289 crankshaft bushing
 
If anyone can help on this ... it will be greatly appreciated . A friend of mine bought a 289 for his street rod and needs the part number for the bushing/bearing that goes in the end of the crank that the transmission shaft rides in . All my info is for FE engines .

Thanks !

They are readily available at Kragens, Pep Boys, or any parts house. An upgrade that can also be utilized it the roller bearing used in the crank odf a 5.0 Mustang with manual trans.

If you choose to run a needle roller bearing as an upgrade to the OEM bushing I feel it must be checked for proper alignment. The old bronze / oil-lite material does not seem to be affected if slight machine tolerances or ?? exist. On the other hand the bearing type bushings insist everything is right.

Not to say cutting corners or not checking things is acceptable. I am saying an oil-lite bushing is more forgiving and other than just worn out I have never seen them cause a failure. I run them in my alky funny car with a JP1 engine over a needle bearing. Lots of ways to skin a cat, whatever works for you.

Jeff ... I understand what you`re saying ... and agree . I run the bronze bushing in my 427 Galaxie , but have a roller bearing in my Cobra . So far , both are fine .... however , the one in the Galaxie is going on almost 8 years and the Cobra one about 6 months . Maybe someone else can expand on something . I was told somewhere along the line that Tremec preferred the roller bearing over the oil lite bushing as it would keep the transmission shaft in position better as time went on ??

Bob,
When somebody tells me their roller bearing set up is 8 years old I will be a happy camper. Jeff C

Mine roller bearing (5.0 type) has been in since 1990. I am not a high mileage driver bit it has been maintenance free up to this point. I run a T10 4 speed transmission and 289. I have also seen a double shielded ball bearing used.

I put the bearing in my 289. Have 25,000 miles on it so far no problems.

I've had a roller type in my Mustang for 7 years, and never worried about it...'till now. I have a T5 with an OEM type bellhousing. I've never had allignment issues with this set up, but I constantly hear of issues with aftermarket bellhousing. I wonder if that has some impact.

zrayr 07-21-2009 06:51 AM
not quite on topic, but I've never understood why the after-market bell housings don't fit as easily as the Ford units?

My guess is that they are probably pressed formed with no post operation to true them up. Any machine work may weaken them due to the realitively thin wall thickness. Obviously they still have an advantage over cast aluminum in stopping an exploding flywheel, but have their trade offs too.

I'm interested to see if those who have had trouble with needle bearings were running stock bellhousings or aftermarket.
