Land Rover LT77 reconditioned Gearbox

Land Rover LT77 GearboxOne of the biggest issues we see with old gearboxes is failure due to lack of maintenance. Most people tend to look after their engines well and service them regularly by changing fluids and filter etc. Sadly, they often over look the transmission. A gearbox needs regular maintenance too.

With the LT77 you should be looking to change the oil yearly at the very least, maybe more if you are clocking up high miles. The LT77 takes around 2.6 litres of oil, if you neglect to change or maintain your oil level in an old gearbox then you are just asking for something to go wrong. As you know Land Rover’s are notorious for leaking oil, and if your gearbox has a leak then it wont talk long for you to lose half of what should [...]

Land Rover LT230 Reconditioned Transfer BoxThe Land Rover LT230 transfer ‘box is a very simple and strong unit. It takes a beating due to the nature of what it is, and with what we as drivers ask from it. This like hard off-roading, heavy towing and general abuse or high mileage use. Add that to a general lack of maintenance and a slightly flawed design and you might find that your transfer ‘box is dying for a rebuild.

Earlier LT230’s suffered from wear to the splines on the input gear due to the fact that oil struggled to lubricate these splines. As a result the splines from the output shaft of the Main ‘box would slowly wear also.

This wear becomes apparent in use. Clunks, clicks, judders are a few usual sounds you might hear. You may also identify [...]

Land Rover LT230 Reconditioned Transfer BoxAll the gearboxes built at Syncro Gearboxes are completely stripped to a bare gearbox casing so that each and every part can be inspected. Every ‘consumable’ part is discarded and the core parts are retained.

After which the casing along with all relevant parts is dipped into our decarbonising fluid bath to burn off all traces of oil, grease and paint. A choice of specification is decided with the customer and then the gearbox is assembled with all tolerances and torque settings checked and set along the way.

The original helical gears are checked and replaced if required. The gearboxes selector hubs are stripped, the gear selector forks are checked for wear or damage and replaced if necessary. Any parts that are found to be damaged or warn are replaced and the rebuild continues.

Synchromesh Transmissions

 

Most modern cars are fitted with a synchronized engagement gearbox from the factory to deliver smooth, reliable, and quiet operation, which is paramount for a daily driven vehicle. Synchromesh transmissions operate using a collar that applies force to a cone-shaped clutch attached to the gear. The collar allows the shaft speed of the gearset and the input shaft to be matched or “synched” to the output shaft prior to the collar locking into place and initiating a shift.

Synchromesh gear engagement is best at lower engine speeds and requires a bit more time compared to a dog box, to facilitate shifts. Limitations of synchromesh gearboxes in high-performance applications include slow upshifting at very high engine speeds—e.g. 9,000 rpm—and slow downshifting, as well as the need to fully use the clutch.
