Triumph TR4A Body mounting back on Chassis
Here you can see how we placed the body back on the chassis. We have a block and tackle mounted to one of the steel roof beams. This is how we got the body off and how we put it back on. It allows millimetre movement which is handy when you are making small adjustments. Our set up also has an adjusting bar so you can raise either the back or the front of the body tub independently. The video shows most of the process. No matter how many pairs of hands you have available, you'll always need more. Big thanks to my buddy Chris who came over to lend a hand to get the body back on.

Issues we facedWhen you place the body on to its chassis mountings it needs to be dead level as there is not much room for clearance.
1: The speedo angle drive needs to be removed. 2: The hand brake cables need to be just fractionally poking through the bridge on the chassis. Once the tub is on you can pull them through with bullnose pliers. 3: Exhausts - ours appear to need to be set lower. I have a feeling the rear of the body needs to be raised to make them fit. (The fix was to make 2 small semi-moon cuts in the rear valanvce. 4: The metal heater hose needs to fitted correctly or this will foul the bulkhead. Ours has a slight angle to it so we need to get it dead straight. Right now, it is touching the battery box. |
Ride height for the Triumph TR4A
TR4A Ride Height
Exactly 40cm from wheel center to underside of wheel arch. That is 15.75". And....... the most important: car rear should be lower than front by 1.25 +/- 0.25 cm, i.e. 1/2". This relates to the distance from ground to underside of wheel arch.
NOTE: During the rebuild the car looked proud and the ride height all wrong. After a drive and back to the MOT Station (18 miles round trip) it came back perfect. The new poly bushes had settled in - new springs and bushes as well as suspension will sit the car proud and it will need a drive to settle before you start taking it apart again to get the ride height right:-) Have faith!!!!!

Ride Height - Look at the picture below.
This picture is from the Chicago Motor Show. Look at the ride height of the TR4 in the foreground. This car is factory fresh and has not been driven too much and you can see that the car is sitting high. Once driven the springs would settle and the ride height would be correct. You can see the height at the front for instance is very pronounced.
