782 hydro fluid change
 

i recently got a 782 it has the cast rear end no drain valve or fill other than the plug got a new filter and rear gasket what the best way to get fluid back in it thanks kenny

Pull the rear cover. :beerchug:

The rear cover should have a plug in it, remove the plug and fill it through the hole until it starts to run out. A funnel with a piece of hose on it would be helpful.

i knew i had to pull cover but is the plug npt i thought about screwing a nipple a 90 turning the pipe up with a fill cup up high has anyone tried it holding a funnel and hose for 7 qts seems time consuming and messy thanks kenny

I use a 90. Works fine.

You can remove the top cover and pour it in till it runs out of the plug hole if you have the fenders off.

is it 1/2" npt i was thinking a nipple a 90 another nipple and like a 1/2"x1 1/2 reducer thanks

Do not use 90 in a hydro.

Edit: My bad I didn't realize that you were talking about a 90 degree elbow. Thought you were talking about 90wt gear oil.

yea done had my cocktails na just seeing if you guys have tried it with pipe 90 degree elbow you guys always make me to lmao thanks

Probably not as time consuming as driving to a hardware store to buy a 90. Shouldn't be a mess unless you cant handle a hose.:biggrin2:

As I am approaching proper fill level, I will use my pinky as a dip stick to test the level. Once I am close to the fill plug level, I pour it in the funnel by the cup full with a drain pan underneath so that I don't have a giant mess on the floor.

i already had the fittings i will give it a shot this weekend thanks all and have a good evening

I have had good luck using a long transmission funnel sticking it in the hole. It's still gonna burp on you. I've often thought about punching the hole out to 3/4" NPT.

When I filled my last couple rears with the plug in the cover I used a quart plastic bottle that had a nipple as a cap. I just filled the bottle and squeezed till empty and refilled till rear was full. I am not sure what came originally in that bottle but sure am glad I saved it.

ok got the fluid changed used the pump not a burp or a drop spilled but hydro still a little jerking seems likes lever moves alot then jumps real slow in reverse and very fast forward neutral hard to find i did not do it when i 1st got it only put about a hour on it i think i will have to pull some fenders to see what it is any one have any suggestions thanks kenny

You changed the filter, right????? I didn't believe that filters could get stopped up or cause trouble until it happened to me. After that, my 1811 is the best hydro I have.

If you did, start checking linkages and the trunion. It takes a while, but isn't difficult to remove the fender pan so you can see how things are working. Take a hard look at the trunion and the 2 springs in it. If you have to go that far, I would recommend changing the cork gasket on the pump--its cheap and they don't last forever. Lots of threads on here dealing with cork gaskets and trunion repair.
