or did I fail is it 50 times up and 50 times down equaling a hundred

[Webby the Bear]

yep 50 up and 50 down totalling on hundred strokes :-)

[tidla]

For those joining the thread at page 6..

The discussion is engine revolutions per minute.

[albitz]

Webby,if you still have Ralf and the heads are off ? get someone to turn the engine over on the starter for a few seconds and you will probably be surprised how quickly the pistons go up & down the bores even just at a speed which would hardly register on the rev counter.

Hmmm , got me thinking so how would you measure if the car is performing the correct rpm ... strobe or something  Keep up the good work mate and pick that tutors brain

It`s great learning new stuff
Go for it now....... in 5 years time you`ll thank yourself for doing it.

Day 9 to 11...... finally I hear you say 

Ok well as I mentioned I have had a H&S Assignment to do. All done and handed in 

However, on Monday we started engine work. Day 9 to 10 was practical and Day 11 was theory.

This is the pushrod engine (from a Ford Fiesta I believe)....


This is the little engine shop...when I say engine shop it's just a room full of engines on lifts specifically there to work on... as you can see my mates are working hard while i take a breather to take the photo 



This is us after we'd ripped the head off and we were able to turn the engine over on it's special mount, pull the sump off to reveal the holy grail of shafts  . I found out that those bracket looking things with the big bolts are the big end bearings.  and they attach to the con rod.



ooooh....a quick shot of the head off.... 



This is me and my new friend lol i removed the clutch and fly wheel, timing gears and crankshaft..... and then he takes the photo plaudits 



This was day 10..... we'd put back together the bottom end including timing up the timing gears and putting the sump back. all nice n tidy and then we set about taking the valves out of the head and removing the collets by using the valve spring compressors.....



....then we got the valve, covered the valve stem in grinding paste and used a stick to twist the paste in to the valve seat until it turned from ''rough'' to ''fine'' and this apparently is making sure the valve seats perfectly.....




Anyway, as mentioned before in theory i learned about RPM..... unbelievable as mentioned before.

but most importantly i learned about the four stroke cycle (suck, squeeze, bang, blow  ) and we'll be doing more theory on that as it was just an introduction to it this week.

as i mentioned before i have completed the H&S assignment. although its not interesting i do plan on posting my assignment on line for completeness and for any real boring b......s there are on the forum

At least your getting into the swing of things now the H&S is out the way , when we did auto mechanics we had a triumph stag to work on ...it was the tutors

The boring H&S is useful, and should be adhered to...

Yep... "Gay" glasses have their uses

[Webby the Bear]

Haha yep they should be adhered to.... but it aint 'alf boring.

Also I believe I misquoted in one of my photos....

The one where I said we had the sump off to reveal the crankshaft.... the big end bearings are not the ones with the big bolts.... theyre actually the ones that are being undone by dumb and dumber to get the pistons out 

[Shackeng]

They are, I believe, the main bearing retaining bolts.

[aaronjb]

Main bearing retaining bolts are the large bolts sitting on the main bearing caps in this picture - 8 of them and they hold the crank into the engine.

What you're (well, your assistant ) busily undoing are the big end bearing caps (big end bearing being at the larger end of the con rod and holding the rod to the crank) - which is I think what you corrected yourself to say and what Shackeng also said.. but I just felt like saying it again

[Marks DTM Calib]

Hateful shitty old engines those old Ford pushrod engines

True, but even they won't keep sparks from a grinding wheel or drill bit shrapnel away from your face
