How do I install spindle adapter
 

I am putting a disk brake conversion on my straight axle. The kit came with inner spindle adapters. Instructions say it should slip on. Mine is too tight. I boiled it for a few minutes to heat it up and it still would not go on.

Do any of you have experience getting these things on? I would prefer not to remove the spindle...

I was thinking I would bake it in a oven at 300 degrees and try that????

Thanks in advance

get a wheel cylinder hone and make it fit.

Also check that area of the spindle for burrs or other banged up spots such as where a bearing race spun at one time. Over the years some of them get treated pretty rough.

If you have a digital caliper or access to one you can probably figure out where the problem is by measuring the spindle and the adapter.

Thanks for the input. I did end up putting the adapter in the oven at 350 in a small glass cookie pan for 50 minutes. This was just enough to give me about 15 seconds or so to fit it all the way back in the spindle. I just used kitchen hot pads to pick it up. It still cools off fast enough that you need to push it right up there...but you have a little time.

This worked great.

That makes me think of an experience that I had a long time ago. There is a ring on a VW Beetle crank shaft that is an interference fit like that. A very experienced VW mechanic told me to heat it up just hot enough so that a drop of spit on it would sizzle. I did it that way and it worked perfectly.
