Hi all,

Like I said before i opended my 45 hours berg 650 2004,The only mods were a slightly cleaned up cilinderhead with in it special exh valves 31,5 from Lineaw and special X2 cam.

I had a view arguments with Dale regarding the air-fuel set up,From my point of view dale suggested me I ran too rich ,so I leaned it,and dyno-ed on performance and not on air-fuel,and I must say The piston Looks great,also the Valves.
So I have full confidence in the stuff from el sobranto.

After this I go for the special JBS racing kit,I know that the manufacturer is working hard with some people on board to deliver also a bullet proof product.

My husa 45 Hours was in perfect condition,the only thing that has some stress is the 3 and 4 th gear connection.
Piston perfect,valves perfect,cam perfect.according to ns man piston-liner perfect.
Only question axial clearance of the rod 0,43mm ,anybody any comment on this?????

thanks all so far to answer a lot of questions during 2005.

Greetings MADERO
 
Page D7 and D8 of the 04 Repair Manual discusses the connecting rod/bearing big end radial and axial clearance and the outer dimension of the crankshaft web against which the inner ring of the crank roller bearings are pressed. D8 shows how to measure the assembled axial clearance of the crankshaft and balance the axial clearance to the specified value.

I will post these pages if you do not have the manual, let me know!

Regards,

Joe
 
Hello Madero,

Here are pages D7 & D8.

This comment is from D7, which sets the connecting rod /bearing axial clearance and also establishes the sets the axial dimension of the crankshaft for mounting the crankshaft main bearing inner races.


Check the radial clearance and axial clearance at the
conrod bearing.
Radial clearance: max. 0.05 mm
Axial clearance: max. 1.00 mm
OUTER DIMENSION OF THE CRANKSHAFT
WEB
– Measure the outer dimension of the crankshaft web
using a sliding gauge as shown.
Outer dimension of crankshaft web = 60 mm ± 0.05 mm

For 650, starting with 2005 model = 61.2mm +0.05mm according to the 2005 manual.

This comment is from D8, which is the final measurement of axial clearance of the crankshaft in the cases.



BALANCING THE AXIAL CLEARANCE OF
THE CRANKSHAFT
– Place the crankshaft in the left housing half and mount
the right housing half.
– Mount the housing bolts around the crankcase and
tighten.
– Mount the dial gauge support on the engine case and
measure the axial clearance of the crankshaft.
Axial clearance 450: 0,15 - 0,25 mm
Axial clearance 501,550: 0,45 - 0,55 mm
Axial clearance 650: 0,55 - 0,65 mm
– Correct the axial clearance if the measured value does
not correspond to the setpoint value.
– To correct, remove the crankshaft and the inner ring of
the crankshaft bearing (7) and pull off of the crankshaft
with the special tool 584.29.037.037 on the ignition
side. Add or remove compensating disks and remount
the inner ring (see above).
NOTE: Add compensating disks if the axial
clearance is too large. Remove compensating
disks if the axial clearance is too small. Only
add compensating disks on the ignition side.


Does this answer your question?

Joe
