TU Timing belt 995cc

Recommended Posts

Hi all, 

 

Just looking some advice on replacing my timing belt and water pump on my 1990 995cc. I'm new to Peugeots and have had a look through the Haynes book but is there anything I should look out for while I'm at it. 

 

I keep seeing some stuff about the tensioner setting, something about a specialist tool? Can I just go 90 degrees with an Allen key and torque up the tensioner bolt??

Of course you can .. people have been doing timing belts for ages like so , not only on PSA cars . No special tools needed really .

 

Lock the flywheel and camshaft pulley , fit the belt , apply tension to the belt until the belt can be twisted with fingers sideways at 45-90deg. in the middle on the longest side up front (between crankshaft and camshaft pulley)

 

I prefer to fit the belt and do it at around 45deg , as till stretch a bit over time ...

 

If you don't want to bother with locking the pulleys , use tippex and make a few marks on the pulleys-to-engine and on the old belt , then use those for reference when fitting new belt ... 

Tippex is you're "best friend" when doing timing belts , even if you're locking the pulleys flywheel etc. , use tippex to be double sure that everything is aligned as it supposed to be . 

When done , always spin the engine by hand few times to verify that there's no locking/binding (remove the spark plugs , it'll be easier to turn the engine by hand) .

 

Also i'd recommend replacing complete - belt , tensioner and water pump ...

 

One important thing with TU's - apply some medium thread lock compound on the belt tensioner stud , fit the nut and tight it (after you've adjusted the belt "by feel/deflection") ... as the nut which holds the belt tensioner on TU's had habit loosening off , and guess what happens then !

 

It's quick and easy engine to do timing belts , so no worries .
