Compression Tester

[Hay maker2]

What is everyone using for a compression tester for the 10/20 series with the pencil injectors?
Maybe a universal tester that will also work on the 30, 40, & 50 series?

thanks

I have an OLD Bacharach compression tester with several injector adapters, including the pencil injector head.

I have a set like this one: https://www.ebay.com/itm/401214600647?hash=item5d6a40f5c7:g:LaYAAOSwa0ddl-gF It has the adapter for pencil injectors and I made adapters for KDL and KDEL injectors using one of the other adapters and the gland nut from the appropriate injector.

Hay, Check out the Special Tool number in the specific John Deere Tech manual. I got a tool/adapter years ago from JD. I don't have the part number but they may still be available. Also
check with some high quality tool companies online for a specific adapter which will hook up to a multi-purpose compression pressure gauge.
