I decided to take the bull by the horn's and not wait for a reply to my post on electric fan install.

 I don't know about jinma 254 but there isn't a lot of room between the battery and the radiator. Hayden, the fan people noted that  the fan installation have  minimum of 2 inches between the fan intake and surrounding engine parts. I guess if you had a very small battery that might work. I have a cat battery, although is is long it is the same width of the original battery I couldn't find any way to install the hayden 3680 12 inch fan on the battery/filter mounting bracket.

Here is what i ended up doing:  1. Removed the battery and air filter to allow working room.

                                              2. Remove that worthless filter

                                              3. Remove the second brace down from the top

                                              4. Twist the next lower brace with the top of the brace now turned out

This now allows the fan to fit snugly up against the radiator. TIP “comb out the radiator fins if they need it”, mine did.  In checking measurements from the battery to the fan it was like zero clearance however, there is enough room to shift the battery forward. This created a whole new set of problems. 

                                                A. The battery forward hold down ties were now to short.

                                                B. The battery in being shifted forward no longer had the back of the brace to it from      

                                                    sliding around.

                                               C.  The original battery position is about 3/16 lower then the forward area.

                                               D. The bolts holding the cowling on pressed tightly against the battery when shifted

                                                   forward.

                                               E. Last but not least the positive cable was now to short.

 

                                          5. Made new forward hold downs. Couldn't find the right length  bought longer ones and cut                                               bent and drilled new cotter hole.

                                         6. Cut piece of galvanized metal to cover the original battery compartment to bring the whole                                              level. Drilled holes to allow water seepage. covered entire area old and new with rubber                                                  belting material.

                                         7.  Removed bolts holding cowling on at the from bottom and cut off the excess. Placed                                                        rubber across the whole length covering the remaining bolt exposure.

                                         8. Drilled holes in bottom of the new battery compartment and installed small all thread to a                                                 hold down that I built to match the forward horizontal hold down.

                                         9.  Installed new positive cable.

                                        10. Slide fan into place tipping it slightly, it slide right in. Mounted it with the thru radiator                                                     mounts provided. TIP make sure it is in the pusher position supposedly it comes from                                                    the factory that way, mine wasn't. Had to turn the blades around.

                                       11. Install the electrical as to your preference. 

I installed the 3654 controller very simple just follow instructions. Although it didn't require it I add a switch to the dash and 25 amp from my new fuse block (in recently installed a delco 10si 105 amp single wire and a new fuse panel to handle any new accessories. Duh!!  I forgot to take pictures I will take it apart later and try to get some pics  . 

the good news is it works great.. engine runs up to operating temp  around 170 and barely moves off the mark even brush hogging in the really hot weather we been having.. Hope it helps..
