Patience

[Guest]

It's winter. It's raining. It's time to . . . what the hell. Remove the oil pan and replace the sump screen on my '78 GS1000.

The pan came off after a few raps on a wooden dowel with a rubber mallet. The bottom of the pan looked pretty good, for thirty-two years on the job. What little sludge had accumulated there came up with a paper towel wrapped around an index finger. I sprayed the cooling fins with Simple Green, then went to the coin-op car wash and blasted away with the high-pressure spray. Came home and watched the Jets manhandle the Chargers while working the nooks and crannies with Q-tips and Mother's polish. That was the easy part. That was the fun stuff.

Taking off the sump screen (see photo) will require patience. I know. I've done it before. The engineers at Suzuki chose to fasten it with three soft Phillips head screws that feel welded to the screen. Why not a hex-head or socket-head bolt? Something you can get leverage on. Lying on my back with an impact driver underneath the engine, I can deliver only abbreviated strikes. Spray some Seafoam on the screws, hoping the solvent will wick upwards into the threads (osmosis?), tap the screws, then jam the phillips head driver up while torquing with both hands. A good pump in the wrists and hands. Last time it took me about a week to get the job done, and when it was over I had a grip like a python. Some jobs you just can't rush . . . oh well, it's raining

Can you get some Vise-grips or Channel-locs on them?

Or are they above the level of the oil pan ledge?

The extra leverage would loosen them up so you can throw them away quicker. :-\\\

Those screws have loctite from the factory so try some heat on them.

good luck;


If you use the little picture icon between the letter and caption icons you can directly insert those hosted pics

P.S. I use a ratchet with a #2 screw socket attachment; If the bike is high enough you can leverage your elbow against the floor and drive the socket up. Turn with the ratchet handle; Tap the screw driver socket deep into the Phillips head before trying to turn it.

I never use impact wrenches instead use this method. If that fails I get out the hack saw. It is almost never required.

That screen is clean. I'd leave it alone.

Yea but he has a new one

I dont remember having to use an impact driver on it. If you get a good screw driver with the right tip, you can take it off by hand. I use a screwdriver with interchangeable bits for these type of screws. If they made it a hex, many guys would crank down too hard and strip the thing.

Oh yeah, the screens are washable.

The screen is pristine, I agree. But it's coming out, because I need something strenuous to do while it's still raining . . . and as posplayer pointed out, I got a new one. The old screws will become blunderbuss ammo if Al Qaeda invade Oakland . . .

So, thanks for the advice. The new order of battle is as follows:

- heat to loosen the threadlocking compound

- set the impact driver to the side, bring burly screwdriver into play

Hope to report success by this evening . . . and hope to see some of you So Cal boys at Reno Bruce's in July.

Victory . . . it's not always pretty. Step one, attack the threadlocker. Bic lighter on the screws; a couple of light taps with a mallet. Dinner, plus gin and tonic for morale. Step two. #2 phillips screwdriver, two hands, maximum effort. Defeat. Step three, #2 phillips on a socket, brace for maximum upward pressure, apply torque. Feel the bit chewing up the head. I've eaten steaks tougher than these screws. Rest. Return to house. Another gin and tonic. Inspiration. What about the lineman's pliers?

Man reading your thread I'm getting thuursty... Anybody Seen Jose

Phillips screws. Truly one of the worst inventions ever.
I was going to suggest leaning the bike over to get a better angle at using the impact. Never actually tried it but it could work. Of course you'd need a friend and a strategically placed spare car tire would help.
I thought the "leave it alone" suggestion had some merit to it.:-\\\

I read somewhere on GSR that those arent even philips, they are JIS - japanese industrial standard, i may have it wrong, but i think thats what they are called. I wonder if you had a set of those screwdrivers if that would help? I will be looking for a set for myself sometime.

 

[Nessism]

Vice Grip pliers coming in from the side would have taken those screws right out assuming there is enough room to get at them. At any rate, glad they are out so you can move forward.

The sump screen's been removed, even though, as several pointed out, it didn't need to be. Once the new screen was bought, however, and once I got a look at the infernal phillips head screws, there was no turning back . . . and speaking of the new sump screen, here's a head scratcher. It has, as you can see in the picture, the lip of the screen folded over at regular intervals, unlike the original screen, which fit over the rim of the sump like a lid fits on a jar.

This is the correct part, by the way. I did some research* and discovered that the original design was superseded some years later. (part no. 16520-45000 by 16520-45010) my question is, from an engineering perspective, is there some reason for the design change? My only guess would be that it creates small channels for the oil to flow more quickly back into the pan . . .

The phillips head screws on GS's are JIS, I bought a set and when you compare them to a #2 bit there is an obvious difference. Just put one on a screw and check the fit.

 

[Guest]

Looking at your pics of both screens, it looks as though the new design incorporates an internal "seal ring" on the inside, presumably to strengthen/seal the screen to the housing...

The older one shows only intermittent spot welds which could break, or allow larger particles to flow through the adjacent unwelded sections of screens.

I like the newer one better

if you have the proper bit, I have had about a 90% sucess rate with phillips head screw removal using a ratchet attachment. You have to press hard. :-\\\

After removal get rid of them. :clap:

You know, I seem to recall that that very idea was proposed waaayyy back in post #3. :-\\\

Can you get some Vise-grips or Channel-locs on them?

I guess it wasn't seen because it was only posted about 40 HOURS before the "victory" post.
