From memory the metal backing strips are about 0.8mm thick, but you could easily go much thicker if that's what you've got.
Your existing strips may be fine for reuse too.
Thank you. Very helpful.

Have ordered all the parts (hopefully) that I need for this job. I have been Googling for a free parts manual because I might renew some pins & bushes around the bottom of the dipper and linkage area but can't find anything. Does anyone have any suggestions please ?

Thanks for that. I have ordered the wear pads & backing metal plates from Vicary. I have bought stuff from them since Simon was in short trousers !.

Yes, I know, but I have a service manual and also a spares manual for all the diggers that I've ever owned but just fancy a spares book for the one I have now. I like to check part nos. before ordering.

Yeah - I have a suggestion - don't bother.
If I were any closer, you could have mine - it's very disappointing.

Basically, you find the part you want in the drawings, note the page No, drawing No, item No - give that to a dealer who can turn it into a Part Number you can order.
There are no Part Numbers in the Parts Book.

As an example, the wear block backing plate is: B4-6-4-41
It's a start, but it won't tell you the Part number is: 331/30894


The benefit of this system is that it doesn't go out of date as parts are improved / substituted / replaced, but means it's not very helpful to the end user who wants to use non-oem parts.

The best I can suggest is to use JCB's online parts list. Enter your machines serial number (450xxx) and work though the subsection to find what you need.

Thank you for that information. I just don't understand why that is the position though. It's crazy. We all have to buy spares at some time or other for all our machines. I have spares books for tractors, combines, balers, etc. all have the part nos. which I quote to a supplier and, if they are up to the job, can tell me in minutes if they are in stock. Thanks again Gecko but I find it utterly bizarre.

EDIT Ooops, I did it again. I started ranting before I finished reading your post @Gecko. Thak you for that link to the parts. It's not perfect but it's somewhere to start.

I was just playing with the dipper page and the part numbers appeared : This page. and every other page, is showing me part Nos.
Yep! - so much more useful than the Parts Book.

For what it's worth, the publication number for the parts book is: 9800/9701, but the website is so much more useful (not that it's perfect)

There is a parts book on fleabay at the moment. (same as mine)
The exploded diagrams are great and help (you know what to expect before you get there), but they are the same drawing on the website.

Thank you. That's useful. A bit more research to determine if it's the same model as mine is needed.

Oh.
My service manual covers SnNo's: 400000~460000, so there must be a fair amount of overlap.
(edit)
My parts manual covers SnNo's: 430001 on
It's the differences that'd catch you though.

O.K. Put the wear pads in today. I did it the lazy way, i.e. didn't take the extending dipper frame off, I just wangled the adjusting pads and the wear pads in by either pressing the end of the dipper on the ground to get the bottom adjustable pads in or by lifting it up for the top set and vice-versa for the stationary top pads. I am retired these days but if I'd had the guys around me who used to work for me I would have taken the whole lot to pieces as has been explained earlier in this topic.
I bought new adjusting pins that, because I am using the locknut method of keeping them tight (hopefully !) I bought them 1/4" longer than the originals. That is not quite going to be long enough because of the amount of thread being taken up by the half nut. It's O.K. for now, I have been able to adjust the pads to what they should be but for anyone who is going down the same route as I did, i.e. locknuts instead of washers , and whose machine(s) are doing a lot of work I would suggest 2" long at least. They are 3/4" UNF bolts.
I am going tostart a new thread because I still have a "clangy" bucket and new pins and bushes aren't going to solve the problem as I have found out after fitting the wear pads.
And finally, thanks to everybody who has contributed to this topic. You have all been very helpful.

I wouldn't say lazy way as getting the rod end pin of the extender out takes a lot of heat and in my case when had to renew rod as ram cap unscrewed had to use the 3t mini digger with pecker on to hammer it out due to lack of grease nipple on rod end

due to lack of grease nipple on rod end
Was the nipple damaged or never fitted?
Mine (P8) has a nipple on the rod end of the extender, but nothing on the cylinder end of the dipper ram.
At some stage a fight was had resulting in more than a little brutality
