A quick one reading Andy engine building thread what is the crack with shims and endfloats?? how do you know you need shims and how do you check the crank endfloat without a fancy dpi??
just thought i would clear this up before i start the build over the weekend.

[AndyMiniMad.]

Ypu can check the crank end float by pushing the crank all the way over to one side and then use your feelers in between the crank and the thrusts...push the crank away from the flywheel end. You can get different sized thrusts to get the end float bang on.

If I remember right my end float was 5/6 thou and measured using a magnetic base and dti gauge

[AndyMiniMad.]

Sorry I should have explained a bit better...these are the thrusts that im on about..



You need the caps fitted but not nesessarily properly torqued down. the crank will move back and fore just a tiny bit. If you can hear it clunking against the thrusts then there is a good chance you have too much end float. Any more than 6 thou and you will need to get fatter thrusts..if its tight, like one or two thou then I would consider giving the thrusts a quick rub on a flat surface with some 2000 grit wet and dry. rub the trusts against the paper and not the paper against the thrusts..(if you see what i mean)..but so long as the crank turns smoothly then even at 2 thou it will be fine..
Im sure you already know this but the primary gear end float and the crank end float are two seperate things..I feel silly even mentioning that, but you never know who's reading your thread...so im covering my bases..

[jameslearwood]

That's great makes more sense guessed the floats were separate but what do they look like wish Haynes had decent photos. What I need is a picture book with every part in it with names and brief description

[AndyMiniMad.]

They are like half moon shaped. silver on one side and brass coloured on the other. there should be four of them. the two that have lugs on them are for the cap and the other two slide in like in my picture. Minispares sell them at different sizes... but if you have the ones that came out of your engine im sure they will be fine..just be carefull not to mix up different sized thrusts on the same side of the crank..

[PhilipGCaldwell]

also, make sure you get them the right way round, I had a friend rebuild his 1330 and he fitted the thrusts the wrong way, unfortunately to say, when he depressed the clutch the engine stalled straight away, not good, engine out and strip down again!

bearing side faces the crank

just read my build thread, endfloat on mine was 5 thou

Graphogen graphite paste any suggestions where i can get it from not in AV taylors, Halfords or Unipart only seems to be on ebay?
Is there something else i can use on the bearings? guessing graphite grease is no good?

[miniman92]

Torco engine assembly lube is great and it's less than half the price of graphogen.

Just going to go with wynns oil additive and oil in a 50/50 ratio as cooperman advised firefox cheers though

[jameslearwood]

Right the crank and cam shaft is in

where am i lining the camshaft up with there is three parts on the cam that sit in each bearing can't to seem to get them all flush so do i just have it flush at the oil pump end?

by turning the crank easily with two fingers is this meaning it turns, as mine does but with some resistance probably the weight of the crank i think its what it was like when i was taken it out.

thrusts its the grooved copper side that faces the journals and the smooth side faces the bearing.

going to post piccies in a moment.

[jameslearwood]

Camshaft and crank installed





side note are the cam followers meant to be a snug fit with the lube.

Is this the cam shaft correctly lined up?

[jameslearwood]

I havent a clue but do this piston rings look okay i.e the gap.




Cheers people
