FlatRacer BMW R2v exhaust nut heavy duty steel wrench tool

FlatRacer BMW R2v exhaust nut heavy duty steel wrench tool


Heavy duty steel exhaust wrench tool to undo the notoriously recalcitrant BMW exhaust rose nuts that hold the exhaust manifolds to the cylinder heads. 

Unlike the similar use wrenches made of alloy, out tool will not bend, break or buckle under stress. In fact, it is an overkill for the job.

Quite often brute force and even chiselling is required to undo these exhaust nuts, especially if in past maintenance has been neglected as some copper grease should be applied periodically.

Having used some of the more common alloy wrenches available on the market with mixed results (we had at least one that broke), we've decided to commission the manufacture of these laser cut, 8mm heavy duty steel BMW exhaust nut wrench tools.

Incredibly strong, sturdy, heavy, capable of withstanding serious force, it will last for years to come and make light work removing the BMW R2v Airhead exhaust and maintaining these notoriously corrosion prone exhaust nuts.


IMPORTANT:

Although our tool, being made 8mm thick steel, can withstand a huge amount of stress, care should be exercised when undoing the exhaust rose nuts as too much force applied can easily ruin the cylinder head threads, a very common and well known problem. 

If the exhaust rose nuts prove too difficult to move, apply a good rust penetrating oil such as Wurths Rost Off or similar and leave it for few days, regularly applying a fresh dose every so often. 

Try to apply gentle heat (heat gun) to the exhaust nuts, it may help undo it.

Move gently the tool back and forth in small increments and keep an eye for thread damage/galling. Lubricate as required and let the material cool down between moves to undo the nuts.

When re-fitting the exhaust rose nuts, apply a small dab of copper grease to the threads thus making it easier for the next soul that needs to remove them.


Outstanding sturdiness, quality and durability. Precision made for a perfect and accurate positive fit thus no slop present which reduces the chance of fin damage on the nuts. If the fins are bent or damaged, you may need to bend them back to the original shape in order for the tool to slide and engage.
