Hi Everyone,
I secured a used PTO for my M43. I realize that the ambulances normally did not come with a PTO. I was reading in one of the manuals (TM9-8031-2) that if a new PTO needs to be installed, it and the transmission need to be removed and replaced as an assembly. Does that just mean the PTO can't be installed with the transmission in place or does it mean that there's a different transmission required for use with the PTO? I thought that the M37/M43 shared the same transmission and that the PTO was swappable.
Also, curious if anyone has used their PTO to drive anything else other than the stock winch?
thanks!
Justin

The PTO can be installed without removing the transmission, but it is extremely tight quarters to do so. The worst part of it is that it must be properly shimmed to achieve correct drive gear backlash adjustments. That may well cause you to have to install & remove it several times before getting the right number of shims for proper backlash. It's worth the trouble to pull the trans in my opinion. You can use the PTO to drive any accessory you want as long as you properly install a good drive line.

Charles,
again, thanks for sharing more of your wealth of knowledge. I think I will save the PTO install for when I strip the truck down completely. I look forward to figuring out how to drive my intended accessories. I'll definitely use the same drive line as for the winch, but maybe place a pillow-block type bearing at the end and use a shaft with a spline at the end. Should be fun!

PTO Shim
How would I know when it is shimmed correctly? What should I look for - or is this a job best left to someone with the correct tools?MSeriesRebuild wrote:The PTO can be installed without removing the transmission, but it is extremely tight quarters to do so.
