C Series Engine Mount Plate

[C.M.C-175 0]

Are all C-Series engine mount plates the same except for the location of the bolt holes for the actual engine to mount on? I am repowering a C-175 with a Briggs and I will probably have to drill new holes to mount the Briggs engine to the plate, but was wondering if everything else is the same as far as the plate to frame mounting etc.?

I beleive all the mounts should be the same,Rick

The Onan and Kohler plates are the same height, The ones for Briggs and tecumseh are riser ones that lift the engine about an inch.

When we put the twin briggs on the C165 we just bought a plate from our local dealer. Just looked up one for a C161 with a briggs

Might also might depend if your using an L head or a V twin ? Ours has a L

Hey Thanks! I just looked up the engine cradle for a C-161 with a Briggs engine on Toro's parts website and apparently that part #106506 engine cradle is not available through the dealer anymore. I'll bet that is going to be a bear o find one of those used.

My mistake

Look up A1-16B801 a GT 1600 Workhorse with a twin briggs. Thats the plate we used. If it's not avaliable it will give you a idea of the shape. I'm not sure what Gator used when he put the V twin in his 520. Maybe he'll jump in

Just looked up the engine cradles for the Workhorse. Those engine cradles are still available, but it lists two different model numbers. The one is part # 110065 - Base Engine *R & the other is part # 109534 Base Engine. I am assuming that the Base Engine # is for the single cylinder Kohler and the Base Engine *R is for the Briggs twin. Would that be correct? There is quite a price difference between the two, I wonder what the difference is, unless its the height difference between the Kohler and the Briggs. :notworthy:

I used a 1982 GT-1142 engine riser/adapter plate under my Vanguard twin on the C-85 "experiment".

Sacrificing the rubber-mounted engine is no big deal - especially since the V twin is quite smooth compared to an opposed twin.

Craig - track Kelly down and see if he still has the mounting plate from the GT-1800/1848 he recently parted out.

Looking at the photo of the GT-1142 engine riser/adapter plate above,

it appears that the actual height of the engine mounting surface above the

frame is no different than it is with the vibration-isolating base plates found

in my C-111 and C-81 units. The GT-1142 unit appears to be rigid and does

not isolate engine vibration. Maybe with greater power, restricting engine

movement may be important.

They are the same. I went from a briggs to a kol on a c111. The mount is the same.
