Andrews, Chain Drive Conversion Camshaft Set 31N /.510"

Excellent cam for 95" engines with compression ratios 9.8–10.2. Lower TDC lift for easy installation. Similar to TW37 with different timing. Works well with both carburetor and injection. Standard valve spring OK. RPM range: 2,200–5,800.

These camshafts are used to convert a 99–06 Twin Cam from the original “silent chain drive” with spring-adjusted tensioners to “roller chain drive” with hydraulic tensioners that operate via engine oil pressure. This roller chain and hydraulic tensioner system, which is a vast improvement over the early system, is used on all 06–17 Dyna, 07–17 Softail and 07–16 Touring models.

Note:

Camshafts are for use with splined (00-up style) driven gears

For 1999 Twin Cams, splined 503575 driven gear must be purchased separately

See catalog for additional required parts

Suitable for:

99–06 Twin Cam (excludes 2006 Dyna) (NOW)
