Found, it. It was someone else, this was on Latus HD web site.

hey there, I am planning on having a large displacement 113" - 124" motor built for my 2007 FXDB. I am hoping to run about 120- 140 hp/ft-lbs range. I have been hearing though that welding my crank pin is a good idea. What are your thoughts? THX

We recommend it but has to be done by someone who knows how to do it correctly. Recommend sending the entire crankshaft assy to Hoban Bros for balancing and welding to get a bullet proof crank.

We too use Hoban to do our crank work. If the pro plug is done they will tell you that welding is not a item that is needed for the tq numbers you are running. You can have it welded if you want,... but if you every have to repair the crank you can have problems due to the pin being welded, kind of a double edged sword. We use the pro plug from hobans in the cranks and even keep some cranks on hand for exchange for the standard street builds. They have held in builds making more than that with no slippage issues thus far. We like there work and they take care to ensure the crank is set up correctly.

Just thought I'd pass this on.

If you have your motor built at Latus don't let anyone but Mike Stegmann do the work. And make sure to have a consult with him before hand. Very kind man to talk and deal with.

The more I thought about this topic, caused me to have more questions about the process and exactly what was being done.   Called Jim's directly today and spoke to Eric to find out more information on the Crank Welding that was to be done, apparently their processes were refined with the help of Hoban (Darkhorse).   So the Crank I was having welded and trued etc is actually pin welded / balanced and trued and not just welded.

As long as we are considering random thoughts; if you can shrink a bearing race with your welder in order to remove it without a puller, what happens to the interference fit between the crankpin and the flywheel when you weld the assembly?
