Coach Gearbox repairs at VOR Transmissions

SERVING BUS & COACH OPERATORS FOR OVER 30 YEARS

ZF 6-12 Speed ASTronic

Bus & Coach Gearbox Repair

Thirty five years of providing transmission servicing to thousands of UK bus & coach operators. We give a cost effective differential and coach gearbox repair service, from  a specified repair (cost of repair) to a bench up overhaul (vor repair) and everything in between.

STOP! Before you start taking gearboxes out, or buying another, first of all tell us what’s going on. We may be able to narrow it down a little. Problems could be in the box, or the range, in the lid, in the controller, in the air manifold, a poor solenoid, sticking valve, whatever.

On any given type of transmission we see the same thing occurring time and time again. Often we can advise the source of the problem because of past experience and things may not be as bad as you first think. It’s in our interest, as well as yours too, for us to be efficient, quick and cost conscious.

So why is my gearbox crunching into gear?

So why is my-gearbox crunching into gear

The engaging teeth should look like the left picture, nice & sharp so they slide past each other. When gears are crunching, the teeth have worn away and are consequently banging together…….you don’t need a new box.

So why can I only select forward gears?

So why can I only select forward gears

Simple, could be just the turret section. If we find faults that match the reported symptoms then it’s fix the turret and no need to touch the box and this can often reduce the cost by thousands.

So why is my gearbox dropping out of gear?

dovedale joint

Another common fault, could be just worn sleeves and cones. They should lock together like a dove tail joint because, when worn, they don’t lock and hence the box drops out of gear. It’s a simple fix, we just fit new ones.

If you have one coach or a hundred, having a vehicle off the road because of a transmission fault will cost you—firstly time and money and finally hassle. Let VOR take care of your bus or coach gearbox repair so you can concentrate on better things. Just get the unit removed and give us a call and we’ll take care of the rest (we are happy to remove telmas/retarders and the like saving your mechanics time). We’ll check it out for you and give you a call with your options. You control the costs. Call 0800 018 4141

Typical Bus Problems Explained

What does ‘synchros gone’ mean ?

Synchros Gone

Synchro rings rub against the engaging cones, grip and slow the shaft. When worn down they have no grip. It’s a simple fix, we just reline the unit with a new set.

So why the noise in all gears?

Noisy Gears

Well, many answers, but a common fault is bearing collapse, due to wear, fatigue, or just getting to the end of expected working life. It is a simple fix, we just reline the unit with a new set………….You don’t need a new box.

Box stuck in 3rd gear?

Broken Roll Pin

The smallest of things can cause a major problem. We have lost count of the units that only had a broken roll pin or something just as trivial causing the problem. Some companies advise you need a whole gearbox! (Roll pins are about 8p each).

Bus Operators Beware!

Bus Operators Beware

’COACH’ gearbox components are often of a higher grade (and cost) to the corresponding ’TRUCK’ spec item. In every coach gearbox repair we fit the correct specification components to ensure correct ratios and low noise.
