John Deere R cold start issue

Le9102011 · Feb 13, 2020

Hello all I went out to the shed today to fire up all the tractors to get any water/condensation out of the oil and drive em around in this Wisconsin winter. All of the gassers fired right up with the exception of the hand start A thick oil makes it hard starting. Got to the R pony motor fired right up and went to start the big motor had the compression relief open for a few mins and it was awful slow to spin up to starting RPMs and as soon as I let go of the compression relief lever the starting engine lugged down till it almost died then it broke free and reved up while the lever was engaged and the big motor wasn?t turning. I have never been into this tractor yet and wondering if there is a clutch inside of the starting motor that is worn and needs to be replaced or if it?s just tooooo cold for to get this old girl started. It was 9 degrees F when I tried it. Any ideas or pointers would be helpful thanks.

I believe that I would wait until warmer weather to exercise my tractors. If you do have moisture in your oil, you could snap off an oil pump drive coupler and cause yourself a lot of work, just for a bunch of nonsense.

No use to start won't get warmed up anyway, wait till spring and loosen oil drain plug to check for water.

Well I would have to agree with both of you I used my G and a box scraper with ripper shanks to move the snow out of my drive way and break up all the ice and get some gravel to the surface and it didn?t even get to operating temperature. I?m just more concerned with the starter engagement if it is fact of need of adjustment to get it tightened up or replaced.

there are actually 2 clutches a regular disk clutch that can be tightened and is engaged when you pull second lever back .One lever is decompression lever one engages pinion and engages clutch.
The second is over running clutch. If or when big engine fires it won't over rev pony . It does not fail very often but had to replace recently on 820

I never stat anything if i am not going to use it, even in summer time.

When you burn hydrocarbons one of the byproducts is water. My practice has never failed me.

There is an original JD "R" service ,manual on e-bay..

John Deere Model R Diesel Tractors Technical Service Manual - SM(2-2-51)

I purchased the same JD Original SERVICE MANUAL..........
To own a Tractor without a service manual..........

My biggest pointer is do not start them in winter if not needed.

You really need to run them several hours at operating temperature to remove any amount of water.
