MarcDeSoto Posted April 7, 2023 Report Share Posted April 7, 2023 (edited) I have an oil leak, a bad one, under my chaincase cover. So I removed the radiator, fan, vibration damper, etc. I think I will need to replace the chaincase cover gasket and maybe the oil pan gasket also. Do I have to remove the crankshaft nut to do this? What's the best way to remove it. I have the socket and wrench. A friend told me to put the wrench on the nut and jam the breaker bar on the frame. Then, hit the starter button which turns clockwise. The breaker bar will not let the nut turn with the starter, and might break it loose. Is this a good idea?

kencombs Posted April 8, 2023 Report Share Posted April 8, 2023 Depends, do you have an impact wrench? If so, that is the answer. Otherwise I prefer a box end wrench and 3-4lb hammer to loosen. Always afraid the breaker bar would somehow rotate and damage something. Quote Link to comment Share on other sites More sharing options...
JBNeal Posted April 8, 2023 Report Share Posted April 8, 2023 A much slower approach is to use that breaker bar but instead of using the starter, put a prybar on the flywheel ring gear. Quote Link to comment Share on other sites More sharing options...
9 foot box Posted April 8, 2023 Report Share Posted April 8, 2023 Maybe the chain cover was tightened before the hub was put on forty years ago. You might be able to replace the seal and center the case with your hub, and possibly a speedy-sleeve if your hub is worn. You might need a 1 11/16” socket and a short piece of pipe in the end of the crankshaft so your hub puller has something to push off of. I’ve bought larger sockets from Tractor Supply for $20. You will need a 3/4” to 1/2” adapter for the tools you probably own. Quote Link to comment Share on other sites More sharing options...
MarcDeSoto Posted April 8, 2023 Author Report Share Posted April 8, 2023 I wish I had that tool C-522 for centering the chain case cover. I was able to break the crankshaft bolt by placing the 13/16" socket in place and bracing the breaker bar against the frame. Then cranking the starter. The socket would explode off the bolt when I cranked, so I placed a drift in a hole on top of the frame to hold the socket in place. Then a couple hits of the starter broke it loose. I ordered a new oil pan gasket and chain case cover gasket. but I will need a new seal too. I've forgotten what that looks like or how to install it. I wonder if it can be ordered alone?

Sniper Posted April 8, 2023 Report Share Posted April 8, 2023 Yes, the seal can be ordered separately, I would suggest a speedi sleeve as well Quote Link to comment Share on other sites More sharing options...
Hickory Posted April 8, 2023 Report Share Posted April 8, 2023 Speedy sleeve seals are usually a different inner diameter so make sure you get a seal for the sleeve. At least this is true in the diesel world. I've never bought one for these cars. Quote Link to comment Share on other sites More sharing options...
Sniper Posted April 8, 2023 Report Share Posted April 8, 2023 You can still use the stock seal. 2 Quote Link to comment Share on other sites More sharing options...
MarcDeSoto Posted April 8, 2023 Author Report Share Posted April 8, 2023 Yes, the stock seal comes with the timing cover gaskets. I'm buying Fel-Pro gaskets from Rock Auto. Quote Link to comment Share on other sites More sharing options...
The Oil Soup Posted April 10, 2023 Report Share Posted April 10, 2023 Tool C-522 is not needed, install the cover with a couple bolts to loosely hold it in place, mount the pulley/hub to center the cover then tighten the bolts. Don’t forget to install the “felt” donut/dust seal between the cover and the pulley. 2 Quote Link to comment Share on other sites More sharing options...
Sniper Posted April 10, 2023 Report Share Posted April 10, 2023 You did not mention is your hub has a groove worn in it where the seal rides, if it does it will leak. A Speedi Sleeve with repair that. Quote Link to comment Share on other sites More sharing options...
MarcDeSoto Posted April 11, 2023 Author Report Share Posted April 11, 2023 Yes, it does look like I have groove in the hub from wear. Where do I get a Speedi Sleeve and does it replace the seal that comes with the timing cover gasket kit? I wonder if I could just buy a new hub?

Sniper Posted April 11, 2023 Report Share Posted April 11, 2023 Yeah, that's a groove alright. Go watch the video I linked earlier in this thread. It will show you what a speedi sleeve is and how to install one. It does NOT replace the seal, all it does is provide a smooth surface for the seal to ride on. As for what speedi sleeve to get, if I navigated SKF's site (no Desoto listings so I used a 48 Chrysler) this is the one, same as my 51 Plymouth. https://vehicleaftermarket.skf.com/us/en/products/99218 Punching that number into Rock Auto shows three brands available. https://www.rockauto.com/en/partsearch/?pgname=Engine&partnum=99218 1 Quote Link to comment Share on other sites More sharing options...
MarcDeSoto Posted April 11, 2023 Author Report Share Posted April 11, 2023 I looked for new hubs and couldn't find any. So it looks like I need one of those sleeves. Do you think O'Reillys would have them to order? Quote Link to comment Share on other sites More sharing options...
Sam Buchanan Posted April 11, 2023 Report Share Posted April 11, 2023 The pitiful-looking hub on my 218 (no, that isn't a crack, just surface corrosion): Installing the Speedi-Sleeve: Good to go. 1 Quote Link to comment Share on other sites More sharing options...
MarcDeSoto Posted April 11, 2023 Author Report Share Posted April 11, 2023 Wow, looks beautiful! My shop manual advised me to just order a new hub. Guess you can't do that anymore! Sniper, thanks again for telling me about the Speedi-Sleeve! I went on Amazon and orderd the National brand Redi-sleeve. I lucked out because they were offering free Prime for a month, so I'm getting the part on Wednesday! 1 Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted April 11, 2023 Report Share Posted April 11, 2023 Don't get any paint on that new seal surface...the new seal won't like paint. 1 Quote Link to comment Share on other sites More sharing options...
Sniper Posted April 12, 2023 Report Share Posted April 12, 2023 I really have to question the competency of the shop that did that rebuild. Using that hub was a guaranteed leak and they let it out the door that way. Speedi Sleeves have been around for decades, Vintage Powerwagons sells NOS hubs.

MarcDeSoto Posted April 13, 2023 Author Report Share Posted April 13, 2023 I'm the shop that did that rebuild 40 years ago. I guess I was incompetent. I just put the new redi-sleeve on and for once something went on perfectly! 1 Quote Link to comment Share on other sites More sharing options...

James_Douglas Posted April 14, 2023 Report Share Posted April 14, 2023 I would by a new hub. Then take the old one to a machine shop and ask then to turn it down a few thousands and also to turn the inside a very little bit so it will slide nice onto the crankshaft without the key. Then use that hub as 'the tool" to center the cover. That is what I did. Works fine. James 1 Quote Link to comment Share on other sites More sharing options...
MarcDeSoto Posted April 15, 2023 Author Report Share Posted April 15, 2023 Where do you buy a new hub? Do they still make them? Quote Link to comment Share on other sites More sharing options...
Sam Buchanan Posted April 15, 2023 Report Share Posted April 15, 2023 Sniper gave you a link for NOS hubs five posts ago…….sigh……… But you don’t need a new hub if you installed a speedi-sleeve. 1 Quote Link to comment Share on other sites More sharing options...
