LAFORMO Twin Cam Chain Tensioner Tool for Harley 1999-2006 - Holds Primary & Secondary Tensioners

Specially designed tool that securely holds and relieves pressure on Twin Cam chain tensioners for 1999–2006 Harley Davidson Big Twin engines, making cam removal and installation safer and quicker.

If you work on 1999–2006 Harley-Davidson Twin Cam Big Twin engines, this dedicated tensioner tool from LAFORMO gives you controlled access to the primary and secondary cam chain tensioners so you can service cams without fighting spring pressure. The package includes two retention pins and one cam chain tension tool; note that a large 1-1/4" socket or compatible spanner is required to operate the tool. It is not intended for 2006 Dyna models and does not include printed instructions.

How does this tool make camshaft removal and installation easier?

The LAFORMO tensioner tool unloads the spring pressure on both the primary and secondary chain tensioners so the camshafts can be removed or reinstalled without tension fighting. With tension released, you gain stable, repeatable positioning of the chains and cams, reducing risk of misalignment.

• Releases tension from primary and secondary chain tensioners.
• Makes cam removal and reinstallation smoother and safer.
• Helps avoid accidental timing chain jumps during service.

Which engines and model years is the tool compatible with?

This tool fits Harley-Davidson Big Twin Twin Cam engines built from 1999 through 2006, excluding 2006 Dyna models. Confirm your bike is a Big Twin Twin Cam before purchase to ensure compatibility.

• Compatible: Big Twin Twin Cam models 1999–2006.
• Not compatible: 2006 Dyna models.
• Ideal for workshop technicians and DIYers working on these specific years.

What comes in the kit and what additional tools do I need?

The kit contains two hold-retention pins and one cam chain tension tool. You will need a large 1-1/4" socket or a matching spanner to rotate and operate the tensioner tool during use. Instructions are not supplied with the kit, so basic knowledge of Twin Cam timing procedures is recommended.

• Included: 2 retention pins and 1 cam chain tension tool.
• Required separately: huge 1-1/4" socket or suitable spanner.
• Note: no printed instructions—experience or service manual recommended.

Can this tool help diagnose worn tensioner components?

Yes — by allowing you to compress and measure the tensioner spring load under controlled conditions, the tool helps reveal weak or worn tensioner parts. During cam service you can compare actual spring resistance with expected behavior to identify tensioners that need replacement.

• Enables checking spring load on both chain tensioners.
• Helps identify worn or weak tensioner components during inspection.
• Useful for preventative maintenance and confirming repair quality.

Who is this for? This LAFORMO tensioner tool is designed for motorcycle mechanics, professional service shops, and experienced home mechanics who maintain 1999–2006 Harley-Davidson Big Twin Twin Cam engines. It’s especially helpful for anyone doing cam or timing-chain work who wants a safer, more controlled method to relieve chain tension and verify tensioner condition. If you lack the required socket or are unfamiliar with Twin Cam timing procedures, consider consulting a service manual or a trained technician before use.
