Triumph TR6 - Replacing timing cover

I am sure to most this is a "duh" question, but I am having a real hard time getting the timing cover back on. I have the TR6 Cd and it says to put the oil seal on after installing the timing cover. After pulling my timing cover I cleaned it up, put new cotter pins in the tensioner and installed the oil cover in to the seal. It seemed to make sense (I hadn't read the cd instructions) because it looke to be the only way it would fit. I am pulling the tensioner back with a wire to help the fit but can't seem to get it aligned and the seal to fit over the end of the crank. Looking at it, it doesn't seem to make any sense to try to put the seal in after installing the cover because it seats perfectly the way I did it and the way the old one looked. Thanks for any help!

Front oil seal mounts from the inside of the timing cover. Don't forget to position the oil thrower (I forgot the first time!)Once timing cover is positioned you should be able to slide in the oil seal sleeve on the nose of the crank and into the oil seal.

If your engine coolant is drained, you might want to try and remove the two studs underneath the water pump. This will allow you to pivot the timing cover wide to align the tensioner against the chain. (Instead of trying to pull it back with a wire or rod of somesort.)Then pivot the timing cover compressing the tensioner against the chain until you get a few of the bolt holes aligned.

Then you can apply some sealant to threads of the two studs you removed from the block. You can use the two nut method to tighten the studs back into the block.

If you don't have the studs, buy them (big 3) because you will get a glycol leak now that you have cleaned off all the oil and crud. My PO did not use the studs and after I cleaned off everything and put it all back together I could not figure out why I had a glycol leak from behind the bolt. After close examination of the TRF or Moss catalogs I found the studs and ordered them. Leak stopped.

Good Luck! Cheers! MRankin '71 TR6 CC61212L

Bill,

As mentioned, I was able to cock the cover a little to the side enough to get the tensioner to touch the chain and then pushed it back to the center and sliding it into place. I don't remember having to remove the upper studs. If I did I'm sure I used sealer on them because a couple of them go right into the water jacket.

Ok, I'm not feeling real mechanical right now....my son and I tried to get the timing cover on and still couldn't get it to seat. We also managed to tear the gasket, so I need to reorder for next weekend! A couple of questions.
1) Should I fit the gasket to the engine block first so it doesn't tear? His idea, and it makes some sense.
2) I bought the oil seal from TRF that I thought should be placed into the timing cover before installing. Is there another seal that I need. From one of the posts it seems as if there is an oil seal sleeve, and an oil seal. The TR6 cd said I should put the seal in after positioning the timing cover and that didn't make sense because it fits easily inside the timing cover and looks like it did on my cover when I pulled it off.
3) I have everything off the front of the engine so positioning and leverage is not a problem! By the way tried the wire around the tensioner and it helped but still couldn't get it to seat.

Thanks, Bill/Indy

Bill,

Just blame your problems on the snow you guys had last week!

1) Those gaskets are pretty flimsy, you just have to be careful with them. I usually use a thin layer of sealant to hold it in place while fitting everything up.
2) There is one seal, one oil slinger and one oil seal sleeve. If someone/thing is telling you to put the seal in after replacing the cover, they/it are wrong. The seal has to be installed into the inside of the timing cover with the lip facing the engine. The oil seal sleeve can be installed after the cover with new seal is installed. Actually that is the best way to do it.
3) There is really nothing, aside from the tensioner, that should be getting in the way.

Are you trying to install the cover over the shaft with the oil seal sleeve in place?

Is the oil slinger fitted up next to the crank sprocket?

Really dumb question, is the free end of the tensioner facing up?

Good Luck,

Don

Thanks for the info Don! As far as a "dumb question" re: the tensioner facing up, with the way this little project has been going it is quite appropriate! Would you be able to drop me an email so I can email back a pic of what I am looking at? Also, wasn't quite sure if I was to attach the gasket to the engine first or to the cover? I am ordering 2 gaskets this time!

Thanks, Bill
