Electric fan for B7100HST

[ttfo]

Have anyone installed an electric fan replacing the factory fan to help cool the engine?

Look real closely and determine where one will fit! The belt on the fan hub powers the dynamo, so you'd have to figure that out also. Keep the screen clean and the radiator fins clean and the engine will run cool.

Because the B7100 only has a low output dynamo.
A good fan will wipe out the battery in nothing flat.

If it's overheating with the mechanical fan you have an issue.

This reminds me of a problem I had with a JD 4329 engine I own. A couple years ago it would overheat intermittently at first, but then regularly.
Cleaned the radiator, changed the thermostat, …didn’t fix the problem…..so pulled the thermostat completely….then noticed that when…looking into the radiator-cap-filler-neck…. No water movement was occurring.

Removed the water-pump…and found the impellor was not turning with the shaft…. so the water-pump-pulley being turned by the V-belt performed no actual water-pumping-work.

Replaced the water pump. Problem solved.

Just thought I’d mention an unusual type of failure for folks to add to their repertoire.

B7100's have no thermostat and no water pump.

Yep…my JD 4239 had reverted to a “thermo-siphon” ….(and also failed to properly cool.)
