Hi guys
I'm converting to a 4-speed and my crank is drilled to .88 but not reemed.
I understand the Dorman 690-025 is the bushing with .88 OD
I know I can have one made...but thought I'd ask first.
Thx

Mike
 
Napa used to sell them. Maybe still do. Dont remember the number though. I had an old guy make me some along with a driver. Their handy. U could also buy the bearing that fits in the torque converter register. Kim

Thanks for the reply...could not find a NAPA with .88 OD...I'm seen too many bad comments about the roller bearing.
If no one has the Dorman (one member said he had a batch...but didn't answer my PM) I'll take the std bushing to my local machine shop and have them turn it down. They take a while though....3-4 weeks typically.

Unfortunately those I knew have passed away or closed shop.
I rely on my one and only local machine shop...they do good work & are always busy.
If I have to wait 3 or 4 weeks so be it...was hoping someone had the Dorman laying around.
thx
 
I have a Napa Balkamp undersize that is .914 or so. I'm putting a 72 440 that was out of a New Yorker into my 67 Coronet with a 383 and a 4 speed and this was what I needed. I bought it years ago, and I know they are no longer available thru Napa. That .880 sounds pretty small. I saw on Ebay a while back that someone had the .914 bushings. Might want to check your OD of what you need.

I check it twice with a good gauge...it's .88 for sure . Dorman 690-025 was the right one (.885 OD)..and is obsolete.
I did see the .915 on E-bay...I have the .940 bushing, and will have it turned if no one has one at .885.
I just thought I'd ask ...save the trip to the machine shop.
thx guys

Why don't you get a modern one (Magnum) that fits the converter bore? By the way make damn sure the hole is deep enough. Been there done that
 
Yup, I've had good luck with the Magnum bearings too, as long as it's not a '67 and earlier 273 or slant 6. On those early cranks, I've had to run a hone in the end of the crank and then cut down a bushing for them. I used an adjustable reamer to chuck the bushing on, and then put it into my drill press to turn it. Some course sand paper was all it took to reduce the diameter enough to get it to fit into the crank. Don't cut it too much. You still want to have a slight interference fit so it doesn't spin in the crank hole. Of course, if you have the crank out of the block, you can always have a machine shop make the hole the correct diameter for a stock bushing.

Magnum bearing nice and easy fit.

Thanks for the suggestions guys.
The engine is in good shape (together)...not taking it apart.
The hole is plenty deep for the input shaft...just needs the bushing.
I've seen too many complaints about the roller bearing....but could be a bias on my part.
I believe the bushing is more forgiving, and is simply what I'm comfortable with.
 
I have these

If you dig deep enough there is/ was the big bore setup for a bushing instead of needle roller, and someone did a write up where they removed the roller and installed a bushing into the big bore boss. I don't remember how that OD came out............
