2828353001 Self-Propelled Unit (UPGRADE TO VERSION B KIT)

Perfect upgrade and fix for my 2017 LM2100SP that had stopped self propelling suddenly. Would be nice to have written instructions included, but was able to repair without it.

Worked great. Would have been nice if there was instructions because there is so little available in EGO products on YouTube

Part is accurate and works like new. Good job great replacement

After installing the parts, my self propelled is now working like new but the kit is missing a few things:
1 When i buy a upgrade kit i would expect some instructions
2 The one wire (I think it was yellow or orange) had a connector on the driver board of the kit, but was soldered on the mower. Some type of solderless connector should come with the kit. I soldered mine and put shrink tube over the connection.
3 The 2 drive wires from the board to the motor have no insulation! I would imagine if these two connectors touched it upgrade would fail. Shrink tube or insulated connectors are needed.

I was intimidated when there were no instructions, but it's fairly easy to figure out. The design is completely different from version A, so can't use that for reference. The mower WILL NOT START unless the top black plastic cover is reinstalled. I originally left it off in case I needed to reinspect the wiring. The new circuit board has the capacitor on it already, so you won't need the external one attached by wire to the old board. All the wires match up fine and all but one have quick connections. Inexplicably, 1 wire (the brown one I believe) has to be snipped, stripped, and attached manually by either twisting and using electrical tape or with connectors you have to provide.

Another tip - The nut to the height adjustment mechanism must be removed. It's tight getting a wrench in there (10mm worked for me). Try adjusting the height of the mower to it's highest setting to get the most clearance to work with.

Oh, and the black and white wires coming off the new axle motor will be very hard to get through hole to the wiring section at the top of the mower. I bolted it in before realizing this, but had a grabber tool. I'd recommend running string through the hole and taping it to each wire then bolting the axle in. Then you can pull the wires through.

The top speed seems a touch slower than the Version A unit, but it pushes freely when the self propel function isn't being used. The old unit had a lot of drag when pushing the mower manually.
