Ive emailed the guys at RC Lazy and I hope to get a reply. These guys have helped me out in the past but admit it would be easier if they put a number on there as well to contact them. Once I get a reply I will update.

Iso, are you sure this is the case? Please double check as I think its more like 3.175mm, still if you are correct then these are what we need. Now what about the thrust race?

Yes I need to know for sure too as I want to order enough diff and thrust race balls to build four diffs so would hate to get the wrong size parts!

Nope actually they are 3mm.
the sets i have bought all over the world have had 3mm in less they come from the states since so much easier to find 1/8 and they fit they have just replaced them with them. I have bought new diffs from america and they have had the 3 mm balls in them so im pretty sure.

Since they both fit and the extra spacing the 1/8 balls give makes the front diff sitt a little better in the front diff housing at least my last front gearbox was very spaceious.

Yes there are pulleys that uses 3/32 balls but one can say that they are rare special pulleys in the end of the zxs evo line i think you welsh may have some. I do also have diffs with 3/32 balls but they are diffs made for the TF2/3/4 line so they have outdrives in plastic :thumbdown: even kyosho have outdrives in delrin i can get the part number if anyone are interested.

1/8 or 3mm just take the ones that are easier to find

regarding the trust race, dont have a clue but i can check when i get to my parents house.

Iso have a check and see otherwise associated thrust race or kyosho zx5 may be the answer.

Yes my zxs did run smaller diff balls and the out drives were protos, which are ruined but will when i can afford it have a couple of sets machined. The diff quality made the zxr diffs obsolete, super smooth with zero slip.

Maybe trying to make some BK bones ????

Just bought some ceramic 3mm balls. Got six large ceramic bearings for the diffs and layshaft, and hope to get the hubs ceramic bearings next month. Just need the correct size for the thrust race. I dug out my atlas thrust race and are the size of a pen tip. Im tempted to get associated thrust.

So can we confirm that the LA-4 diff balls that the Lazer ZX/X-R and Mid diffs take are 3mm? Where did you source the balls and the ceramic bearings from?

Links on one of my posts in this page. Now all i need is thrust race ball sizes.

Cheers

Did anyone on here just buy the two AR Lazer motor plates, does AR stand for Atlas Racing? I was looking at the and then they were gone lol

They were anodised purple

Its this seller, look in completed items to see them, are the c hubs he has worth getting?
http://www.ebay.com/sch/jethobby*hk/...p2047675.l2562

hasent been to my parents house yet so i cant say the part number but
its an 3.8.3,5 in size .....

mvh Isobarik

Think i have seen those and i belive they where listed as HPI for the lazer then ....

cant find the c hubs that you mention ....

mvh Isobarik

Best c hubs are the teamline ones, the hpi versions tbh were not sold very often so didnt really do well. Rondoolaa has quite a few for sale if interested.

C Hubs are here what does AR stand for, its not Atlas Racing is it?

Could be. They were involved with the zxr and s

Iso,

What do you reckon, 1/20 size thrust race balls, ive measured the standard version and are 3mm as you said, but the thrust were there as well so measured and are fractionally larger than 1mm so guessing its more 1.2 so 1/20 appears to be the size. Only one way of finding out and thats if I buy a set and try them.

For some reason my head is telling me they are 1/16 size?

James, where did you source the larger bearings for the diffs and layshaft?

Ebay worldwide and are acer bearings, size is in the manual and rclazy dont appear to be around anymore so advise finding all diffs balls elsewhere.

They were smaller, as ive measured ones still new and in packet and are just aver 1mm from left to right. The zx5 is 1/16 however am going to dismantle my b2 diff to see the size difference and decide which way to go.

Henrik, did you received my PM's?

yes i will get back to you as soon as i know anything im a bit behind in the ordering situation...

mvh Isobarik

No worries, thanks mate!

Ok guys, the 3mm ceramic balls are a slightly smaller size ball but never the less do fit but do not slot in unlike the original size. they feel nice as well when all attached.

Only issue is the thrust race as the associated B4 thrust race doesnt fit and is way too big so now need to work out what ceramic thrust I can get thats not wider than 1.3mm.

Still good news my latest design rear gearbox CF sides are perfect so have now finished that totally. Im now working on the pivot blocks.:thumbdown:

I ordered some 3mm ceramic balls too, glad to hear that they can be used, is there another size that would actually be the right size?

Speaking of pivot blocks, did you get your replacements from the guy in China, I didn't and they should have come in by now

No but will chase him tonight. Im going to try and find someone in the uk to make them and should be cheaper hopefully

I just emailed him now, see if he replies

By the sounds of it you would be getting some more stuff from Fibrelyte soon so I contacted Stephen about the parts he needs to make for me that you will pass on with the other items you have for me there, hopefully he can get onto them soon

Dan,

I havent had the other bits made as of yet but will ask for it to be made at teh end of the month.

That will be fine, no massive rush

I believe I may have the solution to the ceramic thrust balls. I found that the 2mm or 5/64 associated thrust balls were too big but its possible that the 1/16th size may fit so have bought a set to test. Lets hope.......:confused:

Since i went to the LHS i should have taken the last WBD-2 and then mystery solved...

mvh Isobarik

Yaaay! I finally got one, thanks doug_jb :D:D:D:D:D

Get the BRG-100 for the zx5 contains 8 small trhust balls and 2 washers

WBD -2 contain 8 small thrust balls and 2 washers

Since the zx5 and zxr have the same diameter for the drive shafts in teh the diff ....voila ...

problem solved

class dissmised :lol:

mvh isobarik

First version zxr.

Also theres a lot of AR alloy bits on ebay worldwide such as castor blocks and a purple motor plate for a mk1 zx/zxr.

Just bought a bone of LA232 and a complete LA245 in total silver.

Iso, as no one is in at kyosho in the uk any ideas on where I can buy replacement pins for LAW30?

does anyone know what size the pins are just in case i have some in my box i can send.

I will measure the diameter tonight.

On another front the 1/16 of an inch ceramic thrust balls from much more do fit. Ive put in a total of seven but is possible the eighth will also fit, which if i have time will redo. It feels smooth but as ive tightend all the way up its not yet free enough as it needs running in.

Yay! I feel like I got something right ;D

Im unsure if this is correct but with the help of Kyosho they have goven me a part number 92051 which is 2x11mm so now hope thats the size on mine and Iso's cars.
