CC no i did not check the timeing marks[But i will]😮 There is no dowel pin on it.The other problem was that when i put it togather i did not get the set of dogs lined up that go through to turn the pump and had to pull it out again[did learn from that one]😊 Thanks

The 5J parts book shows 2 dowel pins a little below half way down on each side of the transmission case face. part number is S-1177

also see a bushing on the clutch housing picture that seems to stick out enough that it might act as an alignment fixture. 2A3658 Not sure what that is.

CC i guess i did not fully understand your question.😕 There are two dowels on the bell houseing as you said about half way down both sides, I checked the timeing marks today and i must have had a angel on my shoulded when i put in the flywheel. It is right in time😎
Thanks

Hi catrat,
is the measurement you have posted at 0.050" the total indicator reading (twice the error) or the actual error,(half of the TIR) ie, the amount you need to move the components relative to each other to get 0.000" indicator movement ?

My D2 SRB gives flywheel runout specs at :- Outside dia. max. 0.006" (0.012" TIR), and Flywheel face max. 0.006" also. These are measured with the indicator mounted on the flywheel housing and the pointer on the flywheel faces and the crank rotated 1 turn and readings noted at their max. and min. dial readings.
This would indicate that your 0.050" is much to far out of spec. and is the most likely cause of your problem.
Also given is the max. runout for the flywheel housing at :- bore 0.010" (0.020" TIR) and face 0.010" also, these are measured with the indicator on the flywheel and the pointer on the flywheel housing faces and the crank rotated.
Hope you can follow this description and that it helps.
Cheers,

EDB that is what it shows mounted on the houseing and touching the flywheel in one turn. I ain't no good at them small numbers it is 4 to 5 thousands in one turn. goes up to 4-5 and back to 0 going around.That is what my machinest neighbor tells me. He says that is not very much. My spelling ain't much better.
Thanks

Hi catrat,
the readings you have posted last are within spec. and will be good to run.
You are lucky to have a machinist neighbour to look over your readings, as he says it is "very little" Actual correction to get a zero reading in your case is 0.002"-0.0025" this is way under the 0.006" of the spec. dimension.
Those pesky dial indicators can be confusing to read down in the bowels of a flywheel hsg. especially when trying to read them with a mirror and upside down.
Good luck with the rebuild.
Cheers,
