J.J. do you suggest dry or lubed on Slotted Hex.Nut when reinstalled ..

I think lubed will sometimes give you a false torque, so I recommend dry.

I think JJ has it right.

If you are torque setting a nut, it is usually just clean, dry threads. Lubricating torqued fasteners is not usually recommended, but some times such as with aluminum or stainless steel, some lubricant may be required to keep from galling or welding the bolt to the assembly.
I know of some specialized bolts (on more than a few modern engines) that are tighten to N-turns past finger tight that permanently elongate the bolt. Those bolts are use once and toss. There were (are?) some disk brake assemblies that are torque to a setting and then 1.25 turns beyond. Again, those tend to be use once and toss. As far as I know, only the Deutz engines in the PTs have unusual torque settings (Torque in order, then tighten by a given angle). (See Foley engines for some details as an example.)

All the best,

Peter

OK have my tires mounted .. Didn't have a lot of time but did put some heat on the center of the hub and attached a wheel puller. So far will not come off. Thinking I may need a better wheel puller the one I have the jaws are to thick it does not get a real good grip and slips off.

How long are you guys applying heat to this hub and are you heating behind the shaft or just in front of the shaft and around the middle.

the factor puts lock tight on the tapered shafts and says thghten tight. I have pulled as least two of these hubs and tightened the a very heavy duty puller i made that uses the lugs bolts to hold it in place then hit with a large hammer. Got the hub off but stripped the threads. had to make another nut.

Very nice... I was also thinking of a way to use the hub threads with a puller.. Worried I might some how strip them .. Wondering if the hub might get out of round with to much pressure...

You probably want to add some Kroil,PB Powerblaster frozen bolt remover, or LiquidWrench. I would warm it up, add the rust buster, and come back in a day.

I wouldn't try to do it on heat and force alone. I think that the downside to being old and not heavily used is that your hub is going to be really stuck on. Anyone using it heavily would have occasionally hit something to fracture the rust/work dust into the area.

Good luck!

All the best,

Peter

Yes I did coat it with PB Powerblaster... :thumbsup:

Meanwhile the garage door stopped working and I have to fix that first, then get back on the PT.. I've been over loaded with work a good thing for my business.. I just bought a better wheel puller so now just waiting on the weekend and some free time..

Hopefully somehow the PB will wick it's way into the shaft area and help break up some of the rust etc..

Thanks for the help Peter everyone...
