cool hot intek: Installation tip V cooler & fan mounts

Cooler, There is flexibility in this so these figures are ref. MTL 5/8" wide x 1/8" Top strap drilled for mounting 3- 1/8" ctr-ctr. biscuit mount inboard on cooler flange, other end to inner side of tractor panel, and bolted tight. Bottom strap 4-1/2" long, angled down outside about 30 deg, from cooler flange bolted tight. Biscuit mount outside the side tractor panel. Holes 3 " ctr-ctr.

Fan, Very light sheet metal (16 GA , .062") Cut out to pick up 3 fan bolts and extend to back side tractor panel. On panel 2 ea 1.0" standoffs (tube or pipe) on outside of panel to set fan outsie cooler.Rough dims of mount 7" x 6". All rigid mounted.

A note on the cooler. With the biscuit mounts on the driver side and the two oil hoses on the front side of the cooler flanges you can move the cooler and feel the float of rubber. No vibe problems .

Stay tuned , say yea motoman, rave on. Motoman

cooling hot intek: installation tip VI oil pressure sender and gauge mounting

Are you saying " will the energizer bunny just stop?" Yes , after photos and this last tip. Do not use a mechanical oil pressure gauge. I had one and several new nylon tube/ compression nut spares which I went thru with bad results. Using the original (normally plugged ) port on front of stock oil filter protrusion I could not keep the connection tight and created some real messes in my driveway. Spring for the electric with its bulky, leak free sender-no more problems. The electric sender is big ( 2" can OD x 3-1/4" long) so it must mount driver side in the machined port I have mentioned and "shown" with arrow above. Look for it in the long promised photos (to come).

The dash gauges must be secured well due to bucking bronco ride.Use small nyloc nuts ( 8-32 or 10-32 or metric?) if you can find them. I just doubled lup and created jam nuts (two nuts each screw thread torque 'em lightly together0. PS I did not mention before hot/hottest oil pressure 35-40 PSI.

Pictures. The dash has a rubber sheet to help shock mount gauges.

Excellent thread. I was surprised to read that Kohler states anything under 300*F for the operating oil temp is acceptable-seems awful high to me but they do make engines.

i think you may have a serious case of tinkeritis :biggrin:............:thumbsup:

It would seem to me that you could improve airflow through the cooler by mounting it over the engine shroud intake.

I do like the use of the remote filter kit in this application to utilize more economical auto filters. I may even consider a dual filter setup.

Chev, The JCW oil adaptor order page asked " what car" so I chose Altima because of its popularity. If the part (s) are still available you may be able to choose other makes. By the way for those who think my fittings are ugly-they are. At that time I was punishing the tractor for the problems. There are brass, AN etc alternatives for "show." The oil adaptor is bottom- of -the -line and crude, but usable.Motoman

Chev, Sorry , did not respond to the airflow /cooler subject. Will take it under advisement, but I am afraid to mess with the air cooling fan. The extra load of draw- through might cause problem. Motoman

Now that you've gone through the effort to put a cooler on your machine, try an experiment for us, if you would;

1. Give us how hot your conventional oil was getting before the cooler mod.
2. Give us hot hot your oil is getting after the cooler mod.
3. Switch over to any of the premium synthetic oils that have been proffered here (Amsoil ASE, Shell Rotella T-6, etc.,) and tell us at what temperature your oil now runs at. I'll take a stab at between 20 and 30*F cooler for the synthetic.:smile:

When you posted how hot your oil was with the cooler on I thought you must have put on a really small cooler because it was not cooling like it should.

After seeing the photos I see you have a large cooler but it can't work properly the way you have it installed because you are just recirculating super heated air.

After the fan blows through the oil cooler it just loops around and goes through again.
If you cut a large opening in the hood install a grill like they have at Lowe's and build a fan shroud so it must pull outside air then you will be blowing cool outside air through the cooler instead of recirculating the hot air under the hood.

Also the hot air coming out of the oil cooler is going into the cooling intake for the engine and making it run hotter.
My 180 JD has a divider under the hood and it pulls fresh air instead of hot air from under the hood you could do something similar.

You could pull air in from the top of the hood for the intake for the engine.

If I put a oil cooler on my Z Trak i won't have these problem the engine is out in the open lots of fresh cool air.

I guess you could remove the hood on your tractor it would work much better with the hood removed.
