VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 1929 Timing Cover Removal

Looking to replace the Timing Gear Cover Gasket & Plate Gasket.

What is required to remove the Cover ?? Do you have to remove the Crank Pulley ?? If so how easy is it to remove this pulley ? what about putting it back on ??

Hints, Tips, tricks, are welcomed to make my venture EASIER !!

Check your shop manual. Also, do a search here on Chevy Chatter because we had a great discussion on removing the timing cover and the harmonic balancer recently.

Basically, since the harmonic balancer is in front of the timing cover, the only way to remove the timing cover is to remove the harmonic balancer first.

Hey Skip don't forget to tell him that 29 did not really have a harmonic balancer. It was just an open webbed pulley to run the generator and water pump. It looks just about the same as the 28 pulley but is slightly different in diameter (about 1/4"). The ones I have - have a part number and the number 6 cast in them. Not sure if this is deliberate or merely a coincidence from that particular foundry. I think they started with the true spring loaded dampner sometime in the 1930 production model. The plate behind the cover has the front motor mount attached to the bottom. You will need to support the engine to remove this plate. The oiler for the timing gears is threaded into the inner plate and if disturbed must be carefully re-aimed as directed in the manual. Seems to me - if I remember correctly, there is some interaction with the front main bearing bottom saddle as well with several layers of gaskets acting as shims. I do not believe my engine was ever apart and had three layers of gaskets in that space to make up a difference.

Yes, that is correct....1929 had a crank pulley, which had to be removed before the timing cover could be removed. Also, early 1930 had a crank pulley as well and then later in 1930 the crank pulley was replaced with a harmonic balancer.

I removed my crank pulley with a three armed/hook puller. it came off pretty easy. Right now I'm not sure if I used three holes to grab it or the outer edge, it's been a couple of months

Thought It had to be Pulled off... see it in the 29 Manual on pg 41

Now How about putting it back on ?!!? And does it stop at a specified point or how do you keep all the pulleys (Crank, Fan/ Water Pump, Generator) in line.

Reason Why I Want to remove it:
Another place that an RTV/ Sealant was used to put engine together !!

I would check the pulley very closely, it appears the pulley was bent in the removal.

The RTV sealant was popular about 25 years ago, both by the factory and shop use. That has about all but disappeared today....thank goodness.

It will stop at the correct point when installing.

Thanks Chevgene...

did not know if it had a STOP built in the shaft or would slide until it hit the cover if allowed.

Also will check the Pulley to make sure it is SOUND and not fractured, I did notice the bend, wonder if that was from previous attempt to remove !!

so just put it back on and tap it till it stops or ?!? was thinking of heating it up slightly in an oven then sliding it on the end of the crank.

Thanks JY Dog :)

want to make sure I can put it back on, If I can take it off !!

Ya, I know what you mean. Sometimes a crank pulley or a harmonic balancer can be a real pain to get back on.

Went out and pulled the pulley off, thanks to my neighbor and his collection of pullers. Was a pretty easy job with the right tool, used a 4" 3 jaw puller.

Then removed all the hardware holding the cover on, then gently with a small putty knife worked my way around the edges to break the seal of the RTV... WHAT A PAIN !! Head on Shot

Spent some time cleaning up the cover & the face of the block
Cover Underside
Cover Topside

Anyone Identify this, looks like a seal of the sorts. It spins around
Seal ?!

Also is this the oiler ? Oiler Pict 1?
Oiler Pict 2?

This is a close up of the Timing Gear, Looks like it is pretty new, so figuring it was replaced on the engine overhaul.

Looks like the original timing gear.
If it were mine I would replace it.

I agree ....Seal should not spin I think, so I would replace it as well.

The gear was made by Formica? Ha!
The seal should be held by the timing cover. It might be possible to tighten the hold of the cover on the seal by peening it around the periphery of the seal. Also there chemicals known as "bearing mount" which are routinely used to tighten bearings and races in housings, for example. The first time I saw this years ago, was at the local Caterpillar dealer. It was an official Cat product and it worked for us, to tighten up bearing races in an old D-7. This might help you here.
One question: did your puller pull on the rim of the pulley, or in the three holes in the hub? The manual says the rim is OK but I am a little concerned about breaking my pulley.

The 1929 timing cover did not have a seal. An oil deflector was used on the crankshaft instead and the hole for the crankshaft that is on the timing cover is open.

Looking at the Timing Gear, it Looks Brand New, no nicks, chips, anything...

JyDog is that the Oil Deflector in the Bottom left corner on the shaft in this picture Oiler Deflector ?

The fact that the timing gear has a Bow Tie emblem indicates it was made prior to 1934.

Yes, that is the oil deflector.

Thanks Chevgene
Wow, did not know that, another piece of information to add

Thanks JYDog
Is that copper piece the "Nozzle, Timing Gear Oil"
and does it look correct >!>

Yes, the brass thingy is the oil nozzle and it looks correct.

Thanks...

OK, finally back into the car again, nice weather and some time...

Trying to figure out how to mount/ install the thrower
Thrower, Crankshaft Oil.............835603

Here is how it was mounted/ installed when i removed the cover:
Flinger

is this correct, it has a keyway slot in it. does not seem right.

That is correct. When the pulley (balancer on later models) is installed it will hold the slinger in place.
