622.5cc JONO & JOHNO VERTICAL SHAFT ENGINE

Top of the range, 622.5cc vertical shaft engine. 1 year warranty.
Equal to any brand name engine on the market today.

There are a few things you need to check before purchasing any vertical-shaft engine to ensure it fits your mower.

BOLT PATTERN:
Our engine has a Briggs & Stratton bolt pattern. You can view a schematic of the bolt pattern in our thumbnail pictures. If you have a Briggs engine then the bolt pattern will be a perfect match. All four mounting bolt holes are threaded. M10 x 1.5x 70 (bolts not included).

If you are switching from a v-twin to a single cylinder you may need to drill new bolt holes in the chassis.

OUTPUT SHAFT SIZE:
The output shaft on our engine is 1” (25.4mm). Almost all ride-on-mower engines with a HP rating between 9hp and 18hp will have 1” shafts. The thread pitch for the output shaft is 7/16 20 UNF -2B.

PHYSICAL SIZE OF ENGINE:
If your mower has only a limited amount of space for the engine to fit into (i.e. it is under a bonnet) then you will need to check the physical dimensions of our engine before purchasing. A schematic of the engine’s physical dimensions can be found in the thumbnail pictures of our listing.

PLEASE NOTE: THIS IS AN UNIVERSAL FITMENT ENGINE AND SOME MODIFICATIONS TO THE MOWER MIGHT BE NEEDED, INCLUDING (BUT NOT LIMITED TO) THE MUFFLER AND EXHAUST SYSTEM.

FEATURES:
Optimized balance system, vibration reduction and more stable operation.
Overhead valve (OHV) design and lower engine temperature
Secondary oil filtration system enables better lubrication of engine, reduces wear and prolongs engine life
Cast iron casing does not only effectively improve lubrication, but also makes engine more resistant to wear and prolongs engine life
Metal cam and forged crankshaft makes engine more reliable and durable.

WARRANTY OVERVIEW

Jono & Johno offers a 12-month warranty on most products.

We pride ourselves on selling good quality gear and will be fair and prompt in honouring our warranties. If you’re in trouble, we’ll help you out.

WHAT IS COVERED?

The exact warranty coverage depends on two factors:

Whether the fault is due to user error or a manufacturer defect
Whether the fault is minor or major

Minor faults caused by the user

Parts will be supplied for repair at the user's expense.

Minor faults caused by the manufacturer

Customers are expected to perform basic repairs as part of our warranty process.
Jono & Johno will provide replacement parts and instructions for simple repairs, such as installing a recoil starter.
Jono & Johno will determine whether a fault is classified as minor.
If unsure about a repair, contact us, and we’ll assist you.

Major faults caused by the manufacturer

Jono & Johno will arrange a return, refund, or replacement at our expense.
If preferred (and at our discretion), we may provide replacement parts and contribute to labour costs if you can perform the repair.

Major faults caused by the user

Where possible, parts will be supplied at the user's expense.
If the item cannot be repaired by the user, we offer repairs at our workshop at $80 AUD per hour.
The customer will need to cover return shipping costs for user-related faults.

If you need to return your product:

In-store return: If you're near a Jono & Johno outlet, you can return the product in person. Contact us first to arrange a return authority.
