New from the Baker Drivetrain Masterminds the Plus 1.5

Keep Late Model Touring H-Ds Cool and Alive

Baker Drivetrain masterminds are constantly looking for new products. Did you know Lisa Baker is a mental member of Mensa. She is a brilliant engineer, and Bert flunked out of the MMI sparkplug-changing class at the mechanics school, but he likes to think of himself as sorta cool.

Actually, he is also an engineer, but we can't seem to find out who is the mastermind and who cleans the shop after hours. I suggested a new product line to Bert this year in Sturgis. I can only find one complaint about Victory motorcycles, the clunking in the gear-driven primary drive. They need a belt drive solution. Bert was smiling and chatting with other magazine guys, then turned and glared in my direction, "I don't need more projects," he said. But I could tell the wheels were already turning.




Before I jump into the benefits of this new Baker product, I want to point something out. Bert and Lisa fell is love with motorcycles and they're devoted to the cause. The custom motorcycle market is dinky, and if they wanted to really make the big bucks, they would design toasters, but they're hooked on two-wheels, and I'm glad they are.




This unit was specifically designed for late model touring Harleys (2009 and later), and unlike oil coolers, the +1.5 pan reduces the engine oil temperature, by 16 degrees or more, whether the bike is moving down the road or stuck in traffic. It adds a quart and a half of lubricatin capacity to the long distance H-D models with dinky oil capacities, sometimes less than 3 quarts.

Not only will this add more miles to each oil change, but it also adds substantially to overall life of any engine, especially during a time of cost and quality withing twin cam engines. So this puppy could be a life saver.




The plus 1.5 is a two-piece 6061-T6 aluminum construction unit with metal core gasket. It features cooling fins on the bottom with a highlighted finish. The returning oil supply follows a series of co-planar baffle labyrinth channels. The hot return oil travels from front to rear on the top plane and back to the oil pickup, in the front, on the bottom plane for complete oil circulation.

It is also clearanced in the rear for crossover exhaust pipe compatibility. They designed in zero leak drain plugs for engine and transmission oil. According to the Baker team installation is easy and requires no modifications. Just remove axle from rear wheel and move the wheel rearward against the fender to remove stock pan and
install new one.

To realize maximum engine cooling benefit
Install the +1.5 pan and fill the oil sump to 5.5 quarts (+1.5 quarts) to realize the maximum reduction in oil temperature. Oil fill level on the dipstick will read the same as stock.
 

To realize maximum oil blow-by reduction
Oil blow-by on Screamin' Eagle 110 engines is a chronic issue for aggressive riders. It is caused by the larger displacement engine building up pressure in the cam chest and the oil sump. This forces oil up the push rod tubes, out the head breathers,
into the air cleaner and all over the right side of the bike.

Harley advise dealers to run the stock oil sump 1 quart low to increase the volume of air in the sump. This corrects the blow-by issue but makes the oil temperature skyrocket. By running the +1.5 pan at .5 quarts over stock (4.5 quarts) the blow-
by condition can be cured with a small improvement in oil temperature reduction.

DISSASSEMBLY:

1. For your safety, DISCONNECT BOTH
BATTERY TERMINALS (FAILURE TO DUE
SO COULD RESULT IN PERSONAL
INJURY).
2. Remove the oil and transmission drain plugs,
drain fluid and dispose of at your local
recycler. Remove the oil fill plug with dip stick.
3. Remove the saddle bags and place them out
of the way so that they don’t get damaged.
4. Remove the right side and left side exhaust
muffler. Remove the left side muffler at the
catalytic converter section; the crossover
pipe will stay attached to the left muffler,
figure 2.
5. Remove the exhaust hanger located rear of the oil pan.
6. Remove the rear brake caliper from the
bracket by removing the 2 fastener bolts and
sliding the caliper off of the brake disk and
hang the caliper off of the bottom saddlebag rail, so it's out of the way.
 

DO NOT JACK ON THE
CROSSMEMBER OF THE FRAME
AS THIS WILL BEND. THE JACK
SHOULD BE PLACED SO THAT IT CONTACTS BOTH FRAME RAILS.


7. Place a bike jack underneath the frame and raise the rear wheel, so it’s just barely off of the ground; enough to get the weight of the bike off of the rear axle. Remove the rear plastic belt guard. The front bolt of the guard will stay in the swing arm, this will aid in the pan installation by holding the belt out of the way.

8. Loosen the rear axle, slide tire forward then sl
remove the axle. Now slide the tire all the way
back, inside the rear fender. This will allow
you enough room to BAKER 1.5 oil pan.
9. With the bike still supported, take a few 2 x
4’s and block up under the motor area of the
frame so you can remove the jack (get it out
of the way) and the bike will stay supported
properly. Make sure that you block this up
under the motor so you have enough to
remove the front oil pan bolts.


10. Using the front belt guard bolt; loosen the bolt
up enough to stick the rear belt underneath it.
This bolt will hold the rear belt up and out of
the way, while you work on the oil pan.

11. Remove the 12 retaining bolts from the stock
oil pan and remove the pan out the left rear
side of the motorcycle, figure 6. Make sure
not to damage the transmission to pan gasket
surface area while removing the pan.

12. With the pan out of the way, use a clean lint
free cloth or shop rag and wipe the gasket
surface clean.

BAKER DRIVETRAIN SHIPS THE
1.5 ASSEMBLED. THE PAN MUST
BE DISSASSEMBLED FOR
INSTALLATION. MAKE SURE THAT
YOU DISSASSEMBLE THE PAN, USE
SHOP AIR AND BLOW OUT THE
INTERNAL AREA OF THE PAN TO GET
RID OF ANY DEBRIS THAT MIGHT BE
PRESENT FROM SHIPPING.


IF YOU ARE GOING TO RUN A TEMPERATURE
SENSOR WITH A SENDING UNIT, REMOVE THE 3/8” NPT PLUG FROM THE FRONT OF
THE BOTTOM OIL PAN AND INSTALL THE SENDING UNIT WITH PIPE THREAD SEALANT
AND SNUG INTO PLACE.




BAKER 1.5 INSTALLATION:

1. Make sure and wipe down the gasket surface
area of the transmission with some brake
cleaner using a lint free rag. Referring to the
exploded view (figure 1) get the top pan bolts
(9pcs of 1/4-20x.750” SHCS) ready by
applying Blue Loctite to the threads.

2. Install the top pan with top gasket through the
left rear side of the motorcycle, figure 7.
Install the 9 bolts; just start the bolts for now
making sure that the top gasket is
aligned properly. Use two of the 1/4-
20x2” SHCS bolts and just start by
hand to keep the gasket aligned. Snug the ¾” long bolts
then torque to 110-130 in-lbs following
the sequence in the Baker installation instructions.

3. Remove the two 2-inch long bolts used for
keeping the gasket aligned. Prepare
the remainder of the BAKER 1.5 bolts
by applying Blue Loctite to the
threads.




BE VERY CAREFUL WHILE INSTALLING THE BOTTOM PAN
WITH GASKET NOT TO DAMAGE THE GASKET DURING
INSTALLATION. MAKE SURE GASKET IS ALIGNED WITH DOWEL
S BEFORE PUSHING UP INTO POSITION.


4. Install the bottom pan with gasket.

5. After the bottom pan is in position and seated
with the gasket aligned install the bottom pan
bolts. Snug and torque to
110-130 in-lbs.

6. Following your Factory Service Manual re-
install your rear wheel with belt, belt guard,
exhaust hanger bracket, exhaust mufflers,
and rear brake caliper.

7. Fill transmission fluid per your Factory
Service Manual and fill the BAKER 1.5
with motor oil of your choice. We
recommend Spectro Synthetic V-Twin
20W50 motor oil and Spectro
Synthetic 75W140 transmission fluid.

8. When filling the motor oil, refer to the section on oil use; depending which way best suits
your needs. Test ride!

Follow your Factory Service Manual for
recommended oil change intervals.
