View Full Version : Prevent engine turning, Bad Cam Gear Update

Hi All,

About 1954 Champion, 170 6 cylinder engine.

After the Mississippi Valley Zone Meet last weekend, where I went Studebakerless, because my fiber timing gear has stripped I am back at fixing the problem.

I had a parts engine to get a nice gear out of and could chain the flywheel to prevent the engine from turning when I removed the crankshaft bolt to get the gear.

Tonight I've got the radiator out and access to the engine but the crankshaft bolt just turns the engine. Having the transmission engaged does not help; it just turns. My engine is older and loose.

Short of pulling the starter pff and using something to jam the flywheel are there any suggestions on how to hold the engine still so i can remove the crankshaft pulley. Also, I'll have to use any suggested method to put it back on at 130 lbs torque.

I have read about the special tool offered for rent by Chuck Collins for installing crankshaft & cam gears. Is that tool really critical for this process and engine? My engine is old and loose. I think the gear will go on easily.

Lastly, because my gear is stripped do i need to have the engine at TDC on #1 for this gear install. I can line up the dot marks because it seems the gears only goes on one way with the keys. Do i have to watch for anything special. This seems like an easy repair but as usual I'm uncertain about what not to do.

All tips and comments appreciated.

Use a air impact, it'll spin right off.

Ditto what John said but, I suspect you're doing this under a maple tree in the back yard.:D
There are battery powered impact guns that work very well, if you can find a mechanic who has one.
Short of filling two cylinders with oil to produce hydrolock, someone here should have a simple suggestion.

I believe if it's not at TDC on #1, you may get it off by 180 degrees.

What Brad said. The No. 1 TDC mark on the balancer is also for No. 6, and you have a 50% chance of getting either one. It doesn't look like the last four cylinders (6-5-7-2) match the first four, (1-8-4-3) so the valves won't be in sequence. You will have to put No 1 at top center, the mark on the crank goes around twice for each rev of the cam.

Take out a spark plug and stuff two feet of soft nylon rope into the cylinder and turn the piston up to it to stop rotation.

Just be sure to leave a piece of the rope sticking out. ;)

I don't know how much room you've got, but if you don't have an impact (and there's room), put a box-end wrench on the bolt, hold it on there with your thumb, and smack the other end of the wrench with a heavy hammer in the direction of lossening. Works pretty well!

Don't forget to drop the oil pan to dump out all of the stripped off teeth, and clean the oil pump pick up screen reel good.:) Hopefully none of the debris made it any further than the screen. Hope this helps.:)

I might have dreamed it, but a long while back I believe I used a break over bar with a cheater bar against the frame and hit the starter. It might have been on some other type of engine.

Another trick I've used on crankshaft nuts in a pinch is to jam breaker bar and socket against side and bump starter, if you can get against
some thing that won't get damaged. May have to have some one hold it in place while you quickly bump it. Space limitations may prevent this on
some cars.

Broken fiber gear, leads me to wonder if you have a crank or cam thrust issue. I would be sure and check that before you put her back together. Hope this helps.

Hi All,

JDP: Using an air impact did the trick. Engine never even tried to rotate. Bolt came right off - THANKS!

Rockne10: Yep on my farm and under the shade of the "old windmill".

Tom B: It's a 6 cylinder, not an 8 so I can easily rotate it to TDC on No 1. Rope trick not needed - Appreciate the future tip.

Bams50: Lots of room with the radiator removed and it being a 6 cylinder. If there was less of me i could climb right in ;)

Roadraceclark: Good tip. Found most of the stuff around the gear. But i will scope the oil pan and look for debris there too.

The fiber camshaft gear was well worn after 50+ years. I have it apart and ready to reassemble so that will be the fun job this weekend. THANKS TO ALL for tips & tricks. Pics of the destroyed gear:

The air impact trick works on generators and alternator nuts too, but they do spin up a bit.:)

That works on Volkswagens to bust the crank nut loose, for sure.

Hi Henry.
I need some help, Can you tell me what you used and how you removed the crankshaft pulley?

Thanx

I normally use my K-D steering wheel puller to pull the cam and crank gears. (Can see a pic here:http://www.sears.com/shc/s/p_10153_12605_00999055000P?vName=Tools&cName=MechanicsTools&sName=Automotive%20Specialty%20Tools&psid=FROOGLE01&sid=IDx20070921x00003a)

Works well, just make sure you protect the end of the camshaft and/or the end of the crankshaft by using some washers and a little never-seize.
