Crankshaft timing gear removal.
1 Attachment(s)
Does anyone have a brilliant idea for removing the crankshaft timing gear. You can see in the photo that it's spun on the crankshaft and sheared off the alignment pin. (Yes, it was a killer dowel pin that caused this!!!)
Attachment 34664 There's about a 1/8" to 3/16" space between the gear and the front of the block. Is there a Cummins tool for this? Here's a link to a similar tool a guy built to pull a BMW gear. I'm not going to pay a machine shop to build one but if anyone has already made one I'd be willing to pay to borrow it. http://www.isettadoc.com/files/gearpuller1.pdf I'm going to pull this engine so if necessary I'll remove the crank and have a shop pull it off and press it back on with a new alignment pin. |
you should be able to put a welding glove over the gear and use a big pipe wrench and spin it back. you should be able to pull it off with a reg gear puller. that's how I have done them.

Good idea using the leather over the gear.
I still can't get the puller onto the gear because there's not enough space between the gear and the block. I'll experiment grinding down the puller jaws to get it behind the gear. |
use a punch and 4 lb sledge ... then buy a new gear ..

Are you saying use a punch to break the gear off the shaft? Or will the gear spin off? Or a combination of turning and breaking it off?

I looked at the pics and it looks like if you used a punch and hamme it would re-allign with the key and then yo ucould heat with a torch ( Carefully not to heat crank much ) and carefully use a set of bars to work off ..... of course having all the right tools has never happened to me so this is back woods engineering from my head ... i have done a few engines like this .... I also have used a die grinder and carefully cut through the gear and the drove a small hardened chizzel into the gear to help seperate it a bit .... worked ok ... gonna take patients, and a level head my friend ... if you get pissed off ... take a break .... I know how hard they can be .... keep posted ... i'm watching :pca1:

I'm sort of a back-woods mechanic so I understand exactly what you're talking about. I pulled the KDP killed engine this weekend so I will begin working on it once I get my "New" engine installed. It's going to be several weeks before I get to it but I'll post here once I determine the solution.

ok ... kew l ... look forward to it being a fun time... LOL
