Bryan Posted December 15, 2021 Report Share Posted December 15, 2021 Is this the proper way to pull the hub off? From other posts I'm thinking you don't have to take the large center nut off. I didn't want to use a puller with 2 side bolts screwed into the hub. Was afraid they would strip. Already bent a grade 8 bolt in the center stuffed in the hole.

Sniper Posted December 15, 2021 Report Share Posted December 15, 2021 Yes, the bolt must come off, it is what holds the hub on. Quote Link to comment Share on other sites More sharing options...

kencombs Posted December 15, 2021 Report Share Posted December 15, 2021 Just screw a couple of bolts into the small holes and use a large screwdriver as a lever to hold the crank from turning. Resting the lever on the motor mount works. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted December 15, 2021 Report Share Posted December 15, 2021 you should invest in a hub puller or go to the parts house and pay the deposit, use their's and return if for full refund of your deposit....at minimum back the bolt off a couple turns to use it for getting it to break free and start moving, use a sacrificial steel plate to prevent damage to the bolt....then remove the bolt and use a socket or other suitable slug in the crank hole so to protect the threads... Pictured below is a universal harmonic balancer/hub puller... Quote Link to comment Share on other sites More sharing options...
Bryan Posted December 15, 2021 Author Report Share Posted December 15, 2021 Found a way to keep the engine from turning. Cardboard pad one top. Head back on. Bolt still won't budge. Heating, oiling, 36" breaker bar. Flexing the bar but don't want to break the bolt. Quote Link to comment Share on other sites More sharing options...

Pictured below is a universal harmonic balancer/hub puller... I have tools similar to that. What I have would work if I could get the center bolt to move. Glad I didn't keep pulling at the hub while the center bolt was in. Quote Link to comment Share on other sites More sharing options...
Bryan Posted December 15, 2021 Author Report Share Posted December 15, 2021 I had the washers already for use in a homemade pinion race seater. The exhaust pipe I already had laying around, just the right height. The center bolt does loosen CCW? Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted December 15, 2021 Report Share Posted December 15, 2021 these usually will break free with an impact gun....if nothing else, with the pulley off you are free to use a slug wrench Quote Link to comment Share on other sites More sharing options...

Use the right puller and a heavy impact driver, some heat with a torch might help. Edited December 15, 2021 by Sam Buchanan 1 Quote Link to comment Share on other sites More sharing options...

At this point I don't give a crap..What's another $50? Maybe I should go buy the magic $300 compressor and get the magic $100 impact wrench set so I can break the bolt off anyway.

Andydodge Posted December 15, 2021 Report Share Posted December 15, 2021 Bryan.........do you still have the crank pulley available?.........if so bolt it back on with just 2 bolts into the crank hub, then use a block of wood wedged between the pulley and the side of the chassis on the passenger side which will use the weight of the engine to lock the pulley and hence the hub and allow you to undo the centre bolt........from memory its 1 & 13/16th size........once the bolt is removed the puller you are using "should" work once you take the pelly back off...............I used this method on the crank hub/pulley when I removed the assembly in my 1941 Plymouth a few years ago.........but I would not be trying the cardboard thing on top of the piston.........as Sam mentioned a good way to bend a conrod..............regards from Oz.........andyd 1 Quote Link to comment Share on other sites More sharing options...

Yeah, thanks. Might try that some other day. Had a run of luck recently. Valve spring compressor from Ebay had been repaired by someone with weak side screw. He won't answer. That slowed me up. Probably can fix it but will take time. Now this..all afternoon. Quote Link to comment Share on other sites More sharing options...

Bryan Posted December 15, 2021 Author Report Share Posted December 15, 2021 It's not, everything is off. I might use the "damper back on" method and line up the small bolt heads so I can get the large socket on. I could put a lot more force on it with my 3 ft breaker bar, just afraid of breaking the bolt or something else. Had a lot of stuff breaking here lately. been heating it, tapping it, oiling it, etc. If the center bolt breaks what will it screw up? The hub or the crankshaft end?

Plymouthy Adams Posted December 15, 2021 Report Share Posted December 15, 2021 if it breaks it will remain in the threaded end of the crank....then it is a matter of extracting from there. At that time should it fail, you move forward with the hub removal. However that is a hefty bolt you working with. Quote Link to comment Share on other sites More sharing options...
Doug&Deb Posted December 15, 2021 Report Share Posted December 15, 2021 An impact gun may work. After a few shocks on mine it came loose with a breaker bar. Quote Link to comment Share on other sites More sharing options...
kencombs Posted December 15, 2021 Report Share Posted December 15, 2021 I can't imagine how difficult it would be to work on anything without an air compressor, grinders, air hammers, air drills and and impact wrenches. I've had mine for so long I've forgotten and never want to be reminded. 1 Quote Link to comment Share on other sites More sharing options...

Plymouthy Adams Posted December 16, 2021 Report Share Posted December 16, 2021 I could not go without an air compressor....While I could raise a car once on the lift.....I need air to unlock it for lowering. Even before this model lift, all my body tools and such are air powered. Quote Link to comment Share on other sites More sharing options...

Andydodge Posted December 16, 2021 Report Share Posted December 16, 2021 I'm not trying to have a "holier than thou" attitude but if you have the pulley.....reattach it to the crank hub with 2 of the bolts( 5/16 or 3/8th), wedge a block of wood between the pulley and frame and use the 3foot breaker bar you have on the socket and the centre bolt is undone, then unbolt the pulley from the hub and use the puller on the hub to remove it...........it may even be a little loose after the centre bolt is undone..............this centre bolt is about 1" in diameter with a fine UNF thread..........I would NOT expect the centre bolt to break...............andyd Quote Link to comment Share on other sites More sharing options...
