HI I have read with much interest all of the many and varied posts I have brought a 3d mk2 which I would like to know the year of and what engine is in it for servicing purposes. Prior to my purchase it was given a "Dulux rebuild". The old girl needs full re hosing which brings me to my next question where can I source 5/8 bsp field fittings (reusable) in the UK as 5/8 field fittings in Australia are like gold as only Ryco seem to make them DHL air freight to Australia is 74 pounds for a 30x30x30cm x 15kg which makes it very viable to buy them and import them (a 5/8 x5/8 90 bend is 24.20 pound).
ID plate : 3D 116797/3
384B 218947
44011
Any help would be very much appreciated.

Hi Mark and welcome I am sure somebody on here will be able to offer you some good advice on your JCB 3D

Mark,
The "JCB 1945-1980" book by Michael D.J.Irwin has a section on early JCB serial numbers. It lists the JCB 3D as starting at S/N115823 in 1977, and 127484 in 1978, so this should put yours as an early 1977 model. The book suggests the MkIII came in 1977, but assume your is therefore a late MkII.
I've a JCB 3C MkII, S/N 114300 which is 1976 and is/was fitted with a Leyland 4.98NT engine. I don't know if the 3D used the same engine or not but can't see why it wouldn't. (The Leyland engine become smokey after a while, so I removed it and fitted a John Deere engine which worked well for a number of years until I was coerced to put it back into a John Deere - currently eyeing a nice little mercedes engine which I feel would look well in it!)
I sourced some 5/8" bsp reusable hydraulic fittings on-line a few years ago, but can't remember exactly who from, but have done a bit of searching and see a company called QTP (https://www.qtponline.com) supply them under their code 1795 for a 90-deg. version, but don't seem to offer anything else. The site suggests they ship worldwide, so might be worth a look. (Personally, I got annoyed with these odd sizes, so cut up a 5/8" fitting and a 1/2" fitting, welded them together and converting my flexible pipe work to 1/2". It may be a restriction but just don't tend to over rev the engine when operating the hydraulics and all’s been well to date.)
Hope that’s of some use.
Colin.

Re: New owner JCB 3D Mk2 qestions
Just seen this post. maybe you've got sorted by now but here's a link I'd bookmarked. Haven't used their services as I rarely look for reusable fittings now but may be worth a call if need be.

As CHM123 posted,the engine should be a Leyland 4/98NT.
The dipper looks like it's telescopic? Would be rare or an after fit on a MK2 I'd think?
