Norton Tensioner Backing Plate, Thick
A thick-style tensioner backing plate for the timing chest, part number NMT2218A.
NMT2218A is a tensioner backing plate, the thick version, that lives in the timing chest area with the crankshaft, connecting rods, camshaft, and timing gear. It's a mounting plate that sits behind the chain tensioner assembly, giving it a solid seat against the engine casing.

Our catalog shows this one appearing across a couple of entries spanning the early 1970s, but we don't have enough detail on file to tie it to one specific model or engine size. If you're rebuilding the timing chest and need this exact plate, it's worth double-checking against your engine before you order, since "thick" suggests there's a thinner counterpart out there and mixing them up will throw off your chain tension setup.
Give us a call if you want to confirm fitment on this one - the catalog record is a bit thin and we'd rather get you the right part than have you guess.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
