Electrical gurus please chime in. I bought a recently rebuilt 2-brush generator and set it up on my engine test stand to check it out (after polarizing per the usual procedure). It didn't appear to be charging so I brought it in to a local shop for testing. They called a while ago to say it...

I'm trying, without much luck so far, to get a sensible tachometer reading on a '39 Merc 239 running on a test stand. It has a Bubba-built crab distributor with points and a Bosch blue (internal resistor) coil. The plug wires are solid core. Am on my second tach - currently an Equus Performance...

I’m stumped & could use some ideas on where to turn (no pun intended). Was in the middle of assembly of my ‘39 Merc block, bored .060” over and crank main & rod journals machined .010” under. I installed the cam and crank and the latter turned fine in the new bearings. I installed the valves &...

Looking for advice/tips on how to best install the timing gear on the crankshaft with the least difficulty or risk of damage to the crank (or gear, for that matter). Any thoughts? e.g. heat the gear first, use antiseize, type of drift, etc. Thanks in advance for sharing your expertise!

Hi all. Embarking on my first flathead rebuild ('39 Merc 239 c.i.) and need to know whether the large hole goes up or down on the front cam bearing. I'm aware that it must go up on the rear bearing. I found instructions in a Lincoln Mercury Overhaul Manual (for the 3rd gen engines) that said...

Looking for advice... I bought a triple carb Edelbrock manifold for my '39 Merc block but there is no takeoff (tapped hole) for the vacuum source I'll need for the crab distributor I plan to use. The Edelbrock website's picture of this part depicts two such holes (on the front and rear carb...

Looking for ideas on a lighting problem with my '30 Std Roadster. I recently rebuilt the steering gear and replaced the light switch while at it. Now, regardless of where I put the lever on the steering wheel (in the parking, low or high beam position), all three filaments come on on both...

Finished wiring up a new turn signal switch (VSM 900 from one of the major reputable suppliers) for my '30 Roadster recently - but only after some effort to find a short circuit that would cause the fuse to blow whenever power was supplied to the circuit. It turned out to be a short inside the...

I'm in the middle of replacing the worm gear on the steering shaft and appear to have "run into a brick wall". I've followed the guidelines in the Diablo A's DVD and tapped the inside of the shaft to accept a threaded rod in order to push the new worm gear on using an air impact gun (at about...

I'm in the process of rebuilding a 1939 Merc engine (Canadian keystone block) and thought I'd seek the Barn's collective advice on my rod big end dimensions. Six of the rod big ends measure at the top end of the spec (2.3597-2.3603") but two are outside, i.e one that is .003" fat (but still...

I received an order for 2 water pump rebuild kits today (from one of the usual suppliers - but not Macs´!). These are for the 37´- 48´ style pump. Well, I found that both kits are missing the lock ring that fits in the groove in the end of the impeller (necessary to hold the seal assembly in...

Has anyone seen this type of water pump inlet before and know its history & applications? Instead of a full length 'spigot' for the inlet hose to attach to there is a shallow (~1/4") land that a separate solid bronze spigot attaches to with a longer (and no longer) 'hidden' bolt. These pumps...

I bought a 1930 Standard Roadster about a year ago. It came with only one ignition key that was already cracked. Worried that it would break off inside the switch, I started looking for a replacement while I was replacing all the old wiring, rebuilding the distributor, etc. Somewhat new to the...

I'm in the midst of separating my old steel brake drums from the wheel hubs in preparation for switching to new cast iron drums. Does anyone know of a shop in Quebec (near Montreal, preferably) that has the tooling and expertise necessary to swage the new drums in place and machine them square...
