Is the torque converter flush with the flywheel?
The torque converter was full seated when I bolted the transmission to the engine (I could barely get the very tip of a finger between the converter the transmission case). To move the converter forward and flush with the flywheel, I turned the converter to bring it forward.
How big are the bolts on a torque converter?
The transmission to engine bolts need to be at least about 50 ft/lbs as these are the same size as the head bolts, but a slghtly lower grade bolt. (head bolts are 70-80 ft/lbs) Id think the converter nuts could go to about 45 ft/lbs, being a 3/8″ NF thread. The stock converter to flex-plate bolts are 5/16 NF and the spec is 25 foot pounds.
How big is a flex plate converter nut?
The stock converter to flex-plate bolts are 5/16 NF and the spec is 25 foot pounds. The bell to engine bolts are 7/16″ NC grade 5 and the recommended torque is 45 foot pounds. I’ve never seen converter nuts that were 5/16″NF. Every one I’ve seen on a Ford were 3/8NF (You must log in or sign up to reply here.)
When do you pull forward a torque converter?
Typically it will need to come forward about 1/4-3/8″. If it had been flush with or tight against the flexplate before you bolted them together that would indicate the splines weren’t fully engaged on the input shaft. You done good. Carry on. Agreed. It’s actually GOOD that it had to be pulled forward slightly.
How does a torque converter work on a flywheel?
To move the converter forward and flush with the flywheel, I turned the converter to bring it forward. Did I screw up in how I unseated the converter and brought it forward to the flywheel for the bolts to be inserted?
How big is the flexplate for a torque converter?
Verify that the torque converter mounting pads sit flush against the flexplate. When installing 7/16” bolts to attach the torque converter to the flexplate we recommend that you first enlarge the torque converter bolt holes in the flexplate to an inside diameter of 29/64” (.453”).
How to check the torque converter bolt pattern?
Verify that the torque converter bolt pattern matches the flexplate bolt pattern. Verify that the flexplate bolts do not interfere with the torque converter. Verify that the torque converter mounting pads sit flush against the flexplate.
How to check a torque converter for reliability?
Verify that the torque converter pilot diameter matches the crankshaft pilot diameter. Verify that the torque converter bolt pattern matches the flexplate bolt pattern. Verify that the flexplate bolts do not interfere with the torque converter. Verify that the torque converter mounting pads sit flush against the flexplate.
The torque converter was full seated when I bolted the transmission to the engine (I could barely get the very tip of a finger between the converter the transmission case). To move the converter forward and flush with the flywheel, I turned the converter to bring it forward.
Can a torque converter free wheel during trans installation?
NO RAGRETS!!! No, The converter has to be fully seated in the transmission pump and it has to line up with the flexplate during installation. The converter will not free wheel once the trans is installed. The best way to line it up as by index marks on the block and trans case.
How does a torque converter work with an engine?
Transmission and converter should mate with engine, crankshaft, and flywheel with relative ease. Face of transmission flange must be flush with engine all the way around before any bolts are tightened. NEVER use bolts to ‘draw up’ transmission to case.
Can a torque converter line up with the flexplate?
No, The converter has to be fully seated in the transmission pump and it has to line up with the flexplate during installation. The converter will not free wheel once the trans is installed. The best way to line it up as by index marks on the block and trans case. It will get you close enough.
