PhilW Posted February 9, 2015 Report Share Posted February 9, 2015 Hey guys. I'm new to the forum and glad to be here. I've got a 49 Plymouth with a 218. I'm replacing the timing chain and was wondering if there was work around on reinstalling the crankshaft gear and crank hub. The manual refers to a C-522 which I'm sure is impossible to find. Thanks Quote Link to comment Share on other sites More sharing options...

PhilW Posted February 9, 2015 Author Report Share Posted February 9, 2015 Thanks, but how do I install the crankshaft sprocket on which the timing chain sits. I haven't got it off yet but the kit I bought included both the cam and crankshaft sprockets and the chain was really stretched so I think that both need to be replaced. Would I just slip the new sprocket on and then then gently tap into place using something a little bigger in circumference than the crankshaft? Thanks!

Dodgeb4ya Posted February 9, 2015 Report Share Posted February 9, 2015 You will need at least a 2 jaw gear puller to remove the crank gear.. They are on tight I use either 2 or 3 jaw posi-lok pullers when removing these type of crank gears. To install the gear back on the crank snout I use a special threaded installation tool that pushes the gear back on the crank. I suppose you could bang it on with a steel tube or big deep socket ....I wouldn't.. thats hard on the crank thrust bearing surface.

Dave72dt Posted February 9, 2015 Report Share Posted February 9, 2015 Posi locks are nice and work well but I've never found them at a tool rental and they're pretty pricey for a one time application. You may need to head to your local machinist for removal and installation. Quote Link to comment Share on other sites More sharing options...
PhilW Posted February 9, 2015 Author Report Share Posted February 9, 2015 Thanks Bob, these are great pictures. This is extremely helpful. Where would I be able to get a C-49 installation tool? Also, is that a large round cap bolt inserted in the crank snout that the puller is pushing against? Thanks so much! Phil Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted February 9, 2015 Report Share Posted February 9, 2015 I made my install tool years ago. Quote Link to comment Share on other sites More sharing options...
ROB-PA Posted February 10, 2015 Report Share Posted February 10, 2015 In my previous life I removed and installed many timing gears from VW crankshafts. The 3 jaw puller will work well, just be careful not to damage the teeth. A little heat on the gear and lube on the interface just prior to the pull will help a lot. I actually had my brother, who was a machinist, make me a special fixture for the gear removal. It uses a machined plate that provided about 180 degree contact behind the gear in place of the 3 jaws. Installation is much easier. I just heated the gear in an oil bath on the stove to about 300 degrees F and it slides right on. You may want to keep some tension on it as it cools to prevent it from pulling back off of the shoulder. When I did the VW set up the crank was out and was sitting vertical so there was no issue.

PhilW Posted February 14, 2015 Author Report Share Posted February 14, 2015 Rob Just wanted to let you the oil bath for the crank gear worked like a charm. Thanks so much for the advice! Phil Quote Link to comment Share on other sites More sharing options...
