Parts for the
New Process 435 Transmission
|
The NP435 has proven to be one of the best transmissions ever built. Their unique design influenced a generation of transmissions to follow.
We offer nearly all parts at the component level, and our master rebuild kit, which includes the most thorough collection of parts offered anywhere.
The Master Kit
Our master rebuild kit has been assembled for our customer's rebuilds as well as our own. It is the most complete kit we know of. It features all the typical consumable and wear item components, and includes items that are not usually supplied by others, such as the selective front shims, top cover rebuild kit, updated 3rd-4th synchro ring assembly, fork inserts, etc.
Rebuild Requirements
It is very common for our customers to do top-level rebuild work, using good methods and by following our included instruction guide.
We suggest the rebuilder have access to a set of snap ring pliers, and a small arbor press, in addition to standard shop tools.
Other Components
Essentially all parts for the NP435, including gears, shafts, etc. are available new and affordably so. Contact us.
