HELP setting final rolling torque

[ry57pont]

i just finished replacing all the seals on the propeller shaft on my 03 vp dps-m 1.95. on page 212 of the workshop manual it states to adjust the spanner tool to achieve a rolling torque of 18-26in lb with the spline socket on the driveshaft. i have the retaining ring very tight with the spanner tool and could only get a rolling torque of 13-14 in.lb i am afraid to put any more pressure on the spanner tool to get it any tighter. is 13-14ok? Thanks - Ryan

after posting i went back to it again, the retaining ring is fully seated. (threads bottomed). and the initial breakaway force is 17in.lb. once rolling 13 in.lbs. the only thing i have done is removed the propeller shaft housing and replace the shaft seals. actually the shaft seems to spin about the same as before (by feel) i would think that 26 in lbs would be way to much force.- any ideas?

Re: HELP setting final rolling torque

check your specs,usually the spec for rolling torque is 8-10inlbs lower for used bearings over new bearings.
its also why I try to remember to check rolling torque before teardown
out of memory I cant say if its set up like the sx lower or if its a tighten to spec set up.
will be after thanksgiving before I go back to the shop.
I hope.

The intermediate bearing between the 2 gears is what you should be tightening against. If you didn't remove any bearings then the shims shouldn't have been the problem. After you installed the bearing carrier into the drive, did you install the retainer between the carrier and the retaining ring?

If you did install the retainer, back off the retaining ring about 1/2 turn and see what the rolling torque is.

Re: HELP setting final rolling torque

the only bearings that came out were the ones pressed on the outer propshaft, and i left them on the shafts during dissasembly. the retainer is in, i remeber this because of the hard time i had installing the o- ring before i installed it.

if i back the retainer off 1/2 turn the rolling torque looses about 2 in.lbs (11-12in.lb).

this drive only had 100hrs on it, does that take into account for the low rolling resistance?

yes i should have checked rolling before teardown, but because the manual had a set spec for this i thought it was not a problem.


Happy Thanksgiving!
