Frequently asked questions

What is the 40.40.89 valve spring compressor used for?
The 40.40.89 valve spring compressor compresses the valve springs on a cylinder head so the split collets can be released. It's used when removing and refitting valve springs, retainers and valve stem oil seals during cylinder head reconditioning.
When do I need a valve spring compressor?
You need a valve spring compressor whenever you're replacing valve stem oil seals, springs or retainers. It holds the spring compressed so the two split collets can be lifted clear, freeing the retainer. Doing this without the tool risks launching the collets or damaging the valve.
Can valve stem seals be replaced at home with this tool?
Replacing valve stem seals with a valve spring compressor is achievable for an experienced DIY mechanic, but it typically needs the valve held closed with compressed air or rope while the spring is off. Work methodically to avoid dropping a valve into the cylinder.
