Hi Rod ..I have been away for 2 weeks ..Simpson desert KTM bike run as a support vehicle ..The best way is to have a crankshaft grinder finish the thrust faces in journal , but it is not a high powered hi performance engine , you could clamp your two bearing halves together and on wet , Kero or Diesel or WD40 , wet and dry paper on a face plate or piece of glass , carefully reduce the flange thickness evenly on both sides till correct ..with regards your rings , the thin spacer bands are used where compression ring clearance in the ring land is excessive , usually the top compression ring , it must be machined on a lathe , a little off each side of the land ..cheers Vern

Rod,

I got bitten by the overwidth thrust bearing problem a while back when rebuilding an engine.  I told the engine shop about it, and they were very co-operative.  They said it was a very simple (for them) operation to grind the thrust faces on the crank to suit the bearings.

If you have a favourite engine shop, talk to them and see what they can do.  The problem with "enthinnening" your thrust bearings by hand would be ensuring that the thrust faces stay square with the crank axis, and that you take an equal amount off each face, so the crank stays in its correct position fore-and-aft.

Well going through this process is to test us all I am sure.

I put the new main bearings in the "new" block and measured up the tolerances and happy to say they are in spec, which I was hoping as the crank has done very few miles since it was reground 30 odd years ago.

In this thread (http://forum.fefcholden.club/index.php?topic=5966.msg173654#msg173654) a couple of years back I spoke about possibly finding the source of some engine noise that over many years we could note find. I also discussed possible excessive end float. Well this definitely wasn't the issue. In actual fact it is / was completely the opposite - no float at all.

When I put the new front intermediate main in (thrust bearing), I struggled to get the bearing between the thrust faces of the crank. Mmm what is going on here??? I thought I would try the old one which still looks serviceable. Still the same result. I was starting to think that I had been supplied with the wrong bearings even all the other mains were in spec. I looked at the box and found a sticker on the inside which indicated that in addition to the bearings being oversized (10thou) the flange is also overwidth. Looking online ACL indicated the more oversize the journal bearing, the wider the flange is. I confirmed this by getting the thrust bearing from the spare crank and sure enough the bearing cap slipped inbetween the trust faces of the crank easily (confirmed with a venier as well). Clearly the machine shop didn't machine the thrust faces 30 years ago to accomindate the oversized flange.

I think what I am going to try is face the surface of the flange bearing in the same manner as this article suggests to get end float between 3 and 8 thou.

Please tell me if this approach is wrong or not or encourage me to have a go. I am a bit hesitant.

Have a ripper. Cheers Rod

I couldn't agree more with the previous comments.

This forum has been fantastic!!! The willingness of so many people to graciously and genuinely pass on their knowledge to others has been fantastic in keeping our passion alive and well.

I to visit the site every day and have seen the drop off over time. I get disappointed when I can't read everyone else's posts.

I don't do Facebook which is a choice I have made because of the work I am in and having seen many negative outcomes with others in using it. I know it is a great communication tool and maybe I need to move with the times. I can see the post in the Facebook page, but I don't think it has the same level of "community" that this page has developed over a long period of time.

I hope the forum has many years of happy sharing ahead.

Cheers Rod

Hi members , I decided to do some preventative maintenance on the ute today, thought I would spray fish oil inside sub frame members, where possible. Started near spring hanger sub frame area but my little radial sprayer wouldn’t enter small drain hole. I started prodding around with coat hanger wire and after an hour and a half this is the result ! And it’s still coming out. Ute must have spent its life in the country.
