Anybody Ever Replace the Bottom Unit on a Poolvergnuegen ?

[ShallowWater]

I have an old 4-Wheel Fahrvergnuegen Pool Cleaner in which the gears are stripped. I ordered an updated lower unit for the 2-Wheel model because I don't need it to be so bulky in my small pool as I want it to be manueverable. It looks like the only difference is the drive gear and two extra wheels but the top cover is the same. Anyone done this or even just swapped out the lower unit? Doing this saves over $200 on buying a completely new unit.

BTW for the youngin's amoung us..

I have successfully made the exchange of the gearset and converted it from a 4-wheel to a 2-wheel model.

The kit came with three vacuum orifice sizes and I used the biggest one but I am wondering if I should use the smallest one. Anyone know how to chose?

So I did a little bit of research and found the manual for the similar aquanuatics model from Hayward.

I’ve come to find out that I need to actually put in the small vacuum orifice to run it with my pumps pumps at low speed.

One thing I am noticing since my walls do not have a curvature where they join the pool, bottom but rather go vertical to horizontal with about a 2 inch radius the poolvernuegen will sometimes get stuck there until it goes into reverse mode. I’m a little concerned that this may end up stripping the gears again even though this is not necessarily the reason why they were stripped as the gears were already stripped on this unit when I picked it up used for free.

I must be going crazy.. Here I am in this room talking to myself.

Ha - welcome to the club.

I've been following your thread. Interesting to know the 4 wheel and 2 wheel lower units can be swapped.

Won't/shouldn't likely strip the gears, but will wear the tires sooner.

Sometimes the wheels aren't spinning so the rotation must be going somewhere. I'm just hoping it is just stalled and not stripping the gears in the drive unit.
