-=48Chief=-: Balance Factor
http://48chief.blogspot.com/2013/06/balance-factor.html
Monday, June 24, 2013. Blog readers will know I am working on understanding balancing crank assemblies. This was stolen shamelessly from Jockey Journal. Seems like a 60% balance factor keeps coming up. S&S supposedly uses 60%, and Paul Osborn (from Truett and Osborn) told me he uses 60% unless the customer specifies otherwise. September 29, 2013 at 8:19 PM. For those keeping track, ultimately I used a balance factor of 64%. Yes, final answer. Subscribe to: Post Comments (Atom). GREER - 48 CHIEF CATALOG.

Sunday, February 24, 2013. Like so many aspects of old motorcycle restoration, painting the inside of the cases with Glyptal seems to elicit polarized opinions. Among the purported benefits: sealing porous cases, facilitating oil drainage, and encapsulating any remaining contaminants (e.g. residual glass beads). So say the advocates. I took the plunge. Watch this space to see how it turns out. Friday, February 22, 2013. Polishing the pinion shaft. Went with Bitmonkey to the Early Bird Swap Meet last week...

Sunday, September 29, 2013. Many aspects of the engine rebuild have been intimidating, but none so much as the equally black arts of balancing and truing the crank. I hired out the balancing to Truett and Osborn. They have been in business since 1974 or so. I am confident they have figured it out by now. The work looks very thorough. Time will tell. For the truing, I relied on the expertise of Fuzzy Jamison, owner of Classic Thunder. Watching someone beat on your immaculate flywheels is like watching an ...

Wednesday, May 29, 2013. Well, I have come to a momentous decision. Because of my flywheel troubles (see previous post), it was recommended to me that I would be better off replacing the old flywheels with new ones. Since the primary cost of upgrading from 74 cubic inches to 80 cubic inches is the flywheels, this caused some serious reflection. 1) Replace the flywheels. 2) Shorten the piston skirts 1/4 inch to keep them from hitting the case at BDC. This is my stock 74" head. note the lower part of t...

Monday, April 15, 2013. Shhh Don't tell Lynn. The other day, Bitmonkey posted a picture of a 1938 Briggs and Stratton WMI 1/2 hp engine that followed me home from the Twinline motorcycle swap meet. These were used on washing machines and mowers. Don't ask me why, I am a sucker for a project, and it's so cute and needed a home and we all know '38 was a good year for flathead engines. So I found tins on eBay for the '38 after all. Subscribe to: Posts (Atom). GREER - 48 CHIEF CATALOG. 1948 INDIAN SUPER CHIEF.

Pictures and video of the new Indian engine have just been released. This has to be the first time the styling department asks engineering to make an OHV look like a flathead! See it run here.

Friday, December 21, 2012. More cracks for Chris. A thorough cleaning and inspection of the transmission case revealed some more cracking:. Fortunately, this is the only primary attachment bolt that actually threads into the transmission case. The rest simply pass through and have a nut and washer on the back. To add insult to injury, there is a piece of broken bolt imbedded in that hole. Case Repair - Magic! There is actually a companion crack underneath thats not visible in this photo. To do the repair.

Monday, October 7, 2013. Relieving the cases for 80". When I discovered I needed to replace the flywheels I decided to go from 74" to 80" displacement. This involves several small operations, most notably buying flywheels with a 3/8" increase in stroke. As mentioned in previous posts, the piston skirts needed to be shortened by about 0.250" and the heads had to be milled to clear the pistons at TDC. Once we got the right case half relieved, we simply relieved the left case half to match.

-=48Chief=-: Progress!
http://48chief.blogspot.com/2013/11/progress.html
Thursday, November 7, 2013. I have spent so much time dreaming about the day when my Chief bottom end was finally put together for the final time. Well, it's here! This first picture shows the cams in and correctly timed:. This next picture shows the new pushrods, and also illustrates a problem. I had too little clearance even with the adjusters bottomed. I called a fellow Indian afficionado who has already saved my bacon once! He asked me if I had the "thick" or the "thin" lock nuts.
