Luba 2 motor rubber boot sealing kit

Replacement rubber sealing kit for removing original blade guards on Luba 2. 

This mod is done at your own risk, blade guards are there for your safety!

Factory blade guards have dual purpose, they guard against possible cut injury when trying to lift the robot from the edge and they compress the motor rubber seals against the ends to prevent debris and water ingress.

This mod is for you, if you want to remove the original blade guards for less fuss with cleaning and better cutting reach for the blades.

They also cover the rubber seals sides protecting them against debris and premature breakage.

Made 4 different models

With original dimensions center holes, where you can see the ends of the rubber seals. Those have loose tolerances around the disc bracket. Available with high sidewalls or low sidewalls. 

With smaller center clearance, where it sits tightly close to cutting disc bracket, also in high or low sidewalls.

Purpose for different size sidewalls? As I'm not sure how the grass will behave between the cap and housing, there is a chance that grass can get stuck in the small clearances when motor drops and lifts the discs at different heights. Low sidewalls give the chance for the grass to fall off instead of getting stuck, I am going to test it with the higher sidewalls this cutting season.

Screw holes are optimized for slight rubber squish, so you can't overtighten them and squeeze the rubber out to much, cutout picture of sealing surfaces added. Screw heads will be clear of original cutting discs, also tested with https://www.printables.com/model/1064564-luba-awd-6-blades-cutting-disk-blades-cover
