Gearbox Rebuild - Clive W

Many of you may know my brothers Evo 6... recently featured in the August issue of Banzai magazine.













Engine built by Mark Shead at MA Developments and custom aero corrections done by Radu at RCBS. Mark needs no introduction as one of the best Evo engine builders in the country as well as Cosworths he’s made a very good name for himself. The aero on the car was bodged together by a company up north and then completely reworked and engineered all round corrected to function as desired by Radu at RCBS – a top mechanical engineer specialised in 4x4s and race car builder on the side – he builds cars which compete in the Dakar Rally on the side line.

My brother lets me drive the car and I find all the weakest parts, break them, repair or buy stronger and then fit them. Whoever buys this car from him when sold will be getting a seriously well maintained and no expense built strong all round machine!

The most recent thing I broke was the gearbox, it exploded from one too many launches.

After doing some research it seemed the best person for the job was Clive W. This was after speaking to not only him, but other companies that also do box rebuilds.

Those of you that don't know of the work Clive does or his history may like to know that not only is he a perfectionist to the micron, but also once found himself top of his game working on aircraft and being top of his field as the person able to sign off the planes worthy to fly. His knowledge and skills in aviation engineering is sky high (excuse the pun).

However Clive decided to move away from that and concentrate on nothing else but Evo gearboxes and has engineered some very impressive modifications to improve on oem design and function.

Anyway without blowing his trumpet too loudly, it’s for anyone wanting a gearbox rebuild to call him and hear this information first hand.

I felt extremely confident that there was no better place to go to for an Evo box rebuild. Unfortunately there are companies out there that are not to be trusted and I’ve learnt of one which talks a good game, but in fact has poached info directly from Clive and are passing it off as their own. I’m not going to name and shame, but be weary the company is out there right now and trading… or better yet just use the gift to box rebuilds that is Clive!

The box Clive built used parts from later Evo’s with many benefits. I would go in to detail of exactly the advantages gained by these parts, but think its best coming from Clive himself when he responds to this thread. I wouldn’t do it justice if I tried to explain, but trust me there is a list of tasty upgrades, which serve purpose.

You’ll notice the transfer box had a ‘Clive special’ upgrade whereby the internal bolts which are prone to becoming loose (and which were loose in this case), have been re-engineered and Clive’s fix will ensure this does not happen again. Tried and tested for one or more of his customers in rally use.

While the box was out I thought why not a fresh set of friction plates, I’ve had the box out twice now and I never want to do it again… up on axle stands doing this job laying on your back is not fun. The old friction plates are in decent condition so will be selling them… although one is a tad worn… still if anyone has a twin plate then these might be of interest.







And in she goes…











The box and clutch (and a new set of front pads) are currently being bedded in and once done there is a remap on the cards. However the feel of the gear engagement is unbelievable, it feels so positive and solid, there is no play at all (again Clive will expand on a few upgrades he’d engineered which provide that extra rigidity over the oem components that now eliminates a couple areas of potential play).

The 4.11 final drive will see the car to 194mph at 8000rpm if there was ever a need for it… driving away after doing a bank robbery to help pay for car parts could be one of those times.

He's done all my transmission and a great guy. Unfortunately I have come across said guy passing work off which is sub standard and selling stuff at ridiculous prices with wrong parts in them haha. only one man to go too is Clive.

Box looks great hope it works well for you

This guy's name wouldn't happen to rhyme with Cycle Barker would it?

Fantastic - I just had some bits of my box rebuilt locally by MitsiArt. Mind you it wasn't in THAT STATE!

ONLY (he says) needed a brand new Reverse gear, synchros and ALL the bearings replaced...

Just been for first oil change and feels lovely. Reverse still bedding in though.

Got one of these fitted now too:

Thanks Alex, nice to meet you, the car looks awesome, congrats to you and your brother!


Unfortunately, the trader mentioned (not a trader on here BTW) PM'd me in 2014 asking for one of my built boxes, but his only intention was to get as much information from me as possible so that he could try to copy what I do. After giving him a quote I realised all he wanted was info, because he asked for intricate details of exactly what I do inside the box so he could copy what I do. And hey presto, after a month or 2 he started advertising high spec boxes on e-bay under the name Transbox (ebay user name acecarparts)

I've had a few customers who have gone to him first thinking it is me - I am not Transbox (or ace car parts), my company is Transmission Dynamics Ltd.

So, he is listing high spec boxes on E-bay and Facebook, but he doesn't actually understand what I do, so the description is basically BS.

As an example, he replaces a taper bearing with a ball bearing on the output shaft. He did this because in my quote to him, I put 'upgraded bearing' due to the standard bearing being on it's load limits. But due to not understanding, he fitted an off the shelf £8 ball bearing!

The gear ratios in his e-bay advert are copied directly from a post I made on the MLR, even though my post gave a rev limit of 8000rpm (specific for a customer) and the standard rev limit is 7700rpm, which you would use for a generic ratio table.

From the pics of the box he is selling for £3.5k, I can see it's an Evo 4 gearset with standard centre diff output shaft, non standard syncros, original worn thrust washers, wrong bearings, and a load of BS in the description!

Most of the description is copied straight from my PM to him, but he doesn't know what I actually do (even though he asked for details, and then alarm bells started ringing and I told him to do one!), so has just copied with some extra BS added such as;

"20%-30% gain in strength after superfinishing" - Superfinishing doesn't increase strength at all, that is impossible, only a bigger gear of a material with a high tensile strength can do that!!

"Modified bearings are used throughout the build to cope with the added stress and load on the components" - The bearings in the pic are standard cheap off the shelf bearings, not only the wrong type, but the wrong shape where the circlip supports the bearing, meaning the circlip can flex and allow the bearing to move. The standard mitsubishi bearings for the Input shaft are a special design, and cannot be bought as an aftermarket item - thus why they are expensive.

"along with hardened steel thrust washers" - The thrust washers are hardened steel as standard, and the ones in the photo are the old damaged standard ones, not even new, to allow correct tolerances.

"Modifications are made to the oiling system of the box to allow increased oil flow."

Another copy from my PM to him.

"Hi Spec components used throughout offering the most enhanced build possible to make the transmission that lasts race after race." - High spec??!! Obviously wrong bearings, a standard old Evo 4 gearset (which has many inherent problems) with no new gears is high spec, best of the best!!

Sorry for the off-topic and rant, I'm sure you understand why. I've put an immearable amount of time and effort into developing the standard gearbox to the best it can be, and someone just steals your info and then tries to profit from your time and effort. Good luck to people who develop their own stuff, but selling crap off the back of someone else isn't on.

He'll probably look at the info you posted and start adding it to his e-bay adverts.

His user name on the MLR is FQ340 MR, and you can see older posts from him asking where to buy Mitsubishi parts from, and simple questions about transmission stuff.

Looks good that's why I recommend you to Clive. Did you change the outer metal disc in clutch rebuild.

Is that the metal ring which sits behind the pressure plate Mark?

I must confess I didn't. Should that have been changed?

Great pic thank you

And that little do dar you have on ur input selector is similar to what Clive engineered on my bro's. Takes away the play, nice little mod

Clive - I was thinking that when doing this write up that the trader in question would likely poach bits and pics.

I just hope ppl will do their homework before parting with their hard earned money. I'd hate for anyone to get ripped off, I certainly wouldn't wanna be victim to it.

Also how upsetting would it be to think you have a properly built item to only find out after when it fails that u got ripped off. It's a sad thought

It's the metal drive plate I am talking about as they tend to bent which causes problems with the clutch releasing.

Mark.

That's a Ross Sport shifter bush (same part) good little improvement for removing external slack in the mechanism.

Yeah, he'll probably update his e-bay advert with the latest info!

Someone will get their pants completely pulled down if they buy that £3.5k box.
