Cam Tensioner Rod, Springs and Bolt
« on: Today at 03:38:47 PM »
Hi all,

It appears a previous owner has done a bit of a diy job on the camchain tensioner. The rod has been replaced with a cut bolt and there are no springs. Adjustment was done by a bolt and locknut to push the makeshift rod down manually. And the rod lock bolt doesnt appear to be correct either.

I have one of the new bronze bushed adjusters ready to go in, just wondering what the best course of action would be? I have a spare plug bolt and it looks like you can get the proper rod from DS, I've seen new lock bolts too. But the springs seem to be unobtainiable.

What do we think would be the best way forward? I have took some pictures also.

Thanks, Dylan

Dave Silver does a pattern pushrod but its all steel, no rubber pad.
You can get an tensioner plunger lock bolt kit from Honda Classics if the thread in case is OK , springs have be nla for some time but you  can use a bolt and lock nut down the capped off hole.
I would helicoil the two holes for the horseshoe bolts

This is the manual adjuster on ebay, TTR 400  is a member on here but in South Africa, may be worth a PM to him
