Manual Gearbox - Stick movement while in 3rd

[Lazarus]

Random question, but would it be possible to put the 6 speed unit out of an SLK into a W202 230K? Just curious really...

Hi there

I am surpirsed you have found someone willing to recon it. I struggled. You could probably source a different box for that money but they are scarce. Sounds OK to me.

as long as they can actually do it! How many manual Mercedes boxes have they done. Lots of people can recon an auto Mercedes box but not many will do a manual (successfully!).

It's only a question of parts supply, which thinking about it will be available through the dealer if nowhere else.

A manual box is a pretty simple affair.

There will be worn components such as the selectors or engagement rings.

If you can't do the job yourself then a "recon" is probably a good solution as long as they actually do what they say they will and it is warranted.

Reconning a box is childs play for anybody that can take something apart and put it back together in an ordered and logical fashion. When I did mine in the summer it took 3 days and it was the first box I had ever removed and taken apart, its really not difficult. Most designers (I know I do it) design things that can only be assembled one way to help the muppets that build them in the factories. You would really have to work to get it back together wrong. Chances are its the synchromesh in third which works on a taper lock which obviously isnt locking, reasons for this could just be knackered oil thats full of swarf (generic term for any "lumps" of metal you dont want, this could be filings or peices of gear) which stops the taper lock locking or that fact that it is broken and wont stay together. All gearboxes have a magnet inside them to catch any metal floating about which has iron in it but there is also brass and phospher bronze inside them which will obviously ignore a magnet.

Anyway if somebody has offered 600 sheets to recon a box I would rip their arm off. It took me three days and was OK as I was not working at the time, think how long it takes you to earn £600 and whether you could do the job yourself and then see whether its worth it, thats why I dont do all the work on my car as its cheaper to get somebody else to do when you look at loss of earnings.

I use a Merc specialist breakers in Ireland and they are very very helpful, If anybody has manual boxes they will and they will just courier it to you.

Also to the person wondering if the six speed would fit I would say that it would but thats not set in concrete. I think the box is the same length, the connecting rods may be the same but you will need a new shifter unit, and for gods sake if anybody takes a box off mark up what rods went where because if you dont you mathmatically have 81 combinations to get them back, a little bit of tipex goes as long way......

Also if any manual owners out there look in the side of their box near where the rods are and see a slightly hexagonal black/grey plastic moulding go and get it changed for a metal one. This is what went on mine and for £17+VAT you can save a rebuild or it breaking down, its a worthy investment. I will take a pic of where to look when its light and hopefully get it on here if I can figure it out.

thats all folks, hope this has been some help, my number is 07879 656210 if you want help doing a box and your local or just want a verbal talk-through,

gearbox recon

Hi there
evetualy got round to recon gearbox picked up today fine going up through the gears found a bit sticky in neutral selecting gears and coming down from
3rd to 2nd also selecting reverse a bit sticky garage told me selector rod a bit twisted and rubbing would this cause this prob and should this have been done when gearbox was recond or is this a seperate job if so is it a large job maybe just need some time to get used the box ? any ideas

 

[Dieselman]

Hmm.. odd fault, bent selector rod causing sticking.
Sounds more like new components binding a bit or clutch drag causing the baulk rings to stay locked.

Maybe sticking the wrong description a bit hard to select the gear not that smooth would you still say it is clutch drag if it is new components binding this should clear?

 

[Dieselman]

If it's awkward to select gears from stationary, particularly reverse then I'd go for clutch drag, if it's just a bit notchy then probably new parts needing to bed in.
