Gearcase small ring / seal broke, how is this called and where to get it?

Hi!

First of all I am new to this forum and I hope it is the right section to post my question.

I have an Evinrude 30 hp 1987.

My problem is that I wanted to change new impeller. While doing this I had to remove a small black ring / seal from the gear rod. I am not native english speaking, so my first problem is always how to call these technical tools.

I had to use a screwdriver to expand the seal / ring a bit and to be able to remove it. However it broke. Now my problem is I need a new one. However I don't know how this is called and where to get it. I tried to figure it out with the parts description here: https://www.boats.net/catalog/evinrude/outboard-by-year/1987/e30ecub/gearcase

But I was not able to find this small black ring/seal. Attached a picture of what I am talking about.

How is this called and where can I buy it?

Thanks in advance for any help!

Should be part #325625 shift rod keeper. Available on this site for around 10 bucks just verify your model #. Yours should be fine though it's not broken they are split when new.
 
Take the keeper off and slide nut off, then take off your water pump parts and slide off shaft as whole lot easier to reassemble and reinstall....

Thanks for your answer, however I do not quite get it. So I am aware that I take of the keeper, the black shift rod keeper and then pull of the impeller. However the gear shaft itself is still fixed inside the outboard. But I do not need to remove it, since I only have to change the impeller (water pump)?
 
You should remove the intake screens unscrew the connector between the upper and lower shift rods.

Remove the "keeper , which is split to facilitate removal and refitting

Then you can separate the gear-case from the exhaust housing. The shift rod will pull out of the top half of the connector ( don't loose it) and through the water pump housing,

You can then unbolt the pump housing to access the impeller, sliding it up the drive shaft, Watch out for the impeller drive key.

If you have broken the keeper the you can obtain a new one from Marine engine... part number as already stated
 
What I now did is pull of the impeller by pusing it down, this was possible, since the keeper broke and fell off. The driveshaft is still in the engine, I cannot remove it, since it is fixed. When I engage gear it moves a bit down and up, but I cannot simply pull it out of the engine, since it is somehow fixed. I guess I would have to remove some screws in the upper part of the outboard to remove the connection from the driveshaft to the gear box. However I think this is not possible, because now I can change the impeller.
 
Obviously the splines in the crankshaft are rusted.----The driveshaft is stuck in there.------The driveshaft normally comes out when the lower unit is removed.-----There are no screws or connecter that holds the driveshaft in the engine.----You have to remove the driveshaft in order to do a simple job of re-assembly of the pump and lower unit !!
 
??----The driveshaft just slides out of the lower unit.-----That is after damaging the waterpump body due to the drive pin for the impeller.----And I have seen this more than once on these models !!

Sorry about that I didn't know it slid out on those.

As already said the coupling in the shift rod should be undone, the split keeper removed and the upper nut (after shifting into forward) also removed. The gearcase can then be unbolted and removed complete with drive shaft. Then the impeller housing can be unbolted and slid up the drive shaft and off to access and change the impeller.

It appears that in the OP's case the drive shaft is stuck in the crankshaft. There are no fastenings, it's just rusted in .

The OP appears to have found a way round the problem. In many models attempting to pull the drive shaft from the lower unit in this way will wreck the impeller housing as racerone says

I don't understand why the op is having problems with the split keeper on the shift rod

Ok. Thank you all for your comments. Well, the "thing" which is currently to been seen is definitely stuck/fixed in the engine. It is not possible to just pull it out.

I will now wait until I got the new impeller and the keeper. Then I will try to change the impeller and try to re-assemble everything.
 
But you have to get the driveshaft out of the engine block.----I have made up an adapter to clamp on the shaft for use with a slide hammer to get it out.
 
The shaft in your picture is the shift shaft and it is attached in the powerhead...do not try and yank it out!!! The drive shaft is the shaft that impeller is on....
 
I'm with you on that one. I guess that was what brought so much confusion... His lower is off in the picture I certainly don't see a drive shaft hanging down...
 
BertH,have you tried any penetrant on those splines? PB blaster, I do not think that is a good area to be applying heat!!

If you read through the thread again I think you will find that the OP is muddling up the drive shaft and gear shift rod.
He did say that he was not a native English speaker !

The picture shows the shift rod, which is of course still attached at the top, with the pump housing still dangling on it because at that point he had not removed the "keeper" from the end which he should have done immediately after undoing the connection between the upper and lower shift rods.

His drive shaft is hopefully where it should be, still in position in the gear case.
 
Dear all,

Once again thanks for your comments. And yes, I think I muddled up the names.

I have some questions:
I have trouble with changing the water pump unfortunately. It is not so easy for me. I am not sure how I should insert the impeller properly into the housing. First of all: Is this correctly or does it have to be upside down? So the impeller key is inserted from below or above?

When and how do I insert the impeller key?

Then about the impeller direction itself: How do I know the direction? So how do I have to insert it, is it correct?

Thanks for any help in advance!

You intall the impeller with the drive key on the shaft.----Verify that it drives the impeller.----Now lower pump housing while turning the driveshaft.-------Install the screws to hold the housing.

Clockwise from top.....your backwards, brother.

Thanks, so I have to change the impeller fingers. What about the impeller itself? Is this correct or do I have to switch it upside down? So on one side it is open where the key can be put in and on the other side it is closed. Currently as the picture shows it lies such that the opening for the impeller key is downside. Is this correct like this?

I marked it red in the picture what I am talking about.

The vanes are the wrong way in the picture.-----As already stated you put the impeller on the shaft first .----Opening for drive key down.----Then install housing while turning the driveshaft the way the motor runs.

Ok, that means when I corrected the vanes it is correct as the impeller is currently? So as the picture shows the opening for the impeller drive key is correct or do I have to turn the impeller upside down?

If I understood you correctly I think it should be fine as it is shown in the picture, because if I put the impeller on the shaft and then move it down the impeller key has to get into it from below?

One last try at helping you.-----No you put the key on the driveshaft with some grease holding it.----Put the impeller on the shaft.----Confirm that impeller turns.----Then lower the housing down while turning the driveshaft.
 
Take the impeller out of the housing

Slide it down the drive shaft with the cut out for the drive pin facing downwards

Just before it reaches the recess in the shaft fit the drive pin and continue to slide the impeller down over it.

Lubricate the impeller vanes with a little silicone grease then slide the housing down the shaft easing it over the vanes as you turn the drive shaft clockwise. This will ensure that the vanes are correctly orientated

BUT FIRST READ THE WORKSHOP MANUAL. It describes how you should have removed the gea rcase in the first place. It warns you not to remove the shifter pivot pin. It describes the impeller installation and the reassembly procedures.

It also describes the dismantling of the gear case and correct fitting of the shifter assembly which you may well have to do.

READ THE MANUAL!
