Product Information

Full details

This Sealey Valve Spring Compressor (VS153) is designed for mechanics working on OHC, OHV, and CVH engines. Its primary benefit is its universal jaw capacity, allowing it to handle a wide range of valve spring sizes on most small to medium engines. A potential caveat is its suitability primarily for OHC engines, with general use advised for OHV and CVH types.

FAQs

What types of engines is this valve spring compressor suitable for?

It is suitable for most small and medium sized OHC engines, and for general use on OHV and CVH engines.

What is the maximum size valve spring this tool can accommodate?

The universal jaw has a capacity of 60mm to 155mm.

What does 'parallel lift action' mean?

Parallel lift action means the jaws move in a parallel plane, providing a controlled and stable compression of the valve spring.

Does the tool have a safety feature to hold the compressed spring?

Yes, it features an automatic lock that holds the jaws in position once the spring is compressed.

What is the throat depth of the compressor?

The throat depth is 160mm, indicating how far into the cylinder head the tool can reach.

How much does the Sealey VS153 weigh?

The nett weight of the tool is 1.72kg.

Can this tool be used for DOHC engines?

While primarily designed for OHC, its universal jaw may allow it to be used on DOHC engines, but careful assessment of fitment and stability is recommended.

Troubleshooting

Jaws not gripping securely

Ensure the jaw capacity is within the 60-155mm range and that the jaws are positioned correctly on the spring retainer. Check for any debris or damage on the jaws.

Mechanism feels stiff or difficult to operate

Clean the mechanism and apply a light lubricant to moving parts. Ensure no foreign objects are obstructing the parallel lift action.

Automatic lock not engaging firmly

Check for wear on the locking teeth or mechanism. Ensure the compressor is being operated smoothly and squarely to avoid undue stress on the lock.

Tool slipping during compression

Verify correct jaw positioning and ensure they are fully engaged with the spring retainer. Do not force the tool if it feels unstable.
