nigethomas Posted September 26, 2015 Report Share Posted September 26, 2015 Hi im in the process of building my engine Back together on my 4a.have noticed the sprocket for camshaft has quite sharp points at the end of teeth.the crankshaft sprocket looks to have more thickness on the ends of the teeth.will cam sprocket require replacing or is this normal?

RogerH Posted September 26, 2015 Report Share Posted September 26, 2015 Hi Nigel, sound like the sprocket has done enough and needs retiring. The chain will also be close behind. Roger Quote Link to post Share on other sites
