Briggs and stration quantum parts

HI.

can any one tell me do all quantum engines share the same parts ie: crankcases and pistons.

 

thanks john.

Not if they have different displacement I presume

Alas, No.

Although there are very many common parts there are also several differences.

One example is the crank, which comes in different diameters and stub length.

Pistons vary, as do conrods.

The sump oil seal is pretty much always the same.

 

Its essential when ordering spares to quote the Model, Type and Serial numbers.

Mountfield ones are different to hayter ones due the drive works off the engine on Mountfield ones. The covers are more universal and service items.

 

Good engines tho

thanks for the info...

 

what i have is a good old hayter 56 with a quantum engine with side pto but the cylinder and piston are badly scored beyond repair/rebore.

 

looked on ebay for parts but with no part numbers from the sellers i can not cross Reference.

 

been offered a Briggs and Stratton Quantum XTE 50 and im now wondering if i can fit my old quantum sump with the pto to the xte.

 

thanks again for any info.

I think you may be missing the gear drive on the crank. I did something similar years ago and had to use the old crank rather than the better straight drive one.

theres never a easy fix is there...

 

think i will wait for a complete engine to fit.

 

 

again thanks..john.

just an update..bought s/h quantum engine and swapped the sump's over and all is good. even the crank bottom was the same...but thanks for making me aware of all the differences..

the worm gear for the side pto is on the camshaft for this engine.

 

all the best john.
