Removal of hydraulic cooling fan motor

May 15, 2022, 06:23:36 pm

Has anyone replaced the secondary cooling fan by themselves? This is the one without the thermal valve. There is a big canister (transmission cooler) in the way and it shares a mounting bar with the fan. I was hoping to pull the fan along with the two vertical mounting bars as one piece so I could deal with it on my work bench.
I was hoping to avoid messing with the transmission cooler with the coolant and the transmission fluid. 
What was your approach to this fan replacement?
I added a pic posted from another forum member.

The cooler has to be dropped out of the way. I believe Chuck did it without removing
the trans cooling lines but the antifreeze has to be removed. I did both my seals a month
ago and hung my cooler from the frame instead of off the radiator.

Like Peter posted I did not have to take the cooler lines off but did drain coolant.

Thanks Guys. That's what I suspected.  I was really hoping to avoid messing with the coolant as there is probably a lot of it and burping the system of air could be a challenge.
In my area, Mechanics willing to touch these beasts are disappearing from the ranks. So it is up to me.

Have fun it's a messy job. In doing mine I replaced all the hydraulic filters as all the hydrrualic
oil is drained and I serviced the transmission also

Yes, I did drain the hydraulic canister of the five gallons of oil and replaced the 3 filters. It was an easy job.
Seeing that the coolant and trans fluid was replaced last September, I'll re-use the coolant and leave the transmission hoses connected

That's an understatement. I drained approximately 11 gallons neatly into three clean Home Depot buckets. The surprise came when I dropped the canister and a few more gallons unexpectedly came out. What a mess.
 I mopped up and called it quits for the day while things dried out.
FYI: That canister is heavier than it looks.
