Cleaning Up Cam Bearings After Installation

Once in a while you may get an engine block that has an imperfect or misaligned cam bore. Rather than taking the time to scrape the newly installed cam bearings to fit by hand I took old cam cores and made cutter cams. Verifying the cores are straight, I milled slots across the journal at an angle (deeper on one side) forming a cutting edge. You can then install the cam core and rotate it scraping away any tight spots and minor misalignments. It works great for me.

Bringing ‘Lean’ To The Small Shop

Lean applies to every function within a business whether large or small. Your customers don’t care if your success/failure comes from you practicing or not practicing lean in your shop – however, you will see the benefits in more business and greater profits.

The fundamentals of lean are:

Plan, Do,Check and Act.

• Step one should be selling the idea of lean to your employees – but with actions not words. You must demonstrate to your employees that lean is worth the effort by teaching the fundamentals.

• Allow employees to test out new ideas and techniques. They can establish a common means by which to experiment, and ultimately to share best practices/procedures.

• Take waste out of processes that are unnecessary. Anything that frees up time and/or reduces unnecessary inventory and spending will be immediately recognized.

• Establish agreement with the customer on both what needs to be done and how to accomplish it.

• When communicating and negotiating with a customer, most shop owners/sales professionals focus on getting agreement on the what – product, service, price, timing is involved. The how is left to the existing process. But many complaints, gaps and disagreements come from lack of agreement on how methods, communications, and decision making processes are accomplished. Learning to establish the critical how’s early can lead to better long term customer satisfaction.

• There are many good books and articles on Lean that can be seen or purchased on the internet – one is The Hitchhiker’s Guide to Lean: Lessons from the Road.

Stubborn Dowel Pins

Some solid dowel pins in cylinder heads, blocks or flywheels, especially those that have been removed before, can be difficult to get a dowel pin puller jaws to grab a hold of. I use valve lapping compound in the jaws. This acts like “teeth” for the jaw surface and can give you that additional grip you need to remove the stubborn ones.

Removing Stubborn Pressed-In Rocker Studs

This is how we remove a pressed-in rocker stud that refuses to pull out, especially those that have been through a bake oven. If the stud has broken at the threads, thread the stud and then use a poly-lock as a drill guide bushing. After drilling all the way through the stud the wall of the stud should have collapsed enough to tap and then continue with a puller or continue drilling out larger to either peel the remaining part of the stud out or just drill it out.

Cleaning Damaged Threads and Splines

When trying to use a thread repair file it takes forever to clean up damaged threads. If you first apply valve grinding compound to the threads, then use the thread file it can be done in a fraction of the time. This same practice can be used for buggered up splines. Take a three sided file and cut the end off (where there are no teeth), apply valve grinding compound to the splines to be repaired. Now the file will do the job with ease in no time.

Keep Your Serdi/Newen Style Cutters Cool

Would you like to get more life out of your Serdi/Newen style cutters on hard or Abrasive valve seats? Spray them with alcohol. I have some old methanol from our old funny car, I put it a spray bottle and squirt my cutters. I have found some finish improvement and longer life from the cutters. It works especially well on large radius bits or bowl hogs.

Inventory Etiquette: Pretend It’s YOUR?Part

Today’s totally tired subject matter has to do with what I call inventory etiquette. My definition of inventory etiquette is to treat any parts you handle as though they came from your own shelf and not the shelf at the local parts house. Basically, when you’re ready to pick up that $200 head set with two inches of grease on your hands and then pry it open with a pitch-fork, pretend it’s yours and that there is nowhere you can return it. The bottom line is to make sure the parts are correct, then, by all means, torture them any way you like. I know this advice is elementary, but, tell that to the guy who just walked out of your shop with the sad face and the gouged open, wrong, $200 headset in his hands.
