  View original topic: Speedi Sleeves for Vintage VW 25-36hp Flywheels

Has anyone ever used a speedi sleeve for their VW flywheels that Porsche suppliers offer? These can help stop the notorious back nut oil leak that seeps past the rear main seal.

Are the early 356s flywheels the same as a beetles?



Please let me know, it seems like it would really help the old flywheels that we cannot buy repoped.

I've used them in many application, but not on a VW. They are great! often the finished surface is better than OEM of the shaft. You can buy them from any industrial bearing supplier.

The Porsche and the early VW crank are the same diameter.

Can anyone recommend a supplier? I see stoddard sells them for like 50 bucks. Is anyone else cheaper?

Any bearing supplier that carries SKF Bearings will have them or get them.

Ok, what do I search for on eBay? I have done a search for these and many come up, just not sure what specifically to punch in to narrow down the list.

I do not want to buy the incorrect size.

Please let me know,

Chris

I just used the speedi sleeve # and did a search for that. I'll look and see if I kept the # in my folder. I found the # at the local flaps who still know how to use paper catalogs for reference :wink:

So, from a grey haired fella, is what you're saying. 'Cause the kids certainly don't know how to work a paper catalogue.

Ok let me know when you find it.

Nope not from a grey hair, actually younger than me :shock:
Chris, I couldn't find the number but I'll keep looking and talk with the youngster to see if he can find it again.
Or see if you can get the Stoddard number then you can get the size perimeters and search that way.

That would be awesome, thank you. What do some guys do to repair the flyweel grooves? I would think build up the groove then machine it down, correct?

Is a 25hp flywheel the same as the 36hp? I found this in the gallery:

http://www.thesamba.com/vw/forum/album_page.php?pic_id=1168088

The part number listed there is SKF 99241 and you can see the size range on the box in the picture.

Here's a link to the dimensions for the 99241-

excuse my ignorance, but what exactly is a spedi sleeve?

60ragtop Tue Apr 08, 2014 6:43 pm

SKF Speedi-Sleeve

SKF Speedi-Sleeve This thin-walled sleeve [0,28 mm (0.011 in.)], developed by SKF, is simply pushed in position over the worn area, providing a counterface surface that is optimized for radial shaft seals.
There is no shaft disassembly or machining involved and costly downtime is minimized. Since the same sized seal as the original can be used, there is no need to search for other seals, or keep a stock of different sizes.
No special equipment is required since the installation tool is supplied with the sleeve. A mallet and a pair of pliers are all that is needed for the installation.
Features

The new generation SKF Speedi-Sleeve uses a proprietary stainless steel material and manufacturing process, resulting in an optimized seal counterface surface that minimizes wear on both sleeve and sealing lip. The proprietary material provides increased strength and excellent ductility properties of the sleeve. Imperceptible lubricant pockets enable the lubricant to reside on the sleeve and thereby prevent dry running of the sealing lip that otherwise can create excessive wear. The contact surface is wear resistant and machined to minimize directionality (0° ±0,05) with a finish of Ra 0,25 to 0,5 µm (10 to 20 µin.). This is, in fact, a better counterface surface than can often be achieved on a shaft.
SKF Speedi-Sleeve has a removable flange to simplify installation (fig 1). The flange can most often be left intact, but in applications where the flange will interfere with other system components, it should be removed so as not to cause friction heat and wear debris. The flange should also be removed in applications where it may reduce the supply of lubricant to the seal. This would reduce the cooling effect of the lubricant, resulting in elevated underlip temperatures and premature aging of the seal material.

Hello! Sorry for refloating such an old thread... I just got the same speedi-sleeve (99235) and have a question about it. How did you trim it dow after you installed it? it is much longer than the flywheel neck...

Thanks a lot and stay safe!
