Ross master pump


<image src="http://forums.yesterdaystractors.com/photos/mvphoto9336.jpg"/>
I would like to know what the secret is to installing the pump driveshaft seals on a little Rosa master pump for my 1845 case. Had the pump rebuilt and now I got fuel in my engine oil. Seals were done by my buddy when he put it in but he complained about installing the seals. When I saw the fuel in the oil I ordered more seals and the tool. What is the deal with these seals ? Is it that big of a job ? Can?t even find a video of an install ? &#128545;. Any help would be appreciated my brothers &#128077;
 
Be careful nut to cut or tear them when installing on the shaft.

Then, lube 'em up with a little light grease and carefully install the shaft and seals into the IP, without cutting then, or rolling them over.
 
Even guys at our Deere dealership shops had a hard time with that job (some of the guys). Takes some finesse. Make sure there is no ridge in that bushing from wear. If that pump was repaired, that bushing should be brand new (it only cost $6).

Put some motor oil on the seals and on that bushing. Then slide the pump on with very little pressure when using that compressor. The key is that pump has to go on with almost no pressure from you. If you have to push it hard - you can assume you flipped over the one seal that is facing the pump.

We had guys in the shop that always got it right the first time, and others that could never get it right.

I'm sure its self explanatory but the seals go on the shaft, back to back..
& the trick, other than the compressor tool, is lots of lube..
Make sure to lube the tube also..
Use something "light".. like engine oil or vasoline.. I find grease is a lot heavier & doesn't wash out of the system.
Got any vegetable oil around??
Good luck.
 
Dude that?s awesome. This explains a lot. I helped get it off but was not there when he put it on. I can see how the install could go south in a hurry. Thanks &#9996;&#65039;
 
I wouldn't attempt to put a pump on an engine without the tools & I've got 30 years experience. LOL
I even use them when I have a pump on my work bench..
I OFFER the tools to most every customer I do work for.. some take it & others don't..
I started asking for a deposit now tho, refundable when the tools are returned.
"I WISH" I had all the shaft tools I've "loaned-out", back..
 
He has the only tool he really needs. I have also installed many without that compressor and did fine. Just takes some care and innovation.
 

There is another tool that is a tube with a tapered end..slides over the shaft to help slip the umbrella seals onto the shaft.
 
Yes, I have one and never use it. Never ruined an umbrella seal yet by simply installing by hand.

Lots of tools make jobs easier. That said, lots of things can be done without them.

Have not used the seal compressing tool for years, just lots of seal slickum and my fingers will get the seal started in the tube IF a fellow is careful..
 
I use a dull dental pick. Been doing this way for 30+ years. Sometimes I used a tooth pick or whatever I can make work. More you do the easier it gets. Trick is to wiggle the pump and NEVER Push, just let it glide in. Should slid forward easy, or you have a seal rolled over. Just a dab of grease, oil, or whatever you got on hand. Al
 

Last spring I got my pump rebuilt then just slapped it back in. I don't have any special tools. I don't think that I put anything special on them.
 
Me and buddy used the tool. It went slick and easy. The tool is peace of mind for sure. I would not recommend doin the job without it. For 20 bucks it was worth its weight in gold.
