In a pinch, I have used a chisel to break the gear off. The body of the gear is made of composite material, but the centre of the gear is metal where it presses onto the cam. If you break the composite part off, you can use a chisel to remove the metal centre. Don't hit too hard as you may damage the cam. If you can carefully heat up the steel centre part, it may help to remove it.

In order to replace the cam gear, you have to take it to a machine shop and have it pressed on and off.

How to change a timing chain on a fuel injected v8


Same as any other v-8 dis-assemble the front of the engine to get to the timing cover. Loosen the oil pan bolts to allow the timing cover to be slipped out. unbolt and remove the timing cover. Turn the engine over by hand until the dot on the crankshaft gear( the small one) is at the top 12 oclock position, and the dot on the cam gear(large gear) is at the bottom 6 oclock position remove the old cam gear and old chain. Install new gear and chain with the marks in the same places. Re assemble engine. DO NOT be tempted to just put in a new chain, replace the chain and cam gear as a set, wear on the cam gear will cause the chain to be slack, which in turn causes the cam timing to be late.

1985 fiero been having problems getting in gear. Now wont turn over starter. New starter didnt fix problem. Dont know if 2 problems are related. Can push start.


Have same car, same problems, easy solutions.

Getting into gear has been improved by putting in neutral with engine running to warm up fluid. The Fiero has very little room in the pedal area. I'm shifting a lot better with smaller shoes.

The problem with starting may well be related to the same issue. There is a neutral safety starting switch. If you're not pressing hard enough on the clutch - starter won't run. According to the Fierostore.com stock clutch pedals tend to bend. They sell a stronger replacement.

My Fiero has been starting just fine the last few days. The last time it didn't I was wearing boots.

I've almost always been able to get it to start using a booster battery, but Walmart's tester indicates that the battery and charging system are fine. It recommends tightening connections. I did this, but still had problems for a while.

Cam shaft gear sprocket part missing that reads cam censor. Need to get this, where can we get it? Is this a maganet.


Yes it is. The timing cover must come off to repair this. While you are in there if its a 3800 replace the chain and tensioner. If it's 3.8 replace the two gears and chain. Along with the magnet as it goes on from the back side of the cam gear on both. Any dealer or auto parts store.

I need a diagram to sincronize the timing belt of my isuzu tropper 3.2 sohc


if this is 6VD1 engine it has single cam gear each head, but is still a 2 cams per head, engine
if belt has broke or you have turned any gear you must remove rocker covers to check positions of camshafts front lobes are in certain spot as well as timming mark on belt driven cam gear to cover
this cam gear is a 3:1 ratio (3 turns of cam gear = 1 turn of cams)
