With today’s spare parts availability, mechanical problems on a Triumph TR6 are relatively easy to repair. We at Dandy Classics have many Triumph TR6 parts in stock. Thanks to workshop manuals and various internet forums, even unexperienced mechanics can already perform many basic repairs themselves. But what are the most common weaknesses you should pay attention to when purchasing or servicing a Triumph TR6?
The Triumph TR6 was built from 1968 to 1976. These sports cars are now over 40 years old. Of the cars still on the road today, most will have been restored and rebuilt at least once. In the case of a good restoration, attention will have been paid to all the details of a car. But under a shiny new coat of paint, it is sometimes hard to see if a car is really healthy and solid. During the inspection of the body, be suspicious of poor repair work around typical weak areas: sills, floors, lower front and rear fenders and the edges around headlights and tail lights. Here, years of mud collection have often led to rust damage.
The main area of attention is the chassis. If there is any rust damage that needs repair, it is best to separate body and chassis. This encloses hidden areas and allows the complete chassis to be bead blasted and properly repaired. Are there any traces of welding? Take note of whether this has been done properly. An important weakness are the rear traverse beams (where the rear suspension’s swivel arms are mounted). Good quality replacement sections are available, but they must be well aligned before insertion. Incorrect allignment will have consequences for trailing of the rear axle, which affects handling and tyre wear.
The mounting points of the TR6’s differential can suffer from tearing, especially on cars driven fast. In this case it is also easier to separate the body from the chassis, but it can also be repaired from below by removing the differential.
As with many british sports cars, TR6 gearboxes and differentials do not have eternal life. Gearshift problems and whining noises are indicators of work ahead. Our workshop performs rebuilds for both gearboxes and differentials of the Triumph TR6.
Parts that wear out relatively often on the Triumph TR6 are:
clutch (and release bearing),
fuel pump (this is a mechanical membrane pump that can dry out)
rear IRS suspension parts (bearings, drive shaft, U-joints).
