This is the best video I found online for the timing system replacement for my GM Gen 3 293/294 small block V8 engine. It also includes other LS engine displacements. Cloyes rep is very detailed, provides great step by step instructions, bolt torque specs and it is done very professionally. Thank You Cloyes!

@foxlyfe5175 4 года назад

Good information thank you

@shadowcast1975 2 года назад

great vid, just curous on your opinion in shiming the oil pump gear before torqing the bolts

@Ventyv 3 года назад

I’m building a gen 4 ls. I installed the hex adjust double roller timing chain. The cam sprocket is grazing the camshaft position sensor. What would be the best course of action?

@Cloyes01 3 года назад

You will need to grind away the section of the cam sensor that is in interference.

@donald5162 Год назад

I thought the cam sprocket bolts are TTY? Doing this on my 09 suburban next week.

@derrickmorrow7662 3 года назад

So just to clarify, on 3 bolt sprocket. Torque to 26ft lbs. no degree turn just 26ft lbs? Also would it be a good idea to use red loctite on the threads for the cam sprocket bolts?

@Cloyes01 3 года назад

Correct, just 26 foot pounds. And yes, some thread locker on the bolts would be a good idea.

@93paxon 5 лет назад

Hoping I can get a little help from you guys. I just tried doing this install and stupidly installed the new sprocket on the crankshaft with a hammer even though the video says not to. I just hard a serious brain fart. Anyway, now I can't get the camshaft sprocket and chain to fit. Did I seriously fuck up something? I noticed when I was putting on the new crank sprocket that the crankshaft key was moving a bit.

@Cloyes01 5 лет назад

Installing with a hammer should have caused any problems unless you damaged a sprocket tooth. Does it seem like the chain is too tight? Can you just not get the cam sprocket to lip up onto the camshaft?

@93paxon 5 лет назад

Cloyes Gear & Products, Inc. yes the chain is so tight I can’t put the gear on. I even tried reinstalling my old set and it’s now too tight to install as well

@Cloyes01 5 лет назад

@@93paxon I would recommend pulling the crank sprocket back slightly to attempt to install the chain and cam sprocket. Once you get the cam sprocket indexed onto the cam you can press the sprocket the rest of the way on.

@MOE13576 9 месяцев назад

What about finding top dead center on piston 1 when aligning the timing chain ?

@Cloyes01 9 месяцев назад

When the sprocket timing marks are aligned in the middle, as we show, that is going to position the engine at TDC #1.

@javierespinoza6551 4 года назад

What's the part number for the jaw puller?

@orion1588 2 года назад

It's generic, so you can get a set at harbour freight tools.

@johndoe-oh4sd 2 года назад

My timing is off by one tooth, how do I adjust it so it’s lined up?

@Cloyes01 2 года назад

I would rotate the engine until the camshaft sprocket mark is at 6 o'clock, then remove the camshaft sprocket, move the crankshaft slightly so the marks will align, then reinstall.

@kevinwest3689 3 года назад

I see alot of ls cam upgrade videos and none are advancing or retarding the cam timing with timing chain. Should I leave my hi price adjustable timing chain at 0 because it's already built into the cam.

@Cloyes01 3 года назад

If you don't plan on degreeing in the camshaft then yes, leave it at the factory setting. Like you said, most cam manufacturers have advance built in.

@kevinwest3689 3 года назад

@brandonrehak9776 2 года назад

what if i have a little slack in timing chain? should it be tight?

@Cloyes01 2 года назад

Factory sets and OE replacement sets will typically have a little slack. Our High Performance sets will fit absolutely tight on a stock block because we use an oversized crankshaft sprocket and hand-match the sets.

@ericbrandt829 2 года назад

@@Cloyes01 ......Seems like the aluminum block motors should have some slack but, iron block should be tighter? I have a 2010 LS3 Dry Sump motor from a Corvette Grand Sport and it has terrible timing chain slack with the Melling replacement timing set....Same timing chain set as the LS7 motor of the Z06.....It has over 1/4" of side to side movement in the chain between the timing sprockets....I'm afraid to run this set.

@Cloyes01 2 года назад

@@ericbrandt829 OEM GM timing sets typically had 1/4" to 3/8" of chain deflection from the factory. Unless you go to a matched performance set with an oversized crankshaft sprocket you are going to see some deflection.
