Jerry Roberts Posted January 31 Report Posted January 31 I had my engine rebuilt 11 years ago . It has had a leaking front main seal that has recently gotten worse . The engine is from a 1939 Dodge car . When I pulled off the timing chain cover , the speedy sleeve came off too . The speedi-sleeve has cracks . I have ordered a new front main seal and when the new seal gets here I will test fit it on the flange/hub that fits on the crankshaft and into the timing cover . To my untrained eye the flange/hub has a slight groove worn into it from the seal but I will see how well the new seal fits . I can't find the proper name and part number for this flange/hub it anyone has this information . Quote
Sam Buchanan Posted January 31 Report Posted January 31 I think I would prefer a new SpeediSleeve over putting a new seal on a worn hub. Be sure the sleeve is secured to the hub with sealant so it can't spin on the hub. Quote
Ivan_B Posted January 31 Report Posted January 31 (edited) What's a Speedi sleeve? A jacket you put on a worn hub to use with oversized seal? That groove is too much. If you can see it with your eyes, the seal will not seal properly... ? The proper way to fix that is to get a new hub or machine the existing one (proper sleeve or metal coating).

The Speedi-Sleeve is shown in the photos , it is a very thin steel band that is pressed over the sealing area . You would use it with the standard seal . If I can find the part name and part number for the hub , i would price a new one . If obtainable . Quote

Speedi-Sleeves (proprietary brand name) are a common and widely accepted repair in the automotive and commercial communities. They have been around for a long and are available to fit nearly any size sealing surface. https://www.skf.com/us/products/industrial-seals/power-transmission-seals/wear-sleeves/skf-speedi-sleeve Your education is proceeding at a break-neck pace....first solder sleeves and now speedi-sleeves! ? 1 Quote

You are right... ? I wonder what the seal manufacturers think of these, though, because I cannot image the sleeve being so thin that it actually fits within the seal seating clearance specified by the OEM. Quote
Sniper Posted January 31 Report Posted January 31 Well SKF makes the Speedi sleeves and they also make seals so I think the answer is there 1 Quote
oldodge41 Posted February 1 Report Posted February 1 I think Vintage Power Wagons calls it a Crankshaft Pulley Hub. Check with them for availability on your application. Quote

I would probably expect a different seal for the sleeve application... But then, again, I've never even heard of these in the first place. Quote
rallyace Posted February 1 Report Posted February 1 We used only SKF speedy sleeves at work to repair worn shafts at the seal contact points. Make sure that the shaft is clean of all traces of oil or grease. We always used a bearing sealant when we installed them. Follow the instructions that come with the speedy sleeve and you should not have any issues. Quote

But then, again, I've never even heard of these in the first place. Uses the same seal, the sleeve is only a very few thou's thick. This is not untested tech, these things are an accepted repair. I'm running one on the crank hub of my P15. Quote
Jerry Roberts Posted February 1 Author Report Posted February 1 Farmer Jon posted a link to one of the hubs on ebay , and with that listing part number , I was able to read other descriptions on other listings for more information . So I bought a new hub . Thanks guys . Quote

Ivan_B Posted February 1 Report Posted February 1 Is that actually a crack? To me it looks like some kind of weird corrosion edge ? Quote

We discussed this extensively when I first posted this photo 3+ years ago. It isn't a fatigue crack, it is corrosion and is only on the surface. Yes, that is a worn hub and not that unusual for a bearing surface eroded by dust and a leather seal. But the Speedi-Sleeve is a good remedy. I filled the groove and "crack" with JB Weld prior to installing the sleeve. Quote
RobertKB Posted February 1 Report Posted February 1 The machinist I have had do some work on my cars has absolutely no time for speedi-sleeves. Says they are way too thin but may be ok for vehicles that get low miles but not daily runners. He wouldn’t put a Speedi-sleeve on the same hub as shown above. He machined the hub and made his own thicker sleeve to bring it back to original specs. Very reasonable on price as he likes working on old car stuff. I’m lucky although I think he has retired now. He had his own business for years but sold out to a big outfit and ran their shop. He did small jobs like mine on his own time. He’s a real character and very proud of his trade! 2 Quote
Ivan_B Posted February 1 Report Posted February 1 I like some parts that have sleeves\inserts from the factory. This way you can pull the old one out and just use a new one. Back to specs ? Quote

I think you just explained why it is not practical to get the machine work you described in most instances today. Machining in a commercial shop is expensive even if you can get someone to do this small a job. You had this done some time in the past by someone who enjoyed doing this on his own time. That doesn't represent reality for most of us now. This is a similar situation to the solder sleeves we discussed recently. Both of these technologies are proven and readily accepted in a variety of applications. However, some folks are hesitant to use technology with which they aren't familiar so they are convinced it is unsatisfactory. Fine......don't use it. The rest of us will take advantage of modern tech which is usually less expensive, doesn't require old-school techniques or expertise and yields satisfactory results. Personal choice. By the way....my P15 has disc brakes, an alternator and a full-time electric fuel pump.......I don't hesitate to drive the car anytime, anywhere and it has proven to be extremely reliable. Old tech or new tech? ? Edited February 1 by Sam Buchanan 2 Quote
harmony Posted February 2 Report Posted February 2 I personally think that the key to speedi (redi) sleeves application, is taking a precise reading of the shaft that it will be fitted over. That can be difficult if there are a few worn sections of the shaft. If there are significant groves in the shaft or if it feels like the sleeve is going on to easily, I suggest using loctite 609 to make sure that the sleeve that was selected, doesn't rotate. 1 Quote
