Top Tips for EZG Masonry Mixer Maintenance

1. Keep paddle shaft seals greased.

Grease seals daily to prevent material from leaking around the paddle shaft and getting into the bearings. If mixer is running all day, grease at mid-day and at the end of the day. Grease at the end of use will help push material that may have gotten into the seal out before it sets up. Material build up within the seal will wear grooves in the shaft causing the seals to fail, and damage shaft resulting in costly repairs.

2. Change paddle shaft seals at first sign of leakage.

If material is leaking through the seal be sure to changes seals before the material reaches the bearings causing the bearings to fail.

3. Service engine

Keeping the engine serviced prevents excessive wear on the engine. Change engine oil regularly according to engine recommendations. Keep air filter clean and change as needed. Keep excessive material build up off engine. Material build up around or on the engine can restrict air flow that keeps the engine cool.

4. Do not over adjust paddle rubbers.

Paddle rubbers should be adjust to where they are slightly away from the inside of the drum. If rubbers fold back on the paddle they are adjusted too tight. This will cause stretching and cracking of the paddle rubber. Over adjusted paddle rubbers also caused wear on the thickness of the drum resulting in holes worn in drum.

Paddle Shaft Seals

In this tip we will explain the importance of keeping the paddle shaft seals greased on any of your EZG mixers. Keeping the paddle shaft seals greased will prevent excessive wear on the paddle shaft and protect the paddle shaft bearings from being contaminated with mortar. If the paddle shaft seals are not greased on a regular basis, the seals will wear grooves in the paddle shaft. If the seals become worn out, material could get through the seal and damage the bearings.


The best time to grease the paddle shaft seals is while the shaft is turning. This allows the grease to fill more seals, leaving less room for material to get into the seals. If the grease comes out on the outside of the paddle shaft, the seals are misaligned or may be worn out.
Greasing the paddle shaft seals should be done on a daily basis and, greasing every four to five hours throughout usage is best. At the end of a work day, we recommend greasing the seals which will allow any material remaining on the seals to be pushed out before it sets up inside the seals.
Overall, keeping the paddle shaft seals greased will prevent costly repairs and downtime. Please contact Kevin Brooker with any maintenance questions you might have regarding your EZG mixers.
