16hp briggs and stratton knocking

Recommended Posts

Hi all, Nearly seized my engine today. Got it freed with some penetrating oil and a breaker on the flywheel. Lubed and worked it for awhile then tried starting. Started right up, lots of smoke, idle, idle, then loud knock, loud knock. Shut it off and I am suspecting I've turned a bearing. Any suggestions/ideas? Is it feasible to rebuild the lower end of this engine? Does anyone have a replacement they would be interested in selling? It is a 402707 B&S, I/C Vertical Shaft in a 1984 Deutz-Allis 616. Thanks for the help. Paul

Paul, I don't the engine you have but I'd sure try a new rod and bearing before I'd look for another. little light emeraly cloth job on the crank and it may run a long time. I've done that a lot on 8 hp briggs I ran on generator before I had filp the switch electric, bout 12 years worth, i'd get another year or 2 outta one. MPH

Paul, Apparently those motors are not that tough to rebuild, although more expensive when doing cylinders, valves, etc since it is a twin. I took one out of my Deutz-Allis 616 last year and still intend on rebuilding it. In the meantime, I have put in a 15.5 hp B&S I/C single cylinder I picked up new for $150.00. Installs very easily (new holes are already in the frame), and tractor runs nicely with it. You can find often find the single cylinder verticals relatively cheap new, so they are a viable option if you are not interested in rebuilding the tractor to original specs. Pat

Check Ebay !!! I got a brand new 20HP Vertical Twin II with oil pump and filter for $405 model 460777. These engines come up often, but be shure the seller does a good job packing it up. UPS bashed the heck out of mine and would not pay due to improper packaging. I got the seller to refund $200 to cover the busted parts. Be shure to check the model and type numbers, as there are at least 4 types of alternators on these motors.

The prob I've seen with these engs is that the top crank main bearing[really only a bushing] siezes up because it's the farthest away from the oil,or lack of oil!I agree, you can probably give it some extra life by putting in new rods/rings, and sanding the crank.Also check that top bush,A shortblock is the best way to go as then you get a new eng,internally anyway..
