Cam thrust plate options?

D9TE 528 with bronze plate:





D0VE 533 with CampCams bronze plate for Torrington bearing cam gear:





The standard (non-Torrington applicable) bronze plate ought to suffice.

I have been running the factory thrust plate.
I have a Crane roller cam. I was under the impression that the oil pump loading "pulled" the cam rearward?
Would this mean any camshaft with an aftermarket steel timing set should use the bronze thrust plate?

Cheers

So with a Solid flat tappet is a stock plate ok? or is the bronze plate better ? I have used the Ford Racing roller plate with a roller cam .
I have a spare roller plate i was going to use in another motor with the Solid cam but thinking twice now that the bronze or stock plate would be better .

Any harm or benefit using the Ford Racing roller thrust plate with a solid flat tappet cam ??? Seems the Bronze plate is good all round

Generally, the distributor gear is pulled downward and the camshaft is moved rearward. However, camshafts can sometimes move forward in some combinations due to other aspects of the design or setup of the engine, such as when there is no internal oil pump, etc.

In very general terms, the bronze plate is pretty much the no-brainer, one-size-fits-all option. But it's not a "must" in all cases.

The cam is pushed forward if you use offset lifters, this is a fact I learned the hard way. My c-headed 605 I used centered lifters for 2 seasons with a stock cam thrust plate with no wear at all to speak of. I had some trouble breaking snap rings on the intake rocker because of the side load. I thought I would try a set of offset lifters to try to straighten the push rod a bit to reduce side load. Ran the engine on the test stand for 5 min and pulled the plug and filter and the magnet on the plug had a mushroom of iron on it. After tear down I tried another stock thrust plate blaming myself for assembly error. Tried it again same thing happened, with only changing the lifters I studied it for awhile and noticed that the offset lifters are turned slightly in the bore under pressure, and tries to thread the cam forward. The reason I think I never heard of this before is because everyone I talked to about the issue never used a stock plate on a high end engine build , it was either a bronze plate or a roller style.

Yep, the off set cups in the lifter trys to rotate the lifter in the bore......loads the tie bar also.

anyone have the part number to the comp bronze plate. cant find it at comp or summit.

Lem sells them- http://www.460ford.com/forum/showthread.php?t=151456

That's not were any real friction is in the engine. Not my opinion....fact.

Ill stick to the roller bearing ones for roller cams, never a bearing in the pan,or a cam that failed of any kind ,but ive seen plenty of worn thrust plates

STEEL camshaft timing gears aren't usually compatible with a cast iron thrust plate just like steel camshafts aren't compatible with cast iron distributor gears.

On many occasions, I have surface hardened a production cast iron thrust plate and used a steel upper timing gear. Heat the plate until it is cherry red and drop it in a bucket of water. If a file cuts it afterward, the surface didn't get hardened.
Not the really correct thing to do but, it works in a pinch.

Just finalizing my parts . Using solid flat tappet cam, Roll master timing set that has a thin Bronze washer between the steel cam gear and cam thrust plate ...
Best cam thrust plate to use ?? Stock one ok or best to go the bronze one ? Happy to get bronze plate if required . Does having the thin bronze washer make a difference ? Guess it will run on either plate ? Thanks

I run the stock plates on iron or steel cams. As long as you are getting enough oil supply to the plate you won't have a problem. Plug the 1/4" hole in the #1 main area like the A-460 block does and it will direct more oil to the thrust plate, distributor gear, and shaft. Don't drill any holes in the top of the galley that oils the distributor shaft and gears. This just creates another leak.

I have a torrington plate that came with my Danny Bee that works well. I've not heard of any Danny Bee torrington failures.
