All IMER Mortarman 120 Plus mixers purchased after Jan 2018 come with the new larger wheels STANDARD. This kit replaces the smaller 4" wheels PN 3205257
If you own an IMER Mortarman 120 or 120 Plus that was built before Jan 2018 and has the small wheels mounted alongside the drum then this is a great upgrade. The smaller wheels are prone to breaking when the MM120 is laid down heavily to push into the back of a truck or van. These new larger wheels eliminate that problem
Please look at the pictures closely to make sure your IMER Mortarman 120 has the correct mounting points for these new larger wheels.
