeps and post-war jeeps, we can help you find a bevy of vehicle parts. Out of the many components we have available, we have hub caps and drive flange O-ring seals.
At Army Jeep parts, we also provide customers with an expansive variety of military vehicle restoration services. Whatever form of assistance you require, seek it out from a supplier you can rely on to get the job done right.
Since you now have access to a guide to rebuilding cutlas selective drive hubs, you can use it to efficiently and successfully complete this task. There are many moving parts in a CJ-5, but with a good understanding of what makes each one tick, revitalizing this classic can be incredibly fulfilling for collectors.
