I've got to remove the fuel pump, replace the diaphragm and replace the pump on my 103e.

I've not done one before and the bit I am concerned about is how to properly locate the rocker arm when I replace the pump.

The workshop manual states the lever must lie between the camshaft and the crankcase wall. Access is difficult and no way will I be able to see what is going on so it has to be done by feel.

Any pointers on getting it right or am I overthinking it...

Thanks

You're probably overthinking it. When you replace the pump just insert it with the arm as upright as possible when you pass it through the block casing.

Hi
I think you'd be hard put to get the lever behind the camshaft.

Thanks all for your help.

I haven't come across the exploded diagram of the fuel pump and location of the rocker arm and as they say, a picture paints a thousand words - or something like that...

The workshop manual is a bit confusing in that it also goes on to note "The lever must rest against the cam and not be located so that it touches that side of the camshaft near the centre of the engine"

I can't quite make sense of that so thought it best to ask those that know Smile

Hello Des. The manual is warning you quite properly that it is possible to fit the pump with the lever beside the lobe, you could happily tighten the bolts and not feel anything wrong.
Perhaps the manual has the following information but just in case, when assembling the pump and it comes time to tighten the screws around the body the diaphragm must be held at full stretch by pulling back on the lever and then tightening the screws.
When a motor has been around for a while there is a good chance of non genuine accessories being fitted so it can save a lot of trouble to check that the pump suits the cam. Turn the motor so that the lobe is at it's highest point then hold the pump in it's proper position against the block. If it will not face up to the block with reasonable pressure a spacer will be required between the pump and the block. There might have been a spacer when new and fitting without it has damaged the diaphragm, or it might be the wrong pump.

Thanks John, it's taken a while but I think I now understand the warning in the manual about the lever position. I think it may be a bit by chance if it goes back in correctly but I'll keep it as straight as I can when I locate it into the block.

I'm pretty sure it is the original or at least a correct part pump and the tip about when the body is tightened, re the diaphragm is very helpful.

I haven't got the pump off yet as I'm waiting for a repair kit but the diaphragm is very brittle around the screw threads and just breaks away so hoping it will be an easy fix.

Hi
FarmerJohn has got me thinking. Why didn't they mount the petrol pump using studs? Then there would be far less chance of getting it wrong because you woulldn't be able to tip it in it would have to be moved in along the studs horizontally.

It's that long since I fitted one I had forgotten they used bolts, in fact one which I did, had a short lever and a straight rod cam follower passing through a hole in the block.

You were right, I was overthinking it. The pump refitted straight in although a bit of a fiddle to get to one of the nuts as you really need a thin wall spanner to get onto it properly.

I think it was safe to say the diaphragm had seen better days....

(Sorry the pic is so big)
