Tag to Tag yes. Torqued to 38ft lbs

[locky7101]

yes, if my conversions correct thats 51.5nm, il double check the caps tomorrow but i'm pretty certain i've put them tag to tag

[locky7101]

a few pictures of progress:

All the big ends should have a bit of side to side movement on the journal... if one hasnt then thats the one with an issue

it's either no.1 or no.4 as i took these off and it turned over with eas so im gonna try this weekend, what if one of the conrods is too tight?

[locky7101]

ok, took all pistons n conrods out and gonna start again and do it slowly making sure it turns over ok one by one. il double check everything again and find out why it's not turning smoothly. see if i can find a problem

[locky7101]

ok put pistons in one by one and tried them all individually and the conclusion is that NO.3 is the only one that when torqued up doesn't need to be turned over by a socket on the pulley nut and will go round smoothly just by hand. so now i don't know what to do. does that mean the conrods are warped or something?

Very cool project thread. Love this Mini. Keep the updates coming, im enjoying it.

[locky7101]

cheers mini-mad-craig, i hope to have it done by end of june but this hold up with the crankshaft not turning smoothly is denting my shedule as i'm unsure what to do next with it, if the conrods are locking it up then im guessing it means new conrods, which isnt good, anyone help?

[locky7101]

ok, tried again today, put the pistons in with no rings so there was no resistance from that, broke a ring in the process!

also found out again that when the conrods are torqued up the only piston that moves freely is NO.3

i noticed a slight nick in the big end on NO.2 which maybe a cause but i'm lost for ideas now as to what it is as it all points to the conrods, whether they got damaged or something i dont know. anyone got any suggestions?

[locky7101]

ok conclusion, no.1 and no.4 had the wrong caps on (needed swapping)
although in my defence they were delivered like that so i assumed they would be matching but a check of the grinding marks proved to be useful!
so iv got three pistons in and turning lovely, no.2 still being a pain but i think it just that little nick on the face thats causing that as it's hitting the crank. so iv now got to order some new rings as i got heavy handed and wait for them to arrive before i progress. then i can get on with the timing and what not which is all ready to go.

well i havent updated this for a while, tbf iv spent little time on it as iv been busy with work and what not (world cup - waste of time) ok well got new piston rings and fitted them so all pistons are in and its moving much smoother,

iv got the timing gear on and going to attach the gearbox this week and may put the clutch on also

i want to get the cylinder head but i got robbed on holiday in spain and they took a load of money so im waiting for insurance to pay out and then i maybe able to purchase it finally
apart from that long time no posting

[danie garry]

ah poo with the getting robbed, hope it gets sorted
the rebuild is lookin good tho

[locky7101]

done this afternoon on it and got the gearbox on

new gaskets and got all the bolts put in and looking good!

also popped the oil pump in and got to put the clutch on but need to clean the casing and give it a lick of paint as it looks a little rough atm

more to come sooooon ...
