Wiper vacuum

Carleschultz · Post by **Carleschultz** » Sun Dec 30, 2012 10:36 am

The entire vacuum is not connected(missing) to the windshield wipers on my M38 and I can not find a scematic to put this part back together. Does anyone know where to find a simple view and a listing of the correct parts to make it all come together? any help would be appreciated.

Wes would you have that info for a M38A1 ?

The underhood plumbing is the same as the M38. The windsheld of course mounts the wiper at the top, side vertical plumbing runs are longer and the M38A1 uses the stamped type on/off valve.

The plumbing from the wiper motors to the air cleaner are very much the same for the Jun thru Aug/Sep 52 M38A1 but then the underwater vent system was dropped at SN23359.

"K" is the suck hose for the wipers and that small empty hole between the top passenger side of the air cleaner and the battery cable clamp would have been the vent system line if it was ever installed.

There is a very good illustration of the wiper interior plumbing in TM 9-8012 page 317.

The wiper system parts are in the ORD 9 SNL G-758 pages 368 thru 372 and are very well described.

Thanks Wes! This is exactly what I need to put my wipers back in service. And I see that my fuel pump top is off by one bolt hole too compared to the one in the picture?
