Hi,
Similar question to the original one in this thread and am interested in adjusting the drive clutch of a D4D.
I'm unable to locate and view the instructions below.
Dad is using two mighty D4Ds. The newer one we have a parts book/service manual on order but it hasn't arrived yet and we are in reasonable urgent need of some help.
Thanks
Jed
Hi Team,
hope this helps.
As you have not given a Serial Number I guess the procedures for both dry and wet M/C are needed, just in case, as they are different.
For the Dry M/clutch, the method I have given is for an earlier machine with two housing openings--yours should have one big cover on top to access the adjustment by but otherwise is much the same setup.
If you have a wet/oil M/clutch do not over tighten the lock plate nuts as the studs are soft and will strip easily--sort of rough fix for this is to run a 5?16" UNF die nut down the stripped 3/8" stud to save pulling the clutch out to replace the filed stud.
If when you loosen the lock plate nuts and the plates do not release you just need to give the end of the stud a light tap with a hammer and punch.
Serial Number helps us give you the correct data. Cat only deal in S/No's as they continually updated machines with improved Parts etc. as the need arouse, and the updated Part Numbers are effective from this point as dictated by Serial Number.
It is likely yours has an Australian Serial No which I can convert to USA Equivalent S/No's if needed. USA S/No books are easier to get as Cat Of Australia only printed enough books here for the machines built plus a few spares back in the day.
Hope this helps.
Cheers,
