That is pretty much what I did!! As soon as you can get the nuts on the studs then go that way!!
Good luck, Andy

Hi all
bit more progress but the crank became virtually immovable when I tightened up the carrier nuts only to 15lbft so I took it all out again.
I am guessing but I think it has no endfloat on the crank

The first thing I would check is that the bearing is tight in the carrier and hard up against the shoulder of the carrier. In my car the bearing, when located by the pin, was not fully engaged in the carrier, so I removed the pin and pushed the bearing fully home in the carrier. Even so, there was no measurable end float, but importantly the crank rotates easily within the crankcase.
If the bearing is fully home within the carrier I wonder if it is possible to shim the carrier away from its mating face on the crankcase thus creating some end float!! The shim would have to take the form of the gasket to prevent oil loss!!
Good luck, Andy

Do you need the full 50 litres of cleaning fluid? My admittedly smaller one functions on 5 litres of Gunk. Alternately is there a cheaper substitute like paraffin maybe?

Is the front bearing in the correct position as well ? (no gasket)
Is the gasket behind the bearing carrier the correct thickness ?

That is the reccomendation from the manufacturers, with regards to using parafin I thought about it then remembered I set fire to my fathers garage one time...50 litres of parafin...Hmm |

Hi all
update on the crank..My mate Terry came over and between us we got the crank in and rotating with the carriers just nipped up. What we did first was slacken off the bolts holding the front bearing carrier so the crank could be jiggled about alittle and then with some grease applied to the rear bearing and journal we managed to get the back carrier fully in without a gasket. By fitting the starter dog bolt thingy into the front of the crank which has a 24mm? flats as well we got a socket on and as I went round tightening up the rear carrier nuts Terry could turn the crank. What was noticeable was that as the carrier went in the crank would tighten up and as the nuts tightend again the crank would slacken off and be easier to turn. In addition copious amounts of engine oil made the crank easier again to turn.
Clarkey and Terry

If I can add my two pennorth, I know nothing about Appia engines, like most of you do, but I have built a lot of race and road engines and I wouldn`t be happy about the state of that bearing. It looks badly marked up like there`s not enough running clearance. I would advise that you purchase some " Plastigauge" and check the clearances on all the journals. The instructions are in the packet. It really is essential when reassembling an engine because you never can be sure that the crank has been ground correctly, I don`t care how good you think your machine shop is, check it! Also it appears from your photo that the thrust face hasn`t even contacted the crank, maybe the radius hasn`t been ground correctly? Not casting aspersions, just suggesting you check.

Thanks Jaydub I think the problem is the fact the front bearing was pushing the crank slightly offline and that meant the rear carrier fouled the crankcase when you tried to insert it. the crank has not been reground and the bearings are standard

"then remembered I set fire to my fathers garage one time" That seems a pretty good reason to be cautious about paraffin!

Sadly no progress as having to make room for the S2 from Scotland I have had to cram lots of stuff into the room where the rebuild of the engine is taking place. So the theory is we can do a round of musical chairs some space will appear. Having put the staircase in to the roof of the 2 rooms we have a bit more elbow room.
