No response in Wheel Loader Section

[rodbaron]

Hi. I'm new and posted in the Wheel Loader section what my topic is. I've had only one response from someone from Italy wanting to send me a service manual or something which I'm admittedly skeptical of. Can someone guide me on this forum so that I can receive a more thorough set of responses? I felt like I presented with enough info to bite on but maybe I'm missing something. Here's what I posted below minus the pictures I posted of my unit... a 1985 Clark 75B with Cummings 504.

Thanks in advance!

POSTED PREVIOUSLY:

Hello all! This is my very first post here. Last year I purchased a used loader to do some heavy work on our land. I've owned a few skid steers, farm tractors and we have a decent sized excavator. I wouldn't say I'm a pro by any means. Especially when it comes to knowledge of these machines. I'm a peripheral parts changer and a mediocre operator.

With that said...Wow! This machine is a screaming beast! It also needs my help after serving well over the last year.

Here's what I need to do to get it going again. Any help on locating parts and hacks to repair is greatly appreciated:

1) The left hydro ram that raises the bucket (or forks) leaks like crazy (2-5gal per day based on usage) and I need to find a seal kit for it.

2) Need ring seal around tire beads x 2. Ours are rusted and pitted and tires leak down quickly. We spend 45min airing up tires each use if a week between use.

3) Throttle pedal sticks like crazy. This has not ended well when moving in tight spaces. We've mowed down a few fences when someone new to the game has hopped in it. We don't tell them on purpose. Haha!

4) Where exactly are the stamped serial numbers on the front and rear of frame? This would save me alot of trouble. The badges on the side are almost completely worn.

On the engine info I can read it has a manufacture date of 10/84, V-504-C, engine number 20239471, So. No. D 7878, Engine Cert ID: C.I.D.504, Family: None, CPI: 5023

On the badge thats almost completely worn I can read 75B for sure. To the right of that all I can make out is 3D23...maybe a zero after that.

I can post pics of the badge if anyone wants to take a crack at it. I will also post pics of the loader as they are on my mobile and I am currently on a laptop.

Thanks in advance!

Sometimes it can take a little while to get a response because no one is real familiar with the machine you have. I think Minn Parr may have some parts and maybe manuals for Clark Michigan loaders.

A Clark 75B is old enough that many who were familiar with them are no longer around and those still around have forgotten alot of what they knew. I will respond on your other post so that we don't end up having 2 posts going.

Thanks. I appreciate your post and will look on my original thread under the wheel loader section. These are the largest machines I've ever worked with and on so I'm both amazed and intimidated but also excited. Lots of power!

Thanks. I did contact MinnPar before I wrote my first post on this forum so its been about a month now I'm guessing. Their site doesn't offer a phone number so I simply emailed an inquiry on their "contact" page. You just reminded me to send another one which i did just now so hopefully I'll get a response. Does anyone have a phone number or email for their parts department?

Does your loader have 25” rim tires? If so, I believe all you need is a new o ring. These are also available from anyplace that services or sell large equipment tires. The cylinder packing may end up being a bit more involved. While Minn Par may be able to get you a part number or even a kit, the price may be very prohibitive. I am a big fan of just pulling the cylinder apart and measuring individual seals, backers, o rings, wipers and wear sleeves. I usually purchase all of my seals from a place called Baum hydraulics. They have downloadable catalogs on their website that really help sizing things up. The staff is really helpful too if you run into trouble. As for the throttle linkage, I’m guessing a bit of lube and a bigger return spring will get you going in the right direction.

This is very helpful and simple info. Thanks much! I thought same to try first on throttle linkages and moving parts. We were working in a ton of dust so it hopefully just got dry and sticky/binding up. I checked out Baum...lots there! My tire guy is mobile and says he only does tires. I get that. I'll hunt down a large equipment tire dealer in my region and see if I can turn up anything and will measure the rim and look at tire size again then circle back. 25" sounds about right. Thanks again!

Since multiple threads on the same question can cause confusion, let's close this one and keep all the replies in the original, which has gotten some replies as well:

I'll also *copy* several of the replies above into that thread, meaning they'll still be visible here, but will also be part of the discussion there.
