Motor oil and filters-check, Radiator flushed and all new antifreeze-check, Hydraulic Oil and filters-check.  Same for Generator.
Going to do all the Fuel Filters this weekend and will be ready to go.  I will say, it did give me a feeling of accomplishment

So the fan motors are on the preventive maintenance list and the steering gearbox. Getting closer. Getting everything brought up to speed is a great feeling. Glad you got em done.

Just finished, resealing the fan motors. Not a particularly technical job. Just dirty and 15 gallons of coolant and 5 gallons of hyd oil to deal with. Takes longer to clean and drain everything. Also helps to have a friend that doesn't mind getting dirty to help.

Sun strand motors looks like, no part # I could see. The shaft seals are 20x30x7mm. Got mine off of Amazon.

I saw this posted earlier in the thread and had bookmarked it
Fan Seal

But I still have not found a source for the rebuild kit. I am still researching. Seems there is a lot of different motors out there and I have to figure out exactly which mine is. I had this bookmarked too.
Fan Motor Breakdowns

I want to be prepared when I replace the radiator and have them on hand just in case.

I just replaced the shaft seal in mine. I didn't see any need to open the motors up. The shaft seal where just hard from age

I did the same as Bruce and just changed the seals. There is no reason to open the motor.

How did you guys remove old seals? I have my radiator out and plan to replace the fan seals while the motors are still in the RV fans and brackets are strapped into should mount back up to the radiator when I get it back
Thanks

Remove the fan and fan retainer and drill a small hole in the old seal and screw in a metal screw
and pry the seal out and reinstall the new seal. Put a little grease on the seal lip before installing.

hey Mike I use a small awl and punch a small hole,  use a small sheet metal screw in the hole, then a pair of pliers to pull the seal. The seal comes out very easy. To install the new seal use a deep socket or other suitable tool that will fit inside the body over the shaft, start the seal then start the snap ring, lightly tap the snap ring until it snaps in place. That way the seal goes in straight. I just don't like the drill method you have to be very careful not to nick the aluminum motor body.

Thanks Bruce, going to tackle that next week, the hydraulic lines are kind of nasty so will be cleaning and inspecting them too ,a line must have burst at one time, or maybe just oil flung from the weeping seal but they are crusted up.

I cleaned the motors and lines up twice with a pressure washer and still went through 3 shirts. Also the hydraulic fittings are JIC. If go to your local Hyd shop they have inexpensive plastic caps and plugs for the fittings helps keep the dirt out and the drips down. It will take 7 # 12 caps and plugs one #6, 5 #4

Although these are flexible lines that was when they were young. They are twenty plus years old now and have taken a set to there current position. They will flex but can be damaged if flexed excessively.

Ithe old line are " set" pretty good. I found if yo loosen the top and bottom fan bracket bolts getting the the hoses on and off is way easier.

If you are just going to change the seals and clean the area up why not do the seals where the fans are mounted? If you have a 5 gallon bucket to set on you should be able to do the complete job rite there. Clean the area up with your favorite degreaser and put the blades back on. No need to unhook the hoses the inside is clean.

I agree with Mike, just pull the fans and adapter, you will need a crank damper type puller( available at HF as a kit) and a small pair of inside snap ring pliers. leave all the hoses connected. Whole lot less mess. Yours are clean compared to mine, that have been seeping for years.

Yes dont disturb if you can help it. KISS.  Check to see if any lines are riding against each other. They will actually wear thru the steel braid.

Sounds a whole easier than pulling the lines they're really stiff, will just blow off the loose stuff and spray down with some gunk remover,
