Ok gotcha. I didn't realize that there were different diameter snout sizes on these. This is a 1990 block and crank. So I need to find a proper size torque converter or how do I remove the pilot bearing from the crank?
Okay hold up a second here hold up a second. It's all starting to make sense now this engine came out of a truck with a manual transmission so that bushing is for a manual transmission so I'll have to do is remove it correct the brain is starting to work thanks guys!
Yes BUT what I said still holds. I think it was late 60s early 70s but don't quote me
Yep I measured the hole that the bearing is in and the TC about should fit in there. I just gotta get the darn thing out. I tried grease and rags wadded up, no luck so far
Tried the slide hammer with blind bearing attachment. No dice, couldn't catch the lip of the bearing. I swear it's less than 1/32 gap between the bearing and the back of the crank. I will try the screw method later during the week.
That is only a problem on the 273 engines. The register is smaller on the 273 crank, and the corresponding torque converter about is smaller. And the trans for the 273 has a different spline count on the input shaft than the later 318/340/360
I tried several types but I probably gave up to early. It looks as though there's a small step down between the bushing diameter and the crank end diameter. So if I use a drift that will fit into the crank end the grease just pushes past the bushing, and if I use a drift that is snug in the bushing it bottoms out when it hits the crank lip diameter.
fill the bushing right to the 'front' with grease, get your drift that's snug in it and whack it hard with a decent hammer. it'll take a few goes refilling with grease and repeating but it will come out.
i find greese and bread works the best for me .
As 66fs mentioned, it was the change made from a '67 273 forged crank to a '68 cast one. The transmission made the same change internally that year....across the board to all 904's and 727's both small block and big block versions. The slant 6 engine also made the same crank register diameter change the same year. All 318, 340, and 360's had the same large crank register. Manual transmission cranks received a final machining for a manual trans pilot bushing, but, most automatic applications didn't get that machine work.
So the OP MIGHT need a sleeve in his crank to makeup the machined difference between manual and automatic crank?
What about using a Tap (of the correct size) to cut into the bushing and then slide hammer it out? (kind of like how to remove the bushing in the Lower control arm)
then there is this...When all else fails maybe drill & tap a couple 5/16-18s for a puller......
Wow this thing looks promising! Ever tried it?
No, it looks to be a 360 converter. That will fit all V8' except the forged crank 273. He just needs to remove that pilot bushing.
