Thanks again for your info. Interestingly enough Bobcat stopped making a gasket for between the carriers and the chaincase. They have gone to the liquid gasket now. So I will do as you suggested and just silicone it up. As for the chain connecting link the manual says #100 HS roller chain so I...

Yeah that has to be where the oil is coming from. It is definitely chaincase oil. So let me tell you my plan to replace the gasket between the carrier and chaincase and let me know if you think it will work. I am going to break the chains, I just ordered a good chain breaker tool, where can I...

I did fill it to the bottom of the threads on the plug in front, 10 gallons. I also should mention that the machine was not run at all in between the time we filled the chaincase and the time I noticed the leak, overnight. My first thought was the drain plug, but I RTV siliconed it when I put it...

I just finished all 4 axles with bearings, races, seals, even had to go with one new axle, sprocket, and hub assembly. I thought I was all done, and got everything covered up. I filled up the chaincase and the next morning I have a pool of oil on the floor. It is leaking all the way down the...

Sorry for the delayed response, I was away from a computer for longer than expected for the holidays. I will be honest I learned a lesson in doing my project. We started this as more of a trial and error repair, when we should have just done a complete motor overhaul from the beginning. Our...

Sorry for the lengthy delay, I did not expect to be away from a computer for a week through the holidays. I do have a service manual and a good many parts schematics sent to me from my bobcat dealer. There is a special tool to check the compression. It replaces the fuel injector to test. I...

I have an 873 with the same engine that I just rebuilt. Memoparts is a great place for parts for these engines. Get your model and motor number off the serial tag on the valve cover and give them a call. They have great prices. Go to memoparts.com to get their info. I feel like I am advertising...

Hey sorry for the delay in response. I am trying to locate my write up on it. I believe I left it on my work computer, so I will attempt to get that to you tomorrow.

Let me start by saying I feel your pain. I bought a 873 this summer that sounds like it was in about the same condition yours is, but probably and hopefully worse than what yours is. I will spare you the scare of what I have put in to mine and what all we have done, but when I bought it there...

So I did get the assemblies out. I felt inside the hole in the housing and did notice the grooves. I talked to loaderpartsource yesterday and he's never heard of the different sleeves that move the oring location. I talked to the dealer this morning, and he hasn't heard of that either. The...

I just got done completely rebuilding my 873 engine. The interval on the timing belt is listed at 3000 hours or every 5 years. But from what I have heard and read you are lucky if you make it that long on these engines. I have the write up on it. If you update your profile to list your email I...

I am actually trying to track down the reason my 873 is popping the dipstick and spraying oil on startup. I took the hose off the bottom of the PCV module with the ball in it, blew in the hose and heard bubbling from the check valve on top of the block. So that valve seemed good. Since I got...

Thanks for the information. So to make sure I understand correctly, if I feel 2 grooves inside the hole in the pump housing I need to get a new sleeve? And if there are more than 2 grooves this has been done before and I need a new pump? Does anybody know if loaderpartssource would have these parts?

I am really hoping you guys chime in with nothing but good news. Hey at least I put this in the right place this time!... So I got my 873 running. Now I am just chasing down leaks. I got one that is really concerning me. It is leaking up from the spools out of the hydrostatic pump where the hand...

Amen to that! I now probably have half of the schematics from their system for my machine as I have had to have my parts guy at the dealer email me the schematics so I could pick out the parts I am talking about. So the process right now is call the dealer, try and describe the part (major pain...
