changing pilot bushing

[dmcclure]

I've changed many pilot bushings in the past, pack it full of grease, wooden dowel trick, but I dont see that working on my 47 Special Deluxe. Who knows of a trick or tool to help me achieve this.

What keeps it from working?  I have always done mine that way.  Is it a bushing or a ball or needle bearing?  They make a pilot bearing  puller, that goes into the bearing then a wedge spreads the fingers apart so that the hooks on the fingers open behind the bearing and hook on the lip.  The rest of the puller bridges the opening and pulls the fingers out as you tighten the bolt.  If it is a needle bearing then you can collapse the inner race and use a drimel grinder to cut through the outer race housing.

It is a bushing. It feels like there is just a small crevice about an inch and a quarter back in there, then there is another inch or so to the bottom of the hole. Its like the bushing has no backside for the grease to push against. Thank you for the reply!

DMCCLUE:  I have the special miller tool that removes the pilot bushing and then the miller tool that is used to install it into the flywheel and then burnish the pilot bushing so it will be perfect fit.  No use in messing with non factory tools. Use the factory tool to do it right and easy.

I used my air chisel and split it in half.  Spend some time cleaning out the bore real good if you do it that way. After you install a new bushing, check the fit with an input shaft or fit the trans to the bell housing.  Should go in nice and easy.  I had to use a wheel cyl hone to get enough clearance for the trans to bolt up.

If all of you read my post I have the two miller factory Mopar tools to remove the pilot bushing and also the tool to insert it into the flywheel and also the tool that makes is perfectly round, it burnishes the bearing to the correct size so the input shaft fits the pilot bushing correctly.

 

Stop using makeshift tools and use the correct tools. When using the correct tools it will take you no more than 15 to 20 minutes at max to do the complete job of removal and inserting and burnishing the bearing.

I have used a tap to thread the inside of the bushing, then ran a bolt through to pull it out. 50 years working as

mechanic at dealerships both auto and heavy truck and they never had a 'tool' to pull a bushing like that. replaced mine recently and the bushing is very thin, I used an awl to collapse the bushing, pulled the old one out and used a bushing installer to put the new one in, then load up the cavity with high temp grease for lubrication. this was on my 48 Plymouth.

Most pilot bushings are made from oilite bronze. They should be soaked in oil prior to installing and no grease should be used as it clogs the pores and leads to premature failure.

I do this kinda work every day and have the correct tools to R&R the bushings/bearings in the end of the crankshafts.

The bearing is an "oilite" bushing and as Don says-soak it in light weight oil-no grease!

They can be removed although much slower and more difficult by other ways.

I have used the grease and dowel, never had a hollow crankshaft, there is a bottom to the hole somewhere. Either send for the loaner tools offered or pack that bitch with grease, put the goggles on, insert tight fitting dowel and whackamole!

[Dodgeb4ya]

^^^^^Been mentioned here many times-it works. Pack the hole as tight and air pocket free with grease as you can. Use a very precise fitting rod or dowel and have at it.

Rich; Maybe they didn't realize you were offering to "loan" your tools to them ??? Not many that kind these days !!!  Cass, alias littlemo...

As stated in a previous posting I have the two Miller factory tools that the dealerships used to remove the pilot bushing and also install the pilot bushing and it also burnishes the bushing to the correct size.  I will loan out the tools but will require a deposit.  So if you are going to do the job use the factory tools. A friend of mine used the tools ona 40 Dodge and I have a power point presnetation on how the tools are used. 

Here are pictures of the two tools being used

Wish I had known about your tools before I changed my clutch several years ago. I used a regular Pilot bushing puller. Was a tough job, but it did come out. Soaked the new bushing in oil as suggested for several days. Then installed it using a socket and an extension. No issues since. Guess I was lucky.
