product details

This tool can remove and install O-type pinion gears!

Installing a pinion gear that is too tight can damage the motor or tool, so it's crucial to install pinion gears carefully.

Some pinion gears may need to be thermally expanded with a heat gun to ease installation. Lubricating oil is also recommended for installation.

If installation of the pinion gear remains difficult, it may be necessary to remove some material from the armature. This can be done by securely fastening the motor to a vice and running it at very low voltage with the motor tower and pinion gear removed. While the shaft is in motion, carefully apply sandpaper to remove material. It is crucial to remove material in small increments, as excessive removal can result in an overly loose pinion fit.

For tight-fitting O-shafts, Loctite 638 is the recommended adhesive. For D-type or looser fit pinions, JB weld may be required for best adhesion.

Much better than previous versions

My old ZCI pinion puller finally got to a point I had to replace it. Was pleasantly surprised to see a few noticeable changes vs older ones when I got this new one in.

- The hubs of the handles you rotate are now solid vs the old ones which were empty with very cheap welds holding the bars in place.

- The socket for the pinions is *slightly* larger making it easier to get some of the larger pinions in place.

- The dowel/shaft for pushing the armature out of the pinion is very slightly thinner in diameter, so it didn't get stuck on the pinions after pushing the armatures through.

Overall, a solid revision/update to previous versions. I don't see me replacing this for a long time.

Solid build

Solid.build, pinion pusher is a bit soft. Bent a bit with stuck pinion.

ZCI Pinion & Press Tool

Takes a little messing around with to get things aligned. Actually ended up bending one of the pegs on the threaded rod when I tried to press a pinion out. Ended up using a punch, hammer, and used the tool without the screws as a guide to knock the pinion off. For pressing new pinions on, seemed to work fine. NOTE: Solink pinions seem to fit really tightly in this tool. I was able to do it, but needed to tap it in the slot with a rubber mallet.

Amazing tool if you need to ever remove a pinion. Even heating up the pinion with a butane torch, I still cannot remove it on numerous motors. This makes swapping out stripped pinions such a breeze! If you don't know how to use one, there are many videos if you google it, it's really simple!

Just what I needed. I 2 16TPA ASG motors with broken pinions and a few others with pinions that did not mesh well. This tool saved me a lot of money. This tutorial helped out a lot https://www.youtube.com/watch?v=PTEE-YoH5Xw. In addition to that, I recommend using a thick o ring around the motor to help out with centering it since strong magnets can make that difficult.
