WRC 2017 Mechanical Issues and Failures
Hello all!
I'd like to keep a thread on Mechanical Issues and Failures from Round 1 to Round 13 this year to see what comes up with each manufacture that have produced the new 2017 cars. As we see, so far in four rounds we've got four different makes of car winning rallies.
And... go!
(Starting with Monte)

Do the Fiesta have 1 and only one hydraulic system, or are the gear, centre diff and brakes and other things that uses hyd oil in separate systems?
Basically, have they put all eggs in one basket?

It was always like that - hydraulic circuit was one - responsible for diff, paddle shift, sometimes power steering, etc.
Brakes always separate system.

handbrake is not at the same system as center diff/paddle shift.
its hydraulic but separate system

Did we ever find out what Meeke's issue was on Saturday on the Monte? The one that meant he was running way down the order. Tanak's engine went sick and dropped a cylinder. I think that was it for round 1?

Its tricky to list such failures accurately as teams dont reveal everything, and also some issues were event specific.. ie. cooling in Mexico.
Plus I dont think its fair to treat MSport like the factory teams as they dont have the same support/ budget.

Ogier says, quote: "But then when I took the narrow roads and found some hairpins I realised that this electronic problem we had was not only the boost, but also the central diff was locked and that means we had no handbrake for the hairpins so we struggled quite a lot".

yes he is right. When there are some kind of problems with center diff,its locking,and when locking you cant use the handbrake.
Normally when you apply the handbrake,there is a device that make instantly free the center diff, to don't stress the mechanical components of center diff,and make the car turn easier at a U turn ie. When the diff is locked that device cant work,so you don't have effective handbrake.
That's the ''connection'' between handbrake and center diff is refering Ogier.
The hydraulic part of handbrake is totally different from the high pressure hydraulic circuit for center diff ,gear change.Last edited by dimviii; 10th April 2017 at 18:23.
