Just wondering if anyone has a link to a diy timing replacement or setting timing. Not that I need the work done but I wanted to know how it's done just in case for future reference. I looked on the sticky's and didn't find anything, I looked on YouTube and couldn't find anything. I'm just trying to learn different aspects of this motor.

 

Honda made engines usually do not need routine timing chain replacement. AFAIK.

 

 

The chain is driven by a small sprocket on the crankshaft, and connects to the idler gear which drives both camshafts.



The TCT (timing chain tensioner) puts pressure on the guide to keep the chain straight.

When you remove the timing chain cover, loosen the TCT, there is enough room on the chain to remove the upper sprocket.
The lower sprocket also drives the oilpump via a small chain. I'm not sure you have to remove this one in order to remove the timing chain. I do think so

When mounting, timing the sprockets is pretty easy, there are some diy's on this forum

 

best to pick up a shop manual if you want to tackle something like that, lots of little details that are part of the project including the timing mark alignment. I have not seen a DIY on this.

 

The book calls for cylinder head removal and timing cover removal.

It can be done by oil pan removal and timing cover removal instead. Save major time.

 

 

Can I remove the timing chain without removing the oil pump chain?

 

Yes you can without removing the oil pump chain and get rid of that TCT and buy Billman's. You're lucky it hasn't caused any significant damage yet.

 

I did but unfortunately not before the chain was permanently stretched.
