Fixing the 1998 HMMWV

[mrandig]

Going through my parts tonight, I came across something I seem to be missing.

I don't think this is something that got dropped during disassembly; I don't think I ever had this installed.

Can someone tell me anything about this (#8 in diagram)?


The TM -24P (Figure 33) lists this item as "washer, shouldered", but I've also seen them listed online as an "alignment washer". It's not shown in the -20, only the -24P.


Thanks in advance. If I need to buy it, then obviously I need to get one before I start putting things back together.

The only problem with a $1.25 part order is the $18.00 to get it mailed out.

I don't know about TN, but here in TX finding random hardware like this is becoming more hopeless by the day. The mom and pops have all closed, ACE must be going bankrupt as it never restocks any more, and HD, well HD never fails to disappoint.

My chances of finding this, in the correct size and dimensions, is very low. Unless I'm looking for something very, very common, I could spend hours looking for this, beyond any time already spent.

Easier to just order online, add a couple extras to justify the shipping, and work on other tasks until it arrives.

Power steering cooler, hydro-booster, and fan clutch hydraulic lines

Since I've got some room to work now, I'm going to replace the power steering cooler, hydro-booster, and fan clutch hydraulic lines. Once this is done, we'll replace and connect the hydro-boost unit, then replace any remaining hoses connecting to the power steering pump, since we still need to replace that unit also.

First, we'll replace the hoses at the steering box. The blue hose goes up to the hydro-boost, the plain rubber hose routes forward to the steering cooler.


Hoses running along the frame to the cooling stack.


I've got a whole box of 3/8" transmission oil cooler hose; for this exercise, 25' should be plenty.


At the Cadillac valve, the left hose routes forward to the steering cooler, the center hose goes to the fan clutch, and the right hose will go to the hydro-boost, which we'll get installed here in a few.


The two thick hoses go to the oil cooler. We'll also replace these hoses while we're down here.


The fan clutch hose that's installed here matches TM-20 but not TM -24P. Per the later, this should be a different hose and have a tee with a bleeder and cap at the Cadillac valve, but that's not the case.

Since it all works as is, I'm not going to over-think differences between the two TM's. I just made that mistake in my last post. I'm just going to replace the hose and move on.


It's hard to see here with so much clutter, but progress is being made. We'll put in the hydro-boost next.
