Also on the same subject; for a few years the Minispares pump ports almost overlapped the cam journal bore; such that you had literally the width of the gasket of gasket land. I always got lucky, but a few didn't. 

All of the above.  Try another cam, see if you get the same readings.  If the second cam is OK, the first cam has (OK, might have) a problem.  Otherwise, I would guess the triangle plate is not sitting down all the way, see if the bolts are bottoming.

There have also been recent 1275 oil pumps with little or no chamfer on the corner of the body. When fitted, they bottom in the radiused corner of the block recess and don't seal on the gasket.

Cure if needed- grind, file or sand a 1/16" chamfer on the pump before fitting.

I should correct myself. The pump should not be a part of the end float. I have also received pumps that require shortening the tab. When building an engine assume nothing check and recheck everything. Steve (CTR)

There was also a batch of oil pumps that were made slightly thinner than stock and the bolts bottom out before the pump is fully seated.

I saw a batch of duplex cam sprockets imported to Sydney a couple of years back that had the step width machined too wide. Couldn't fix it without upsetting the chain alignment, so they got binned. Maybe more of em got away from the makers....

Always check the end float with the oil pump installed - there has been more than a few pumps enter the system with an incorrectly mahined spade.  

I'm at work and can't post the pictures (which are on my HDD at home), but the short version is that the spade is too tall and binds the cam against the triangle, resulting in premature wear to everything and often a loss of oil pressure if the pump cant seat/seal properly. 

The pump and the triangle on their own aren't enough components to check the end float - you do need the cam sprocket as well.

.048" without the sprocket would suggest to me that the oil pump isn't a dodgy one though.

On the back side of camshaft gear there is a step the thickness of this step, subtract the thickness of triangle plate and that is your cam end float. Oil pump has nothing to do with it. Steve (CTR) 

You did re-fit the cam sprocket didn't you?  You cannot measure the cam endfloat without the sprocket in place and its nut tightened.  

Hello:
I am assembling a rebuilt 1098 and have discovered that camshaft end float is 0.048" which I believe is about 10 times what is acceptable.  The engine was rebuilt due to a spun main bearing.  I did not check cam end float when disassembling.  The 0.048 measurement is with a new cam retaining plate and new oil pump.  The old plate has minimal wear and I fitted the old oil pump and still had 0.048".  I retained the same pre-rebuild slot-drive camshaft (marked "256").  The cam shows no real wear on the end surface.

Am I missing something?  Is the cam junk?

Thanks in advance.
