John Deere 14SB with an FJ180V-CS11-R engine

12 years ago

I just installed an FJ180V-CS11-R on a 14SB frame, which I believe to be the same frame as the early JX75. (The original engine on the 14SB was an FC150V-FS00.) The new new engine fit with out any modifications, and the blade guide, pulley and BBC fit perfectly. The only thing I had to do was tap the mounting holes and shorten one mounting bolt to 1-inch. However, the throttle control works backwards, in that the choke is at the off-setting (throttle back) and off is at the choke-setting (throttle forward). If anyone has the trick to reverse this let me know. I don't see any differences in the parts diagrams when I compare the throttle controls for the 14SB and the JX75, and the governor on the engine I have is the same as the one on the later model JX75 with the FJ180V, so this has me stumped.

If you are unable to mount the cable differently at the engine, simply buy a throttle control that has a reversible throw.

Shredmore,
Need help!
1.After FJ180V installed, do you feel 14SB's mulching is better?
2.Which hole need a tap? if stand holding control?

Thanks.

Mower99,

Sorry for my lack of response - my junk mail must have intercepted all responses to this thread. Anyway, all four of the engine mounting holes on the motor needed to be tapped. Also, the mowers seems to have a bit more power in that it does not bog down as much, but it does not appear to be a substantial increase. I only installed the new motor since the cost to repair the old motor was as much as a new mower.

Regarding the backwards throttle, I was able to remount the cable onto a part I created from a piece of 1/16 inch thick shelf bracket metal and mounted on the governor. If anyone is interested I'll post some pictures and a template.

I was going to say you needed to put a bell crank in the line to reverse the direction of the cable.
