Title: 10 thous bearings for Fulvia 1300 crank Post by: jonamery on 17 November, 2023, 04:38:16 PM Good evening all,
My crank needs a 10 thous grind and I wondered if anyone has any suitable new old stock Vandervell bearings available for sale? Mains and big ends. Many thanks, Jon Title: Re: 10 thous bearings for Fulvia 1300 crank Post by: lancialulu on 26 November, 2023, 03:53:03 PM I have +30 Vandervell NOS big end shells

The repair manual only shows two undersize bearing sizes (10 and 20 thou) but LanciaLulu is saying he has 30 thou bearings. Does that mean it is acceptable to grind the crank to - 30 Thou?

Paul if the scroing is bad I would get another crank. I have a good standard 1300 S2 potentially for sale......Title: Re: 10 thous bearings for Fulvia 1300 crank Post by: jonamery on 27 November, 2023, 04:27:54 PM If you take the crank to an engineering company they'll be able to advise, would be a shame to scrap it without further investigation.
Title: Re: 10 thous bearings for Fulvia 1300 crank Post by: Spider2 on 27 November, 2023, 04:57:52 PM Mine is a 1300 S1 engine but apart from the pilot bearing I think the crank is the same as an S2. Am I correct and one just has to change the pilot bearing?
Title: Re: 10 thous bearings for Fulvia 1300 crank Post by: Spider2 on 27 November, 2023, 05:12:04 PM I have been recommended CMS in Bracknell as a good machine shop. I will take the crank there for their advise.
Title: Re: 10 thous bearings for Fulvia 1300 crank Post by: lancialulu on 27 November, 2023, 07:00:50 PM S2 needs to be fitted with 9mm pilot bearing which is a unusual size (30m dia) but available.
Title: Re: 10 thous bearings for Fulvia 1300 crank Post by: jonamery on 28 November, 2023, 09:31:52 PM I have a crank at cms in Bracknell at the moment, and a block being bored to 80mm. They're also gas flowing a head.

That is for an S1 crank. S2 has an outer diameter of 30mm from memory.629-2RS1/C3 SKF Deep Groove Ball Bearing 9x26x8 Title: Re: 10 thous bearings for Fulvia 1300 crank Post by: Spider2 on 29 November, 2023, 10:43:48 AM Hi Jon
I would be very interested with your rating of CMS, especially cost wise. This engine overhaul project of mine may be an expensive mistake as it is in far worse condition than I first thought. One idea was to convert to 1400 cc as you are doing as the bores will need a deep grind and as I need new pistons and rods I may as well create something a bit special, as long as the costs don't spiral out of control. Would appreciate your feed back. Cheers Title: Re: 10 thous bearings for Fulvia 1300 crank Post by: jonamery on 29 November, 2023, 02:47:16 PM Hello, they aren't cheap but I'm confident they do a good job. This is my second 1400 build and the first one is going well. They pressure tested the head on this build and found a leak, they have milled out the offending part and fitted a new core plug. I suppose if this detail had been missed it would have caused a lot of trouble further down the line.
Notes.. Cps for pistons, I have spare rods if you need? I have the head gas flowed and fit 1600 valves. Title: Re: 10 thous bearings for Fulvia 1300 crank Post by: jonamery on 29 November, 2023, 03:49:45 PM Also, I've now found some +0.10 vandervell bearings.
I have got a set of vandervell mains and big ends STD if anyone needs a set, Jon Title: Re: 10 thous bearings for Fulvia 1300 crank Post by: Spider2 on 29 November, 2023, 03:51:52 PM Yes, Quality does not come chaep.
