Model B Engine Further Strip down

Model B Engine Further Strip down


Now Christmas is out of the way it was time to take a trip over to carry on with the strip down of the Model B engine.

The engine has been soaking for quite some time and unfortunately is still stuck, so we got to work looking for the source of the problem

Upon removing the main and big end caps things were starting to look quite promising, however as we got to the rear main….

We found that the babbit had broken up quite badly and as a result would have been very noisy in operation. The white metal has been done previously in a non Ford type manner but this doesn’t appear to be the cause of the failure. Either way the engine needs a complete re-metalling as there is also a cracked big end.

On the upside the counterbalanced crank appears to be in pretty good shape.

Back to the task in hand and we found the source of the seizure, number one piston is stuck in the bore. We gave it a few gentle taps but it remains stuck. So we’ll be soaking the bore for a while and we’ll get back to it in due course. The bores look good so it would appear that it’s most likely carbon and a lack of movement causing the issue.

Next task is to investigate the re-metalling.



Model A Sump/Oil Pan Clean Out


In the UK we call it a “sump” in the US it’s called an “oil pan” whatever you want to call it I removed it today to give it a clean out. It’s not as sludged up as I feared it might be especially as the oil looked horrendous as I was draining it out. Another added bonus was the lack of any noticeable metal filings in the drain bowl. As most people know the Model A Ford has a pump assisted splash engine lubrication system for want of a better description, plus the Model A was born in the days before detergent oils meaning that the sludge would build up in the engine over time causing a lack of lubrication and probable engine damage. My oil pan has about 2 inches of sludge in the the bottom of the pan, plus some residual sludge in the crankcase. With the oil pan removed you can get a view of the crank &  cam shafts, which is of particular interest as I have a bit of an engine knock on cold start. Hopefully we are not looking at mains or big ends as the has babbitt style bearings. Next steps will be clean the pan & crankcase before removing all the old gasket material prior to refitting the pan. For part of the job I used a Ford spanner given to me by my Dad about 35 years ago!
