Greetings,
Mr. mp. Could it be that the bolt is reverse thread?

(Excuse the drift but)George, is that just academic interest or is there a Malagari engine issue. Hope not. Fortunately IGs have good access, 2 removable floor sections plus the ER hatch.

Well I went out and tried both ways and no luck. I don't think its reversed thread.

This is one part of the engine which does not seem to appear in my manual

As for this

After moving the engine to the aft deck I had the boat yard lift it and put it on a trailer. It took them 20 mins and doing it myself seemed like a hassle.

3/4" breaker bar, socket, and extension pipe should get it. I think it is std rotation threads.

Also a 2x4 between the block and crank. If whatever is locking up the crank would break loose you won't get hurt.

Bruce, perish the thought - just academic interest

Well here is the bolt. (I did not include pictures of the wound on my forehead and scraped shin from getting this thing off. I can't believe how much force it took).

Next I'll need a pulley puller I guess.

One interesting thing is as I attempted to remove the bolt, even with all that force the crankshaft did not appear to budge a bit. Something is really seized up.

Ok. Well here it is. It looks to me like I have problems with the journals and bearings on cylinders 3,4 and 5. I noticed when I opened the crankcase the piston counterweights on 3,4 and 5 were dry compared to 1,2 and 6.

Another interesting thing is when I loosened the bolts on 5 it really stunk up the entire garage . I don't know if it was a burnt oil smell or what but I thought I was back in the Ohio river valley under neath a steel mill smokestack.

Any thoughts on what I need to do next? Also it does not appear to me there are any liners in this engine but from what I can see so far the cylinders do not look bad. One has a slight scoring. I guess I'll need to check the block for cracks but there was nothing obvious to me.

Mind you, this is arm chair diagnosing, but the center journals starved of oil and most likely seized the motor. #5 is just gunked up with burnt oil and of no real significance.

I would guess that either the oil pump lost pressure or you somehow spun a crank bearing (doubtful) or the main oil gallery got plugged (also doubtful).

I would take the oil pump apart and see if it broke the gears or possible the drive to it broke.

Either way, it may be that the crankshaft is toast. You need to get a machine shop to determine if the journals can be turned down enough to reuse it. If so, easy. If not well You really need to consider your options. The crank wont be cheap,

Sorry to see that happen.

That engine Alfamike has for sale is looking shiny, and just might be spinning its crank in your direction.

Looks like #5 spun the rod bearing that seized the crankshaft.
Crankshaft grinding can be tricky. If you go that way you should consult with ADC to make sure oversized bearings are available.

Yep....the first thing to do is to take the crankshaft to a machine shop that can do a magnaflux or ultrasonic test for cracks. If is toast, that may sway the rebuild/replace decision. I got lucky a few years ago with my dozer engine that spun a bearing and crank failed testing. ....got a used crank out of a trackhoe engine for $300 (common engine), had it turned down a hair, oversize bearings, and was pushing down trees again in a couple weeks. I'm doubtful the FORD crank was as prolific as my JD, so a replacement crank may be made of gold..... Good luck!

The journals are 2 1/2 inches in diameter. I don't know what the minimum specifications are but it would seem there is enough material there to grind and still maintain enough strength. I guess that is a wild guess though. How does one find the minimum specification for these anyway?


I'll call AD on monday to check into these questions and to see if they will have undersized bearings.

I sure hope the crankshaft is not completely shot that would be a real bummer.

What about spray welding if we need to add material? Has anyone ever done that to a crank? I figure I'll have three journals to fix.

All of the other bearings appear perfect.

Another question - why is it that these two center crankpins/pin journals (?) do not have oil holes like all of the others?

The issue with grinding a journal is you need to make sure you don't break thru the heat treat zone. I will be deep enough in the center, but shallow on each end.
I have seen several Perkins crankshafts break after grinding with low hours because of the above.

I asked about a new crank when we had our FL SP135 rebuilt. $2,500.
