Our 1934 Austin Nippy has had a strange issue with its crank shaft spring which got caught inside the engine. As seen in the illustrations below, the spring is meant to sit back however it had moved along the crank shaft and into the engine. This has now been taken apart and amended, meaning the only thing left to do is to take it for a test drive again.
Our 1934 Austin Seven Nippy has been completed as of today and we’re delighted to see it up and running! Gordan and Craig took it out for a test ride and it ran perfectly. With the engine and bonnet back on and all issues resolved, this little Nippy is set to go!
Our charming Austin Nippy has its engine back in which we’re delighted to see. Ady re-linked and re-fitted the engine back in to make sure it now starts fine.
Ady has found that there was water leaking out of the side of the cylinder head so he has fitted a new cylinder head to go back on with a new copper head gasket. His next step will be to take it for a test drive.
These tangled looking metal pieces are fondly named ‘mousetrap springs’ which are fitted on the clutch fork fingers. However, these have unfortunately given in and in the process of their demise, got caught in the clutch. Although we managed to rescue these springs, it has meant we’ve had to take the engine back out of our Austin Nippy Seven and order new mousetrap springs and clutch fingers.
We’re delighted to announce that our little 1934 Austin Seven Nippy engine has been fully restored. We’re currently awaiting the fly wheel and clutch to arrive but otherwise the engine is ready to be fitted back in!
We’ve received our 1934 Austin Seven Nippy engine back and can now begin reinstalling the engine back into the Austin. This little motor will be nippy in no time!
Below you can see the re-conditioned engine with its new crank case from Ian R Bancroft Restorations:
Our Austin Seven Nippy engine has recently been sent off to Ian R Bancroft Restorations to make sure everything is moving, turning and working as it should be as we discovered a crack in the crankcase. Once this comes back, Ady, our knowledgable engine specialist can continue to rebuild the engine.
The Austin Nippy engine rebuild has continued with our knowledgeable engine specialist Ady.
Ady has been working to cut the valve seats, re-bore the engine to take new pistons, white-metaled the conrods to suit the crank shaft, re-profiled the camshaft to fix any imperfections and laid out all the parts ready to place them back together.
Our 1934 Austin Seven Nippy had an issue with rattling pistons that were needing to be bored. We’d sent the components off to Coltec to be pressure tested and bored so that the liner and piston sit in the Austin engine better.
Our poor little 1934 Austin Seven Nippy has had some mysterious leaks. The previous engineer had welded the metal and covered the suspected leaking area with sealant. Unfortunately the sealant had not stood the test of time and came off when we were cleaning the engine.
We want to go the next step and discover why the engine is leaking. Our engine specialist Ady aims to coat the inside with a red sealant spray. The purpose of using a red spray is that it will seep through any cracks and identify precisely where the damage is. From there we can weld only the areas needing it rather than a general area.
Our 1934 Austin Seven Nippy is currently undergoing some open-heart surgery for its precious engine. We discovered a crack in the clutch so both the clutch and the flywheel have been sent away to Norwich Brake and Clutch who specialise in Edwardian and Victorian motors. We’ve also sent the rest of the engine off to Coltec.
