Renault Temis Transmission Problem

[ridger]

No, it isn’t, it’s the main clutch slipping. Now loses drive when in 2 wd when drilling through a tough patch in a high gear. Also slips when you apply the brakes now. There is sometimes an accompanying graunching noise, sometimes not, but I think that’s just normal gear train rattle, backlash.
I notice in the workshop manual you need a fair selection of factory supplied distance pieces, mandrills and gauge tools to set up a new clutch. Diagrams but no dimensions of course. Suppose I will have to ask an old specialist.
A very good tractor when it is actually going.

Wouldn't worry much about special tools, my dad is a mechanic (not a fitter) and has no special tools and has never been stuck yet

We have got away with it before on simpler smaller machines. Only way to find out is to try I suppose. We can split the tractor etc to save some hours then seek help as, when and if we need it but wouldn’t want to get it all back together and find it’s wrongly set.

If it is 4wd pack you dont need to split it will drop out the bottom when you get the 4wd shaft out the bottom from what I can remember

 

[DrWazzock]

Just the fwd shaft to remove then I can split the tractor at the clutch.
How do these shaft couplings come undone do they can slide along shaft and let it drop down? I could maybe just leave shaft and let it slide apart but fwd is engage so I’d need front wheels off ground which isn’t handy.
There is a pin in each coupling. Does it bash out? But it’s slightly recessed at each end. Interference fit or spring loaded like a PTO shaft retainer pin? (Lowest part of photo soaked in diesel)

Tapered pin in the lump on coupling nearest front axle

How do you know which way it’s tapered?

You have a 50 50 chance of getting it the right way, just give it a go, no joy try other way
They slide towards the middle and shaft drops

 

[DrWazzock]

Thanks. It can soak overnight.

 

[DrWazzock]

Well that’s it split. All looks a bit oily, clutch included. Possible leakage through green seal where splined shafts meet. Spigot bearing in flywheel completely gone. Won’t have helped seal. Time for a cuppa and a sit down.

We used to have a Reno Temis. best thing I ever did was load it on a lorry bound for Cornwall.

I wonder if it fell off in Lincs.
Potentially a pair of clutch discs, a new spigot bearing in the flywheel and some seals on the shafts and I’m running again… till the next problem.
Just trying to understand the manual. Setting up the clutch fingers again and centering everything without the factory supplied mandrill/gauge tool will be tricky bit.
These things seem to take me forever but there is plenty else to do as well.

Have a look once you get the green seal out, I cannot remember if it was the B17 or the B13 gearbox, but one of them you had enough room to get 2 seals in, and we used to knock the first seal in future and a second seal up to it,
For 5he sake of a fiver if you can get 2 in, put 2 in

Thanks for that. This is the B13 gearbox. I’d say that seal has let oil into the centre of the clutches. Crankshaft seal seems reasonable, thankfully.

 

[Pennine Ploughing]

Yeah it will be a B13 box, but cannot remember if it or the B17 have a deeper sleeve,
You have a look and decide if enough room

Clutch plate worn out. Down to the rivets, below min thickness.

 

[DrWazzock]

Flywheel face doesn’t look too healthy.

 

[Pennine Ploughing]

Aye its seen a bit of work,
Are you going to skim it

Mulling it over. I was wondering about just bunging in a new drive clutch disc and seeing if it cured it. I’m sure the flywheel is out of tolerance on flatness though. Quite a ridge at the edges of the wearing surface. Not even sure there’s enough left to machine it flat without getting out of spec.
Edit wonder how deep the cracks go?

 

[DrWazzock]

My gut feeling is it needs a new flywheel. The cracks look too deep to me.

 

[Pennine Ploughing]

Ih there deep and the face is uneven, may be the best way if your keeping it, as rough face will chew the new plate
