Fitting petrol pump points

Post by **Squiggle** » Wed Jul 15, 2009 8:40 am

Hi

After the dizzy heights of winning First in Class at Herts rally, car travelled home on a breakdown truck on Monday! Did look sad.

Hoping it's the points on the petrol pump.

Any tips/tricks on fitting them would be most welcome.

Probably fit them tomorrow ready before the Bedford branch T-shop run [plug] on Sat.

Thanks

Just follow the comprehensive instructions in the workshop manual - page B2 onwards!

Moved to the "Mechanical" forum from "general discussion", as it is a mechanical query, not general discusiion.

More 'electrical' I would think!
Isn't it amazing though how discussion topics swing from one popular topic to another - for a while it will be discs/drums - then 5 speed gearboxes - then diff ratios - then 1275 engine conversions - and now it's all about petrol pumps! Must be the warm weather affecting the pumps I think!

Moved to 'electrical' then! All the recent fuel pump postings have been in 'mechanical' but either way, it isn't a 'general discussion' topic.

What we need is an eletromechanical thread!! No I was only joking!

you are correct roger,the pump is elecrtic and mechanical

Sorry.

When your screwing the diaphragm to the points before and during setting, hold the pump with the points facing down or else all the wee brass spacers fall out. Hope that makes sense.

The later pumps switched from those fiddly metal donut-shaped spacers to a moulded plastic spacer that's easier to fit. I've also seen one a plastic one that was in four parts.

Thanks for the replies.

I was hoping someone would say there is an easy way and you just undo one screw, pop the new points in, then tighten the screw

Not high on confidence and I did read the manual............bit overwhelmed.

Might get it done by the garage this time and resume such things when my confidence returns. Ho hum.

Meanwhile, happy to get on with the rust removal, spraying, saddle soaping etc....................beats housework any day !

You can...
Remove all the gubbins and the outer part of the points. Count the number of turns to remove the old points from the central screw.
Fit the new points to the same number of turns and reassemble and fit the outer part of the points and put the little wires back in the same place!
If it works when connected, measure the points gap when open (to do it without sparks push the central screw against the spring).
If you need to change the gap, add more or less turns between the points assy and the central screw (dissassemble, reassemble etc..). If there's no gap - it won't pump, and you need to adjust until you get a gap.

Don't forget to clean the points with some fine emery before using them! some have a waxy coating to increase shelf life

Thanks Ray. I like the work gubbins!

www.thefreedictionary.com states:

gubbins - something unspecified whose name is either forgotten or not known; "she eased the ball-shaped doodad back into its socket"; "there may be some great new gizmo around the corner that you will want to use"
