LT230 - Rebuild Help


need4speed

Recommended Posts

Ok so im part-way through my LT230 rebuild. Im at the stage of setting the diff bearing pre-load. Theres no way i can afford all the 'special tools' that the LR rebuild manual suggests using. Does anyone know of a way to do this without spending ££££ on all the LR tools.

Ive had a look through some LT230 rebuild posts on here but have not found any definitive info on this part of the box.

I'm not familiar with this bit of the box in detail, but what turns the diff section you are trying to preload? I take it it is a torque to turn setting that you are tring to set? In that case, is there a component of the old case that you can weld a nut to so that you can put a bar type torque wrench on it in order to measure the torque to turn? Can you do it by turning one of the output flanges....if so you could put a torque wrench on the centre nut.

No it is not a torque-to-turn setting. Its actually preloading the bearings that carry the diff itself within the casing. Thanks for at least replying though. I'm really surprised that the supposed wealth of knowledge on here hasn't done this before.

Or....maybe, just maybe that's why a few folk have had probs with ashcroft LT230 recon boxes.... Just a thought.

Preloads ALWAYS need done. Especially if using a different casing from original.

bit below the belt,

you phoned me today, I was very busy but I knew it was you, I stoped what I was doing, took the call, explained how we do it and you are just looking for 'light drag' and you write this ?

I give free advise to hundreds of people every week which is no problem but I don't expect to then see comments like this,

don't bother phoning for any more advice !

I've never heard of problems with David's gearboxes or Transfer boxes and their aftersales service is second to none.

Because of his reputation I bought both my gearbox and transfer box from him and would do the same again.

David and Ian have always been extremely helpful and offered free advice on this forum for some time.

Maybe, with attitude like this and your previous comment, those that have, simply chose not to reply.

Wow. Isn't it funny how whenever there's a slanging match going on everyone is quick to jump in but whenever you ask for some technical info that requires some thought all you get is tumbleweed...Dave I did end by saying that maybe you were busy but don't worry I won't be calling again. The 'not to loose, not too tight' wasn't really what I expected to hear. I already know that but hey if that's the technical way to set bearing preload who am I to argue......

The technical way is to get the recommended tools in the manual and do the whole thing properly.

You asked for help without this expense.... What do you expect?

Clearly David and the team know the preload by feel now and it's going to be near impossible to share that feeling over the phone!!

Calm down, reflect and review matey.

Setting a preload by feel is not that uncommon. The difference is the knowledge to do it effectively and correctly. Using the correct wedges/shims/guages is fine, but after using them, you turn the relevant parts by hand, so you feel it and get to relate one to the other. You do it enough times and what you do by hand is pretty much the same as all the technical equipment. If you want to do it expertly and to spec and have no previous experience, then put your hand in your pocket and buy the rather expensive tools to do it :)

In the past I have bought a recon gearbox from a so called gearbox specialist in Oswestry called L**** thankfully I believe they are no longer in business, the box I had from them failed within 6000 mile. the 3rd gear had split into 2 sections, outer teeth on one and inner spline on another, the firm only changes the gearbox for me after I got quite confrontational with them.

I have had a transfer box, cv joints shafts and an underdrive from Ashcroft, and I have had excellent service and wouldn't hesitate to use them again if the need arises.

:D Good video though!

:D yeah it is!

Great video btw Dave :)

I can also vouch for the quality at Ashcrofts having bought a recon exchange LT77 a few weeks ago which I'm very pleased with! Dave was extremely helpful with all questions I had regarding gearboxes and transferboxes which I thought was excellent customer service. I will definitely be using them again in the future

Yes its all very well saying dave et al are soooo good they can set preload by feel alone. What a load of rubbish. Its easy to tell if a bearing is too tight but what if its too loose. Can you really tell if the bearing is 2 thou slack by feel. Don't think so. I've lost my job and my workshop has been flattened so yes I'm trying to do this cheaply by not sending away to get done. Are you really saying that in the whole of ashcrofts workshop there is no LR setting blocks to give me a measurement? If not then ashcrofts have just taken a guess at all the diff bearing preloads. I guess the advice would have been different if I was about to spend £600....

It is called experience in rebuilding boxes, which is what ashcroft can and you cant (at the moment). Fair enough if you are having a go yourself, but try to get your point accros without slagging people off, something else ashcroft can and you cant.

Daan I'm not slagging anyone off who didn't have a go at me first. I've been on this forum for years and found it very good and the people very friendly but to be honest regarding this matter your all just opening your mouths first and engaging brains second...

Did Ashcroft say anything to you before you said this?

Or....maybe, just maybe that's why a few folk have had probs with ashcroft LT230 recon boxes.... Just a thought.

I think this is what is being referred to in 'slagging someone off', I'm sure with some careful thought you can see why this upset Ashtrans...?

BTW, setting swivel bearing by 'feel' is something I do as well, and we all know how critical that is for truck wandering/tramlining/shakes, but never had a problem here either.
