Hello everyone . First post.
looking for advice . I'm working on an Oliver 1850. First issue is the engine, a Waukesha straight 6 gas engine. Doesn't have the power it did years ago . I did a compression test. I have 180psi on 4 cylinders and160psl on 2 other. Is this considered acceptable ?
 
Hi would say that should be good enough I would advance the timing and see what happens A late timed engine lacks power
 
It strikes me that would be an awful lot of compression for a gas 1850 or gas anything for that matter. I'd try higher octane fuel if
your gauge is accurate. gm
 
Start the engine and get it up to working temp. Shut off and let sit overnight. Next morning start and immediately shut off. Remove the plugs and look for water droplets on electrodes. The book sez that there should be no more than a 10 percent difference in compression between cylinders.
 
What type of gas are you running, Good
clean fresh non-ethenol? Is there rust in
the tank? Have you done a tune up and
checked the timing, clean the carb and
check the float? I woukd also check and
adjust the valves. Start with the basics.
 
Hopefully this reaches everyone as I hoped. Those are all Good suggestions. I will try them all. I live on a farm in southeast
Pennsylvania and grew up driving this tractor. It's been maintained over the years. Now it's showing it's age.

This is a 4 wheel drive Oliver 1850. I'm trying to look at all issues I have. All your advice for the engine is Good. I will try
them all.

the next issue I have is gear oil is seeping out of the transmission into the 4wheel drive unit. I'm going to pull the engine
today. Then the hydrostatic unit. Hopefully then I'll be staring at a 4 wheel drive unit.
 
Any advice on removing the PTO shaft? I watched the Oliver guy on YouTube and read the shop manual. I removed the snap ring.
Pulled out the stub. Removed the o ring. Spun the pto shaft with the main shaft back into the crankshaft. Used and impact gun
while pulling on the shaft. I come to the same end as the guy in the video. only I don't have the transmission opened to look in
the top.
 
Thank you. Shaft is out. Tried everything. Finally resorted to the impact gun. It came right out. It was the last resort, because
it seemed the most violet .
by the end of the weekend, I hope too have the engine and hydrostatic unit out. Finlay getting to the four wheel drive unit.
Does anyone have any advice, stuff to watch out for?
Thanks in advance.
