Time for the once yearly update!
My brother (PO of my truck) had been staying with me for several weeks a while back and he kept after me to get started back on !Oy
We managed to find some time one rainy Saturday and decided to start !Oy up and see where the oil leak in the front was actually coming from. I thought it was the timing cover seal as when I powder coated it, solder ran out of the area where the seal holder was.
It only took a couple of minutes to hook up the battery and pour some gas into the tiller tank I have rigged up and plug up the starting harness I made a while back. He started after about 10 seconds of cranking to get fuel from the tank to the carb!
We let him run for a few minutes while we did other things, then came back to see where the oil was leaking. I crawled under the truck with a flashlight and told him to rev the engine to about 2K RPM and hold it there while I watched for oil drips. When he did we both heard a strange sound coming from the mini-truck power steering pump but ignored it as it was cold.
I was so convinced that the leak was from the seal holder that I had purchased a used cover to replace it with! Imagine my surprise when the leak turned out to be from the bottom of the cover due to me over tightening the bolts and splitting the gasket!
We turned the truck off and I started working on cleaning up the cover I had bought. Since I had it, and I was sure it would leak from the seal holder eventually, I decided to go ahead and install it with a new seal. Brother was looking at the truck and asks, What's all this oil over on the drivers side? Huh?
Turns out the mini-truck pump had started leaking badly!
I can't win...
So... We decided to go ahead and strip the front of the engine in preparation for the timing cover replacement. Fast forward a few weeks...
I did some research on MUD and discovered that the mini-truck pump is known to be a leaker and rebuilds on it are hit or miss. I decided to do what I should have done in the first place: Go Saginaw.
I contacted Orange45 and he shipped me a pump bracket, a beautiful billet aluminum pulley, and a high pressure pump hose with the proper adapters for the box and pump. I went to Auto Zone and purchased a Duralast #6000 Saginaw pump and a cap for it. Pump was $66.72 with core charge, cap was $4.00. Cap Part # is 82581 and I found it in that HELP! section of Auto Zone. Be aware that all the tapped holes in the #6000 pump are 3/8-16 thread
You will also need the following:
2 2" long 3/8-16 studs (or just cut some 3/8-16 all thread down to size)
2 3/8-16 nuts
10 3/8 washers to use as spacers or
2 spacers made from whatever you have, or you can use washers. I had some brass caps the right size and made mine from that.
1 nut to fit the pump shaft to hold the pulley on. The pump does not come with this nut. It DOES come with the Woodruff key for the pump shaft. Auto Zone did not have the nut.
It wasn't until I had the old mini-truck pump off, and the new Sag pump bracket installed, that I realized the bracket was NOT going to allow my stock air cleaner to fit! Jim C stop laughing! No, I did not research this bracket before purchase...
So back to MUD for more research and I found on Apeterson's thread that I could weld an "extension" on to my OEM air cleaner mounting bracket and keep my cool old air cleaner. For those wanting to keep their air cleaner and do not want to weld you have two choices: Mark's Offroad has a bracket that mounts the pump lower and allows you to keep your air cleaner where it is, OR keep reading to see what I ended up actually doing. You can see the problem in this pic. The new pump bracket is installed which will put the pump right where the air cleaner sits.
The instructions that came with the pump warn that you MUST put bolts or studs with thread sealant in the two threaded holes on the BACK of the pump or it will leak. One of these holes we will use for the bottom mount, so I just put another piece of the 3/8-16 all thread in the top hole with teflon tape on it.
I mounted the pump to the bracket then started trying to figure out how in the hell folks were using a water pump bolt to secure the adjusting bracket for the pump. Nothing I tried worked. So.... I found an alternative way to do it.
I used the front shock strut bolt. You can see one of the brass spacers I made on the front of the pump. This setup allows a LOT of adjustment room so belt sizing will not be a chore.
Next was figuring out the bracket I needed to weld onto the OEM air cleaner. I cut a piece of 10ga sheet metal down to 4" x 6" to use as a rough template. I removed the OEM bracket from the head bolts and held it in position away from the pump while I eyeballed what I needed to do.
Plus with thin 16ga I'm afraid it would warp even if I alternate sides. Thoughts?
