Starter Help

I just purchase my first Cub and the starter is weak. I was able to get it to crank by pull starting it. In your experience is it better to buy a remanufactured starter or rebuild the existing one?

Local shop rebuild and it will be as good as new.

There is a discussion on "Cub Starter" directly below this topic.

A new starter purchased on the internet may be less expensive than a shop rebuild.

Depending on your ability, a do it yoursel rebuild will be considerably less expensive. Normally you need new brushes, a bushing and bearing, clean up the commutatior. Parts are available from auto parts stores and the internet.

Stick with the original and rebuild yourself or have it rebuilt. I think you will end up with a better starter in the long run

Before replacing or rebuilding. I would advise you to remove your starter and clean the ground connections between starter and bellhousing with a wire wheel or wire brush. Clean up all other batter connections as well on both ends.

Thanks for the information.

Follow Joe’s advice.

Welcome to the forum. A little more information about your new to you cub and the starter issues. Pictures would be helpful. What is model/year of your cub? Any major changes/modifications? Early models were 6v, positive ground systems. Most cubs can benefit from a full tuneup to include adjusting the valve lash, plugs, points, condenser, check the timing setting, etc. A compression test will help you determine the health of the engine. Best to give it the optimum chance for starting and running. BTW---FYI, the 6v starter does not turn very fast unless you are using a 12v battery.

Before taking the starter out of service…..check the ground (positive) connection to the battery box and check the battery box ground to the
Frame. I normally sand the connections to bare metal and then coat it with dielectric grease. Also take the starter off and sand the mounting flange and starter flange where it attaches to the tractor…again coat with dielectric grease.

You have to have a good electrical path with the 6 volt systems for them to work optimally….this also applies to the generator system as well. Clean bare metal connections and dielectric grease to prevent corrosion is your best troubleshooting start.

Also check the cables. You need AWG2 cable for the ground and to the starter if you have a 6-volt system. Most auto parts places have smaller battery cables which may have ended up on your tractor.

do you have a battery tester? are you sure the battery is good?

I do suggest rebuilding over purchasing a remanufactured. went both ways always happier overall with the rebuild.
