Crankshaft Speedi sleeve installation tip needed

[OLDSRIP]

HI all,

I have a nick on the front crank seal surface area.

I have used Speedi sleeve in the past. But I have a problem on this 97 3.4. It’s like other Toyotas too.
the inner edge of the sleeve has a flange that the installation tool uses to push the sleeve on.

The flange is removable after it’s installed.

My question is. How do you grab the flange to remove it? The inner edge is recessed about 3/8 of a inch into the pump And there is no way to get behind it t to grab it. I did cut the flange as instructed. But the installation tool flattened the area out so I couldn’t get any kind of tool behind it to bend a corner outward so it could be grabbed onto.

I ended up removing the sleeve. But would like to install another if I can find out how it’s done.

thanks,
Joe Walters

I think the pump needs to be off.

I think the pump needs to be off.

I can see where that would work. But am hoping there is a easier way.
I’m not excited about dropping the diff to remove pan, etc. it a 97 4 runner 4x4.

thanks Aztoyman,

Joe

Sometimes you can install the seal either deeper or shallower IF there is room to do so to move the seal lip out of the wear groove. Sometimes, a new seal will stop the leak even with a SLIGHT wear groove.

If your groove is bad enough and the sleeve is a must, you might have to pull the pump to get it installed properly.

I obviously can't see the access you have but if you can, use a sharp edged tool to tap around the seam to help separate the flange easier. Once it cuts away you can twist it ,cut it, whatever to pull it clear.

Good luck. I hope you find a way.

Aztoyman,

Toyota redesigned the seal. It’s now quite a bit thinner than the original.
so I may be able to set it in a better spot.

I'm dealing with a nick in the crank on this one. There is no groove.

There is no room to get a chisel or other tool to the groove with the way it’s inset.

I have decided to clean and polish the crank and try to set the seal in a better spot.

thanks,

Joe

Is the new seal thin enough to get two seals on? I've done that on a few occasions where the bore was deep enough on Caterpillar pumps. Or match the ID and OD with two thinner width seals from a seal catalog.

You might get lucky with JB Weld or similar in the nick if you have access for that type of repair.

 

[OLDSRIP]

Not sure if I can get two on or not. I will have to check into that tomorrow. I never considered that.

I do have room to get jb Weld on the nick. I’ve never done anything like that to a crank.
Is there any chance of it letting loose? Would hate to have it clog a passage.

thanks for the ideas!

Joe

It could break loose. The key is having a good clean bonding surface with "tooth". If it's smooth, it probably wont last. If it's very minor and might not leak with a new seal, I'd probably not chance it. I'm not there to see it so keep that in mind.

If it's a deep one that is definitely going to leak anyway it will probably be worth it to rough it up with a file, rotary burr or sandpaper to give the epoxy a good bond. I've used it in places as a last ditch effort to salvage a part and it's lasting to this day. Tough stuff if you mix it properly and prep the surface.

There's other products besides JB Weld. Some have metal in the mix. Devcon and others. Check online for reviews or Amazon. I've actually used it in this way UNDER a speedy sleeve because the surface was so bad.

NOTE: I probably wouldn't fill in the nick unless all other efforts failed though. Just throwing options out there.

If the repositioned seal doesn't fix it, removing the pump so you can get a speedy sleeve on might be the next step.

I understand what you are saying.

I think I will go with the cleanup and polishing as a first step. It may do what I need.

If I can fit a second seal, I may try that with the polishing.

I really appreciate your help

thanks,
Joe

I cleaned up the crank as good as possible. Put the seal in as deep as possible. With a little luck it will clear the end of the nick. It will be close. I couldn’t fit two seals.

I haven’t run it yet.

Found out this morning the harmonic balancer has a crack at the key way. I missed that when I took it apart. I have another balancer coming tomorrow afternoon. So if all goes well I’ll put it together Thursday.

Update. It’s all back together and running with no leak at this time.
I’ll be keeping my fingers crossed.

thanks,
Joe
