Swepco 201 Infusion, gravity and tight nuts

[Jadams1]

I drained my gearbox and removed the bottom cover plate and checked the three nuts that fasten the guide fork and they were tight as the day they left the factory. The internals of the tranmission from what I could see from the bottom looked good. I filled the transmission with fresh Swepco 201 with the help of gravity. The Swepco oil I drained looked pretty clean for 23,000 miles so I don't expect to see any significant improvement.

John,
In the last photo, are you using a gravity-feed for the Swepco? Does that work?

I've used a NAPA Auto Parts plunger pump to fill mine, and I can't seem to do it without getting some oil onto the floor, as oil dribbles out if I'm not careful. I wonder if this gravity-feed will work cleanly?

[Jadams1]

Gravity worked great and is free. I measured out 3.0L into a separate container and kept topping off the funnel. Then I added a little more until I got a slight dribble out of the fill hole. It toook around 35 minutes to fill by gravity. Before I filled the tranny, I warmed up the Swepco by letting sit over a heating register in the house for a while.

I did the same thing. Warmed the Swepco by placing bottle in buket of hot water first. didn't think of attaching funnel to ladder though. I stood there with a funnel in one hand and warm swepco in the other. 15-20 minutes later, i had a small blue puddle on the floor (kitty litter cleaned it up nicely) and 3 quarts were in.

Being rather lazy I heated mine in the oven set at 110 degrees so it flowed nice, put the hose all the way to the bottom of the jug, held a rag over the top and pressurized the jug to about 10 PSI, filled the tranny in a couple of minutes and only had a little dribble.

The caution note on this is that you NEVER get the jug over 150-160 as they get pliable and only use enough air pressure to force it out which is why you use a rag instead of tapping the cap and putting in a shrader valve (Dont ask as it was really ugly).

ugly and expensive I imagine.

- I take it you are a tai chi master?

I do mine the same except I hang the funnel from the rafters, A hot summers day helps the issue.

It's a 2 beer job.

No, but the thought did run through my mind...

I made my own pump using some tubing and compressed air. Scroll down to my post in this pump thread for instructions.

You can always take the tranny out of the car and turn it upside down. And I have heard you can do that while leaving the motor in the car. Uhhm, or was is the other way round, take the motor out and turn the car upside down...

Seriously, make sure you have a good seal on the shift fork access cover, these paper gaskets are not worth their 3 cents. After replacing mine with a new gasket and having cleanded the flanges good it still leaked until I used Hylomar to seal it up for good.

Jadams1, I just finished (about 20 mins ago) draining my gear oil and replacing it with Swepco. I used your gravity method and it took about an hour. I should have warmed the oil to make it flow faster, but I was not in a hurry. It was cool because I had my 8 year old under the car as I was explaining the process. It is never too early to get kids started!

Thanks for the tip, David

I just wanted to say I used the method in the photo above & it took all of 6 minutes to get swepco in (after heating it in water).

I used a measu-funnel (promo pic from http://www.hopkinsmfg.com/10704.html):



This thing has an on/off valve & a lid & measures 1 quart!! Each quart took about 2 minutes to drain!! The thing fit nice a snuggly into my clear tubing so I could see the fluid drain!

NOT A DROP HIT THE FLOOR, AWESOME

Thank you pelicans. The old pump is now in the garbage!!!!

I just use a hand pump and pump it in at room temp in 5 minutes.

Same here. Then you only have to clean a smaller hose vs the long one used for gravity.

[khamul02]

5 minutes of "pumping" vs 100% 6 minute labor free process

. . . Let me think about it

Hey! That looks exactly like my "rig" (except my ladder is wood not fiberglass). Good idea posting a picture, I've tried describing the "gravity fill procedure" a couple times, with, no doubt, less success than your picture. I generally bleed (pressure bleeder) the brakes at the same time, that way I'm doing something while waiting to refill the funnel as the SWEPCO slowly runs into the tranny.
