40 ford front axle
I need to remove the spring perches from the front axle. I have read on the net about heating the front axle and don't heat the axle. I have heated it with a propane torch and melted candle wax in the nut cavity.
I saw the home made puller for pulling the perches but it won't work on a 40 axle. I know this is an open question but I need advice before I proceed further. |

Re: 40 ford front axle
Put the nut on the threads a couple turns. Heat the axle up with a decent torch and drive the pin out with a punch and a big hammer. The nut will keep from mushrooming the end. Or use a good air hammer. When you put it back together clean everything and chase the threads. Use neversieze so its easier for the next guy to get it apart

Re: 40 ford front axle
using a press is the only civilized way to not wreck stuff. some are very uncooperative.

Re: 40 ford front axle
I haven't run into one I wasn't able to remove with my 25 ton press, and have never ruined anything. Most I have removed have let go at about 17 tons.

Re: 40 ford front axle
The snapon press is a fixture that clamps around the axle with a screw to push the pin out. A common hydraulic shop press has one down fall. It's awkward if your by yourself.

Re: 40 ford front axle
I totally agree. Trying to press these pins out of an axle/wishbone assembly in my 40 ton hydraulic press, while working alone, turned out to be an exercises in futilely for me. After getting the assemly properly setup and supported in the press, with liberal amounts of Kroil applied over a period of several days, then heated with a torch, I wound up bending the axle and was never able to remove these pins by this method.

Re: 40 ford front axle
I understand not everyone has a bridge crane and overhead lift capabilities. I almost always work by myself. I would think a hydraulic version of the Snap-On tool would be ideal.

Re: 40 ford front axle
I machined a piece of a cylinder rod and threaded it for the perch. I will place a piece of hardened rod inside so the pressure will be on the perch and not only on the threads when tightened down.
