Dorman – Power Transfer Unit Assembly (Part No.600-234XD)

Power Transfer Unit Assembly

from

$1254.99
Hearing a weird metal rattling sound, or smelling a strange gas scent, coming from your power take off unit? The factory PTO on certain Ford, Lincoln and Mercury vehicles often fails when extreme temperatures cause internal lubrication issues. When the lubricant overheats, it can cause catastrophic failures, also making it nearly impossible to salvage and rebuild it. In extreme cold, the factory seals fail and cause oil to leak from the unit. This patended Dorman OE FIX PTO has been redesigned for greater resilience to thermal extremes, with an added heatshield to reduce internal temperatures, and a drain plug for easier servicing of the gearbox lubricant. It also includes upgraded seals to prevent premature degradation in extreme cold temperatures, providing an all-around more reliable replacement. For vehicle owners, that means you don’t have to worry about the same problem again soon. For fleet managers, that means lower maintenance costs and less downtime..

Product Features:
  • Improved design – this patented, 100-percent newly manufactured PTU has been redesigned to increase durability compared to the factory part on certain Ford, Lincoln and Mercury vehicles.
  • Greater heat resistance – incorporates a heat shield not found on the factory part that reduces heat transfer to the gearbox lubrication by up to 30 degrees Fahrenheit to prevent thermal breakdown
  • Greater cold resistance – seals are made from an improved material to withstand temperatures as low as -40 degrees Fahrenheit and help prevent future oil leaks
  • Added serviceability – includes a drain plug to allow for easier routine servicing of the gearbox lubrication compared to the original design, further helping to prevent future failures
