tensioner pulley different for 6/7 bolt?

[1Gina2G]

Is there a difference between the 7 bolt and 6 bolt tensioner pulleys? are they the same? How can I tell what I have?

I swear someone mentioned they were different but a search brings nothing. thanks

Same pulley, but the hydraulic tensioner is different you have a 6 bolt and 2 different options for 7 bolt.

Thanks, I have a 6 bolt block with a 6 bolt hydraulic tensioner and tensioner arm. I was just wondering about the timing.

Are there any differences with the crankshaft sprocket? I'm just not sure what I have as far as some of these wheels, I know the crankshaft pulleys are the same but what about the sprockets?

1g trigger plate (6b and 7b) is different than 2g, but all your pulleys and sprockets will be the same (except 95-96 intake cam gear due to the CAS)

I can say for a fact that the idler pulley (one with the brown seal) is different from 6 to 7 bolt. I had to put a washer under the 6 bolt idler pulley when mounted on a 7 bolt motor mount bracket in order for it to be in line with the timing belt. It was 1mm off. I believe the pulley on the tensioner is also different. I'll have to double check.

The trigger plates are the same thickness so when doing a 6 bolt swap, they just interchange.

Mitsu PN for the pulleys are the same 1g and 2g.

Please look these part numbers up. Not all the parts are the same although they may seem similar. There are 4 different part numbers for the hydraulic tenssioner. 2 different balance shaft tensioner pulleys and 3 crank trigger plates and 3 different harmonic balanacers. Where did I get this information? Straight from the dealer ASA software.
Folks please stop telling people "the parts are all the same" blah blah blah without looking them up. If you said something more objective like all 6 bolt hydraulic tensioners are the same you would be correct. I see post after post people sayiing all sorts of parts are the same across all model years and it's just isn't true. Objectively I haven't seen the dealer parts lookup be wrong yet although there are plenty of arguments around april of 1992. Hope this helps somebody. To the OP the timing belt pulleys are the same. The balance shaft belt pulleys are not. BTW 6 bolt and 7 bolts is not enough information. 7 bolts covers both 1g and 2g. The timing belt tensioners are the same for all 7 bolt but the hydraulic tensioners are different for 1g 7 bolt and 2g 7bolt. Sometimes more information is necessary. Questions about 6 bolt are not model specific. A six bolt only came in 1g cars.

I have been doing this for well over 10 years or more. I have used these parts on numerous occasions the orange pulley (idler) and blue pulley (tensioner) are interchangeable without any problems. I had caps until I upgraded to windows vista, I have ASA now. Before you start calling people out and pointing fingers ask some questions. Read a little, learn a lot.

As a side note the 7 bolt tensioners (OEM) have the last 3 digits of the part number cast onto them.

PS ASA BLOWS! I miss CAPS.

Just to clarify the bolded portion above, the idler pulley is not interchangeable with the tensioner pulley. They are obviously different.

What I meant was they are interchangeable between years, not with each other. Sorry for the confusion.

The statements and questions aren't specific enough. The statement was general. I wasn't meant to evoke a reponse. Merely point out the questions and statments need to be more specific or we could be providing bad information to the OP.
Even the OPs question was too general. Tensioner pulley for what? Timing belt or balance shaft belt? Assuming the timing belt then yes the tensioner pulley is the same. Balance shaft belt, no it is not. There are two different timing belt idler pulley part numbers also but they are interchangeable with a part supercession on the bolt
Thanks for the 10 year qualification, I'm 20 years in. Just wanted to get complete statements .to the OP.

Thanks for speaking up about being specific, I try to be specific as possible with all my questions and replys on here, I was not aware of there being 2 different tensioner pulleys as I've decided to do a balance shaft delete.

The concern is that I only have a tensioner pulley from my 95 7 bolt block and now I'm putting together a 6 bolt block & 2G head setup so I was just checking what parts from my 7 bolt motor I could use on this 6 bolt, I know I could use the crankshaft, water & idle pulleys. But I guess it's also okay to use the tensioner pulley on the main timing belt for either or. Thanks again.

1G Pully bolts have to match Power steering pump especially. I cold not find my original and went out to match it. It has to be a specifc length or it will never be tight enough. Luckly I found a 1991 Plymouth Laser and it matched.

That's what I have. 6bolt block. 2g head. 2g motor mount. 6 bolt idler pulley with 1mm washer.

I installed it normal and the timing belt was hanging off the pulley. I put the 2g and 1g pulley on the table next to each other and there was a 1mm difference. The washer fixed it.

 

[pauleyman]

with 1mm washer

Elaborate please. The idler pulley is the same part number for all years. There should be no difference. The only possible exception is the early 90 models the bolt did not recess into the pulley so to interchange with a new one you also had to change the bolt.

 

[ed1380]

Ill get part #'s. I don't want to redo the timing to take a picture of them side by side.

 

[DECODER22]

idler pulleys are the same its the tensioner pulley you have to worry about the wrong one will either be 1mm off or rub
