timing chain ?'s

[Chevota]

i put the new double roller chain on my 22r but it seems a lot loose. tensioner is all the way out and still has 1/16" after that and when i turn the engine the opposite way it will skip a few links. and ideas why i think that????? :help:

I have a couple questions. 1. Have you put it all back together and started it? 2. Has the cyl head been milled? Sometimes if the head is milled too far the timing chain will always be loose even under pressure because the whole head is shorter.

well my uncle had it just sittin' in his garage. he said he didnt want to use it because it came from a car and thought the heads to be different. but it has been rebuilt. they wouldnt be different car to truck, they are all 22r's arent they?no i havnt run it yet because of the timing chain tensoin concern but i got a dual timing chain kit for it . the kit came with giudes two sprockets and a tensioner and the chain . i had to get a a different oil pump drive and a new cover cuz it wasnt deep enough. any ideas

I don't suppose you could post a pic of the slack could you?

You didn't make the mistake of using the wrong bolt in the top of the oil pump did you?

Look down the well and see if a long bolt is sticking in there holding the tensioner back.

Also, make sure you didn't over-tighten the tensioner bolts. Any more than 12lbs and the bolts will squeeze the housing and bind it up...

no the front cover is still off and tensioner works good i can pull it out and it still looks way loose

How many links are there in the chain?

I think if it is a standard link length, there should be 96 if I'm not mistaken. Maybe you could count them and see how many you have. The dual row kits may very well be different.

I hate to say it, but if there is a lot of slack in the chain I think something is wrong. My chain was pretty tight when I put everything back together.

well i went to the parts store today and asked them and i think that they looked the kit up under 1981 but i need it for an 86 but then again i have an 81 head oil drive ,cover. just counted the one i took off of it and it is 96 and the new one is 98. i think your onto something. i will get after the guys at the parts store. thank you :redspotda

I still do have a single in it... I used an engnbldr single row chain kit with the steel backed driver's side rail.

The double row kit would be nice insurance, but I really wanted the steel backed rail this time. That's the entire reason I did it on an engine that failed with only 12k on it. I can't believe they used plastic rails...

ya no kiddin those plastic ones are s$!t. my kit came with the both of them steel but chain is wrong
