Where is the oil filler ?
 
Hi, new here and new to inboard motors. Just bought a Alberg 30 1975 with an A4. This should be a late model, as per the year. But I cannot find the filler cap for oil that I see on every pictures of this motor. Serial # 193001, model 5101.
Thank you

I doubt it but may be you have an early model - is the fly wheel cover cast or sheet metal. If it is an early model the oil goes into a small 'flip cover" just to the rear and left of the distributor [use a small funnel]. Dipstick "cap" is to the right in a little well.

I just checked my 1991 Universal A4 parts list manual and the last page states "serial number 175503 [and higher] - "First engine with new style block- Front oil fill" Sounds like it should be where it is suppose to be?

opampca,
The oil fill will be above the flywheel. It is a 3" round plug with just some spring clips holding it in. I stole this pic from Moyer's home page.

Welcome to the forum. Have you found the dipstick on the aft stbd side??

The flywheel cover is sheet metal, and the thermostat is the late model... It is far from me (8 hours drive) I have a picture, trying to post again. Could be a mixed motor ?

Definately looks like a 'mixed' motor - where is the S/N stamped? Photo? Looks like mostly late model stuff, but the oil fill should be 'right there'.
BTW, you'll want to get rid of that 'trailer' plug in your harness - that's just asking for trouble.

This seems to be a weird motor...

I intend to redo the entire wiring of the boat. Also change the ignition to Indigo electronic ignition... will be very busy next spring, new boat !!! Working also on a "Openplotter" navigation system with OpenCPN. http://www.sailoog.com/openplotter

Did somebody make 3rd party blocks with a different oil port?

It is my understanding that early models did not have an oil fill at the flywheel end of the engine. The oil fill was at the transmission cover.

Sam 10-20-2018 11:16 PM

Ok - this looks like early model block with late model head and exhaust manifold. I have an early model A4 and the oil fill [not a round spring loaded cap] is a rectangular hinged flip cap port side of trans aft of distributor. Like I said before, dip stick round cap is hidden to the right of it.

Al Schober 10-21-2018 07:43 AM

The serial number you're giving is from the engine that donated the flywheel cover. You need to find the serial number on the block. Look on the side behind the manifold, just aft of the flywheel housing.

Another possibility: if the original engine was replaced with one originally intended for a V-drive, the oil fill might be on the other side of the head, with a pipe fill with a cap sticking out of the transmission access plate, pretty much on the boat/engine centerline. It'll be obvious once you see it...it just won't be easy to see until you worm your way over the spark plugs.

(In other words it might not be a Frankenstein motor.)

This alternative layout is very convenient for V-drive engines, which are mounted with the flywheel aft instead of forward.

I am not sure of all the A4 variants over time but I have a "virgin" 1966 early model [I think they ended in 1969] in my Morgan 34 and I help a few friends with their 70's late models. The moyer engine pictured in sastanley's 10/18 post is late model [t-stat on head, by pass, front oil fill etc] but it looks like it has the cast flywheel cover from early models?? I guess their is more mixing over time then I ever thought. Hopefully after all of this you found the oil fill.

If you do have a early block this, http://www.moyermarineforum.com/foru...ead.php?t=4010 may help.

Thanks everyone...

Very interesting... I will have more details in the spring when I will pick up the boat !!

I will check, but this type of cover is from late model ?

opampca 11-24-2018 01:16 PM

Finally I found the trick...
The block was changed 10 years ago with an early model...

Anything I should look after in this mod ?

Thank you
