I thought it looked like ti weas turning the wronw way too, but assuemed it must be a camera illusion as a mini inertia starter wont engage spinning the wrong way.

Same, but akes for a consensus from the people around me......... They thought clockwise... might be wrong

clock wise from the rad end, so anti clock wise looking at the flywheel.

Does that mean I can't just go and swap the leads round and get it spinning the right way?

Depends on the starter motor. As mini13 has put, he thought it wouldn't engage the opposite way, therefore it won't work. Have you not got an old starter knocking about?

Right I've just driven to where the engine is and replaced the starter motor, I then had it spinning at speed for 5 mins or so...

NOT SOLVED!

still no oil pressure...however if I've been cranking the wrong way...I take it that the whole system is now full of air, and is this wishful thinking, that will take a long time to compress?

When i took the Feed hose off (banjo end) I had oil spurting out in gushes, not a constant flow, but a constant spurt, second or 2, spurt...
Also when I took the feed off the oil pressure gauge there was the tiniest spurt of oil and a huge bubble of air...

I think you need to investigate,

there must be a leak on the sump side of the pump somwhere.

your oil pump is working then, you wont get a constant flow whilst cranking as the relief valve holds the oil back until pressure is up then it releases it and shuts again, so you will get spurts...thats good news.
I suspect your gauge.

Difficult to get air out of oil pressure gauge feed, even when you do the oil drains back and air again, normal.

That makes sense Minimender...I will try another gauge, although I've seen this one working...

Mini starters can only turn the one way - no matter the battery polarity. But if you have used a different starter - all bets are off. However - I know of NO engine that runs anticlockwise!

This also mean my relief valve is working?

It must have been a starter off another engine, yer i figured that out when I had time to think.

Swapped it for the mini starter and it turns clockwise (from the pulley end).

Still no oil pressure though Roy, any thoughts?

That was an eBay NOS starter motor, it's apparently for a different application as the cables are on correctly..

I wonder how many times it's been fitted and then put back on ebay as NOS.
Are there any numbers on it, would love to know what it's for.

Yer there are numbers, it was NOS it had some kind of ridiculous seal I had to get off...or if not NOS it was refurb!

Looking at the teeth I think it may have been for a tractor, in fact I think it might be for a perkins diesel
