I believe the added height of the fingers were a design modification to overcome any potential centrifugal "lock out"/ "lock up", like experienced with the flat finger earlier models.

Normally hydrodynamic thrust bearings have a smooth surfaced rotating member some call the "collar". A fixed non rotating sector shaped disc pad (or pads if thrust is to be realized from both axial directions) is for the distribution of lubricant to the collar. I believe the oil distribution grooves were determined to be non essential due to the application. The oil distribution into the thrus

Good basic information from Mahle. But read the notation at the bottom of page 21 and the exception of clearance for turbocharged 2nd comp ring. Also read on how to file the rings, from outside-in.

I believe once you sand blast all the old (used oil, paint and gunk) off the NOS pan it is no longer a NOS item.

Thought this was a good article about torquing bolts/ nuts to spec. note that ARP was involved in the discussion. And there is an obvious typo about the Chrysler washer being allowed to spin while being torqued. The typo was corrected in the later script.

Finished with all my flywheel fixtures and looking for a few good riveted OEM non modified LM flywheels. Need about three or four to purchase for regrind and bolting with different bolt configurations. I have contracted the manufacture of high strength 12.9 bolts in 7mm, 5/16" and 8mm precision +.000-.001" diameters. I would prefer purchasing from the midwest to save shipping cost. If you have a

If all technical data for engine build is not available I would have to think twice. With an engine of this cost/ complexity there should be many pages of documented test results. Who did what to what should be preserved somewhere for reference. Flow bench results, bob weight calculations and results of final crank balance, etc. All internal component origins and specs. What valve seat material w

Ever since Shell oil technology group answered my question about the new T4 having over 1000PPM zinc with other advanced anti-wear additives and cost me a complete engine rebuild. I wouldn't touch any of the Shell products out of principal only. They may have some good oil but I'm not going to test their oils for them.

I shot over some of your heads means my explanation of the what and why was inadequate in detail. Not that you couldn't understand what I am doing. When I rebuild a flywheel assembly the ability of the pressure plate to perform properly is a critical. The only way to confirm clamping force is to measure it. I do not believe the clamping forces are as great as some believe. Also if the pressure

I guess I shot over some of your heads. I built a load cell based, hydraulically driven test machine to test the forces required to disengage pressure plates from clutch plates. The machine will (when finished) provide a graph showing how much force is required over what travel distance until a nominal thickness clutch plate is released. My initial test were conducted on a 1800# and a 1500# Cl

While I'm setting up my shop to put Snowball back together (correctly). I've been evaluting my flywheel/ pressure plate testing machine. I built this machine so as to confirm pressure plate force against the clutch plate. Also how much travel the pressure plate will be pushed in before release of clutch plate and if there are any uneven movement. I never thought about the advertised pressure plat

Yes there were some assumptions thrown into the calculation for pressure drop. I used the 6 gpm @ 4400 engine rpm. Obviously because the gear pump is a positive displacement device the flow is pretty much linear. Many GM engineers were used for the corvair project and the sum total of their knowledge would fill truckload information. What I'm attempting to do is look for obvious areas of concern

Although I wasn't able to show in the pics exactly how much the oil cooler brackets are problematic, you will be able to see the actual seals as they would be when installed in your engine. Some brackets are better than others with respect to their porting locations but I haven't found any without an off center condition. The off center condition is one that can create additional pressure drop

Anytime you can help pull heat out of the oil it's a good thing. I'd be interested in seeing how you tapped into the flow circuit. I am assuming you replaced the 12 plate cooler with the cooler with the fans. What one has to be aware of is introducing additional pressure drop when you are pulling oil out of the discharge port from the pump. The pressure drop or loss of pressure is unavoidable

Remove the quick shift kit and things will get much better. It's a problem many run into when trying to use the quick shift mechanism. Due to increased length of shifter ball the resulting problems are magnified from the other end.

Sorry for the delay in commenting back on the subject. The base question I presented was to inquire about the manual transmission flex plate(s). I just returned a "NOS" one with one of the the crankshaft bolt hole showing signs of stress cracking. My reasoning for the inquiry is that the flexplate take a real beating and cyclic fatigue can cause fractures around stress gradients. The one I purcha

I've been looking at the flexplates on LM's, not sure if they are the same on EM's but they look like they should take a beating. Not too many comments on failures but can't imagine they survive as well as they seemingly do. It takes a special metal forming process that I believe I have identified. I have one special metal worker here in central Indiana that believes he could reproduce the bla
