Re: Timing Gear Help/Pictures
The oil slinger is missing on the front of the crank gear.

Re: Timing Gear Help/Pictures
I have seen a number of those fiber timing gears that have the metal insert in the center separate where the fiber joins the metal.

Re: Timing Gear Help/Pictures
This is the type of timing gear Tom is referring to.

Re: Timing Gear Help/Pictures
Well, from what can be seen in pics, gear looks to be usable, DEPENDING !
If you put a lot of use on engine and/or higher speeds, IMO, it would be foolish for anyone to do all the work that has to be done to get to where you sit , and not put a metal cam gear on..at least aluminum. But, that is you call,eh Do you have a clue how many years that fiber gear has been in use on this engine ? The longer the time, the percentage goes up for its life end..because of basic make up..i.e.-fiber. From what is shown (beating evidence on nut) , I'd say that it was worked on at some time..but how long ago ? And, speaking of this type (original) nut. Does beating on engine parts with a hammer/chisel sound good/reasonable to anyone ? How about proper torqueing with this type nut. Just like better gears made now, hex nuts are made specifically for this use and can be torqued with proper torque wrench and taken off easily...no BFH (bigger fat hammer) nor cold chisel needed A suggestion is to contact Dan McEachern...the gear master for replacement gears ! |

Re: Timing Gear Help/Pictures
It looks good to me but like one of the guys said, while you have it apart is the time to put one in. I doubt that anyone ever put a torque wrench on any of these cars until recent decades, it is just the way it was done, look at all the tools that were included with the cars including a head nut wrench!

Re: Timing Gear Help/Pictures
My nut showed the same marks when I had to replace my gear. I used the same method as used many moons ago (assumed) that was used on this nut to get it off and back on. If I had more time and patience I would have ordered a new nut with the hex nut end so next time it would come off easer. But decide for yourself if you want to replace nut and maybe the gear. Looks to me like things in this area are in reasonable shape but I am no expert on this subject.

Re: Timing Gear Help/Pictures
Don't worry about the little Knicks on the cam nut.. Just buy the proper tool from one of the jobbers to remove and reinstall it.. Your gear looks fine but since your there you may as well replace it and get a new plunger and spring. You could have just removed the little two bolt side cover to inspect the gear teeth... At that point I would have put it back together.
Your call on the type of cam gear, I would go back with a fiber and not risk a whine or metal filings.... |

Re: Timing Gear Help/Pictures
The gears look good. You should measure the mesh between the cam/crank gears and replace if it is excessive only. The product you purchase to use as a replacement might be better OR worse than what you are showing.

Re: Timing Gear Help/Pictures
I agree you should change it while you have it opened up. I would think that after 15 years it could become brittle and start to break up. You will need the correct socket tool to remove the cam nut. Perhaps some one in a Model A Club nearby would have one to borrow. I have found it is best to clamp the timing gear using two 1/2" blocks (one on each side of the cam gear) and two C-clamps. The blocks will rest on the pan holding the cam gear still when removing the cam nut. I found an impact driver works best on the really tight cam nuts. You can also use the clamp method to hold the cam gear still when installing your new cam gear. The blocks will then rest on the block portion of the timing gear housing. Les Andrews red book calls for 100 ft. lbs. of torque on the cam nut. Good Luck.

Re: Timing Gear Help/Pictures
It's not a big deal to change a timing gear - even on the side of the road. I'd hate to have to walk as far as that timing gear will take you.

Re: Timing Gear Help/Pictures
Both gears are toast.
The crank gear shows pitting. The cam gear shows deep grooving. As noted before, the slinger is missing on the crank snout. The proper tool to remove the stock cam gear nut is available from several sources as is the hex nut if you want to go that way. Contrary to what some people say, metal gears are NOT noisy if installed in sets with proper clearance. |

Re: Timing Gear Help/Pictures
Loosen the 2 hose clamps on the lower water pipe and turn it so the drain cock is pointing straight down. This will also align the pipe better to the radiator outlet.
Your 2 piece pulley and oil pan would need to be removed to install the missing oil singer. If it wasn't leaking oil out the front, and if the pulley is tight, I'd not worry about the slinger at this time. Your pulley is quite rusty, and this will chew up your V belt. You could remove the pulley fairly easily since it's a 2 piece unit, then sandblast it and polish the V with a lathe. Another way to polish it would be to assemble the cover and run the engine with the belt off (coolant in) and use a dowel tapered to a wedge with emery cloth taped to the wedge. Press the emery to the sides of the V to polish the sides. In the late 70's I had a snowmobile clutch with a rusty pulley that wore out a new $30 belt in 2 miles. |
