Megane Oil Pump Upgrade - crank clearance

[Struggler]

I mentioned this in another thread but it didn't get anything back so its getting its own thread.

I have installed the uprated oil pump kit from PMS as part of my bottom end rebuild. The clearance to the crank is quite concerning to be honest, got about a gnats pube worth of clearance to the crankshaft. I know I have an early ph1 that appears to have a different crank in it from the fact I don't have a keyway where the cam pulley goes, not sure if its different in other areas too.

Has anyone else done this conversion and can confirm that this clearance is OK?

Give Nick a call at PMS and express your concerns.
He’ll be able to help.

With end float removed and crank pushed all the way towards the pump can you get a feeler gauge in there?

 

[Struggler]

How does one "remove the end float"?

Id say there is about 3-5mm between the pump and crank at this so unless the float is going to take away nearly all of that then I would say a feeler gauge will fit.

 

[Flob]

You just tap the end of crank so all the end float is on one side. Same way you measure end float.

But don't bother, 3-5mm is miles inside an engine. If you can be sure the clearance is that then you're done.

will give it a little tap when I make my final assembly. I assume its just a little tap on the flywheel end.

I'll be honest also, i did contact Nick from PMS already and he said it was fine, wanted a second opinion,

 

[Flob]

Yep, when you measure crank end float you generally set a dial indicator up on the nose of the crank and push the crank forwards/backwards, towards the gearbox and away. It's in the order of .1-.2mm so naff all really... If you have >1mm clearance the crank end float will never cause the crank to contact your pump.

If your mind clearance was 0.5mm or less I would be worried.

 

[Struggler]

consider me reassured.

I will come and hurt you if my pump and crank find themselves in holy matrimony.

If your crank shifts over 3-5mm, you've got bigger problems 😂

I'll take that as a thank you

Put it this way, if your crank moves that much, it's already left the engine 😂
