5. The final page of this post is the Monarch Type TUL and UHL Parts List document and was printed on a legal-size-length of paper:
As I’ve stated before, (I’ve lost count how many times I’ve said this) The Monarch Hydraulic pump is my favorite, reliable and easy to work on. I rebuilt one of these on my CJ5 30 years ago, without any experience, took me about an hour to get the job done. Want to add power angle, no problem, just mount another valve on top, less then 10 minutes and you’re done.
The Monarch setup never failed me over many years of plowing in NJ.
Just as Arthur Godfrey did, If asked I would endorse this product for FREE, now that’s Quality.
Great info. We often get request for information on the Monarch pumps. Going to add a link to this on our pump page.
