67 cam chain tensioner fix.
I rebuilt my tensioners. Apparently not very well. See pic after 50 miles or so.
It looks like the oil fed ones won't fit the early motor ?? Those collars are new and were tight. Motor was kicking upon stating after disi was out until I got my timing right. ?? What's my solution ? Lyndonhttp://forums.pelicanparts.com/uploa...1587442846.jpg |
Pressure fed won't fit . Did you update the idler gear arms ? How was your rebuild ? How do they compress in a vice ? Maybe get new ?
|
Ok wont fit.
Rebuild went well I thought. I will try in a vice. I did have trouble compressing them to fit into my engine ?? Lyndon |
Those are not the original '67 tensioners BTW. They look to be mid year units, but I can't read the numbers.
At any rate, are they spongy now when you push down on the plunger? They should be rock solid, even after being run for a while. Not sure what you mean by oil lines. Carrera tensioners have external oil lines, but need updated cam covers to be installed. Carrera tensioners are not what you are showing in your picture. |
Install the collars after tensioner is installed.
Use a heavy screwdriver and insert between the idler and the opened tensioner, pressing down until you can tap the tensioner in place. Install the safe devices Bruce |

What I'm saying is I can't upgrade to oil fed tensioners because I have a 67 engine. |

Am I correct in saying that they fill with oil while running . ( splash ) the. Act like a shock absorber. Its like a total loss system as they leak a bit ? Mine are quite springy and stiff. If I fill and bleed them im sure they will be hard again.. My question is they were hard with oil when installed and now seem to have no oil. It also looks like the collars would prevent the oil entering the cup when running 😦 Lyndon |
Is a solid tensioner an option. I. Have run these in bikes I have had.
Many tensioners have a ratchet and spring and the oil pressure takes up the slop till if gets to the next click on the ratchet. Thoughts Lyndon |

There should never be any sponginess to the plunger. It should always be firm and you should not be able to compress it with your finger. The safety clamps are a good idea. Solid racing tensioners are not a good idea. |

Richey asked if you updated your idler arms. If you're using 67 idler arms with those tensioners, they require spacers. No, the 930 tensioners don't have open oil reservoirs like the original 67 tensioners did. The tensioners should not be "springy" when properly assembled and bled. The pistons should be extremely slow to depress. The collars require 3.5 mm clearance above the tensioner body when installed in a cold engine. If the clearance is less, you should remove the collars. |
After lunch I will bleed them again. My issue is They were bled 50 miles ago with the spacers set at the correct distance😦
|
Is the special tool necessary to fit them or is a screwdriver ok

Maybe you should describe how you bled them. By "spacers set at the correct distance", do you mean the safety collars? If so, was the distance set with the tensioners installed on the engine? |

Don't recall the exact method of bleeding . Reading this now http://forums.pelicanparts.com/6126423-post8.html |

No scores etc. After its done I can I can compress it . fit the tool and it will slowly raise after fitting . The oil remains in it but goes from one chamber to another ? Lyndon |

Are you using a 930 tensioner parts diagram for re-assembly? |
