Erndog Posted May 21 Share Posted May 21 (edited) I need to remove the rear wheels of my 1930 Model 61. I am by no means new to the process, but have never had such a difficult time of it! I have tried many methods over the last 18 months or so, to no avail. Not having a Buick original hub puller, I had to resort to a three legged puller, which was less than satisfactory. I did the usual application of a lot of tension, followed by many hefty raps on the end of the puller screw with a sledge hammer. This was done both cold and with heat. Unfortunately, I do not have access to an oxy-acetylene setup, so I had to resort to a lot of MAP gas application. I decided to have a machine shop build me an original style puller that screws onto the hubcap threads. After a long time of thread measurements, thread depth measurements, thinking, etc, the machinist's opinion was that the risk of stripping the threads was too great to risk, considering how difficult the process had already been. We opted to make the puller in the attached photo. It is comprised of very good steel and appears to be a good design. However, the results are still the same. I figured maybe the wheel I was trying just had it's own issues, so I moved to the opposite wheel. Exactly the same results. For the record, no, the emergency brake is not applied, and yes, the nut is backed off, but on enough to protect the axle threads. I have tried spraying Kroil and Liquid Wrench up into the shaft area, but as completely expected, no effect. The taper on the shaft is very slight and being nearly 100 years old doesn't help. Am I overlooking something or doing something wrong??? Is it just a matter of not enough applied heat? I don't want to do any damage to anything and I feel I have approached the dangerous end of applied pressure. Any advice? I know this is not the first case like this.
