Fan Motor

Hi everybody!

I found the part number on the radiator fan motor in my 1994 WestCoastER CAT 3116 powered rear pusher.

Itís a Haldex 1820025

I called a Thomas dealer near me.
They said that part was unavailable , but y they had some in stock in Memphis. Only want $1500.00 for it.
HmmmÖ

Iím thinking thatísa bit much.

Iím looking at pulling the motor and associated hydraulics.

Anyone on here done something similar?

Itís a passenger side radiator.

Plenty of room after I take the pump and fan assembly off for a new electric fan setup.

Iíve done this plenty of times for custom engine installs in regular gasser vehicles with a front mounted radiator.

Never anything like thisÖ
Some googling says I need about 3400cfm. Thatís fairly easy to do with electric fans.

A brand new fan setup with a new controller looks to run about $250-$400 , depending on what exactly I need.
Much better than $1500 plus!

Just got to figure out if I can just plug the fan port on the power steering pump. It ďlooksĒ like an independent output, separate from the power steering lines.

Thanks for reading!

Or…
I’m an Idiot!
Just talked to AAA Bus , he’s got a motor for me!

So much better than trying to re-engineer the cooling system!

Yeah, I wouldn't use electric. It works in autos because they have a low power requirement and ram air through the grill does most of the cooling at speed anyways.

With an RE bus, you have no ram air, and all of your cooling comes from the fan.

That hydraulic fan requires a lot of hp and provides a lot of cfm. Most electric fans show fantastic cfm numbers, but those numbers usually drop like a rock when any sort of pressure differential is applied. I'd be very surprised if you can retrofit electric fans to this and not overheat.

Much better option for sure.
