Cropmaster Diesel Fuel Pump Coupling failure

Post by broadsword » Sun Dec 04, 2016 8:16 pm

The plastic/rubber fuel pump coupling has collapsed (ie nowt left!!) on my Cropmaster diesel. It is the earlier type ie not direct drive - in other words the same system as the Fordson Major / Nuffield.
Is it a fuel pump off job to replace the coupling (fit a new one back) or can it be done with pump in situ - also will it need timing back up??

Thank You

Andy

The pump has to be moved back enough to enable a new disc to be inserted. Fuel pipes etc have to be removed. The pump should not require retiming. The discs are available from davidbrown parts.
Some tractors have had the couplings changed to the Simms unit to reduce noise. This has a star shaped rubber centre disc.

Thanks for the info db2d. Part ordered, the old gals being moved to Howard Crawshaws today to have the job sorted.
I assume its a DB system - it was always chattering/noisy anyway, hope so, there is nothing left to compare it to.
Will it be covered under warranty is what I want to know - you don't expect them to fail at 65 years of age... :wink:

Warranty claims would have to be supported by a complete genuine service record similar to the used car trade.
