Re: MC-1 u-joint bellows full of gear oil

Is the same size lip seal used with the speedy sleeve?

Ayuh,.... Same seal,...

You need to see if the bearing slides off the gear to be sure you have the inner ring. If you can slide it off the gear, just torque to spec.
If not , it could be rolling torque method.

Re: MC-1 u-joint bellows full of gear oil

Try as I might, I can't pull the gear out of the bearings. Does this absolutely mean I have newer style stuff, and must use rolling torque method? I don't know anything about that process, so I'll go do some research on it. I'm no stranger to dial indicators, but I've never used one in this sense.

Why would somebody switch from the older style regular torque setup to the new style rolling torque setup? Just curious, I'm sure there is a good reason...

Re: MC-1 u-joint bellows full of gear oil

they blew the gears, replacement gears are .001 larger diameter and the bearings are a snug press fit .If you cant remove it by hand, tap the end of the gear while holding the bearing package to see if the bearing package loosens up a bit.

Re: MC-1 u-joint bellows full of gear oil

I did a video of the process. Have a look at that, it might help you... It's in the video section of the stickies....

It's not a difficult process, just fiddly....

Thanks for the link to the thread with the videos. I couldn't (and still can't) find that thread or those videos on the stickies. Maybe I'm just missing them or not looking in the right place?

Anyways.. I've watched some of these videos already, especially the one on the water pump service, so I'll be watching the bearing pre-load one here in just a few minutes. Hopefully that will clear up any confusion, although that picture posted above helped a lot. And that's for the awesome videos, Chris!

Re: MC-1 u-joint bellows full of gear oil

So no luck on trying to tap the gear away from the bearings... it seems to be pressed together tightly.

How should I go about breaking the bearing loose from the gear so that I can perform the rolling torque? Do I need some sort of wedge to tap in between the bearing and the other parts to break it loose?

So it seems I need an inch-pounds torque wrench to set the pre-load. Can I use a beam style torque wrench, instead of the crazy expensive dial indicator versions? Something like this seems more reasonable.



BTW, thanks for the video Chris. That cleared up the rolling torque process. It all makes sense now! How much torque do you think is a good starting point for the nut before doing the initial rolling torque measurement? 70-75ft. lbs.? Or just snug with regular socket wrench and start with the rolling torque?

Re: MC-1 u-joint bellows full of gear oil

Any thoughts on the beam style torque wrench for the rolling torque? Nobody local carries them or any other torque wrench that will work, so I'm going to have to order it.

Re: MC-1 u-joint bellows full of gear oil

If you can get a beam wrench accurate enough, no problem. I would start at about 30ft.lb. on the nut....

I bought that beam inch pound torque wrench for setting up the rolling torque on a transmission, worked perfect. Quick and easy to use.

Tip: I placed tape on the scale, so I could easily see the min-max values.

Ok, thanks for letting me know fishrdan. I went ahead and ordered it...

And thanks for the tape trick. I had been thinking it would be difficult to see the mark clearly while rotating the gear.

Re: MC-1 u-joint bellows full of gear oil

Just make sure you have the new style (rolling torque) vs the old style (pinion nut torque).... You'll need to get the assembly loosened up either way to do the reassembly. Might as well get it all apart (carefully and correctly) and be sure (and clean it real well).

Re: MC-1 u-joint bellows full of gear oil

If he can't slip the bearings off the drive gear easily, he has the new style gear and must use the 'rolling torque' method. The old style gear would have had the bearings falling off it into his hands....

Ah, I messed up my posts.. please see the following post instead of this one. :facepalm:

Re: MC-1 u-joint bellows full of gear oil

Few quick questions:

1. What's a good method to break the bearings loose from the gear without damaging anything?

2. What is a good adhesive to go between the shaft and speedi sleeve? I'm hoping for something I can pick up at the typical AutoZone/Advance store. I've seen several suggestions: Loctite 209, 242, 680; Peramatex Aviation Gasket Maker No. 3. Any suggestions?

3. Any ideas on a tool to install the speedi sleeve on the shaft? It looks like the installation tool that is provided will be too shallow. I was thinking a piece of pipe (and I think someone else used pipe?), if I can find some with the correct diameter. Since the shaft is apparently 2.25", and according to the tables on this page, I can probably get away with 2.5" PVC of either schedule 40 or 80. It looks like 2-1/2" pvc isn't so easy to find, though.

Sorry for so many questions... this project is down to the nitty gritty, the small things that a guy without a shop and experience needs to ask the pros!

1. Shop press; if you don't have one, a machine shop should and should not charge you much.

As far as the other questions, I've not done a speedi sleeve myself so can't help but I also will be interested to read what the guys recommend.

Re: MC-1 u-joint bellows full of gear oil

I saw in another thread that I may be able to just slightly separate the bearing farthest from the gear. It was also mentioned that this might be accomplished with a bearing splitter. Any thoughts on that? I've never used one, so I'm not sure. I'm seeing that I can rent this one to get the job done.

Re: MC-1 u-joint bellows full of gear oil

Few quick questions:

1. What's a good method to break the bearings loose from the gear without damaging anything?

I use a rubber/fibre mallet and just tap the end of the gear. You're not looking to remove the bearings, just reduce the preload.

2. What is a good adhesive to go between the shaft and speedi sleeve? I'm hoping for something I can pick up at the typical AutoZone/Advance store. I've seen several suggestions: Loctite 209, 242, 680; Peramatex Aviation Gasket Maker No. 3. Any suggestions?

I use Loctite master gasket sealer. Number is 515...

3. Any ideas on a tool to install the speedi sleeve on the shaft? It looks like the installation tool that is provided will be too shallow. I was thinking a piece of pipe (and I think someone else used pipe?), if I can find some with the correct diameter.

It looks like 2-1/2" pvc isn't so easy to find, though.

The first time I bought one of those sleeves, I took the installing tool and cut the centre out of it enough to slip over the shaft, then just tapped gentle on it like that....
