The Triumph Dolomite Club - Discussion Forum

Hi,
Sorry to bring up the subject yet again, but.....
I need your input here please.
On the advice of several folk on this forum I bought a genuine Jaguar tensioner to replace the defective Rolon rubbish I recently installed in my Sprint.
Now, all the holes line up nicely, the rubber pad's ramp is the same profile and it looks like it'll just bolt up fine. I am however, concerned about the size of the oil inlet hole in the side of the thing.
The Rolon has a pinhole size inlet, but the Jaguar item is a huge 8mm in comparison.
Will this cause me a problem? Lower oil pressure, or will the extra oil capacity of the item be an advantage.
Cheers,
Rob

FYI.
Like the French made Renold I was trying to buy, this genuine Jaguar one is also made in France.
Cheers,
Rob

Ultimately the smallest hole is the biggest restriction so in the block face that the tensioner bolts to,that hole will be all it can give. A larger hole after that (in the tensioner body in this case) wont lose or create any pressure. The extra volume in the tensioner may simply add a "puddle) in there to keep a good supply of lube to leach out when pressure is low.

Beauty!
Thanks Tony.

Yes the only thing I would add.
Check the back plate to ensure the oil gets to that hole, as one plate that I have seen had no hole!

Its probably a good idea to run the car for a few thousand miles to generate those shallow chain grooves and then take the timing cover off and reset the tensioner so its not out too far.
I hasten to add this is just my idea and I can be wrong but I did it on my Stag and despite doing hillclimbs, sprints and track days I never had any engine problems. (I was younger then and drove like I stole it )
