185577 updated oil chain tensioner

Since you've already swapped the pads what's holding you back from installing it?

Oh and,

How worn out was the old pad?

 

Seems weird, why would they sell you a whole different assembly that won't work? Why not just sell you the pad?

 

What car?

 

The new tensioner is correct, not backwards, You need the revised mount pin that screws into the front cover and the clip that holds it on. The stop the tensioner rest on also needs to be replaced. There is a TSB on this. Rimcabi shows it on there site. The new tensioner needs to be installed as it is, this is part of the update to prevent the rattle the original one can have. Good luck, Bryan.

 

Oh yeah those are definitely worn out.

You can see how I replace both my timing chain and oil chain tentioner, pages 16-20 http://www.ferrarichat.com/forum/technical-q-sponsored-algar-ferrari/438576-348-engine-out-major-16.html

 

Here are a couple pictures. the old one on the left , new on right. The new set up in the front cover.

There have been too many folks not understanding the updated tensioner. Glad it helped, good luck with your project, Bryan.

 

How many miles on the engine?

 

Hello

I reply to this topic since I am in the progress of changing my chain pads to my 1989 Mondial T.

I have ordered the tensioner 185577 and I have just read here that in that it won't fit and I would need also the parts 179938 169594 11065474 and 171960 .

Could someone please confirm me that this is correct and by ordering these parts and only these ones the new tensioner will fit to my Mondial T?

Also, I am a bit wondering in order to not mess with it. When I will receive the new tensioner, will it already be charged and ready to by used just by unscrewing the bolt?

Thanks

 

Yes. you need the next 4 parts, and it DOES indeed come pre-tensioned, and you just twist the little bolt head to release. I just finished mine, and forgot the washer and the spring clip.

Great thanks a lot for the quick answer.
Will order them then.

I haven't seen any answer regarding the timing chain pad and the apparently missing plastic tit in the new parts?
Should I use the one I have in my old one?

Ricambi sells the whole thing as a kit. you can see the part numbers and pull up the parts to see the bits. i bought it all from there when i updated 360 tensioners and there was nothing missing.

that's the 360 chain tensioner but also got the square timing chain pad there. no missing plastic.

does it have a hole in the face of the pad for oil to come out? I had a thread around here somewhere...

For the timing chain tensioner I only see the reference 147338 and Ricambi only shows the pad itself. But I don't know if it is supplied with the spring and its kind of socket and plastic tit like shown on the previous link.

I am ordering from Eurospares since not in the US and should get only the pad but I still haven't received it will see but I am wondering what I will do of the plastic tit I should have on mine (the one on this picture):




Yes I think I remember your thread and yes my timing pad has an hole and even new holes..!!

Hi gents. Would these part numbers be the same for a 348? I’m having to go through the same process.

 

Yes...but double check. I did my work on my 348.

what year is yours? check the bearing on the block if it's pre 1991. You're already most of the way there doing a tensioner block.

sjd

 

Thank you. Mines a 1992.
I have done the bearing already and was just reinstalling everything and found the tensioner didn’t fit. I played around and combined the new and old tensioner and got it to work but I’ll just order the 4 parts you mentioned and do it right.
