What do I need to replace?
Stuart Walker - 28/3/06 at 12:52 PM

Hi,

Reconditioning my 1300 X-Flow, got it converted to unleaded etc... Now I'm ready for reassembly.

I've cleaned everything up, but what ancilliary (sp?) parts do people reccomend replacing, water pump / oil pump / starter motor??

Trying to be as locost as possible obviously, but I'd rather replace them now than have something go wrong later.

Cheers!
Stu

Depends on condition...

Water pump - they can seize, and the main shaft seal can leak. If the shaft can be easily spun and it looks in reasonable nick, I'd try it on the engine (although I replaced mine).

Oil pump - there are ways of checking for wear but if it's old, I'd buy a new one. Consider getting a high-pressure one.

Starter motor - If it spins when you apply battery power with jump leads (hang on tight!), the pinion gear is in reasonably good nick and the gear spirals up and down the shaft easily then I'd try it on the engine.

Flywheel ring gear - check that it's got all its teeth, and that they're in reasonable condition.

Fuel pump - if it looks OK, you might as well use it - it's really easy to replace if it proves to be faulty.

Hoses - replace them all!

what does high pressure give you other than sap engine power?

easy way is to fit a spacer behind the oil relief valve to make the spring harder.

you can get high volume ones (I have 1 fitted) which are also slightly higher pressure.

Core plugs. NEVER rebuild an engine without replacing core plugs. A lesson learned the hard way by me!

Oil pump - I just did what I was told!

As far as I can tell, it is capable of pushing the oil through tighter tolerances (which I did try to achieve) and gives you greater leeway when something causes the pressure to drop.

As for higher volume - I was told that it was only necessary if you had an oil cooler, to help shift the greater volume of oil.

In all honesty, the standard pump in good nick kept the engine alive for 50 - 100k miles, so it can't be all bad! That's why I said "consider" rather than "must get".

I had forgotten core plugs - definately replace them as a matter of course. It's always a shock when you remove the old ones...

Have you replaced the timing chain and tensioner.
Sod to get at with the engine in.
Go for duplex if you've got a high lift cam.
