TD5 Heavy Duty Torque Converter Fitting Kit

Technical

It is very important that you locate and install your torque converter correctly.

One of the most common causes of failure is the torque converter not being located correctly onto the pump before fitting causing the pump to be broken on start up.

To avoid this we would suggest that you stand the autobox upright and lower the torque converter into the bellhousing.

When the torque converter has fully located onto the pump it is essential to then measure the distance from the bellhousing front face to the torque converter feet ( also known as the flange that the flexplate is bolted to).

Once the torque converter is inserted and checked make sure it does not fall forward when offering the autobox up to the engine.

Do not be tempted to pull the gearbox into position with the bellhousing bolts, it should fully locate on the engine with no gap between the bellhousing and engine block.

With the autobox fitted to the engine, check that the converter will rotate freely and has a small amount (about 2mm) of end float.

Bolt the converter to the flex plate using loctite or similar on the thread of the bolts.

Ensure the breather vents well away from the exhaust.

Torque Converter Distance Measurement (bellhousing face to torque converter feet) 

The depth is 73.

The stock TD5 converter has 3 bolts, the new one has 4; the 4 bolts sit in a different place and it’s a little harder to access the new bolts. We can supply a couple of parts to assist you, see related parts below and you will also need a ratchet spanner to fit the 4 converter bolts but to hold the bolts in place and create friction for the ratchet to click you will need to drill a hole in the bellhousing and use some long nose pliers to hold the bolt in place whilst you tighten it with the spanner through the normal lower access hole.

There is a link on our website to a template so you know where to drill the hole.

The two tools you may require are:
1) 28mm dia hole saw, available on our website
2) 13mm ratchet spanner, available on our website

Please note this is only recommended on a tuned TD5 engine. If you put this on a stock TD5 engine it will be detrimental as the engine will not have enough power to get up to enough revs for the turbo to start working due to the lower stall speed, this results in the engine ‘bogging down’ at say 2000 rpm and very poor acceleration.

Please call if you have any other queries.
