A lot of Willys Jeep enthusiasts have problems getting their Jeep to start. This could be for many different reasons. But unfortunately, more often than not I see people misdiagnose their Willys Jeep starting problems. These people will sometimes try to fix problems that aren’t there. Well, it ends today Jeep Community. We’re going to address and hopefully fix all of your Willys Jeep starting problems.
The most common problem that I see with Willys Jeep starting problems is that starting components are mismatched. It happens all the time. Especially if your Willys has been pieced from several different places or you have a Jeep in a Basket. For example, you might have a CJ2A but your engine and drive-train components might have come from a CJ3A. If you’re shopping for willys jeep parts and buy starting components for a CJ2A, you will almost certainly have problems with your CJ2A starter because they match the model of your vehicle, but not the engine.
TIP: when you change you Willys Jeep Starter – always change your bell housing bushing at the same time.
Adding to this problem, many starters don’t have number tags or other identifying marks so you usually have to figure out which ones you have visually.
I will make sense of the combination of critical starting components for your Willys Jeep: the starter, bell housing, flywheel and ring gear.
MB, GPW & CJ2A
- or vehicles with L head 4 cylinder engine
- Autolite starter MZ4113 (has single electrical terminal on top)
- 97 tooth ring gear
- 9 or 10 tooth starter drive (they’re interchangeable)
CJ3A, Wagon, Jeepster & Truck (1946-51)
- or vehicles with the L&F head 4 cylinder engine
- Autolite starter MZ4162 or MZ4137 (both are mostly the same, MZ4162 is slightly longer)
- 124 tooth ring gear
- bell housing is easy to identify – it has a manual linkage set-up on the top
CJ3B, CJ5, CJ6 (1952+)
- or vehicles with F head engine
- Autolite or Prestolite starter MDU7004 (most common), MDU7003, MDM6004 (required no bell housing bushings, integrated into nose cone)
- 129 tooth ring gear
- larger bell housing to accommodate larger ring gear
